Huawei Mate 20 Pro packs a curved 6.39" AMOLED screen with a large notch at the top. The resolution is 3,120 x 1,440 pixels, which makes for flagship-grade 538ppi density. The aspect ratio is 19.5:9 - among the tallest the market has to offer so far.
The screen supports the large DCI-P3 color space, and it can display native HDR10 content.
According to the most recent reports, Huawei has opted out of Samsung's screens and chose BOE for its main OLED supplier, while LG is the backup one. And the subpixel arrangement is easily giving away that switch.
All Samsung OLED panels have Dimond PenTile subpixel arrangement, while the BOE's OLED matrix uses Triangular PenTile pattern also known as RGB-Delta. It has the green subpixel split in two, but other than this oddity, the panel is still PenTile, just with a different arrangement that was once very popular on the CRT monitors.
The screen of the Mate 20 Pro has two Color modes - Normal and Vivid. Each of those also has three sub-modes - Default, Warm, and Cold.
The Vivid option represents the DCI-P3 color space, while the Normal one switches to sRGB. Huawei hasn't specified this anywhere, so we had to find it the hard way - by testing the screen in our lab.
Anyway, the Mate 20 Pro comes set on Vivid by default and we suggest leaving it this way. The mode offers 508 nits of (manual) maximum brightness, but it can go as high as 660 nits in bright light if you leave it on auto. There is a minor light bleed on the pitch-black screen, but this is not unseen and nothing to worry about.

The average deltaE we measured for the screen on Vivid is 4.7 with a maximum deviation of 7.5, which is not the best accuracy, but fine enough. You can fix the bluish whites by switching to Warm color temperature, but the overall accuracy won't improve by much.
The color accuracy for the Normal (sRGB) mode is pretty much the same as for the Vivid (DCI-P3), and again, switching to the Warm setting won't do much in improving it.
The sunlight contrast on the Huawei Mate 20 Pro is excellent, if not class-leading, but we expected nothing less from an AMOLED screen.
The Huawei Mate 20 Pro is powered by a large 4,200 mAh battery. Being the more premium Mate from the new duo, it enjoys Huawei's new version of SuperCharge that goes up to 40W. The charger is rated 5V/2A, 9V/2A, or 10V/4A.
Unlike the regular SuperCharge, this one uses higher voltage and the battery does heat up. Huawei says the battery was TUV-certified for safety and users shouldn't have any worries.
So, the bundled cable and charger can fill a flat battery up to 74% in just 30 mins, 90% in 40 mins and 100% in 60 mins. That's not Oppo Find X Lamborghini Edition fast, but it's among the fastest solutions you can get today and downright impressive. The obvious downside is that you need proprietary chargers and cables for that to work.
In our testing, the Mate 20 Pro lasted upwards of 15 hours looping videos and fourteen hours running our web browsing script. The 3G voice call test returned a 29h talk time. All three of these numbers are slightly better than what we got out of the P20 Pro. The overall Endurance rating ended up 85 hours, though. That's lower than what we expected after such an excellent job on the standalone tests, but the standby performance is just average and it took its tall.
If you turn the under-display fingerprint sensor off, you can get a few extra hours due to the improved standby performance but the difference is not that huge to make disabling the feature completely worth it.
Our endurance rating denotes how long a single battery charge will last you if you use the Huawei Mate 20 Pro 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.
Huawei Mate 20 Pro enjoys the same stereo speakers we've previously heard on the P20 Pro and Mate 10 Pro, among other devices. And while Huawei failed to mention this, it's also the same setup the regular Mate 20 has.
Huawei hasn't upped its game when it comes to the speakers - it still uses the tiny and squeaky earpiece for a second speaker, and it still sounds rather cheap. Yes, it does the stereo effect, but the loudness of the speakers is mostly uneven, and you can tell. At some point, it might even become annoying.
Then there is the thing with the primary speaker being inside the USB port. While Huawei can argue the port is used as a chamber and amplifies the sound - it isn't louder than what we measured on the Mate 20. The sound does sound a bit deeper, but it's a minor difference.
Finally, when plugging a charger, the sound through the USB port does take a hit and it's as big as 50%. But then its loudness becomes more even with the earpiece's, so there is that.
So, the Huawei Mate 20 Pro speakers scored a Very Good mark in our loudness test, half a decibel shy of Excellent. The sound quality is about average though, far from the best in the industry. While playing some music, the audio was loud enough, but it's rather shallow and often squeaky.

The Huawei Mate 20 Pro delivered a perfectly accurate output when connected to an active external amplifier, which is what we’d expect from a flagship these days. Even considering the price point, however, the clarity of its output with headphones was impressive. Stereo crosstalk barely increased, which is a real rarity and the other readings were hardly affected either.
The area where the Mate 20 Pro doesn’t shine is loudness - it was above average without headphones and only average when we plugged those in. So, all in all, it's a very good, but not quite the perfect showing.
