    Hi, i asked question about battery problem, so i deleted chache memory in recovery mode, and now i do not have problem with baterry display, now i have battery problem. So my device turned off while playing Boom Beach, then i turned it on normally and i had 1% battery. Then i put it on charger and it charged to 28%, and after about 15 s it showed 100% charged. I disconnected it and same problem happened again. Please help.

    Are you the original poster on this thread?

    You may have to recalibrate the battery meter. Use the tablet until it shuts off on its own. Then charge it on a wall outlet without disturbing it for 6-8 hours. Power on again, and use it normally again until it shuts off on its own. Repeat 2-3 times. Then see if it works more normally.
