why is my samsung tablet draining in a half hour of use

[AC Question]

I can have it pluged in and fully charged even when I don't use it it loses its battery life. That is even when nothing is running

If it drains when the tablet is turned off, it sounds like a physical problem in the tablet - a short or a bad component.

Hi and welcome to AC. Which Samsung tab do you have?

Welcome to Android Central! Charge up to 100%, then let it drain to 20-30% with normal usage, without charging in between. Then show us:


1. The main Settings>Battery screen.
2. The fullscreen battery graph screen (which shows Awake time and Cell Signal Strength).
3. The Screen category (to see total Screen On time).
4. The Cell Standby category, if present (to see Time Without Signal)--this is only if your tablet is 3G or 4G capable.

You might have to install a 3rd party battery monitor, like GSam Battery Monitor, to get the Cell Signal Strength graph.
