Battery calibration
I have a rooted Nook HD+ running Android 7.1 and I decided to calibrate its battery.
I ran it down to zero as recommended then attached it to the mains. All I have had for several hours is a black screen with just the charging symbol (battery with lightning inside it). Nothing else, no progress bar, no charge %, nothing Androidy. Is this as it should be and should I just wait for several more hours or is there something wrong? Many thanks. |
