HELP!!! Bear with me here... I NEVER been on a website on my Nexus 7 that drains... ie. FaceCrap or a messenger app, etc. until a few weeks ago, for the first time, I logged into Hangouts to chat with someone and a site I am on where I went into their chat area. Never did that before. I knew that would drain the battery a bit. Fine.
After that, I noticed my battery draining. I decided to retstore the tablet to factory settings and upon reinstalling it tacked on 5.1.1 I went back into the site chat a few times and did not notice a huge drain. Then it started, and since then I did not go back to that site... my battery is draining when I am on WIFI at home and it is plugged in!!! When I am on Kindle and the WIFI is off, the battery remains stable if it is at 100%... and also stable when it is lower that 100% never increasing to get to full charge.
I cleared history, cache, running apps, apps in cached processes. I seriously only use my tablet for Kindle, news sites and Twitter. Bluetooth is always off as well as location. I do not leave the WIFI on when I am not in Chrome. I do not have an HD moving screen or even a clock or other running app on my front screen.
I bet I am leaving something out that someone will ask me about.
With all that mentioned, I was thinking of restoring it again. But still, WTF? There are so many people who use draining things on their tablet & I can see where they would have the problem I am having. I should also mention that it takes an over an hour to charge the battery from 80% to full, with WIFI shut off and not using it.
I have never abused the battery or let it ever run down. I believe the lowest I have ever seen it run down was once at 18%. I do not let it run down lower than 30%. I am more than willing to restore it again, I do not have anything stored on it where it would be a pain to do so.
