Ok so I got the Note 10.1 2014 edition as a christmas gift. It is working fine. The only thing that is wrong with it is the battery is dropping from 50% to like 8% in a matter of 5 min. Or when I power off my device at say 70% and turn it on, it is at like 3%. I do not understand that a battery can just drop like that. Should I return it? Try to fix it? What should I do? Please Help!!!!!!! Thanks in advance
