Introduction
There's a shift of command in the house of Xperia. The Sony Xperia X and its two siblings are taking over from the Xperia Z. A dynasty has come to an end. We hear the C and M families are being put out to pasture as well, soon it will be all X top to bottom.
Sony Xperia X review
So, what's the new face of Sony like? The Xperia X, which will likely form the backbone of the new lineup, persists with the angular aesthetics that debuted with the original Xperia Z back in 2013. It has a metal back, but no more waterproofing (that's exclusive to the Xperia X Performance). Sony's trademark sonic experience however lives on with the on-board stereo speakers and High-Res audio. Another Sony staple, the camera, is more than robust but has an uncomfortable question to answer.

We need to re-draw the Xperia family tree. If we agree that the Xperia X Performance replaces the Z5, then which one is X's predecessor? We think it's the Xperia M5.
Here's the deal: 5" 1080p screen, 13MP selfie camera, 21.2MP main camera with 4K video, IP68 rating. That's the Xperia M5. The Xperia X throws in a metal back and stereo speakers, but it loses 4K and IP68. It's an awkward trade-off to make against last year's midranger.
Sony says that its secret sauce makes the Xperia X more than just a midrange handset and we're sure Sony fans would agree. So, if you want to experience this phone with your heart first - feel free. Starting on the next page, the hard facts and reason are back in the conversation.
Unboxing the Sony Xperia X
The box appears all white, but as soon as you remove the top you are greeted with a burst of color - a promise of a multitude of hues to come from the X-Reality display. There's also the huge new logo of the re-branded X-line.
The box itself doesn't hold much - the phone, the manuals, a charger and a cable. We didn't get a headset; maybe that's just the review unit as there's an empty spot in the box, big enough to hold a headset.

It's important to note that while the Xperia X supports Quick Charging, the in-box unit puts out 1.5A at 5V. That's not very powerful, even for a non-quick charger. Packaging in the US is different, though, and includes a Sony UCH10 Quick Charger, which offers Quick Charge 2.0.
We were let down by the basic retail package, especially considering the price point. To be fair, other companies are slimming down their boxes too - the HTC 10 skips the headphones in some markets, and the Galaxy S7 doesn't come with a quick charger everywhere while some LGs come without a fast charger too.
Sony Xperia X 360° spin
The Sony Xperia X brings the screen size back to 5", so it's slightly smaller than the Z5 (but bigger than the Z5 Compact). It is roughly the same size as an Xperia M5. Slightly heavier though at 153g, in part due to the use of metal. It weighs the same as the Z5.
Hardware
The Sony Xperia X has been forged in the same fires as the Xperia Z5 - it's a stark and restrained aesthetic of boxy, rectangular design mixed with rounded-off sides and a side-positioned fingerprint reader.
The rounded sides are complimented by the 2.5D glass that slopes into the them. The transition is smooth - a boon for side-swipes and a small but meaningful detail that contributes to the premium feel.
Two notches are cut into the front glass to give the stereo speakers room to let their voice out. They are a throwback to the Z3, unlike the Z5 where they were placed closer to the top and bottom edge.
The front glass is scratch resistant, but Sony hasn't mentioned any brand names.

On the top half, there's a 13MP selfie camera - the Z-series were so focused on the back camera, so they only used to get 5MP front-facers. This camera is serious stuff - 1/3" sensor and a f/2.0 aperture, not too different from the specs of an iPhone 6s' primary camera.
The back is flat and made of metal with a frosted finish. The key placement is much the same as the Z-series as well.

The Xperia X weighs a hair over 150g, and the weight is evenly distributed. With Sony's choice of materials, the heft helps sell the quality feel.
The sides of the phone are key to the Xperia design. The round button of the past is now the Power key/Fingerprint reader of today. The key is recessed, preventing accidental presses. The built-in scanner is also fast and accurate.
We're still not happy about the placement of the volume rocker. It's between the Power and Shutter keys, so you have to tilt the phone sideways so your thumb can reach low enough. Sony is the last holdout for hardware shutter keys, and the benefit of having one is less certain when you won't be able to take pictures underwater.
On the other side of the phone is the card tray. It can be accessed without eject pins and it holds a nanoSIM and a microSD card. The Sony Xperia X also has a dual-SIM version. Note that it uses a hybrid slot, so if you need a microSD card you might as well get the single-SIM phone.

One annoying thing is that the phone immediately restarts when you pull out the tray - no questions asked, no chance to properly exit apps, no option to prevent the reset. Yet Sony has not enabled the Adoptable Storage feature of Android 6.0 Marshmallow, which would be one reason to restart the phone as soon as the cards leave it.
At the bottom is the microUSB 2.0 port and the mic, there's a secondary mic on top.

Display
The Sony Xperia X brings a Bravia, Triluminos, X-Reality display (hey, the names match!), 5" big with 1080p resolution. Sony won the sharpness wars with its 4K Xperia Z5 Premium, so the Xperia X is free to go for quality instead of bragging rights of a QHD display.
All those brand names really stand for an IPS LCD built on the Quantum Dot technology. It generates colors in a different way than vanilla LCD's and you can tell - even if you're used to AMOLED, the saturated colors of this screen look spell-binding.
Sony Xperia X review
Despite their surreal appearance, Sony managed to keep color reproduction fairly accurate - the display scores an average deltaE of 4.0 - that's more than the best in this regard (the Galaxy S7 and iPhone 6s), but it's still better than quite a few devices (the Xperia Z5, LG G5, and Huawei P9). It's really the white balance that's off (it has a blueish tint), the rest of the color reproduction stays mostly under a deltaE of 6. The biggest deviation was 9.4.
There are sliders to adjust white balance, but you need to have a calibration tool as you really can't do much by eye.
Sony also worked to improve contrast and the Xperia X scores 1,200:1, better than the 1,000:1 the Z5 managed and the 800:1 of the Xperia M5. This was largely done by improving the black levels, which are still on the high side. Even so, in the dark, you can get the brightness as low as 4.9 nits, a boon for late-night notifications when a bright screen would blind you.
Sony does image post-processing in its gallery. You can turn it off, switch to X-Reality mode or go all in with Super-vivid mode (delivering self-described "surreal" images).
These modes sharpen images, boost contrast and (in super-vivid mode) enhance colors. You can get a side-by-side comparison to help you make your choice too.
The sunlight legibility marks a small improvement over the Xperia Z5 and M5. It's on par with, say, LG G5, but behind some mid-range AMOLED-packing phones.
The Display settings have a few additional perks. You can enable double-tap to wake (off by default), Glove mode (for cold winters) and Smart backlight control (keeps the screen on while you hold the phone).
Connectivity
The Sony Xperia X comes in single- and dual-SIM versions, ours is of the single-SIM kind.
For mobile data, LTE Cat. 6 (300Mbps down, 50Mbps up) along with HSPA as a fallback (42.2Mbps/5.76Mbps). You also get dual-band Wi-Fi a/b/g/n/ac (the Xperia M5 lacked ac), Bluetooth 4.2 with aptX and Low Energy, NFC and FM Radio with RDS (we know it's important to some people).
The Wi-Fi connection can be used for screen casting - either via Miracast or Google Cast. This goes great if you connect a DualShock controller, the Xperia X becomes a portable console. For cars, MirrorLink can connect to your head unit.
The microUSB 2.0 port (yep, no Type-C action from Sony in the foreseeable future) lets you charge the phone as well as hook up USB storage and accessories. MHL is not supported, there's no wired way to connect to to a TV.
Battery
Ask any Xperia owner about battery life and you'll hear good things. But the Sony Xperia X comes with a sealed 2,620mAh battery. Is it enough? That's the same capacity as the Xperia M5 and actually a bit less than the Xperia Z5 Compact (2,700mAh).
Note that the Xperia X is the first phone to launch with a Qnovo battery. It supports fast charging (Quick Charge 2.0 in this case)), but the company behind it claims it has a longer life and will last hundreds of charge cycles more than a conventional Lithium battery (especially one that's being fast-charged). This means that a year or two after you buy it, the X will continue to offer solid battery life while an aged regular battery will not be able to hold much charge (and this is important for a phone with a sealed battery).
Additional improvements, including a new chipset, help the Endurance rating to a good 67 hours. Not the best we've seen (Z3 Compact was a wonder), but we think it's actually an improvement over the Xperia Z5.
It comes down to the testing procedure - we used to set the brightness slider to 50% (which for the Z5 meant a low 90nits), but now we test all phones at 200nits. The only test the Xperia X loses compared to the Z5 is the browser test, but we think at equal brightness the Z5's lead will shrink.

In comparison, the LG G5 scored 60h (50h with Always On screen), HTC 10 did 66h, Sony Xperia Z5 73h, Huawei P9 75h, Samsung Galaxy S7 80h (49h with Always On).
Sony's Stamina battery saving feature comes standard here. It has two modes: regular Stamina, and Ultra Stamina. The first disables non-essential features like GPS and vibration, and takes performance down a notch, but the Xperia does remain a smartphone.
Ultra Stamina is for absolutely dire occasions when you don't expect to be able to find a power outlet for a prolonged period of time. Enable that and it's back to basics where you get a single homescreen with access to the dialer and contacts, text messages, camera and clock.
Marshmallow-first Xperia
The Sony Xperia X comes with Android 6.0.1; it's the first Xperia to launch on Marshmallow (older phones are getting updated to it). Sony put its usual light-but-functional Xperia skin on top.
Sony Xperia X review
Keep in mind we use "light" in terms of the number of changes it makes, not how much storage it uses up. The X is available with 32GB of storage only, the Sony software reserves 12GB of that, leaving 20GB to the user. If you need more, add a microSD card.
The fingerprint reader is a recent addition to the Xperia line and Sony firmly believes the best place for it is on the side, integrated into the Power button. We can't deny the convenience, waking the screen and unlocking the phone are tightly related. There's optional tap-to-wake if you just need to check notifications (there's a notification LED in the top loudspeaker too).
Smart Lock gives you conditional security - trusted nearby devices, locations, faces, or voices can allow you to skip the security unlock protocol.

We had a good experience with the fingerprint reader. It's fast and fairly accurate. There's an animation that slides the lockscreen away from your thumb (as if you pushed it out of the way), which helps hide the small delay, so it feels seamless.
The homescreen appears unchanged. This includes the swipe down gesture, which shows a screen of the apps you use most along with recommendations for new apps to install. A search field is highlighted so you can start typing the app's name immediately.

The traditional app drawer is still on board and it features an above average amount of vendor apps. Sony takes great pride in their AV prowess, so you know they are going to swap out the base Android Gallery, Music and Video players, media editors too.
The notification area is plain Android. You can re-arrange the quick toggle tiles and adjust the screen brightness. Note that just like in vanilla Android, there's no toggle for Auto brightness (you need to go into the settings for that). That's the one thing we don't mind skins changing.

The app switcher is similarly a vanilla Android affair with the 3D rolodex look.
The small apps are gone, however, and there is no longer floating app multitasking.
That's not to say apps are allowed to do as they wish, the Smart cleaner feature will periodically empty the cache of apps you haven't used in a while. You can switch this off or just manually tell it not to bother for certain apps.

One thing Android has been missing for years is a proper backup solution and Sony gives you one. It can backup applications, contacts, messages, phone settings. The backup info itself can be stored on your Sony online account, on the microSD card or an external USB device. Backups can be scheduled, including conditions like "Connected to Wi-Fi" and "Charging device" (the latter means you can build a charge/backup dock if you are crafty enough.
Performance
The phone is powered by a Snapdragon 650 chipset. This means you get the new Cortex-A72 cores - better, faster than the A57 they replace - but only two of them. They are paired with four Cortex-A53's so the chipset is a replacement of the Snapdragon 808 (2x A57 + 4X A53). That said, this chipset is built on the older 28nm process while the Snapdragon 808 was built using the 20nm process.
Despite this fact, in multi-core CPU speed, the Xperia X does better than the LG Nexus 5X with S808, and it even matches the Xperia Z5, which uses an S810 chipset.
