Wi-Fi Galaxy tab 3 7.0"
It started with my tab just shutting off whenever it reached 30% some months ago, but this didn't really concern me as I'd normally charge at around 40%. I didn't care too much, then last month it started cutting off at around 50-60% and then it just keep rising higher and higher until this Monday it cut off on me on 94%.
It doesn't start back when it cuts off unless I plug in the charger.
Now it cuts off anywhere above 60+. I've noticed the pattern if, I'm watching a movie or something, it'll cut off when I come out of it. Last night it cut off on me at around 66%. I plugged it in for 2 minutes and started a movie then I unplugged it. I let the movie play on and run down the battery to see how far it would go because I was doubting the accuracy of the battery indicator, because it has this tendency to linger at 100% for a while when I unplug the charger. It went down all the way to 28%, a warning popped up that my charge was below 30% and to close some apps to conserve battery life, but then an email came through and i came out of the movie to check it and as soon as i was out though it cut off and wouldn't restart unless I plugged it in.
When I plugged it in, it said 6% charge (from 28% before cutting off to 6%), I pulled out the charger and it dropped to 5%, but the screen didn't dim or any of the automatic power save stuff. When I plugged the charger in again it was saying 9%. I left it charging and started an app I found on Google Play https://play.google.com/store/apps/details?id=air.ynfo.batteryrepair to see if that would help.
Anybody have similar problems like this? If I take off the back as I saw in another thread about the tab not charging, would that help in this situation? Is there anything I can do? It hasn't fallen or anything. It's about a year old.
