To be perfectly frank, many of us thought we would never see the day OLED made its way on to an Xperia phone. But it finally happened and it's a really glorious sight to behold. Just to clear the air a little bit, we're not insinuating that LCD is bad in any way. On the contrary - when done correctly, it can provide a great visual experience. It's just that OLED has quite a few extra benefits to offer that more and more traditionally LCD-friendly companies like Apple are starting to appreciate and adopt.OLEDs galore: Xperia XZ3 next to the Galaxy S9+
The overall benefits of the tech are clear, but it might just be up to Sony to convince its users to take the plunge as well, considering the long years of LCD-only diet, accompanied by frequent praise for the benefits of the IPS liquid crystal technology.

For instance, looking at the raw test data, there is no denying the superiority of having true blacks and infinite contrast. We do have to note, however, that, compared to other Xperia devices and many directly competing flagship offers, the XZ3 lags a bit behind in the brightness department. The panel Sony chose only goes up to 440 nits or so and has no "max auto" overdrive mode.
These brightness concerns haven't affected sunlight legibility at all. In fact, the XZ3 is on par with recent Samsung devices, at the very top of the food chain in this respect. We can only imagine it's due to some very non-reflective surface on the handset.
The sub-optimal brightness results aren't really enough of a deterrent against OLED and the XZ3 in out book. If you find yourself in need of some extra convincing before boarding the OLED train, just go and check out the XZ3 in person. Specifically, the collection of demo videos Sony pre-loaded on the phone to showcase its shiny new panel. The vibrant colors, perfect blacks, infinite contrast, fluidity and snappy pixel response times just make for an objectively better experience than any Xperia LCD we have seen in the past.Xperia XZ3 vs. Xperia XZ2
Plus, Sony made sure to gear up the new shiny panel with its patented set of familiar display optimization tech. Namely, TRILUMINOS technology, X-REALITY, and a Dynamic Contrast Enhancer. So long-time fans don't have to feel like they are missing out. In fact, Sony claims it made quite a few AI-driven improvements to its SDR to HDR enhancer for the XZ3.Color modes are the same on the Xperia XZ2 (left) and XZ3
Speaking of HDR, Sony gave the new display its full HDR treatment, even sprinkling a few cherries on top. Just like many of its siblings, the XZ3 supports 10-bit colors and is certified for the BT.2020 standard. The display is also certified for HDR10 playback, which is the defacto standard for HDR streaming, on platforms, such as Amazon, Netflix and YouTube.
Supporting just the right amount of HDR is somewhat of an issue in 2018, with segmentation and competing standards all throughout the tech realm. In an effort to address this, Sony is now recording HDR content in accordance with the HLG standard. This is a very flexible approach, that does not alienate SDR-only playback devices and also plays well with YouTube's format system, making for easy content sharing and delivery. Quite a major concern, when it comes to HDR video. We'll go more in depth on HLG in the video section of the camera page.
Clearly, Sony has put quite a bit of effort on the HDR front, facilitating easy capture and playback. And for most users, those two points will be more than enough. However, not all HDR-certified devices are created equal and it is worth noting that by all accounts, the panel on the XZ3 is on the lower end of that spectrum.Two generations of HDR screens - Xperia XZ3 (left) and XZ2
Without getting into too much detail, let's just say, standards vary and are often bent slightly to accommodate a larger number of devices. For instance, the most widely used Ultra HD alliance HDR standard originally required a maximum brightness of 1000 cd/m2, a black level of less than 0.05 cd/m2 and a contrast of at least 20,000:1. Obviously, by nature, OLED panels have no issue with the contrast part. Which, in turn, means that even if they don't reach those eye-blinding brightness levels, they will still benefit from an HDR signal. And the reality is that for most OLED panels, even when measured in a tiny spot, 1000 cd/m2 are simply unattainable.
Hence, a more OLED-relevant standard was developed by the Ultra HD alliance, requiring 540 cd/m2, the same blacks and a contrast of at least 1,080,000:1. Now, since this lacks any additional parameters as to the size of the measured area for that peek brightness (an important aspect for testing OLED screens). Our standard tests measure brightness with the test pattern filling 75% of the area of the panel - a case in which the XZ3 fails to meet those requirements. But is should be noted that competing offers, like on recent Samsung devices do manage to cope. Shrinking the area of the test pattern, we were able to measure 540+ cd/m2 on the XZ3, so Sony is definitely not cheating.
VESA has a competing and arguably more precise HDR standard, in recently released, which defines three tiers of HDR (HDR 400, HDR 600 and HDR 1000). Without digging too deep into the standard itself, we can clearly see the XZ3 only covers the first level. The point we are trying to drive across here is that, as far as HDR screens go, the XZ3 is not the end-all of mobile devices. Something we felt we had to address, after reading some of the discussions about Sony's latest flagship.
That being said, the XZ3 is not necessarily any worse off than most consumer-grade HDR tech, currently out there. Standards like HDR 600 and especially HDR 1000 are still meant for professional-grade laptops and monitors, not consumer smartphones. The only tangible benefits Sony offers with its approach to HDR are a wider compatibility for both consumption, as well as content sharing.
Quite frankly, even the "pro-sumers" out there, the ones willing to drop money for a beastly 2018 flagship, like the XZ3 won't likely be consuming too much HDR content, given the lack of a steady source of such material. General color accuracy, on the other hand, might be a bit more important to a wider portion of XZ3 potential buyers.
Honestly, the XZ3 didn't really blow us away in this department. With the "Standard" color mode, it ships in, our review unit managed an average deltaE of 6.2 and a maximum of 9.8. The main problem seems to be a blue tint, a cold hue, which is fairly common on mobile devices. Luckily, there are both other color profiles to try out on the XZ3, as well as a custom white point adjustment.
We tried fiddling about quite a bit with the manual adjustment, measuring with the colorimeter every step of the way. The "Warm" color profile remedies the blue situation quite a bit and brings down the delta values. If you don't feel like wasting too much time, you should go with that. Otherwise, you can use the custom white point values from the screenshot, which brought our dealtaE calues down to an average of 4.6 and a maximum of 9. And that's about as color-accurate as the Xperia XZ3 can get.
All this display talk and we still haven't even mentioned resolution. With QHD+ native, the XZ3 sits nicely, in the middle ground between the FHD+ XZ2 and the insane 4K resolution of the XZ2 Premium. It's an incredibly sharp display.
Oh, and there is one more benefit to be gained from the OLED technology as well. Sony has implemented an Always On Display option for the XZ3. It's called "Ambient display" and already comes with a selection of five different clock styles, extensive notification controls, music controls, as well as some user-customizable graphic content.
Stickers allow you to place a static image from a pre-loaded set or your gallery near the bottom of the display. There is also a Photo playback option, which surfaces around windows with your photos in random sizes and locations on your lock screen. The XZ3 typically selects the most recent shots you have taken, but if it finds shots of the place you are currently at in your gallery, it will start cycling those. Neat!
The Xperia XZ3 is fairly beefy, which typically leaves more space for a sizeable battery, to match. With a typical capacity rating of 3,300 mAh, the pack, inside the new flagship is pretty adequate in size. Sony obviously did their best and at least tried to cram as much juice in there as possible, compared to the Xperia XZ2 and its 3,180 mAh rating.
That's still shy from the 3,500 mAh of the Xperia XZ2 Premium, but that is an entirely different beast. One that, most notably, needs all the electricity it can get for that power-hungry 4K panel of its. In contrast, one of the many benefits of switching to OLED is a lower typical power draw from the display - likely the single biggest consumer in a modern smartphone. All this, combined with the XZ2's great 88-hour endurance rating, naturally set our expectations pretty high for the XZ3.
And we have to say, the XZ3 definitely delivers. Perhaps not quite the astonishing improvement over the XZ2, we were hoping for, but the XZ3 still won't fail to last you through an entire day. Naturally, it should be noted that our standby test was conducted with the always on display feature Off. OLED or not, it drains the battery really fast.
Our endurance rating denotes how long a single battery charge will last you if you use the Sony Xperia XZ3 for an hour each of telephony, web browsing, and video playback daily. We've established this usage pattern, so our battery results are comparable across devices in the most common day-to-day tasks. The battery testing procedure is described in detail in case you're interested in the nitty-gritties. You can also check out our complete battery test table, where you can see how all of the smartphones we've tested will compare under your own typical use.
We're less excited about the charging situation. You see, our review unit arrived with the UCH20 adapter rated at 5V/1.5A, which takes a lengthy 2:50 hours to get the XZ3 from flat to 100% and is only a quarter of the way to full after a half hour charging session. The much better QC3.0-compliant UCH12 adapter supplied with the XZ2 Premium that we had on hand, yields almost entirely the same numbers, and so does a third-party QC3.0 charger - not really surprising since Sony makes no QuickCharge-compliance claims in the Xperia XZ3's specs.
In fact, Qualcomm's QuickCharge is incompatible with USB Power Delivery, which is the standard supported by the XZ3. However, you'd need a PD charger, which Sony isn't making yet - seems like a good explanation why there isn't one in the box. Anyway, we tried with the Pixel 2 charger, and oh miracle - the XZ3 does top up faster. It still takes a little less than 2:30 hours for a full charge, but a 30-minute stint leaves you with a more usable 43%, and an hour into it you'd be looking at 73%, as opposed to the 55% with either of the Sony chargers above.
Don't get us wrong here, we're all for USB Power Delivery and applaud Sony's push for this standard, but a compatible charger in the box would have made a much stronger statement.
The Xperia XZ3 practically borrows its audio setup entirely from the Xperia XZ2. That, of course, entails some great things, like the impressive stereo speaker setup and the intriguing Dynamic vibration system. But, also, some less than ideal choices, as far as most fans are concerned, namely the refusal to bring back the 3.5mm audio jack.

Interestingly enough, the XZ3 appears to have slightly better acoustic properties than the XZ2. Perhaps, the taller body helped clear out bigger chambers for the speakers. Then again, it might come down to tuning. Regardless, the XZ3 managed an Excellent loudspeaker score.
As expected, turning on Sony's ClearAudio+ enhancement does take away some of the loudness. However, the hit isn't all that big on the XZ3, even though the overall loudness score dropped worn to "Very Good". In any case, ClearAudio+ gives back more than enough in a richer sound stage to compensate for a few decibels less in the volume department.
The Sony Xperia XZ3 delivered perfectly accurate output with an active external amplifier, while its performance with headphones was good to very good. Stereo crosstalk rose a moderate amount with our standard set, while the kind of intermodulation distortion that appeared is hard to detect outside a lab.
Much like most of its predecessors, though, the Xperia XZ3 failed to match its rivals when it comes to volume levels. It was below average in both tests, suggesting that its loudness might be problematic with high-impedance headphones.
