my phone drained out of power and when i charge it, it only shows that it is chrging then it turns off again. when i try to turn it on, it shows nothing. can anyone help me how to resolve this problem?
Try to change the battery (only for test) and try to charge/recharge the phone. The battery may need replacement! Your adapter may also be bad. Try to charge it vie USB cable.
p.s. Some of your apps can drain battery life very fast! Find in your battery settings (battery usage) the app which uses much battery and cut it off. That kills the battery and you must be care about it.
