    I am hoping someone can help me figure out what is going on. I was getting 6 hours or more usage for screen on time, and now my battery is draining pretty fast on it's own. Here is my battery usage from today with very little use. Just 1 hour of screen usage. Android System seems to be the biggest issue. Any ideas what I can do with that?

    When you got 6 hours of screen on time, was that with pretty much continuous use, or was that also with plenty of idle time mixed in?

    When it got 6 hours, it was with a lot of use of course.

    Nope, 4-5 bars most of the day as shown in the screen shot. I haven't left the house so that signal was the same.

    I just wiped the cache partition. Will see if that helps any.

    Try look into bluetooth/NFC
    I see that you use it, maybe the battery issues are there..

    It could be a rogue app.

    Perhaps put the phone in safe mode which turns off all your downloaded apps and leaves the stock ones alone which can help to determine if an app is causing this situation.

    If it was a rogue app it would be showing up under the usage pic I posted.

    That's if it's being reported correctly by the phone.

    I mentioned Safe Mode as this is part of the Process of Elimination processes people use to self help diagnose.

    Maybe a Samsung Experience Store or Service Centre will be able to help you further via a diagnostic on the phone.

    Thanks, but what does that exactly wipe? And I'm assuming its doesn't delete any information on my phone?

    It gets rid of old redundant caches.

    It's designed to not delete your own info like a factory reset does.

    I forgot to mention..go to device maintenance and upper right hand corner hit the notepad icon and see if any apps crashed maybe might find something there.

    Had one app in there for my state farm app. It wasn't recent though. It did it 4 times on the 25th, but hasn't since. Here is a screen shot of todays usage after making a bunch of adjustments. Seems to have helped it.
