Galaxy tab 3 SM-T210 Problems with battery meter

Same problem here. Changed battery and problem remains.

I can use it with 1% for hours, seems some problem with battery meter. I'm about to flash a custom rom / bootloader/ recover from scratch wiping all to see if it helps.

Otherwise I'll need to use it at 1% forever

Edit 1:
Absurd! Seems this device forgot the low battery level...
Replaced battery, flashed another stock clean rom with latest version (4.4.2)
This "drain" also happens on recovery screen.

It works with 1% during hours... I' ll try to let it drain all (wait it to really discharge all) and recharge 100% again.

Edit 2:
Haha, went to recovery right after post last update, then it increased from 1% to 100% without the charger

Seems something is messing up with the battery levels on android OS on all versions. I'll let it discharge on recovery... at least seems it is the correct level... let's see if the device learns again the battery levels

Solved: removed battery, hold power button for 30 seconds (to clear all energy accumulated on circuit (capacitors?!) and plugged it again. Worked.
I read about it on some google search.
