Galaxy Tab 3 10" turns off when unplugged

[blondie_mom]

My son's tablet is a year old and last night it turned off while he was playing on it. I tried to turn it on but no good. I had to put it on a charger and hold the power and home keys and it would start up. The battery level was at 40%. As soon as it is unplugged, it goes black and wont turn on.

Help please!!

Welcome to Android Central! Try keeping it plugged into a wall outlet overnight, undisturbed. Then power on again after unplugging it. Still not turning on?

This didn't work. Still turns off when I unplug from charger. I tried to do a hard reset but I can't do that either.

You could try charging with a different cable and wall plug. If that doesn't work, then the battery itself may have failed, in which case you'd have to bring it to a repair shop (or consider getting a new tablet).

I think it's the battery. I switched chargers and let it charge overnight. I did another factory reset and as soon as I finished the setup, it went dead.

So disappointed because the darn thing isn't that old!!

Unfortunately, batteries can be defective. Also, the overall battery lifespan can be shortened by repeated deep discharges (i.e., if you regularly let it drain to zero or close to it). It's optimal to start recharging when you hit 30-40%.
