Why does my batter drain really fast on my Samsung Tab 3 7''?

Battery life issue with a Samsung Tab 3 7''

My Samsung Tab 3's battery life drains really fast (100% to 1% in 10 mins) and i know that it is a bug because, if i put it into sleep mode for 30 mins, it goes back up to the original battery percentage. I have had my tablet for about 9 months and I have had the issue for approx 3 months.

Welcome to Android Central! Wow, that's weird. What happens if you keep using the tablet when it runs down that fast? Does it actually shut off automatically, thinking the battery is truly about to die?

Hi, yeah, If I charge it to 100% battery and then unplug the charger, it drains to 1% battery, stays like that for about 3 mins and then turns off. If I then leave it for about 15 mins and turn it back on, the battery level will go back up to 95%

I'd guess the battery is failing--you could look into replacing the battery, but that you would either have to bring it to a shop or try doing it yourself (there are probably lots of YouTube videos showing how to do it).
