The tablet will not charge past 84%. It's less than a year old and approximately 6 months ago it started charging very slow with the original charger. It would get to 100% but it took all day and the battery would die within 2 hours when it wasn't on the charger. I bought another charger from Verizon and it worked for maybe 6 weeks and then it completely stopped working. Now using the charger that came with my Samsung phone and it took 18 hours for it to get to 84%. I charged it for additional 12 hours and it would not go past 84% and this is what the tablet completely off. I followed all the troubleshooting methods that are listed on the Verizon Wireless page including changing it to safe mode and keeping the tablet off of when not in use which is what I had done before. Is this just a factory default or is there any other way to fix this issue?
