The charge - 9%. Connect the AC charger (the phone does not turn off) - current 0,11A. I tried to to connect to powerbank (phone is not off) - A current of 0,42-0,47 !!!
By the way, I have included in the settings "Saver in sleep mode" and the phone worked for about 3 days on a full battery charge, although (Android 5) I worked almost 4 days.
