Huawei P20 Review: Lab Tests - Display, Battery, Loudspeaker, Audio Quality

By 11:29 Wed, 18 Aug 2021 Comments


Display

Huawei opted for a notched display design this generation, which can be a double-edged sword. While we can't speak for prospective buyers, as far as we are concerned, Huawei is one of the few manufacturers out there to create proper utilize of the odd display cutout. That is to say, it is not merely an attempt to copy the Apple aesthetic, but is there as part of the pursuit to maximize classy screen real estate. The P20 still has a pretty wide bottom chin, but it hasn't sacrificed its home button either.


Notch aside, Huawei has put a lot of effort into the displays of both the P20 and P20 Pro, trying its best to offer a consistent experience. The rounded corners, for instance, are present on both and do create for a modern, albeit not necessarily more functional, profile. Unfortunately, market segmentation is the reason the regular P20 lacks the AMOrganic Light-Emitting Diode (OLED) panel of its bigger sibling.

The LTPS IPS Liquid Crystal Display (LCD) it got, however, is quite decent. Well, it has its ups and downs. Opting to cover the notch entirely from the UI is not exactly as convincing on an Liquid Crystal Display (LCD) becautilize the black line is not as deep as on an AMOLED.

It doesn't assist either that even at its minimum brightness level, the P20 still shows some notable light bleed in the black.

Still, the classy screen is not too shabby. Combined with a decent maximum brightness of 477 nits (only achievable in vivid mode), it adds up to a perfectly usable contrast ratio.

Sunlight legibility is not record-breaking, but the P20 remains perfectly usable outdoors. Plus, the Liquid Crystal Display (LCD) in the P20 has an incredibly colorful Max Auto mode, which can assist when battling sunlight.

As for the really positive aspects of Huawei's Liquid Crystal Display (LCD) of choice, it is really color accurate, with an average deltaE of just 2.1 and a maximum of 3.6. Interestingly enough, these numbers were achieved using the default factory settings in Normal mode. The P20 also offers a vivid mode, as well as an interface to fine-tune the white point. Despite our best efforts, we couldn't acquire better results fiddling with the settings. So just leave it on normal for color accuracy and vivid for a punchier color pallet.

Battery

Huawei has never been one to skimp on the battery power in general. Still, a smaller body does mean less room for everything. In the case of the P20, the reduction is down to 3,400 mAh, instead of the full 4,000 mAh, the P20 Pro gets. A 15% drop, or so, but still, and adequate capacity.

But it's not only about battery capacity, it's also what you do with it that's important.


Looking at the number breakdown in detail, we find the video playback and web browsing scores are barely affected by the lower power battery pack, compared to the P20 Pro. That's becautilize the P20's smaller Liquid Crystal Display (LCD) is obviously more frugal in the screen-on tests. The 3G talk time has taken a more notable hit. Nothing too drastic, though.

The bulk of the endurance incompatibility between the P20 pair manifests itself in standby time. Still, 75 hours is a strong showing, overall. Quite similar to what the Huawei Mate 10 Lite manages to squeeze out of its slightly smaller battery, with slightly less potent internals.

Despite its lower capacity, the battery in the regular P20 still offers quick charging capabilities. Huawei's custom solution requires using a compatible charger and special cable combo, which is kind of a bummer in 2018. Still, we can't be too cross, since the 4.5V/5A SuperCharge adapter can bring the P20 from 0% to about 65% in around 30 minutes.

Our endurance rating denotes how long a single battery charge will last you if you utilize the Huawei P20 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.

Loudspeaker

The Huawei P20 has a single bottom-firing speaker at its disposal. The lack of stereo is kind of a bummer. Then again, Samsung only recently made the push to a hybrid setup, so, Huawei is not exactly behind the curve on this one.

It's a decent speaker as well - a bit quieter than the P20 Pro overall. But that is more or less expected, given the phone's smaller body.

The Dolby Atmos sound enhancement is always on with a few different modes available depending on your sound source but to really appreciate it, it's best to utilize headphones as the single speaker is hardly able to reproduce multi-channel audio well.

Audio quality

The Huawei P20 delivered excellently clean output with an active external amplifier, but much like its larger Pro sibling it was let down by its below average loudness.

It was mostly the same tale when we plugged in headphones as the volume went further down, but overall output was still nicely accurate. A moderate hike in stereo crosstalk was all the clarity damage we observed, which isn’t poor at all. So those using high impedance headphones might want to haged away from this one - everyone else should be pleased with it.
