Battery & Charger

Huawei did a lot of “space saving” for the Mate 20 Pro – and they packed a massive 4,200mAh battery inside. Does it last long enough, though? Here is our PCMark test of the Mate 20 Pro’s battery life.

With the performance mode turned on and resolution cranked to the highest, the Mate 20 Pro is a little disappointing given that the Note9 with a 4,000mAh managed to perform just as well. Remember- the Galaxy Note9 has a 3.5mm audio jack, a microSD card slot, and the new Bluetooth-connected S Pen as well.

But the Mate 20 Pro can have its resolution changed and Performance Mode too. We tested even more and here is our result:

For the longest use time on the Mate 20 Pro, you’ll definitely need to disable Performance Mode and use 1080p resolution only. Lasting for more than 13 hours in the test, this is actually the longest lasting flagship smartphone in terms of battery so far.

Huawei’s SuperCharge charger

Huawei included a really thick USB-C cable and also a SuperCharge charger – which outputs a maximum of 40W. At 10V 4A, it’s definitely fast – and definitely hot as well.

Huawei’s SuperCharge warms up both the charger and the phone, making it warm to the touch. It’s not scorching hot, but just warm.

One funny behavior of the Mate 20 Pro is that all my apps are suspended while using the SuperCharge charger with the screen turned off. Even the battery logging app that I use was suspended, hence I was not able to get a complete charging curve data. After the battery reaches 100% charge, the app suspension stops.

We only managed to obtain part of the charging data. Other points were extrapolated.

From what I can see though, it takes about an hour to charge from 15% to a full 100%. That’s intense.
