Battery issues... Why is my device shutting off?

[Didier DJ]

I have a Galaxy Tab 3 SM-T310 and it gives me a lot of problems lately:
1. battery is draining pretty fast, but I use my tab mainly for games so I can understand
2. battery doesn't charge if tablet not turned off
3. tablet keep shutting off for no reason
Is it time to replace the battery?

Welcome to Android Central! First, it would be helpful to see some battery stats. 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).
3. The Screen category (to see total Screen On time).

Second, have you tried different charging cables and wall plugs? Chargers can fail unexpectedly. Also, are you charging from a wall outlet, or from a computer's USB port? The latter doesn't give much current, so if you're actively using the tablet and trying to charge through a USB port, the rate of battery use will probably exceed the rate of charging.
