Hello, I have a Huawei p10 lite. I noticed that when my battery is discharging, the sound of the discharging battery appears only when the battery is at 2%. On other phones, the sound comes out at 15% or 10%. I read about such a program from the Play Store, but I want it to be done systemically. Can it be changed somehow? I downloaded Total commander and I cannot enter the main directory of the system, for example in Huawei p8 lite where I can.
