My old Samsung galaxy note 10.1 gt-n8000 suffers from battery draining while charging and I don't know why.
It won't charge when it's completely turned off.
The red X does not appear while charging.
I've tried basic things such as reinstall the system, cleaning the docks, different chargers.
I've also replaced the whole battery (non original) and even changed the charging dock from a 0.4 to 0.5 (Original)
When I first got the new battery it was 40% charged so I tried to keep charging it both turned off and on but it doesn't work.
I haven't drained the new battery to 0% yet, fearing that it might get worse.
One thing I've noticed a couple of days after I changed the battery, was that its time and date were completely wrong but the battery was still on 37%.
Could the separat battery clock be the problem somehow?
Would appreciate any tips on how to fix this! Thx
