I have to really praise Huawei for the fact that they’re actually bumping up the battery capacity each generation. Beauty is in the eyes of the beholder, so the phone can be thicker or thinner and there will still be someone complaining about it – but a larger battery is something that everyone loves.
With a 3,400mAh battery and 10nm process technology and a dedicated NPU to handle all of the intense image recognition algorithms, the Huawei P20 performed very well in our battery test. Lasting for more than 10 hours in the test, it has a commendable battery life.
Huawei’s SuperCharge using another standard of fast charging compared to the standard Qualcomm has. The SuperCharge is the same as the P10 – it outputs a maximum of 5V at 4.5A, a total of 22.5W. With such high amount of current, a thicker cable is surely needed. That’s why the Huawei P20 comes with this thick cable that has purple USB headers.
In terms of its charging speed, the SuperCharge does have a rather unique charging curve. The entire charging curve looks like a quadrant of a circle, and manages to charge to 100% in just 1 hour and 30 minutes!
