Qualcomm's dual-core Snapdragon S4 and LTE trump the quad-core Tegra 3 in our definitive AT&T HTC One X review!


What more could we possibly say about the HTC One X? After several thousand words in our first HTC One X review (plus more in Alex Dobie's take, plus the countless forum threads), we already know everything there is to know about this phone, right? Right?!?

Not so fast.

As you'll recall, there actually are  two versions of the HTC One X. The first, the one we've already reviewed forward and backward, is powered by NVIDIA's quad-core Tegra 3 system and is your standard GSM/HSPA smartphone. The second version is powered by a dual-core Qualcomm Snapdragon S4 (you'll also hear it referred to as "Krait") and sports an LTE radio for faster data speeds. The latter version is what AT&T's rocking coming May 6, and it's known outside the United States as the HTC One XL.

They're the same phone, right? Really the only difference is that AT&T wanted an LTE version, and Tegra 3 and LTE still aren't ready to play together in prime time, right? Well, yes, and no. Let's just put it this way: One of our chief complaints about smartphones has been addressed here.

That's not to say we won't be making a few compromises with the AT&T One X. But we're also finding ourselves plenty blown away. Read on for our complete AT&T HTC One X review.

The Good

The same great design, gorgeous display and excellent improvements in Sense 4 have made their way to AT&T's One X. LTE data is fast, and battery life (without being connected to LTE anyway) is the best we've seen on an Android smartphone to date.

The Bad

There's no way to turn off LTE data if you'd prefer to save on battery. AT&T's opted for only 16GB of internal storage, which stings considering that there's no removable microSD card. The battery's not removable, but that's tempered by the excellent power management.


AT&T's got itself a winner here in the HTC One X. The dual-core Qualcomm Snapdragon S4 is as good (or better) as NVIDIA's Tegra 3 platform. But it's the excellent battery life that makes this one a no-brainer.

The AT&T HTC One X hardw​are


Not much has changed on the outside of the AT&T HTC One X in comparison to its Tegra 3 cousin. Physically speaking, they're identical, save for an extra half a millimeter of height on AT&T's model. (That's something to be aware of as you're buying cases and what-not.) Otherwise, you're looking at exactly the same polycarbonate unibody shell. AT&T's opted for white, which we're very much digging after having spent a few weeks with a gray One X. But it is possible to pick up dirt and smudges. We've had no problem wiping them away, but they're definitely more apparent on the white body.


Otherwise, we're looking at the same 4.7-inch Super LCD 2 display with a 720x1280 resolution. It remains gorgeous, almost appearing to float on top of the glass. It's got the same capacitive buttons below the display. We've been flipping back and forth between the One X and a Galaxy Nexus (which has its buttons as part of the display itself), and the transition hasn't bothered us one bit.


AT&T's also got the same front-facing 1.3-megapixel camera out front, tucked to the right of the earpiece and its 52 pinholes. (OK, 51 if you're counting the one that's actually a hidden notification light -- look for it on the bottom row, six holes from the right.)


'Round back you've got the same 8-megapixel rear-facing camera in a slightly elevated housing. We're still a little concerned about scratching that lens, though the actual lens cover is recessed ever so slightly. The five contact charging points are here as well, as is the rear speaker and Beats Audio logo.


Up top you've got the SIM card tray, power button and 3.5mm headphone jack. The volume rocker's found on the  right-hand bezel, exactly where we left it, with the microUSB port on the other side.

What's under the hood

And this is where things get interesting.


First and foremost, don't get caught up in the fact that the Tegra 3 version of the One X has four cores in its CPU, while the Qualcomm version "only" has two cores in the Snapdragon S4 processor. If the number of cores is your deciding factor, you're looking at the wrong spec. Clock speed and RAM are a wash at 1.5GHz and 1GB, respectively.

So what is it about the Snapdragon version of the One X that has us all hot and bothered? Here's the lowdown:

Stick the two versions of the One X next to each other, and the Qualcomm-powered phone is ever so slightly quicker in performing the menial tasks -- opening the app drawer, folders, etc. That's not to say the Tegra 3-powered phone lags or shows any real sign of stuttering, because it most certainly does not. And chances are you'd never know there was a difference unless we showed you. But side by side, you can tell. Barely. The Snapdragon-powered One X is just a little faster at times. 

(We don't do benchmarks, but we also don't stop folks from doing them. Check 'em out here.)

But that's not really what has us excited.

Tegra 3's major selling point is that it's a graphics and multimedia and gaming powerhouse. Guess what: So's the Snapdragon S4. In fact, we've been running games that traditionally were used to promote the power of Tegra 3 -- and they've working just fine on the Snapdragon S4 platform.

And that's still not what has us excited.

AT&T HTC One X LTE speeds

AT&T's One X is using the Snapdragon platform at least in part because it's a 4G LTE device. That is, you can get 4G LTE data if you're in one of AT&T's LTE-enabled cities. Those are still fairly few and far between (Atlanta, Dallas-Fort Worth, Detroit, Houston, Indianapolis, Kansas City, New York City, South Florida, Philadelphia, St. Louis and Tampa, along with Cleveland, Akron and Canton, Ohio; Lafayette, Ind.; Baton Rouge and New Orleans; St. Louis; Austin, Texas; and Staten Island, N.Y., and other cites lighting up in recent weeks), but its LTE network is expected to take a pretty big leap forward by the end of the year. As for LTE speeds, they're pretty impressive. But then again, AT&T's network is still pretty young and certainly doesn't have the volume of customers that Verizon's does. That's something to keep an eye on in the months after this review is published.

And that's all well and good, but it's still not what really has us excited.

It's battery life that has us staring at the phone, dumbfounded. We've long talked about the difference between battery life and battery capacity. The Droid RAZR MAXX has ridiculous battery life because it has a ridiculously large battery capacity -- 3300 mAh. But the HTC One X has a more traditionally sized 1800 mAh battery. (Though that's still on the larger side of traditional.) HTC's squeezed in a bit more capacity by sealing the battery inside the phone's body. That's a trade-off, of course, because you're not able to swap in a fresh, fully charged battery.

But we've found battery life on the Snapdragon S4 version of the One X to be even better than that of the Tegra 3 variety, which was fairly impressive in its own right.

Actually, forget our usual review-speak. Battery life on the AT&T One X/One XL is nothing short of incredible. How much of that is having the modem on the chipset, or how much of that is software tweaks, we really don't care. So long as the donuts taste good, you can make them however you like. And these donuts -- erm, battery life on this One X -- is nothing short of magical. We all talk about having a phone that will last "all day." In the AT&T HTC One X/One XL, we've found it.

My typical daily usage, like a lot of people, involves sitting at a desk all day, with a mighty fine Wifi connection. I'll have some 3G (cough, or AT&T's "4G" HSPA) use, but most of the day is spent connected to Wifi, using the phone in brief spurts. In that case, 15 hours of use comes easy. Even better is that I can leave the phone unplugged overnight and still have enough left over to get through breakfast. And that's what you see above. A full day's use, plus overnight standby time, which was about six hours or so.

But not everybody is connected to Wifi all day. So I turned it off for a day. Now, the strength of your HSPA cellular connection will also affect battery life. So if your phone's constantly searching for a signal, you're going to have a relatively short day. In my case, though, with a strong cell signal, battery life was just about equally impressive. Again, above, you see a full day's use plus overnight standby time with the phone unplugged, again, for about six hours.

I know folks like to pay particular attention the amount of time that the screen's on. But what goes on behind the scenes when the screen is turned off is as important as what's happening when the display is turned on. And in that respect, we've found standby time to be excellent.

As for battery life and LTE, well, not a whole lot's changed there. LTE data still chews through a battery quicker than traditional 3G data. That's life. And it's disappointing that AT&T hasn't included a simple LTE-off toggle switch, or even an option in the settings.

A lot of folks have asked about battery life when not in an LTE market, worried that the dormant radio might somehow drain power searching for an LTE signal. I don't live in an LTE market, and I haven't noticed one bit. (See the examples above.)

Coming back down to Earth - skimping on storage space


Oh, but those trade-offs. AT&T has opted to go with "only" 16 gigabytes of on-board storage on its One X. That, we believe, is a mistake. Presumably it was done for cost savings. But we still want and need as much local storage as we can get for photos, movies and music. It can't all be copied to and served from the cloud. And for as great as AT&T's One X is, 16GB of storage is a limiting factor that's going to turn away some potential buyers.

That's not to say that we wouldn't recommend the AT&T One X because it's got half the storage space of other versions of the same phone. It's still a great device. But that's a spec you need to be aware of, if on-board storage is a major concern for you.



The software

No real surprises here. The AT&T HTC One X is running the latest version of Android, dubbed Ice Cream Sandwich. It's got the Android 4.0.3 build, which is a tick off the most recent build, but that's not exactly keeping us up nights.

The One X also is running Sense 4, which is the name HTC gives to its custom software and user interface tweaks on top of Android. And you've read in our full review, we're pretty impressed with Sense 4.


But we are talking about a carrier-branded phone here. And that means AT&T has added its own apps, preloaded the home screens to its liking, and done a few other tweaks. As far as the AT&T-loaded applications go, you're looking at things like AT&T Navigator (aka Telenav), AT&T Ready2Go (which is a setup app), AT&T Address Book, Code Scanner, FamilyMap, Hot Spots and Live TV, myAT&T (account info) and the YP Mobile apps. A virgin phone, this is not. But because it's running Ice Cream Sandwich, you're able to disable and hide most of these apps.

Updates are handled through AT&T's servers as well, so the Software Update section of the settings menu is in a slightly different place.

Also worth noting is that we're not seeing any of the analytics tools that we've seen recently, whether it's the Tell HTC service, or Carrier IQ, which T-Mobile is using on the HTC One S. If there is any sort of diagnostics or analytics tool, it's out of sight.

The AT&T HTC One X cameras


As you've probably guessed, the AT&T HTC One X camera is the same as its One S (and Tegra 3 One S) cousins in that there's an 8MP rear shooter with flash, and a front-facing 1.3MP shooter. It's all controlled by a dedicated "ImageSense" processor. Shutter speed is a mere 0.7 seconds -- nearly instantaneous -- and you can snap still images while shooting video (up to 1080p). Plus, there are all the cool effects that we detailed previously.

Other odds and ends

A few other musings on the AT&T HTC One X:

  • Phone calls have been a little flaky in that at times they'll sound like you've pressed your ear too far into the phone, covering the speaker. Of course, that's not the case, and it's just AT&T's network being AT&T's network.
  • The rear speaker has served us just fine, though.
  • GPS has been quick to connect and works as it does on our other phones.
  • NFC and Wifi Direct are both on board and work as advertised.

The wrap-up

This is pretty simple. The AT&T HTC One X is one hell of a phone. We mostly knew that already, thanks to some serious time with the One X in its international GSM flavor and a Tegra 3 processor. Adding in LTE data and the incredible battery life with the Qualcomm Snapdragon S4 processor (never mind that it's powerful, too), and this is the phone to beat.

That said, we do understand that the 16GB of storage is a turn-off for some. We'd prefer to have seen 32GB, and easily would have accepted another $50 on the price of the subsidized phone (which is a respectable $199.99).

But the simple fact is that: When the HTC One X hits AT&T on May 6, it's the phone to get, hands-down. Beautiful display, great camera, and insane battery life. LTE's a sweetener. The question is, how long before the other manufacturers start nipping at HTC's heels?

AT&T HTC One X review


Wow, the HTC EVO LTE looks to be phone of the year if this is true: even bigger battery and MicroSD support. Can't say I'm not pissing my pants in excitement. Step up your game Samsung!

I would expect the One X to remain the phone of the year, since its sold world-wide and is still the better phone but the removable storage, but 32GB is way enough.

"That's not to say that we wouldn't recommend the AT&T One X because it's got half the storage space of other versions of the same phone"

I'd just like to say that this is actually wrong. The 32GBs actually have 2.6 times more storage. That's actually quite a big difference. How? if out of 16GB you only have 10, then out of 32 you should have 26. 26 is 2.6 times more than 10. If it were half it would be 20/10 but you get more than 2 and a half more usable space on the 32GB version. Sure, the flash chip is half but the usable space is even less than that.

AT&T/HTC needs to come out with a 32GB version. They're selling this thing for 199, why not have one for 299? I'd leave Sprint for this thing if it were 32GB, but as is I can't be bothered with a device that has almost less space than the smallest iphone.

Why would you leave Sprint for "this thing" when Sprint is about to release the same phone but WITH MICRO SD so you can add an ADDITIONAL 32GB of storage. Plus larger battery. Plus kickstand.

(BTW- your analysis of *free* storage space is spot-on)

Well it's more than just the phone, my wife and I could share a plan on AT&T and Sprint coverage at my work is pretty poor. I admit they're not crazy strong reasons.

But yeah I've decided for space reasons alone I'll just deal with the Evolte (shouldn't be on the phone at work anyway).

Well, there are plenty of differences in networks- speed, coverage, pricing, data restrictions, features, family plans. And those are all valid considerations. But your post made it sound like you wanted to leave just to get the HTC One X, when an even better phone is right around the corner on your existing network!

Because of speed. The EVO LTE is the better device, but the network is a huge part of the equation. For 95% of consumers, the EVO LTE will be a 3G device for at least half of their contract. Wimax still never made it to my city (which is only 20 miles outside of Orlando) 2 years after launching.

I already went through the 4G growing pains once with Sprint when I got the Evo 4G (and Evo 3D). I can't bring myself to wait for 4G again in the year 2012.

The majority of customers (me included) never even got WiMax, so we have nothing to lose, unfortunately. My main problem is that Sprint's 3G in my area is insanely slow now. Didn't used to be. But over the last year and a half, my average has plummeted to around 100kbs.

"and battery life (with LTE turned off anyway) is the best we've seen on an Android smartphone to date."

"There's no way to turn off LTE data if you'd prefer to save on battery."

Which is it? I'm confused. Are you just referring to LTE being off when you're on WiFi?

Pre-ordered mine from Radio Shack today for $49.99. Can't wait for it to get here!!

My Captivate will be relegated to a game machine for my son. :)


It was 49 Today. I had pre ordered from amazon, and they matched it. It just has to be a primary line upgrade.

Phil I'm confused:

LTE data is fast, and battery life (with LTE turned off anyway) is the best we've seen on an Android smartphone to date.


There's no way to turn off LTE data if you'd prefer to save on battery.

Can you turn it off or not, I'll get the unlocked Canadian version up here if I can turn LTE off

My guess is that he was in an area without LTE coverage, therefore he was able to enjoy the battery life of not having the LTE radio actually running,

Wow that picture of the beach/sunset is fantastic, atleast in window-shrunken version. The camera really seems to seal the deal for me. Curious is Samsung has anything in their SIII like this with the quick photo times, and picture while recording.

From theverge.com

"But the software buffoonery doesn't end there. In an effort to enforce Wi-Fi offloading, AT&T's "attwifi" Wi-Fi SSID can't be removed, so the phone will connect to the carrier's hotspots whenever Wi-Fi is turned on and you're in range. On a slower HSPA phone that might not be a big deal, but on the One X, it is: not only is AT&T LTE faster than its Wi-Fi hotspots (sometimes by an order of magnitude), but if you're walking around an urban area and passing by Starbucks or FedEx Office locations, your data service will keep dropping and reconnecting as you transition from cellular to Wi-Fi and back to cellular. If you're in the middle of browsing or listening to streaming radio, it's a pretty serious monkey wrench."

While that could be a work around, it is a hassle to have to turn it off and on and off and on. I know that I go from one "zone" to another all the time and if I was stuck with that limitation, it would be more than a little frustrating.

I hate it when carriers have to "inject" their politics and restrictions on expensive stuff we own.

True enough. Plus, some of those access points require you to agree to terms of service each time, which really means nothing gets done till you open the browser.

Well alot of people including myself leave wifi on at all times. That way you dont have to think about turning it off and on when your in range of your preferred wifi routers. It wouldn't be a problem if AT&T hotspot had good speeds. Connecting to at&t hotspots are like going to a edge connection

Seems like there's an easy enough workaround to that problem: disable automatic joining/notification of non-preferred networks.

Great review.. Always very detailed and straight to the goodness! I was wondering about the NFC.. I have mine pre-ordered already and hopefully get it friday (email says May 4th it will be delivered). Can you install google wallet or another payment option for it? Not even sure if there is an alternative to google wallet.. I know sprint as some exclusive deal with it and I have heard that the other us carriers have it blocked in some way.. Can you confirm that it doesn't work with the at&t one x?

Waiting impatiently for the HTC Evo One X (Evo 4G LTE)!!!!!!

Phil- two points in your summary are directly conflicting:

>"LTE data is fast, and battery life (with LTE turned off anyway) is the best we've seen..."

then you say

>"There's no way to turn off LTE data if you'd prefer to save on battery."

So which statement is correct?

I don't see where that quote is you are referring too but I suppose he's talking about being on wifi and not data...

Great review, Phil. I have one question that a lot of reviewers overlook:

How long does it take to fully charge the battery? (via wall outlet or computer)

I hope it's better than the 4-6 hours it takes for my Captivate.

I appreciate your info. My iPhone (3G) seemed to charge in half the time and was one of the few pluses of the iPhone. My Captivate seems to take as long to charge as it does to deplete from my usage. Time to upgrade!

I'll reserve judgment on what is the phone to beat until we see what Samsung's announcing this week. I bought into (literally) all the hype about how much better the screen on the One X is than the Galaxy Nexus, but sitting here comparing them side-by-side, SAMOLED remains the visual champ for my eyes. Blacks are inky vs LCD's grayish black, and the whites on the SAMOLED are a bit cooler, but more distinct. I suppose this is a matter of taste, both look great, but GN edges out for me.

I purchased the Euro HTC One X because there's no way I'd settle for 16gb no sdcard, and I suspect getting LTE would require new data-plan and lose me my grandfathered unlimited data. If anyone know better, please correct me on that.

If Sammy comes out with a SAMOLED hi-res device with otherwise similar specs to the One X any time soon, this One X is going back.

Dude, thank you SO much for the comment on screens. I recently bought the Galaxy Nexus (GSM) and was slightly disappointed when I started reading reviews raving about the One X's screen. One of them even said it blows away the Galaxy Nexus and I was starting to regret my purchase.

You just made me feel a whole lot better. Plus, we'll get Jellybean long before any of the skinned phones do.

Yes! I have been very impressed with what I've seen with the S4 so far. I can't wait to get rid of this BB Bold 9700 but I'm still waiting to see what Sammy has for us on Thursday before I make a decision on my first Android phone. I live in Toronto and we've had the One X available for a few weeks now. It's been tempting but I decided to hold off to see how the tegra3 and S4 compare. Now its just a matter of what Samsung does on Thursday and if they will have the Galaxy S3 released here in a reasonable time frame. I'm getting tired of waiting. The Snapgragon S4 will do just fine. No Tegra3, no problem.

Welcome! I'm going to get the EVO LTE, and it'll be MY 1st HTC Android... :D It'll also be my 4th Android phone... but you're choosing a winner!

With chips like these, I hope not-quite-ready for primetime, pointless 4-core phones don't show their face stateside for quite sometime.

the S4 shows what happens when you try to make a chip that is excellent for phones. The 4Core monsters are what happens when marketers and PC chip manufacturers try to do it.

9mb of usable memory. That is far from a top of the line phone. That is a joke. Come on, How the hell can you go and design a very impressive phone and leave out what I feel is the most important part, freaken memory. If you are going to leave out the sd-card then why do you cut the 32gb of internal memory down to only 9mb of usable memory? They ruined the phone. I don't care about all the so called cloud storage, that is bull shit. I was looking forward to this phone but you can be damn sure I will pass. The more you buy these pathetic specked out phones they will continue to make them. Don't buy.
Phil says he is buying one that is because he owns every phone that comes out, if he had to pick just one device I would gamble he would not pick the one with 9mb of usable memory. Just my Opinion.

The phone has the same amount of memory as most every other current, higher-end Android smart phone: 1GB.

I think you mean "storage"....

Not Necessarily. These days, when PC Makers and Smartphone manufacturers refer to "memory", they are talking about RAM (Which is short for Random Access Memory). That is a different beast than actual storage.

Not in computer science it isn't. Memory is RAM. Always has been.

Memory is volatile (temporary).

Storage is for non-volatile (non-temporary/"permanent") retention of data. We don't call hard drives "memory", we don't call flash drives "memory", we don't call DVDRW discs "memory". When you say your computer has 2GB of memory, it means RAM.

It is marketing crap that has contaminated the common speak because they think people are too stupid to understand the difference, and it is irritating. I can understand not wanting to use the word "RAM", but calling storage "memory" is just stupid. And you go to sites trying to get specs and it says only "2GB of memory", so now it is even MORE confusing- do they mean memory or storage?

I was going to say the same thing. I get about 12-15 hours on my galaxy note, but my screen time is closer to 4 hours. That's with wifi, bluetooth, gtalk, and data sync all on. If I'm just leaving my phone idle and just peep at the screen here and there, I can get over 24 hours too.

I have the international Version and I am getting around 22hr out of mine.. The key is you need to download Voltage Control from the Market (and u need to be rooted) and change the governor to interactive, and min speed to 340mhz and maz to 1500mhz and this is on the 1.29 Firmware

The battery life doesn't really seem any better than what I get on my stock International version. I'm not running voltage control, or any of that stuff, but get to 24 hours on a charge if I'm only actually using the phone for 2-3 of those hours (screen on). I personally don't think the extra speed of the LTE radio is worth the battery drain, and not having to deal with AT&T's crapware and limited memory is a big plus. BUT, it did cost a lot more than a subsidized version. However, not so much if you compare to the non-subisidized cost. In any event, I think they are both good devices and am glad HTC has upped their game with these.

I really want this phone but I hate the small internal storage/lack of SD slot. For my immediate needs 9-10 gigs might be enough for my usage but I worry a lot about the long term. A couple of games with good graphics and its done. I have a Transformer prime so it might stand in as the more likely gaming usage on something like a plane flight but I hate to support these sorts of terrible short sighted decisions.

I have to agree with you there. The lack of expandable storage is a deal breaker for a lot of people. If you are going to withhold an expandable mirco SD slot then at least make the phone available in 32 and 64 gigs like the iPhone is. Like you said, a couple movies, a game or two and a music playlist for those long drives and it's full. Seems like such a waste...

I picked up a Nexus S and thought I'd be ok with only 16GB (14 usable) but man, I ran out. Nothing like finding out you ran out of space when you were trying to take a picture of your kid and it told you it couldn't save the picture due to no more space.

10GB is a joke.

Less than 10 GB of actual storage IS a dealbreaker, especially on a phone from AT&T where the data caps or throttling means you can't rely too much on cloud media streaming.

It does seem odd that AT&T would make what appears to be such a critical mistake. Limiting a "superphone" that costs over $500 to just 10GB of storage is kinda crazy when you consider they could have added another 16GB of free space for something like $5! Maybe they will realize their mistake and request HTC to make an increased capacity version?

I myself see it as a huge upgrade in storage. I have been using an HTC Aria with 185mb of usable storage for the past two years. Now that is a joke. I would like to have more storage sure, but I know how to make do with much less.

I am going to avoid LTE phones as long as I can. With At&t demanding small storage capacity(So you have to use cloud storage) I find At&t 3G so fast and so prevalent in the Northeast. I can't think of any reason I would need speeds greater then my home Broadband, other then to have a rogue app once a month using up my unthrottled 3Gig's and leaving me with throttled data.

I wish there were more folks willing to forgo contracts just so they have the option of leaving the Carrier. Looking forward to Thursday's S3. (After the disappointment I'll opt for the GN)

The bad:
Ugly box
Ugly design
Too shame to show it to any girlfriend
Impossible to beat apple for this

The good:


Exactly what would make it "pretty", then? Flowers? Polka dots? It is a phone, not a fashion statement. It looks like most modern phones- a slab of glass with mimimal bezel on a thin, rectangular body. Big whoop.

Who cares about a box?
Who cares about Apple?

I don't understand your "points".

Forget him, he's trolling.

No sentient being could hold this phone in their hands and pronounce it Ugly.

Maybe an iphone fanboy could, but again, we are limiting this discussion to intelligent life forms.

The international version of it will, I had a Unlimited Data PAYG SIM in it for a few days whilst I was waiting for my replacement Micro-SIM to be activated.

Between Android Central, AnandTech, Engadget, and DroidLife, I'm convinced that my next phone will be the One X. It's going to take a lot on Thursday to convince me to go with the Galaxy S3, especially since my Captivate continues to act like shit.

You forgot Puerto Rico on the list of AT&T LTE locations.

As far as battery life, I do hope you were doing a whole lot of something when the screen was off... Because two hours of actual display-on usage is pretty darn poor.

If you have a ton of accounts set to sync/poll then I guess it's a different story, but on my EVO 3D I routinely get 4-5 hours of screen on time while on Wifi, 3-4 on 3G even with a poor signal; and I know the EVO 3D isn't even amongst the most efficient phones out there. I also get that usage regardless of idle time since I don't have much stuff syncing in the background (gmail, weather, one imap account set to 4 hours, FB, that's about it). I can go for just 8 hours or 20, but I'll get 4-5 of actual use regardless.

Hopefully you're right and battery life is impressive and you've just chosen a poor way of characterizing it, you should seriously consider standardizing some kind of battery life test you can replicate across phones... It'd be a much more useful metric than these vague comments based on a personal usage pattern that no one's familiar with, I don't know why there's only one site on the net that does this properly.

Off to read Anandtech's review now, I'll probably start by the battery testing section... :p Edit: Their testing redeems your comments regarding battery life, tho your method to showcasing it is still pretty poor (and you either have a massive wakelock situation going on with an app or a ton of stuff set to background sync).

He forgot a lot of places. Wash DC has had the LTE network since the launch in Nov, I had gotten the SGS2 Skyrocket and was getting LTE speeds of over 30mpbs.

Here are more test done by Slash gear http://www.slashgear.com/htc-one-x-review-att-01225390/


"The Tegra 3 model has significantly stronger CPU performance, unsurprisingly, almost double what the S4 can manage; however, the Snapdragon delivers roughly twice the memory I/O. That’s in no small part down to its dual memory channels, and means data read/write is faster."


"With the display set to be permanently on, along with GPS, and with mixed use of WiFi and cellular data, playing videos and browsing the internet, both versions of the One X managed to run for over eight hours with 26-percent power left. Bear in mind this is an extreme case: with more typical – though still heavy – use, we went for nearly a full day on a single charge."

Goodbye Sprint, hello AT&T.

This phone is soo damn gorgeous!!! Gonna hit up bestbuy tomorrow and preorder it!

You have fun with no SD Card and smaller battery. I'll be enjoying my Evp LTE in about a month or so anyway. :-)

Sounds like a personally problem.

I said the same thing when I jumped ship to Sprint (was on Tmobile) for the Evo 4G, I told myself I would never join Sprint. Than I heard about cheap data, wimaxx and great CDMA tech and well, I was dupped. 1 out 3 aint bad right? LMFAOOO.

Goodbye Sprint, it's been kinda good.

1. 16GB is MORE than enough for ME. Plus an extra 25GB from Dropbox and my 5GB Google Drive sums up your mute #1 point.

2. Read the reviews all over the web, the One X gets GREAT battery life. Nobody is complaining but YOU and you don't even have a One X. Mute statement #2.

3. Enjoy your Evo 4G LT... wait, you don't have LTE yet. NOBODY has it on Sprint yet, NOT EVEN SPRINT THEMSELVES. I fell for that BS when I bought my Evo 4G and I still don't have WiMaxx in my city. LTE is HERE in my city and it's pretty damn fast too, blowing away anything Sprint can do on WiMaxx, and what they're able to do on there assumed LTE network. Mute statement #3.

Your 0-3 bro.

Preorders for the EVO LTE start this month (5/7 to be exact). I will def be getting that!! Sprint's LTE network, they say, will be just as big as Verizon's by the end of 2013. I am really hoping they stick to that and it is an extreamly rapid rollout. I guess only time will tell.

Why are half of these comments about the EVO LTE? Who is even on Sprint's horrible network? A shame that Sprint gets a pretty good phone. I can't see anyone wanting to be on that horrible network. AT&T's network is superior in so many ways. What's funny is AT&T's 2G (EDGE) can compete against Sprint's EVDO. Anyone who buys a "4G" device on Sprint will more than likely be limited to 3G only as they are WAY behind in the LTE catch up game.

So glad I'm on a GSM carrier.

What's GSM got to do with it? Verizon's got an even better network than AT&T and they're CDMA...

I wish we had Verizon where I live (Puerto Rico), they charge an eye but clearly invest the most on their network, and right now they have better data plans with the double data promo.

For my part, I'm on Sprint even tho AT&T already has LTE here because I had several horrible CS experiences with AT&T, plus Sprint's unlimited & cheaper ($64/mo. with my student discount, including the premium data charge). AT&T would probably not be too bad now that they've raised bandwith caps slightly (I'm usually right around 2GB every month) but ehh... Sprint swayed me to stick around with the superior EVO 4G LTE.

If their LTE expansion turns into a disaster thru 2012 then I'll consider switching, and so will most of their customers I think. At that point AT&T's and VZW's LTE should be in wide deployment... Sprint's too if they stick to the roadmap, we'll see.

I think he's referring to the fact that GSM is a lot faster then CDMA, so even when your on GSM 2G you still get pretty decent speeds for 2G (300Kbps) compared to the 50Kbps on CDMA.

Also LTE GSM phones will have better battery life then the CDMA LTE phones, this is because the CDMA LTE phones have to constantly keep the CDMA on, where as LTE is backwards compatible with HSPA, so on a GSM phone it can be turned off.

1) Because it is the same phone but not as great as the Evo LTE
2) There are many, many, many, millions of people on the Sprint network
3) You are right only in that Sprint's current 3G network is very slow in many areas (mine included).
4) Has nothing to do with GSM.

Someone butt hurt that AT&T is the butt of the jokes?

Anyway, yes HSPA is faster than Sprint 3G and Verizon 3G...but I don't know who these people are overblowing sprint network speed. Just ran a speed test 1.12Mbps down on 3G.

Plus I also have an Evo that got 8Mbps consistently on Wimax with peaks of around 12Mbps.

Oh and whose on Sprints "horrible network?" 55 Million.

Enjoy your unnecessarily high bill and limited data.

This and the Galaxy S3 would probably be the only phones that would get me to give up my GNex. However, I just can't give up my unlimited data on Verizon.

Nice phone and review!

Can't wait for Sprint's version (Evo 4G LTE) this is a pretty bada** phone with some really impressive features. Even though im not an AT&T customer anymore you can bet come May 6th ill be in one of their stores playing with this phone!

Great review, but I have one question. What the hell are those frogs doing in that picture????!?!?! I'm just saying...

Only three more days until I have this in my hands, and can't wait. I haven't been this excited about a phone launch since the iPhone 4.

Great review.

Author should add more information about the ability to beam/clone the phone screen to the TV using wireless media link HD. This is the first!

Good review, but the 32 gig tegra 3 will put out similar battery levels with the use you are showing, you have barely used it at 1 hour 20
If I use mine purely as a phone with email push you can get 48 hrs on time.

I've got the Telstra version of the equivalent S4 AT&T HTC One XL but it comes with 32gb over here! so its even better than the original One X! :)
