It all happened a few days ago . I charged my nexus 7 to 100% (stock rom used for few months alr )and wiped the battery stats . Following that I drained the battery till 0% . After rebooting , the slow charging problem surfaced . I have already did a clean wipe and reinstall of stock 4.1.2 using nexus toolkit , the problem is still there . Help ?
I had this issue for a long time. Tried all the chargers and ROMs I could get my hands on.
Decided that it should be an hardware problem.
I opened up the Nexus 7 and re-soldered all the USB contacts.
I removed the flat cable that goes from the USB PCB Surface mounted connector and cleaned the contacts on it and re-plugged it.
I removed the battery and cleaned the contacts in there with electric cleaning spray.
I re-soldered the battery contacts on the PCB side.
My nexus 7 now goes from 0% to 100% in about 3 hours.
