1. Android Central Question's Avatar
    seems that my battery life is terrible. however, when it gets below 20% the screen goes black. i can hit the power button twice and it comes back on. the lock screen wants to use the iris scanner and then will go black again. i can actually type in my password without seeing the numbers and then when i hit power twice it will open and it wont' trigger the iris scanner so I can do stuff for another few minutes. then screen black again. this seems to be a new issue. is the battery bad ? is this a new failsafe thing?

    Welcome to Android Central! Which phone? A battery-saving mode might be set to turn on automatically at 20%, causing the screen to timeout more quickly, and restricting certain functions.
