Does the Nexus 6P get too hot?

A lot of pixels have been wasted — and I do mean wasted — on the thermal conditioning and overall performance of the Snapdragon 810 processor. It's been such a hot button (see what I did there?) issue OnePlus went out of their way to ensure everyone they had a special "cool" version of the processor, only to have it come out later that so did everyone else. That's not to say there haven't been phones out there to run poorly while packing a Snapdragon 810, but as we've seen with several other phones that has more to do with manufacturer competence than anything else.

With the Nexus 6P packing a Snapdragon 810 under Huawei's slick exterior, there's a lot of folks out there with questions about performance and thermal properties. Does the Nexus 6P handle heat poorly? You be the judge.

Earlier this year we stuck the HTC One M9, the Samsung Galaxy S6 edge, the LG G4, and the Motorola Droid Turbo under a thermal camera and took some pictures while making each phone jump through hoops. During that test we learned that these phones only really get super hot during benchmaking periods, but the metal body of the HTC One M9 actually did wonders for dispersing heat and making the phone comfortable to hold under load. It seemed only fair to subject the Nexus 6P to a similar set of tests.

In our 76-degree (Fahrenheit, of course) office, the Nexus 6P started out at 81 degrees. That was the phone sitting on a table doing nothing for at least half an hour, so well into a Doze cycle. Starting out, the Nexus 6P was picked up and played with for ten minutes. Five minuted browsing and checking social media, and five minutes playing Ski Safari 2. When the Nexus 6P went back under the Flir thermal camera, it had climbed up to 99.2 degrees. As you can see in the image above, heat buildup happens mostly between the camera and the fingerprint sensor, which is good news if you're holding the phone in portrait but not quite as good if you're playing a game. Still, under 100 degrees is nothing to worry about. Under these same conditions, every other phone we've tested behaves similarly.

The bottom line? You aren't going to have heat problems with the Nexus 6P.

Benchmarking is where things tend to get interesting. In our last test, parts of the Galaxy S6 edge (with its Exynos processor) climbed as high as 120 degrees and was noticeably uncomfortable to hold. The Nexus 6P immediately jumped to 102 degrees when the benchmark started, but never got above 104.5 degrees during the benchmark. At this point you could feel the fingerprint sensor area was a little warm, but the rest of the phone was still plenty comfortable to hold. Running the benchmark again saw the temperature climb to 106 degrees, but never any higher and at no point did the phone give any thermal warnings.

The bottom line? You aren't going to have heat problems with the Nexus 6P. It gets just about as warm as everything else out there, but at no point did the phone feel unreasonably hot. In fact, it stayed cooler than Samsung's offering by 10 degrees without sacrificing performance. We can't ask for much more than that.

  • Thank you for writing these articles that address issues people actually care about.
  • Facts Posted via the Android Central App
  • Seconded. AC, you have integrety because you provide genuinely useful content, not just cheap junk-food content.
  • Cool! (See what I did there?) This is great news!
  • I'm curious to see what the 950XL will do with its liquid cooling system. I remember where Richard said the Z5 almost got too hot to hold when recording in 4K. Recording in 4K I wonder how it will do compared to the Z5. Posted via the Android Central App
  • I'm more curious about internal temps. The outside could be cooler because they're insulating the case better. For example my 801 Xperia Z3 hit 60C+ playing Tales from the Borderlands last night.
  • Heatpipes aren't technically liquid cooling. If they were, nearly every single desktop PC and laptop would be considered liquid cooled. You are still relying on the air to passively cool the heatpipe. And I'm just going to guess there's no fan in there... Lol. As blogs are simply stating these phones use the same cooling as the SP and go on to note how the SP has a fan. Posted via the Android Central App
  • He is talking about the Lumia 950XL having liquid cooling, not the Z5
  • It's still heatpipes. Marketing +1 apparently. Posted via the Android Central App
  • In a technical sense, it is liquid cooling because there's a phase change taking place inside the heatpipe. We're into the semantic weeds at this point, but it's certainly not as simple as just saying it's marketing.
  • Sure, but its not "liquid cooling" as any PC guy knows it. Any good aftermarket CPU air cooler has heatpipes. We all know they are calling it liquid cooling to try and sound cool and more extreme. ;) Companies who make laptops wouldn't market this as liquid cooling cause we all know better. Posted via the Android Central App
  • OK seriously, one uses liquid, others don't. Calling the one which uses liquid "liquid cooling" is legit, regardless of how the system performs. By your logic, the liquid cooled PC you have isn't really liquid cooled either, those are just heat pipes, eventually cooled off by air. The nuclear reactors in submarines aren't liquid cooled either, the entire ocean is a heat pipe for them, eventually cooled by the cosmos.
  • As mentioned, the new Lumia's are liquid cooled around the processor. Posted from my Droid Turbo
  • The luminas, like all PCs, are using a heat pipes (which are great). There is liquid involved but its not what we'd typically call liquid cooling.
  • What will you call liquid cooling then?
  • Liquid cooling involves pumps, a reservoir, a radiator and fans. You know what helps make a good air cooling CPU cooler? Heatpipes. ;) Posted via the Android Central App
  • oohh the wit. The liquid circulating in the copper pipe. The Huawei will does not.
  • Every LTE phone I have ever owned gets extremely hot when Uploading over LTE like large photo albums and videos. Even more so when I charge it while uploading, because uploading large data packs eats and drains my battery.
  • Sony phones have had gel cooling the same as the 950 for some time now. Posted via the Android Central App
  • this phone is perfect IMO, or at least as close to it as I've seen. I've never used wireless charging, so maybe I don't know what I'm missing, but stock, a nice premium design, front speakers, a great camera and most importantly solid battery life, this thing is the 'best phone ever made my Android," a quote from Wired, the biggest iphone fanboys out there!
  • A lot of the tech media has been saying its the best Android phone ever these last few days. And they're right because of the combo of hardware/software, premium build, great camera, and the speed of updates it gets from Google.
  • We shall see but there is a lot of hope... +++ Insert witty signature, watch as others not get it, profit +++
  • we are seeing it. the same was true for nexus 6
  • Agreed I wonder if illiterate people get the full effect of alphabet soup
  • nah, the nexus 6 was cool but this is on another level, I mean, even iPhone people are raving about it ... Nonexus might even get one cause he loves cameras and this thing is legit. And even if not, at least he and a lot of people will start to take nexus a lot more seriously as an option.
  • I have taken the nexus seriously since the 5, but the camera and the software, initially, were seriously lacking compared to others. I have hopes that both are worked out for the 6p, the 6x makes me kinda leery though but that is a different phone. +++ Insert witty signature, watch as others not get it, profit +++
  • The 6 was very nice but still very flawed in the camera department. +++ Insert witty signature, watch as others not get it, profit +++
  • Disagree. The nexus 6 was not even compelling. It will be quickly forgotten unlike the nexus 5. Posted via the Android Central App
  • The 6 is great. It's better than the 5 in almost everything. However, it never got as popular due to the humongous size and expensive price tag.
  • Ya, that's just ridiculious
  • yeah it's really getting amazing reviews ... I can't recall any phone, iOS or Android, to have ever received such overwhelmingly positive reviews
  • Definitely isn't the best looking phone...
  • Always gotta be somebody to rain on the parade! Posted via my Nexus 6
  • personally I love the aesthetics, though that's something I don't really care much about. I hate when cameras protrude like on the 5x and I think the contrast on the frost with the black bar looks cool. love the graphite, but ultimately it's a moot point since I'll have a case. and the front, I wouldn't mind if the bezels were a bit smaller, but I like how it's all black and no branding, plus I can deal with a taller phone, it's width I dislike.
  • Certainly not. And most people thought this way based on the leaked renders. But the fanboys need a nexus to drool over and it sure ain't gonna be the 5x. Posted via the Android Central App
  • Or maybe the hype train is fanboying out? Solid phone no doubt, and maybe the best nexus ever, even if not the best looking. But the best android phone ever? That's so subjective, but we can say there are phones with more power(ram), better cameras(ois anybody?), more software features, more hardware how are we measuring "the best"? UI fluidity? Temperature during heavy use? Come on. As good as this phone is, I just don't see how one can objectively call it the best on the planet. I will say it's the first nexus that really stands with the best pound for pound, in every area. And that's great. Posted via the Android Central App
  • I've never used fast charging so I don't really think it's a big deal. However, I have used wireless charging (N4 and 5) and I really wish these phones had it. My phones pretty much always last a day and I plug them in at night, that's why fast charging doesn't really mean much to me. Wireless charging is more convenient simply because you just plop it on there and it starts to go, there's no searching around on the floor to find out where the cable fell or fumbling around in the dark trying to get the cable inserted. I think it will be interesting to see if fast charging makes me forget about missing wireless charging. Posted via the Android Central App
  • Yes but remember in their Reddit AMA, the Nexus team brushed aside these concerns when they said that the USB-C solved all of reasons that wireless charging was needed because the port is "reversible" so you don't have to struggle to plug it in in the dark.. </sarcasm>
  • Thank you AC! Cannot wait for your full review! Posted via Android Central App
  • Instead if just writing celsius in brackets the author writes, (Fahrenheit, of course) to make the international readers google fahrenheit to celsius. And I think you mean benchmarking and not benchmaking.
  • I don't think I have ever witnessed anyone convert Celsius to Fahrenheit on any European publication. On these publications I don't see any American readers crying in the comments section either.
    Also, I think you meant Instead of, rather than "Instead if"
    Cheers, or whatever you say in your country. Wanker
  • No, he said "Fahrenheit, of course" because no one ever sets their thermostat to 76° C.
  • I like to keep my thermostat at "nearly boiling" (76C). I can just leave a bottle of water on the counter and in twenty minutes I can make the perfect cup of tea. Sleeping is kinda hard though. The bleeding aside, it's just too hot to sleep with a blanket on. I'm probably the exception though, so you're probably right.
  • lol!
  • I imagine there's some throttling going on to keep it from overheating. How did the phone do performance-wise? I'm especially curious how it did against the LG G4 or some other SD808 phone.
  • Did you read the last paragraph? Specifically the part about not sacrificing performance? The bottom line? You aren't going to have heat problems with the Nexus 6P. It gets just about as warm as everything else out there, but at no point did the phone feel unreasonably hot. In fact, it stayed cooler than Samsung's offering by 10 degrees without sacrificing performance. We can't ask for much more than that.
  • I'm guessing that because the 6P is a larger phone of metal construction, the increased surface area and the material should help with the cpu temps.
    I'm sure a huge wave of data will be revealed shortly as more and more people get their hands on the 6P Nexus 6
  • Well it completely destroyed the 808 5x in this comparison below. Which I really wasn't expecting. I haven't seen any 810 phone perform that well in all the side by sides I've watched I do think there could be something wrong with the software on the 5x at this point. Either that or forced encryption is taking its toll on performance
  • I tend to agree. On previous devices, the 808 held its own pretty good against 810 devices. Completely different result here. It's not throttling related, cause even the other comparisons were just opening Apps. Posted via the Android Central App
  • As someone who has owned multiple 808 and 810 devices, it's quite obvious to me in daily use that the 808 is slower. There are just a lot more pauses and stuttery scrolling on the LG G4 and Moto X Pure I'm using currently compared to the One M9 and OnePlus 2. Granted, the M9 and OnePlus 2 only have to push 1080p screens, but still, the difference is noticeable. I don't think the 808 should be in any phone with a QHD screen, and even pushing a 1080p screen I think it's a mediocre chip at best. My Nexus 6 with an 805 is noticeably smoother than my G4 and Moto X Pure.
  • What you're seeing there is most likely a combination of an extra 1GB of memory (more apps cached RAM), faster memory (launch those cached apps faster), and a faster CPU (theoretically better at encryption performance, but this isn't proven). This particular test favors the architecture of the entire device, not just the 810.
  • You're forgetting something important; LPDDR4 memory for 6P instead of LPDDR3 for 5X. Posted via the Android Central App
  • No I didn't, I specifically called out the faster memory.
  • You wouldn't be seeing those same results with the one original nexus 5. I guarantee it. And it has 2 gigs of RAM and a technically inferior SoC as well. I'm familiar with the sort of hang that you see with encryption, like slight delay re-opening apps that are already in memory. That's what the 5X has shown so far
  • My LG G4 gets so hot so quickly, can't wait to get rid of it for a 6P next week.
  • Frying pan, fire.
  • Really? What do you do on your phone? I have the G4 and it's by FAR the coolest phone I've owned for a while. My Note 4 was toastier than this G4! I'm not a heavy user though... But on my Nexus 6, Lumia 930 and Note 4, they all got HOT and FAST. I haven't felt one warm spot on my G4 :\
  • I'm not a techie, but according to a monitoring app the battery (not the processor) of my 6p immediately goes into the high 90s F just surfing on Chrome.
  • There probably is a small amount of throttling going on there, but not much, considering it's still faster than the 5x, shown by the video by android central. Posted on my Galaxy s5
  • Like that means anything. My grandmother is faster than the 5X. And she's dead.
  • lol, yeah the 5x kinda sucks from what I've seen ... passing up the 6p just for the smaller display is a pretty big sacrifice
  • It's not supposed to be blazing fast, it's supposed to be good for the price. Posted on my Galaxy s5
  • Then why is it slower at opening apps than my nexus 6? And it absolutely should be blazing fast it's 2015 we shouldn't have this problem anymore. Posted from my Nexus 6/Nexus 7 2013/Surface Pro 3
  • Don't get me wrong, it probably should be faster, but keep in mind the 808 only has 2 powerful A57 cores and they aren't even clocked that high, plus a weaker GPU. The 805 is still a great SoC. Posted via the Android Central App
  • You probably killed her Posted via the Android Central App
  • My M9 gets really hot if I'm playing a graphic intense game and charging at same time. I never measured the outside, but the battery would get up 138 degrees F, so outside had to be over 120. But it would only get that hot under that scenario. So I imagine my Nexus 6P will do the same. Posted via the Android Central App
  • I'd like to see what Google did to optimize the firmware on the 6P. I doubt they had any option to work with Qualcomm to optimize the 810 in any way for the 6P. Other phones have had some serious issues with this chipset. But from what I've seen the 6P is crazy fast and handles workloads as good as anything else. I wasn't expecting that to be the case but I'm glad it is. Whatever Google did it looks like it worked at this point. The verdict could still be out though. There's gonna be a lot more comparisons between the 6P and others in the next couple months
  • Probably has alot to do that it doesn't have the extra coding/skin to have to deal with. Just my assumption. Posted via the Android Central App
  • I don't know, but I have seen and read from a few sources that the 1+2 has had some performance/speed issues and it should be a speed demon running on oxygenOS
  • On oxygen? No way. That skin is a cluster +++ Insert witty signature, watch as others not get it, profit +++
  • Maybe its not as optimized as stock CM, but the official CM builds and even the nighties fly. Its fast as hell
  • Oxygen is not equal to cm. Oxygen is more like sense but built like lg +++ Insert witty signature, watch as others not get it, profit +++
  • Also through into the mix is the 810 has been out for sometime now, I'm sure they may have made some improvements on the chip fabrication to help with the heat.
  • If they changed it, it would have a new model # or revision. Posted via the Android Central App
  • Boom. /thread on the 810 in the 6p. Thanks AC.
  • "It stayed cooler than Samsung's offering by 10 degrees without sacrificing performance" I don't think so. Benchmarks of the 6P show that it's slower than other 810 phones. Also, it gets even slower when the benchmarks are run over and over again as opposed to a fresh start as you did. Clearly, there is throttling going on as the temperature rises. This is only going to be a problem if that throttling drops the performance to the point where you actually start noticing it (lags, skipping, dropping frames etc.). Benchmarks that are unnoticeable aren't going to matter compared to overheating which would definitely be noticeable. If the performance does drop, another phone ruined by the 810.
  • "Clearly there is throttling going on as the temperature rises" Yep, just as it should do to prevent damage to the device. This is normal operating procedure for mobile devices. Show me an Android device that doesn't behave the same way. Also, throttling is done to prevent overheating. Those two things are not the same.
  • Yes but there are two types there, normal and aggressive. You only use aggressive if needed and the 810 spends a lot of time there +++ Insert witty signature, watch as others not get it, profit +++
  • That is an overly simplistic way of attempting to explain it. "The 810 spends a lot of time there" ^^ There is far more to heat dissipation than the SoC. I bet the 810 has very different points of throttling in the G Flex 2 versus the HTC M9 versus the OnePlus 2 vs the Nexus 6p.
  • So you're saying that's not what a subject matter expert would say?? Lol
  • There is a lot to heat dissipation but it all starts with the heat source itself. +++ Insert witty signature, watch as others not get it, profit +++
  • Can you post those benchmark sources? I just wanna check them out. And just FYI, every phone, tablet, and computer chipset throttles to manage heat
  • I can't recall where I saw it. The ones on Phone Arena are comparing the Nexus 6P to the Note 5, but that's using the Exynos SoC. I did read on another site that they found D that the benchmarks got progressively worse when they ran them repeatedly a number of times. Of course the 6P is throttling to prevent over heating. That's exactly what I'm saying. That, unlike what the author said, there seems to be throttling when the phone is stressed (while running benchmarks over and over).
  • You might be confusing down clocking and thermal throttling. Basically all modern computers and mobile devices drop the core clocks when they aren't needed 100% to reduce power consumption. That has nothing to do with thermal levels. Thermal throttling is essentially forcefully reducing the ceiling to control heat. All computers and mobile devices absolutely do not thermal throttle. Alot of mobile devices and laptops might, but not PC's. If your PC thermal throttles, you have massive cooling issues and your probably ruining it honestly... The commonly accepted "safe zone" for desktop CPU's is well below the thermal throttle temperature. Posted via the Android Central App
  • Yes, clock speeds decrease when they're not needed to save power obviously, but I wasn't talking about that. I was addressing thermal throttling. Maybe if I'd have written "In part" in there somewhere you wouldn't have felt the need to state the obvious. I've experienced throttling plenty of times on PC's that are a few years old. Of course there's less of a need for it with the standard hardware out today, but it still exists when you push a PC to its limits
  • Well, every computer CERTAINLY doesn't thermal throttle. The ability is there, but if you actually reach that point, your CPU cooler probably fell off or you have no case airflow. I promise you my PC has never thermal throttled... Lol. It's not so much stating the obvious. It was more of you were either incorrect or didn't properly word your point. Posted via the Android Central App
  • Wonder how this compares to my Nexus 9 tablet. It gets hot enough when playing Hearthstone that I have to flip it occasionally to hold it on the cooler side.
  • 810 on any other phone - "this phone is terrible, it throttles and overheats! [Insert stupid toaster remark here]" 810 on the 6P - "This is the greatest phone ever! Can't believe how fast it is! Posted via the Android Central App
  • Yeah im not totally convinced. The 810 is such a fiasco that it ruined potentially great devices like the G Flex 2 and the M9. I wanna hear from themany users who will have it in hand hopefully soon. Posted via the Android Central App
  • Looks like Google figured it out. We will have to wait a couple months with real world results to find out however. Posted via Nexus 6 running on any data plan I want
  • Google? No. Huawei
  • Google gives them the design they build it, so yes Google
  • a lot of it, most of it actually is software related, so yeah, it's google that would be responsible. and none of us know the exact process, but I'd think huawei has a lot of input on the design. Google probably gives them the parameters then approves the final design. They both deserve credit, but Google much more so
  • Well, it could be the passive cooling, as well. Maybe I've missed it, but have we actually heard if this has any heat pipes or larger heatsink anything? Posted via the Android Central App
  • Google designed a really similar phone to all other Huawei handsets... Posted via Android Central App
  • Like I said before, if the 6P (or any other Nexus) came without a battery, people would be praising it for being so much lighter and they want to keep the cord attached 24/7 anyway! It's so easy, because you don't have to worry about which way to insert the cable!
  • That's actually pretty funny, but I think you're reaching a bit there. I love nexus phones just as much as anyone, and a lot of us, at least the ones on the AC forums have been fairly objective. I've been pretty critical of the 5x, and the 6 last year had quite a few flaws imo ... other than the wireless charging, which a lot of us never experienced, it's pretty much got everything you can ask for if you like stock. Camera and battery are two of the biggest features, and this is the first nexus that delivered both, so I think it's fair for people to be excited, especially priced significantly lower than last year. Android Police, your statement would be 100% accurate there!! Ultimately this is a great phone that a lot of people will enjoy. I don't think they're really gonna care what the few people that bash it just to bash it think or say. When iPhone fanboys are singing its praises, and they are, you know you have a solid phone on hand.
  • Yeah, with a couple exceptions, AC forum participants are sane. AP, on the other hand, is Nexus fanboy city. I got banned there for criticizing a Nexus. David Ruddock is also a pansy-ass whiner who can't take criticism. His "scandal of the week" always cracks me up. He thinks he's going to win a Pulitzer for finding out a phone has a bad pixel.
  • Dave is an idiot, and I'm not surprised they banned you. AP is a joke ... End of the day, these are phones we're discussing, not exactly something to be taken seriously. How boring would it be if we all had the same opinion.
  • Haha where are all those people who swore this phone was gonna get super hot? Posted via the Android Central App
  • still commenting here out of jealousy denying everything Russell just wrote
  • Let's hold off til it's in consumers hands and we can confirm it isn't throttling. Posted via the Android Central App
  • Starting to have buyers remorse. Bought my N6 two weeks ago, was worried about the 810. This might be the best Android phone ever at least until next year. I might have to treat myself to a early Christmas present. Posted via Nexus 6 running on any data plan I want
  • Same here. Just got my Nexus 62 weeks ago and now I may have to save up for the 6P. Posted via the Android Central App
  • Huawei has tamed the dragon!
  • Google has. Posted via the Android Central App
  • You saying Google gave them a special version of Android they wouldn't share with Sony, HTC, LG, Samsung, OnePlus... Lol OnePlus claimed to have some special software tweaks and they still had to drop the core clock on the A57 cores. I'm leaning toward improved passive cooling. Posted via the Android Central App
  • Doesn't matter who did.
  • Tech journalist writes article showing there's no issues.
    Readers who aren't buying the device ignore it and comment about issues anyway
    Rinse, repeat on pretty much every tech article anywhere just to create drama for phones you're jealous of because it's more fun than sober explanations. How's that for a benchmark?
  • Cynic much? Posted via the Android Central App
  • some people love being miserable ... they're just more comfortable being negative, and I'm sure that's how they are in the real world too .... aesthetics or size, go ahead and state your opinion, and some people might want wireless charging, and I have to respect those people's opinions. But yeah, bashing it just cause your miserable, either they're immature, insecure, or just hate their life
  • So hot that you can cook an egg Posted via the Android Central App
  • A mod of the thermal files fixes the heat problems just shoot me a pm of your thermal files and I'll mod them for you on XDA @robshr
  • So, sure, like most phones get warm, but maybe even less so! Thanks for your efforts!
  • Time to face the facts. A hot phone can actually be benefIcial during the winter time. Plain and simple noting and I mean nothing beats the feeling of picking up a warm and toasty phone with cold hands. Posted via the Android Central App
  • I can name at least one other thing that is warm that I like to hold in the winter more than a phone.
  • Wrong 6" device bro Posted via the Android Central App
  • Really? Dam It Feels Good To Be A Google Gangster
  • Haha Posted via the Android Central App From my Blackberry Priv where I am out of toilet paper
  • So did performance on benchmarks drop the more you ran them? If it matches the Exynos in throttling, that will be a big improvement already. Posted via the Android Central App
  • Yay good news Posted via the Android Central App From my Blackberry Priv where I am out of toilet paper
  • The question is not whether or not it gets too hot but whether it throttles to unacceptably low speeds due to the heat. Does the 808 outperform the 810 after 10 minutes of heavy use or gaming due to throttling? That would explain the cooler temps but would be a bad reason for the cooler temps. Yes I read the last paragraph.
  • Bingo. Posted via the Android Central App
  • promising, and I care about real life, not benchmarks, but yeah, I'm anxious to see for myself next week and see what everyone else with it has to say .... did u get one?
  • Games are just as intensive as benchmarks. Pushing the GPU will actually cause more heat than just a CPU only benchmark, too. Posted via the Android Central App
  • He did not start that fire, and neither did the Nexus 6P.
  • I had a S6 edge and it was one of the coolest phones I've ever had. Even trying my hardest I could barely get the battery to 40 degrees celsius. But then again I had to restart the phone multiple times daily because of software jankiness so who knows lol
  • I was using my mom's note 5 2 weeks ago, she was on vacation and I'm waiting for my 6p, so used her phone for the week ... very minimal heating and I ran it hard. lot of clash of clans, lots of YouTube, and streamed music at the gym 3 nights. Heated up a bit ob clash of clans, also I took a video of my son skateboarding and it got kinda hot, but nothing alarming at all I'll be pretty happy if my 6p has similar heating .... and I didn't get too much lag, some, but nothing an average consumer would notice. I don't run multiple apps that often though, so might not be a fair assessment
  • Brain exploding from all the yo momma jokes rushing in here, lol. Posted via Android Central App
  • With a temp that low after benchmark test (a sd810) its got to be throttling.
  • Snap-toaster Dam It Feels Good To Be A Google Gangster
  • All phones have some throttling going on, it's just a question of how much, and most importantly, how it affects real world usage ... From what I've seen so far, even from iPhone fanboys, it's a non issue. If true, and ultimately I'll judge it for myself next week, I'll be interested to know exactly what Google did to prevent the heating issue. I doubt Qualcomm did much, but I really don't know. I'm interested to find out, and hope AC or anandtech digs deep and gives us good feedback. Surely if there are benchmarks that show significant throttling, the trolls will be out in droves!! probably deservedly so. But I'll be an owner, so I'm much more concerned with real life experience!
  • Nah, I can tell when my Note 4 thermal throttles while playing games. It's a real issue. The Sony Z3+ actually force closes the camera App when it overheats. That's not a non issue. Posted via the Android Central App
  • Thank you for this review! still better smartphone than samsung 6 edge, eh?
  • Idk if it's throttling. Someone tell me if this is the case. The new Hamilton Beach SD toaster. Powered by the Snapdragon 810.
  • It has to, there is nothing in 810 that we don't know yet.
  • My next phone!
  • If it's better than my GNex heating up while browsing G+ then i'll be happy... that's gotta count for something.
  • I am sorry, but I don't think I can trust this report. 1. First, it's useless to just measure temperature without measuring the throttling. And temperature of battery and CPU are different and manufacturer's use different thresholds to maintain sustained performance. 2. This is clearly not the right way to judge performance, throttling, overheating. Apple's A8/A9 are defnitely the best in this regard, with 810 the worst of the bunch. 3. Here's a much more 'valid' test to understand how the system behaves when stressed - It was told in another similar artcile last time that One M9 is 'cooler' than S6, when the whole Internet knows that it's not right. And the technicque used in that test is also flawed. What you did it simply measuring the temperature without taking into context other variables which makes the test useless.
  • Yeah, I don't know how at this stage we can discuss the 810 thermal issues and not cover throttling. Most phones get warm, who cares. Our performance is what we pay for, we want to know if we're getting short changed. Posted via the Android Central App
  • Warning: Technical overload A thermal scan is a thermal scan. The reason the A8 and A9 don't throttle much is because they are underclocked, which if you are familiar with the technical side of chip design, is a form of pre-throttling. And yes, I'm a former beta tester for Apple OS development and have done chip-level research and modifications beginning way back with the address-enhanced 6502b, but, I prefer to deal with the science side of things rather than opinion. My first article on computer thermodynamics was published nationally, and I only mention that so you know I'm not stepping into this subject with only what the internet says. The A9 SoC is clocked at 1.85 GHz, but guess what? It can run faster. Apple does not run the A9 at a higher clock rate for good reasons, and it's not because of any defect or design flaw; the A9 is actually pretty damn good. There is a balance to what speed you run your chip at. Set the speed too low and you are needlessly sacrificing performance and wasting resources. Increasing the clock rate increases performance of course (to a point), but the bad news is that it also pushes up power consumption and the amount of heat, and the rise in power consumption is non-linear. When you increase a chip's clock rate near the limit, a 10% increase in frequency can cause an 80% increase in power consumption. What works best in SoC design is finding the best frequency to run the chip at for performance, and still stay below power consumption and thermal thresholds. A conservative clock rate will be energy efficient and produce less heat, and of course an aggressive clock rate will be less energy efficient and produce more heat. Apple takes the conservative approach, which is is fine by me, but is also why the A9 is not drastically faster than processors designed a couple years ago. For reference, I'll use the SD 801 which was designed in 2013 and announced on February 23rd, 2014. The 801 runs quad Krait 400 cores, all of which are clocked at 2.5 GHz, and returns a Geekbench 3 score of 3508. The Apple A9 runs dual ARMv8 cores which are clocked at the previously mentioned speed of 1.85 GHz, and returns a GB3 score of 4527. Yes the A9 is faster than the older 801, but not by the huge margin you would expect, and this is mostly because the conservative clocking was chosen to be safe. Could the A9 be even faster? Absolutely. They could turn it up to 2.0 GHz and get even better performance, and although it would use more power, there would be little noticeable difference in heat output, except for benchmarking. So, this begs the question: Why does the HTC One M9 throttle more aggressively than other devices using the same 810 Soc? It's simple... HTC pushes the 810 closer to it's limit for performance reasons. Even though I don't own one, I have done testing on the M9, and it's a much better phone than it gets credit for. Sony tried to push performance with the Z3+ and failed because they did not combine the proper thermal controls, AND did not provide proper thermal conductance in their physical design. Now, here is where it gets REALLY interesting as we take a look at the Huawei Nexus 6P. Huawei took a more conservative approach and is using the 810 less aggressively than HTC. And why not? The 810 is fully capable of beating out every iPhone SoC that Apple has ever created, including the A9, and has plenty of performance, so why not tone things down slightly since you are using Pure Android anyway, and let the good times roll? Sounds like a good plan to me.
  • Can I say I really really love you right now for exposing and explaning to the masses this issue? You're awesome!!! I own a few HTC devices (Nexus 9, One M7, One ME) and never really had any jarring heat issues.
  • Thank you!
  • That's some really great info. It's always nice to hear from a subject matter expert. I've been wondering what it was Huawei and Google did to get the 810 to run so efficiently on the 6P as we've seen in all the comparisons so far. Thanks!!!
  • From Ananatech's M9 review: "using CPUBurn to try and load just a single thread reveals that without HTC’s CPU cheats, it’s basically impossible to get the A57 cluster beyond 1.5 to 1.6 GHz." I don't think HTC is pushing the SOC that much.
  • That's interesting, what is HTC doing to get the higher clock speed? Increased the thermal limit?? Posted via the Android Central App
  • The thermal limit is has no effect on clock speed, unless you hit it. They work the same way as a speed limiter in a car, and most people never hit that limit. HTC does not advertise any adjustment to the clock cycle reference signal (which controls CPU frequency), but they are clearly doing something to get those higher benchmark results and hit the thermal limiting quicker. The performance benchmarks are below, and all results are from primate labs who make Geekbench 3. I was unable to find scores for the Sony Xperia Z3+ and Z5. OnePlus 2: 4093
    Nexus 6P: 3774
    HTC M9: 4834
  • Well you are comparing a dual core to a quad core in a multithreaded test. The part of geekbench you "feel" far more when using your phone is the single threaded part which the A9 destroys everything out there by a factor of 2.
  • Technical overload? All I see are lots of great info and techy stuff. EXCELLENT!

  • What's all these in Celsius? Could it be added into the article please? Posted via the Android Central App
  • Why not writing in Celsius, for the rest of the world ? Not all readers here are from the USA...
    100 degrees is a lot in Celsius (boiling water to gas) , but in Faranheit it's about the same as the human body, no?
  • It's a US site. Just calc it out Posted from my Droid Turbo
  • I have, but it's annoying because it's everywhere.
  • Here ya go!
    Celsius conversion, rounded to nearest tenth of a degree.
    In the first thermal image:
    81.7 F = 27.6
    99.2 F = 37.3
    103.5 F = 39.7 In order of appearance in the remaining article:
    76 F = 24.4
    81 F = 27.2
    99.2 F = 37.3
    100 F = 37.8
    120 F = 48.9
    102 F = 38.9
    104.5 F = 40.3
    106 F = 41.1

  • Thanks Russell, this really helps. This is great info. I'm glad I have the 6P ordered.
  • Can you try it with the Nexus 6P case on and let us know if it's going to have any problem with the heat or thermal throttling?
  • Any new phone and new processor when released to the public really have not gone any real world tests until the consumers actually get their hands on it. Turning off the LTE signal as well as turning the brightness level lower helps a lot with heat dissipation especially when playing games. HTC seems to have mostly solved this issue with the One series with metal backs. It's not foolproof but the Android OS historically has never been good at optimizing heat dissipation due to the fact that carriers put their own software tweaks. Games App developers has less concern about heat but more concerned about how fast their games benchmark on a specific device. And with the pressure for manufacturers to release the latest and greatest within a relatively short cycle within the year there's not enough time to test their phones to subject to real world studies.
  • OK but what about the thirst of 810? So far, all other phones showed worse battery life than 805 or 808. via AC App on

  • If it's throttled down enough to keep cool, then it shouldn't suck too much battery. A hot processor is a thirsty processor, and putting a heat sink on it doesn't make it any less thirsty. It just distributes the heat. But throttling it does make it less thirsty. And less fast.
  • The point of a heatsink is to pull the heat from the chip itself, which will make it more efficient. Probably not a ton though. Heat makes the chip run less efficient and use more resources (power). A cooler processor is a more efficient processor, as mentioned. Posted via the Android Central App
  • Rogue Tomato is correct this time. The heat is a by-product of the energy used. Removing the heat after the fact is not the same as reducing the amount of heat created. Granted a hot chip will run more efficiently if more of the heat is taken away, but you won't see a significant power savings that way.
  • Sorry guys, but you know that we are in winter?
    how can you compare the heat of the device compared to others where the benchmark was done months ago?
  • Tests were done indoors with similar ambient temperature... right Russell?
  • rElax ...

  • Now that I know the nexus 6p can make benches (3rd paragraph) and take great pictures without breaking a sweat (see what I did there), I must have it. When is the giveaway?
  • Awesome I ordered mine yesterday this was my only big concern Posted via the Android Central App
  • Awesome. Just the kind of information I needed and expected to find at AC. Thanks! Posted via Android Central App on a N5
  • I was interested in this also after reading about the Saygus V squared having heating issues and switching processors. I'm also interested in the 6P and I was wondering about this overheating as well. Glad it's nothing to worry about. Hope this phone gets some good reviews when it comes out and by reviews, I mean from the people buying them. Great article, thanks for the info.
  • thanks, this issue was OVERdebated.
  • Wasted pixels? Lol. Talk about wasted pixels, what benchmark did you run? What were the clock speeds? What was the performance and performance over time? Wasted pixels on the SoC and thermals he says. Lol. Oh the irony. Posted via the Android Central App
  • Here's a video on how to cool down your computer. I suppose you could apply the same technique to a phone with an 810.
  • Another reason to avoid Snapdragon 810 equipped phones Posted via the Android Central App
  • Nice Posted via the Android Central App
  • It's not overheating on some devices because it's throttled. The chip running at it's normal capacity overheats. HTC, and others just throttled it to keep the heat down. Some makers used the 808 rather than the 810 to avoid the problem. I'm sure the new SD 820 will be a great chip. Anyone can make a mistake occasionally, it doesn't mean every Qualcomm chip will be a dud. And if the phones with the 810 work well and keep cool, no matter how they fix it, it's irrelevant once the user is happy with the performance.
  • I don't know about the processor, but just using Chrome and Facebook cause my 6p battery temp to climb into the high 90s F. Any use causes the entire back to be warm enough for my palm to sweat. I'm probably going to return it.
  • I am using the nexus 6p now for almost 2 months and i want to sell it but i am still waiting for htc one m10 or upcoming htc nexus ... Reason i want to sell it is because the heat coming from the top of the device i dont play games on my phone its all the times tweeter and yoi tube ... After the update i reset the device but its still the same problem its reall uncomfortable this phone is great but now i hate it because of the heat issue ...
  • Yes , I am having a lot of heating iisue of nexus 6p , in the 1st seven days of my purchase of the phone.... I have done everything from factory reset to reboot , nothing is working for me.... Plsss help me in this , if someone's knows sumthing.... Is it slow internet speed which is resulting in overheating...... I am really feedup of this at a every bad extent, can't still getting my phone more hotter, plss tell some solution to this.... Heating like can't withstand the phone in hands also and I think I made a mistake buying nexus 6p , its till now worst choose of mine , Google has disappointed me a lot....
  • Its not Google thats disappointed you on this run, it as Qualcomm . Google had no other choice than to use the modified version of the 810 because there wasn't any other chip that they could use that was top of the line. Its just bad luck I cant wait until the nexus nexus device comes out and hope HTC doesnt screw things up because I'm definitely tired of the heating issues with this thing from doing basic web browsing and just messaging.
  • Question: Have you tried doing this while tethering as well? I'm not sure if it's due to damage, but my Nexus 6P gets too hot to hold while tethering & playing games. Placing it on my wooden desk and leaving it for a while (just tethering) disperses the heat, but I'm wondering exactly how hot it is getting... Liam
