The HTC 10 evo comes equipped with a 5.5" screen with QHD resolution. This is a Super LCD3 panel with 534ppi pixel density. Its Gorilla Glass 5 shield has been specially treated to be scratch, smudge and reflection resistant. Unfortunately, the chin around the Home button was quick to get covered in super fine scratches and we even managed to get a big scratch on the display. We recommend getting a screen protector for this phone.
HTC advertises the ruggedness of the screen and its suitability for outdoor use, those things aren't backed up by concrete numbers outside of a mentioning that they've tested it from a 1.6m of height.
We didn't test ruggedness, but when it comes to maximum brightness, the screen reached 525nits at full blast, a very good reading. There is an auto-brightness mode, but it offers no extra boost in very bright conditions.
The black levels are fairly low, similar to some high-flying flagships out there. This leads to the very good contrast ratio of over 1,300:1.
|Display test||100% brightness|
|Black, cd/m2||White, cd/m2|
The solid brightness and contrast reading translated to average (but usable) sunlight legibility score of 2.4. That's as much as the HTC 10 got (which uses Super LCD5, by the way). It's well below what a typical flagship would score (usually around 3.5).
At the lowest setting, the screen scaled down to 5.5nits. You can combine this with the automatic Night mode to prevent bright, blue light from messing up your body's natural sleep cycle (if studies are to be believed).
We were initially impressed to find a Color temperature setting, but testing quickly revealed that the HTC 10 evo doesn't provide a terribly accurate color rendering. Its readings are similar to the smaller HTC 10, which is to say, they are far from flagship quality.
Specifically, we got a 5.9 average deltaE and a maximum of 12.6. The white balance is too cool, easy to correct with the slider (we brought it all the way to the left). But that does nothing for color accuracy, we measured an average DeltaE of 5 and a maximum of deltaE 11 (and the maximum brightness dropped to 480nits). The Red channel, in particular, is way off the mark. You have got to remember that this test does not relate to saturation or punchiness of the colors in any way. It measures how closely would the screen render colors to the original when accuracy is important.
The results here is not ideal but phones like the LG V20, Huawei Mate 9, even the beloved Pixel XL and other high-enders don't do much better in this test. And those are a pricier than the 10 evo, so we think HTC picked a screen that delivers on what's needed.
The HTC 10 evo relies on Qualcomm's X10 modem, a part of the Snapdragon 810 chipset. This pegs the maximum LTE speed at Cat. 6 - 300Mbps down, 50Mbps up. That's slower than the Bolt in the US, which has Cat. 9 - 450Mbps/50Mbps. The 10 evo does feature full support for VoLTE and even VoWi-Fi (pending your carrier's cooperation).
Wi-Fi offers up to 802.11ac speeds, topping out at 433Mbps. Additional connectivity includes Bluetooth 4.1 (no aptX) and NFC.
The USB-C connector, for all its virtues, is a plain USB 2.0 connection. This means you won't get fast data transfers and goodies like wired TV out are missing as well. It does offer QuickCharge 2.0, which was current back when the S810 chipset was new.
The HTC 10 evo comes with a 3,200mAh sealed battery - nothing spectacular, considering it has to feed an older chipset connected to a QHD screen. A chipset that has a tendency to get hot under the collar no less (a sign of poor efficiency).
HTC is promising a full day of battery life and up to 23 hours of talk time, but we never managed to get close. After testing and retesting, the best we got out of the 10 evo was 17 hours. That's worse than the HTC 10 got with its smaller battery and it's an overall middling result.
Unsurprisingly, the 10 evo did not last as long in the web browsing test either. At 7 hours or so, it fell off the flagship region and was buried in mid-rangers. The evo matched the regular HTC 10 only in video playback and that time isn't spectacular.
The final Endurance rating of 58 hours is below what we've come to expect from phones in this price range. We could blame it all on the chipset, but the truth is that a 5.5" phone of this thickness can easily have 3,500mAh or more in battery capacity.
The HTC 10 evo features QuickCharge 2.0 and comes with the required charger. It puts out 15W all told (either 9V at 1.67A or 12V at 1.25A), but HTC is vague about the charge times.
