Samsung Galaxy Tab Pro 10.1

Hi everyone.

I have a Samsung Galaxy Tab Pro 10.1 that I received as a gift in June 2014 🙂 and after about 2 months the battery started giving me problems 🙁
Once fully charged, in maximum an hour it’s at 30% and is dead within another hour. This is while surfing the net and using other apps. No youtube or videos.
I’ve reset my tablet many times though that does not seem to help much.
Any ideas what I can do to solve my battery issue without actually changing the battery? lol
Thank you in Advance
