I have had my Galaxy Tab Pro 8.4 for about 4 months nw. At 1st when i charge it from 5/20% back to 100% fully charged it would of had no problems charging. But now most of the time i charge it it goes from 5/20% and it gets struck on any number like 25%, 40%, 67% , 92% and never goes back to 100% fully charged unless i replug the charger back in or restart the Galaxy Tab Pro 8.4 and after it charges again. I don't know why this it is happening, I had never had this problem on my old Galaxy Tab 2 7. How do i fix this faulty battery and will it get worse in the future as i be planning to use Galaxy Tab Pro 8.4 for a least 2/3 years. Should i be worried? On a side note: i haven't completely drained the battery to the full.
