Sony Xperia X Performance review: 80% of a great phone

The quick take

The Sony Xperia X Performance is a good phone, but it not only fails to justify its $150 premium over its cheaper counterpart, it also falls down as a flagship, too. Too few improvements over the Z5 series, and some frustrating screen responsiveness issues, have us asking how, after so long, Sony still can't get it right.

The Good

  • Great performance in apps and games
  • Nice daylight photo capabilities
  • Excellent stereo sound output
  • Waterproof metal chassis is one hand-friendly

The Bad

  • Stupefying screen responsiveness issues
  • Slow camera startup and occasional shutter stutter
  • Too similar to the Z5
  • Can't justify its $150 price increase over Xperia X

Fighting to justify a price

Sony Xperia X Performance Full review

Sony's had an interesting few years in the mobile space. Since 2013, the company released a new Z-series product every eight months or so, iterating on what has become a relatively safe, austere design ethic. When the series arrived at its fifth version (the Japan-only Z4 notwithstanding) in 2015, it became apparent there wasn't much innovation left to extract from, as the company claimed, "the best of Sony."

That's why, when the Xperia X and its Performance counterpart were unveiled at Mobile World Congress earlier this year, I was at once let down and cautiously optimistic about Sony's commitment to improvement. Let down because at first glance the new series resembled its predecessors in too many ways; optimistic because Sony claimed that it was breaking ties with its past.

The reality is somewhere in the middle: while the Xperia X, and its X Performance counterpart, are in some ways marked improvements in Sony's mobile narrative, they are also regressions in a couple important ways. And when the more expensive of the two arrives at a price point equivalent to some of the best products on the market, its existence becomes harder to justify.

About this review

I (Daniel Bader) am writing this review after using the Canadian model of the Sony Xperia X Performance (F8131) for two weeks in the Greater Toronto area. I used the phone primarily on Bell's LTE network, but popped in my personal Rogers SIM card for a time.

The device ran Android 6.0.1 on Build number 35.0.A.1.227 for the entirety, with a (disappointing) April 1, 2016 security patch.

  • 5.0-inch Full HD
  • IPS LCD Display
  • 1920x1080 resolution (441ppi)
  • 23MP, ƒ/2.0 lens
  • 13MP front camera
  • 2700 mAh capacity
  • Quick Charge 2.0
  • Qualcomm Snapdragon 820 processor
  • Dual-core 2.2GHz, Dual-core 1.6Ghz
  • 3GB RAM
  • 32GB internal storage
  • microSD slot

Xperia X Performance

Same difference

Sony Xperia X Performance Hardware

Last year, when Sony replaced its so-called OmniBalance power button with a flat, sunken key that doubled as a fingerprint sensor, there was a palpable sense of rightness in the decision. That the Xperia X Performance maintains that legacy is no surprise, but Sony's decision to keep all but a few elements of the Z series in tact is — and disappointing.

(A quick note: the U.S. version of the Sony Xperia X Performance doesn't include a fingerprint sensor in the power button, for reasons both confusing to us and irrelevant to users who miss out on one of the phone's best features.)

Compact though it is — the metallic chassis more than resembles the Xperia Z5 Compact — the 5-inch display approaches the edges on the vertical side but leaves plenty of room on the horizontal. Thankfully, Sony decided to use the area on top of the 2700 mAh to expand the cavities in both front-facing speakers, resulting in some of the best external sound I've heard on a smartphone outside of HTC's products.

The right side reinforces Sony's "if it ain't broke" mentality, recalling every Z-series product with the centered power button above an elongated volume rocker and dual-step camera shutter. I suppose I should be grateful for the camera shutter, but as you'll see later, its efficacy is marred by software that cares little for cooperating.

While the phone's IPS panel is great, the phone's touch sensor is not. In fact, it's the X Performance's biggest fault.

And while the phone's frame is metal, as is the back, whose hairline brushed texture differentiates it from the staid aluminum of the Xperia X, the sides are a smooth plastic, which elegantly meet the curved glass of the 1080p screen.

I concur with Mr. Dobie in saying that I don't begrudge Sony sticking to a 1920x1080 pixel panel for the X series; it is not only one of the best I've seen on a smartphone, but at 441ppi it is sufficiently sharp to meet even the most demanding of critics. Moreover, the screen gets bright — really bright — which is fantastic for outdoor visibility.

Xperia X Performance

But here's the thing: while the IPS LCD panel is great, the phone's touch sensor is not. In fact, it's the X Performance's biggest fault. When I began using the phone, I tapped out a few messages to some friends and discovered the screen couldn't keep up. I changed keyboards, from the default SwiftKey to Google Keyboard, with identical results. I descended pages in Chrome, realizing the phone didn't always register my light taps to stop scrolling. I did the same for Twitter, with identical results.

In app after app, I discovered the X Performance failed to register light taps. I went back to the Xperia X and noticed a similar trend. I asked Andrew Martonik, who received the X Performance a week after me, who corroborated my findings.

Now, touch sensitivity is a, well, sensitive topic. Some people mash their keyboards; others very deliberately tap to stop a scrolling web page. Those people should be fine with the X Performance, but this is an issue I haven't experienced so overtly since the poor touch performance on the Nexus One back in 2010. For the way I use my phone, the X Performance quickly became an exercise in frustration. While I found more success switching to gliding, that I couldn't confidently type consistently marred the experience of using the Xperia X Performance. What's unclear is whether the X Performance could avert this disaster on a larger scale with a software update, or if the touch sensor is inherently flawed. (Sony has been mute on the topic so far.)

It's also possible that I am being overly, well, sensitive to this whole thing and that its screen sensitivity will go unnoticed by Sony's customers — but I'm willing to bet it won't.

Around back, the X Performance's camera neither protrudes nor draws attention to itself, which is a nice change of pace from the rest of the big players in the industry, but the single LED flash is disappointingly perfunctory. More on the camera below.

The specs contained inside is where the X Performance is supposed to differentiate itself. With a quad-core Snapdragon 820 — currently Qualcomm's fastest chip, and the same one found in the Samsung Galaxy S7, LG G5, and HTC 10 — the Performance has ample room to breathe. In fact, as Alex noted in his review of the Xperia X, even the much slower Snapdragon 650 is sufficiently capable of powering Android 6.0 with a 1080p display.

Xperia X Performance

So why covet the more powerful chip? While apps and games certainly load faster and perform better, much of the difference can be seen in the speed at which the camera app loads and takes pictures. Sony still has a long way to go to compete with Samsung and HTC when it comes to the camera loading times — the speed at which you go from black screen to shutter — but the X Performance is notably faster than the X in this regard. The Snapdragon 820 also has a best-in-class image signal processor that improves overall photo quality by reducing noise, especially in low light, and anticipating hand shake to offset motion blur. Unfortunately, without optical image stabilization, Sony's excellent 23MP sensor is still subject to the whims of physics, but the X Performance takes great photos at least some of the time.

So subtle

Xperia X Performance Software

It's clear that, like many other OEMs, Sony is moving away from software differentiation in favor of a simplified launcher and Material Design flourishes in its apps.

But Sony has not taken hints from the likes of HTC in reducing the number of apps it pre-installs on its devices. To wit, the Xperia X Performance arrives replete with (admittedly well-designed) takes on the gallery, video player, music player, email client, news aggregator, weather app, fitness app, sketching app, movie maker, and Shazam clone. (A few like to pop up promotional notifications as well.) In all, aside from the essentials like the phone and contacts app, there were 14 Sony-built apps preloaded on the X Performance, and a couple others, like Amazon Shopping and AVG Protection antivirus, that were tacked on for additional revenue.

Defying appearances of a lightweight experience, Sony's version of Android occupies nearly 12GB of the phone's 32GB of internal storage

I can't really begrudge Sony for wanting to outfit its customers with the best experiences, but there is just too much in the way of superfluous and unnecessary software here for my liking. Apps like Movie Creator and Sketch are inherently not well suited for a 5-inch canvas, and should have stayed on the Play Store as opt-in experiences.

Defying appearances of a lightweight experience, Sony's version of Android occupies nearly 12GB of the phone's 32GB of internal storage, a gross misuse of important user resources. Some of these assets can be found in the form of themes, four of which are included on the phone, with many more available on Sony's haphazardly stocked and of-dubious-quality Xperia Theme store.

The company's launcher has stolen one of the better features from the iPhone in the ability to swipe down on an unused portion of the homescreen to quickly search for and open apps. While Sony does use this as an opportunity to suggest likely-sponsored apps, I found it an effortless and intuitive way to quickly bypass the folder/app drawer dichotomy. Elsewhere, the multitasking menu, notification shade, and quick settings are all reminiscent of stock Android Marshmallow, which I dare say is a good call.

Xperia X Performance

As it tends to, Sony's bundled a confusing array of audio options that are thankfully not necessary to enjoy the phone's excellent aural output, but present for those who want to tweak. A feature taken from the company's new Walkman line, DSEE HX, upconverts music to "near Hi-Res Audio quality" by interpreting in real time and filling in the frequency gaps in most modern compressed audio streams. Another, ClearAudio+, automatically equalizes and normalizes music played from either the headphone jack or front-facing speakers. I found that neither setting dramatically improved the quality of a typical 320kbps Spotify stream.

Similarly, Sony's outfitted the X Performance with a vast array of display settings, including its mainstay X-Reality for mobile algorithms that improve the quality of photos and videos when viewed or played through its first-party apps. These are, as above, subtle changes that most people either won't notice or take the time to appreciate. They'll just hear great audio and view vivid images.

Xperia X Performance

Here's what I think: If Sony really wanted to use the X line to split from the deleterious abundance of options in its Z series, it should have merely incorporated these algorithms into the core operating system and removed the user from the equation altogether. As it stands, the X line is shaping up to be just as bloated as its forebears, which will (in addition to its insane price) harm its mass appeal. Samsung is a good example of a company that learned its lesson between generations by explicitly simplifying its software, emphasizing only those features it truly believes users will want to both download, and use.

Xperia X Performance

Sharp, at times

Sony Xperia X Performance Cameras

If you want the best camera on an Android phone, especially one in the $500+ range, look elsewhere. While the quality is marginably improved over the regular Xperia X, thanks to differences in the image signal processing between the Snapdragon 650 and 820, you're getting pretty close to the same experience.

As with much of the X Performance, the camera experience is nearly great but is marred by a couple of glaring issues.

As in years past, the 23MP Exmor RS sensor is of high quality, but fails to impress in low light situations. In sunlight, though, I was able to take some pretty great photos, with sharp, fast focus and ample detail. In low light, however, the lack of optical image stabilization forces Sony's camera app to raise the light sensitivity (ISO) to undesirable levels in order to keep shutter speed apace with its subjects.

Let's put this into real-world terms: I attended a wedding this past weekend, and used the Xperia X Performance as my primary camera. Since it was at a botanical garden, I was able to snap some lovely nature photos, and some great portraits, all of which came out superbly thanks to Sony's relatively intelligent Superior Auto mode. But once we went indoors and the lights dimmed, the X Performance balked at any attempt I made to capture even the slowest-moving of humans, maxing its shutter at a woeful 1/8 despite ratcheting the ISO to above 2000.

While optical image stabilization doesn't solve for fast-moving subjects, it does account for hand shake, and usually leads to better photos in general. Sony's stubborn refusal to outfit even its flagship products with such a module borders on idiocy at this point, as practically every other OEM, from Samsung to HTC to LG, OnePlus and Huawei, have figured this out (the Nexus 6P being the one major exception).

Xperia X Performance

As with much of the X Performance, the camera experience is nearly great, but, photo quality aside, is marred by a couple of glaring issues. The camera app doesn't load quickly enough, and the shutter often stumbles on its first capture, which is usually of the most critical subject. And mirroring its predecessors, the app's manual mode is woefully understocked, with no ability to set shutter speed or focus. For a phone that wants to sell itself on the efficacy of its camera experience, it stumbles far too often.

One big change from the Z5 series is the 13MP front-facing camera, which is indeed one of the better sensors I've tried. It's also paired with a fairly wide f2.0 lens that meets all of the important criteria for social engagements: quick focus; room for more than two people without stretching; and smile shutter.

Xperia X Performance

Good, not great

Xperia X Performance Battery life

With a slightly larger 2700 mAh cell than its X counterpart, the X Performance offers merely average battery life. After using the phone as my daily driver for two weeks, I would end some days with upwards of 30% left in the tank, while on others I would contend with having to charge by 3 p.m. The Snapdragon 820 seems to be more efficient than the 810 found in the Z5, but I also think that phone's 2900 mAh was probably the right size, and I would have taken a slightly thicker chassis to benefit from an extra 10% of battery capacity.

Thankfully, the phone supports Qualcomm's Quick Charge 2.0 standard, which promises to charge it from dead to full in under 90 minutes. That said, some sort of fast charging support is table stakes for phones half this price. You'd also think that including a quick charger in the box would be table stakes ... but the Canadian model doesn't have one (the U.S. model does, though.)

Xperia X Performance

The Bottom Line

Should you buy the Sony Xperia X Performance? Probably not

Let's take a look at what we have. A phone with at least one critical flaw that could possibly be solved with a software update. A phone that, were it $200 cheaper, would still have trouble standing out amidst a sea of affordable and compelling Android devices. A phone that misses its opportunity to really capitalize on Sony's glowing reputation for making the industry's best phone camera sensors. A phone that insists on offering the same number of vexing and acronym-heavy audiovisual features as its predecessors.

When I look at the X Performance, I don't see a series that breaks away from its Z predecessor. I see evidence of a company that knows how to make 80% of a great smartphone and no idea where the other 20% is hiding.

Where to buy the Sony Xperia X Performance

You can buy the Sony Xperia X Performance from several retailers online in the U.S., as well as in Canada.

  • In US $700 unlocked for this or $769 for S7 edge unlocked. Think S7 edge beats out even though slightly expensive. Posted via the Android Central App
  • I'd say the comparison would be to the GS7, since we're talking about a 5-inch screen here.
  • No comparison still Galaxy S7 Edge Titanium

    Sony Xperia X Performance Performance Review
  • I think Sony should stick to making TV's and blank DVD's. Areas in which they can't seem to go wrong. With their phones I always get the idea they've been drummed up in a lunch hour by the work experience kid.... Posted via the Android Central App
  • The Xperia Z Series were solid devices all-around (with an average to good camera), though Sony didn't know how to properly sell them. The X Performance, aside from being overly overpriced, have too many misses to be considered a solid performer.
  • Agree. The Xperia Z3 was a near perfect device for me at the time. Battery life was ridiculously good. I don't understand what Sony is doing these days. Its like they hear the criticism and are hell bent on doing what they want anyway. I can no longer root for them to succeed with these types of practices. One picture at a time--LG V10
  • I feel the exact same way! I loved my Z3 but got jealous when I saw that other phones had better cameras, so I moved on. The Z3 always got attention from people because of its looks, and people were surprised that Sony even made phones. But for some reason Sony just can't, or won't, pull their heads out of their butts and fix what needs to be fixed.
  • I totally agree. The Z3 is the best phone I've ever owned, and I owned the original Z too and liked that. But Sony hasn't released a phone since that has made me want to upgrade, so I will probably somewhat reluctantly be moving away from them in future. Posted via the Android Central App
  • The only problem with the Z series were the sh*t OIS-less cameras. Yet Sony, stubborn as always, instead of addressing that and producing what the S7 is 2 years ago, simply refused to listen. Now you have the X series with the same sh*tty cameras but more flaws to go alongside it. Posted via the Android Central App
  • Their TV's are **** these days too. Like phones, Samsung & LG offer much better TV's for less money.
  • Has Sony made any statements whatsoever as to why the US model does not have a fingerprint reader? Really makes no sense unless there are patent issues in the US or something.
  • I was wondering the same thing. They have some explaining to do. But my guess is they know they won't sell many in the US (cause they don't put on carriers), so they want a bigger profit margin on the phone in the US. That's probably why. Corporate greed honestly. Posted via the Android Central App
  • If I had to guess, I'd say that whichever company they licensed their fingerprint sensor tech from wanted higher royalties on NA sales than Sony was comfortable paying, since Sony knows damn well that they're not going to sell many of these outside of Japan and Europe.
  • They said it was a business decision (cost savings I guess).
    At any rate, after that they announced the defocus on the US market (alongside third world countries like India and Brasil) so it shouldn't matter anyway going forward. Posted via the Android Central App
  • Wait, I thought the sensor is already there? Just disabled for some reason.
  • The sensor might be physically present on the phone, but you have to pay a license fee to whichever company supplies the tech in order to use it. The cost for licensing probably wasn't acceptable to Sony, especially if they weren't all that optimistic for how the device would sell in the U.S. If I'm not mistaken, they did they same exact thing for the Z5 series last year (no FS in the U.S.).
  • This review was hilarious in how brutally honest it was. Good job Daniel. I sold my great Z3 because the camera wasn't as consistent as I'd have wanted. I held a Z5 Compact recent and impressed at the design. I had a friend who wanted to sell me a Z5 and i passed because the camera was still not up to snuff. Love the X series design, but it looks like Sony wo t get money for a phone until they learn how to find that missing 20% you mentioned. Posted via Moto Maxx
  • They have a recognizable design, I'll give them that. But it's time to change it, it looks sooooooo dated! Posted via the Android Central App
  • Keeping my fingers crossed that Sony will (eventually) get their **** together...
  • I was going to get the regular X for my girlfriend because she loves her Z3 but T-Mobile abandoned the software updates. Its a beautiful phone. However no finger print scanner on X in the US and now touch screen issues?! Yeah, its a shame. The X would have been the 2nd best 1 handed phone on the market in US if not for those 2 things. (2nd to S7 no edge). Posted via the Android Central App
  • And Sony STILL doesn't get it. I wonder if the ones running Sony Mobile are even remotely interested in sales now. And we still have no OIS on the main camera...
  • One of my biggest gripes about my Z5P- Great phone other than that. Not surprised they still havent stuffed it in there.
  • It's pretty bad when there's been a two year gap between the Z2 and X Performance and there's still barely any difference. IMO, Sony hit it's peak with the Z3 but after that, I think they just stopped caring. Posted via the Android Central App
  • The Z3 was one of the best Android devices ever, but they have done nothing to address the few issues that that phone had, and they've managed to get worse in other areas. Posted via the Android Central App
  • Sony's design doesn't go well with 2.5D glass.
  • Agree. Xperia has always been about clean lines, not curves. Posted via the Android Central App
  • I actually liked the earlier Z series, but this thing looks like a pig,
    My brother has a z3, still a cool phone imo, it's a total fail when your new device is less good than the preceeding model.
  • This is a bummer. Seriously.
  • So drop price $200-$300 and fix everything with custom rom?
  • Dear Sony.......... that's all I got. One picture at a time--LG V10
  • It's unfortunate really that they seem to just blatantly refuse to address what's needed to be fixed. Oh well, there's plenty of better options out there for a lower price. I do like the Z5 though and it performs well.
    I don't see myself buying another Sony product going forward however. Posted via Xperia Z5
  • I don't know where to go now when I get an itch to move on from by Z3. I'd guess the Z5, but a $300 upgrade for a different processor doesn't do it for me. Makes me sad, as I love sony. I have their tablet, and I put aside my M8 for the Z3 on a great deal. Really wanted them to make something nice this time.
  • The one major feature on the Z5 that I particularly like over the Z3 is the flapless USB port. But like you say, does the price premium justify that? Also the speaker slits on the Z5 tend to trap dirt and lint, and you won't get the battery life you're used to with the Z3. Posted via Xperia Z5
  • This is a "mid-range" phone, and they are charging top tier flagship prices for this. Not worth it to pick this, over the OnePlus 3, unless you can't handle the size of the OnePlus. At the $700 price point, get the S7.
  • Agreed. Posted via the Android Central App
  • this is not a mid range phone Posted via the Android Central App
  • This has to be the worst run mobile division in the industry. Posted via the Android Central App
  • agreed
  • This review could have been for the Z5 Premium! Exactly the same issues it seems. Disappointing, as it seems Sony are just throwing money away without making any significant improvements to the quality of the software on board. Posted via the Android Central App
  • Fix your fatal error message. thanks.
  • I feel like you guys are forgetting the biggest actual selling point of Xperia phones - though not an advertised one - PlayStation Remote Play. I know a few different non-android users who've almost bought an Xperia phone just because of this feature alone.
  • Yeah but not everyone has a play station , or more importantly buys an expensive smart phone to interface with it.
  • What are table stakes. Not an expression I have ever heard.
  • I think it's a poker reference? Basically means the minimum level you need to compete. Posted via the Android Central App
  • After the Z3 I was highly interested in this phone but I'm disappointed with the showing. No fingerprint alone makes it a no go.
  • There is a fingerprint sensor if you don't buy the US edition. All other variants have the fingerprint sensor.
  • RiP Sony Smart phones... one of the final nails in their coffin.
  • How could they release a "Performance" version that has only 3 gb RAM, no OIS, and a 2700mah battery without losing their jobs over it? It is almost as if they are trying to be irrelevant.
  • OIS is inferior to Xperia digital stabilization, check out this video: This X Performance is a filler flagship, not meant to sell a lot. The real flagship is coming at IFA this October, wait for that.
  • What about photos? I don't think DIS really works for photos, especially when you have to utilize a slower shutter speed. Posted via the Android Central App
  • try harder Posted via the Android Central App
  • Was Xperia z3 user for 18 months, and gave 6 months opportunity to convince me with phone worth upgrade and they failed, I when and got the S7 edge In my basement in Senegal
  • So this phone is pretty much what the other Sony phones were. Great, but overpriced. Posted via the Android Central App
  • Can't even pay 400$for that garbage Posted via the Android Central App
  • One aside with Optical Image Stabilisation - whilst it may be great for photography it has disadvantages in videography since the OIS module can't cope with small vibrations and the moving image gets very very ugly and unusable. Sony's Digital Image Stabilisation continues to impress me, now if only they could marry that with a surround mic array with optional rear noise cancellation I would buy their next smartphone. I find it odd that I can film 60fps for 3 hours non-stop on a Microsoft Lumia but Xperias crap out with overheating after about 30 minutes. That is another major flaw Sony need to get around to fixing if they want to capture the videography market.
  • That's because Sony has better phone.
  • Best phone by Sony in years. At $688 at our shop they be gone fast. Sold 145 units this week alone. Sony is making a Dennis quaid kind of comeback for real.
  • I like the review, compared to some other review I read on this phone this one seems unbaised and brings out some nice points. I would like to see an update on this review though because most negatives pointed out have been already fixed by Sony. E.g: screen responsiveness issues was fixed via an update about 2-3 months ago, also I was tired of waiting for the android N update here in Canada so I asked a friend to flash the original N from europe and the experience it's so much better now!! I still would had preferred an XZ though but at the same time I don't feel as i'm missing much. Finally, I would like to point out that the changelog for the upcoming 7.1.1 update include "faster camera startup" thus partly eliminating another negative point from the review! Sony did not do an excellent job with this phone, I too was disappointed in the beginning, but their mistakes were mostly all software based and after having installed Nougat on my x performance, it feels like sony has redeemed itself and it now feels as a proper flagship again. The only remaining Sony stupidity left out in this phone is that 4K recording was not added back, not that I care but for a phone that has the same processor as the xz, it makes no sense for it not to be there. Regardless, I believe the x performance deserves a bit better than that now, especially with the new Nougat software. Even their software support was pretty speedy which is nice!
  • The writer should consider updating his review as many of the negative listed had been fixed already. Screen touch sensitive issue was fixed about 2 and a half months ago and now with nougat the performance feels like a proper flagship and its camera has improved manual controls. The upcoming 7.1.1 changelog also promises faster camera startup times, hence taking care another negative listed here. The x performance might had a rocky start but sony seems to have reedamed itself and have put good effort in fixing its mistakes. Anyways, I believe this review should be updated with the Nougat experience (once it's officially out by canadian carriers next month).
