[Galaxy Tab 3 Q&A, Help & Troubleshooting] gsrac3r:
I have a P5210 running this ROM: http://xdaforums.com/showthread.php?t=2590713 Pimpdroid for Tab 3 10.1

Prior to that ROM, on a different one I was averaging 6 hours screen on time with power saving mode active. I only use my tablet for browsing the internet, Skype calls and emails. I do not use CPU intensive programmes, and most of the game my Tab is on 800mhz according to BetterBatteryStats. I have my screen brightness on about 15-20%.

That said, I still cannot figure out why I am losing 63% battery for a little over 2.5 hours screen time. This means that for a full charge, I will only get 4 hours 10 minutes of screen on time. Other users have said they get 8-10 hours, Samsung states 10 hours...what am I doing wrong?
