I just went thru the same problem with the Nexus 7. Everyone thought it was a software issue, it turned out to be that the USB mini port had become wide because of repeated insertions of the power/data cord. If you have a USB mini port, it could be your problem.
Hi there! I am having the same problem with my iRulu AX107, I know it is chinease but it works fine. My problem is the battery charges but when it reaches 10-20% it makes a jump to 40-50%. You will see in the images below. It does the same when I am using it, for example I put a youtube video when 80% of charge and let it be until 4%. It took just 90 minutes to go through... What happens to my battery? My tablet was bought only 3 month ago!! I tried using both chargers, the real one that comes with it (1.8A) and the USB cable from my samsung (1A).
I put my problem to avoid opening a new topic, I think it is more or less the same
