I have a lumia 1020. the phone battery drains out even when charger is connected.

[WPCentral Question]

The phone shows charging indication when I connect the charger, but as I am using it along with charger connected, the phone battery drains out and the phone turns off with the charger connected.

it takes a hell lot of time to charge now. i kept it for charging for 7 hours and i could only charge upto 81%.

it gives a lot of problems when booting. boots 10 15 times before it turns on.

Might be time for a replacement. Sounds like the battery cells are dead or dying

I would try a different charger and wall plug first.
