I had the same issue an update or two ago on my Galaxy Note. I googled it, did whatever a handful of articles suggested, and my battery has been fine since. I'm sure if you do a google search, you'll find some helpful hints out there.
I'm not trying to be a smartass here, but I acknowledge it could sound like I am...I simply don't remember exactly what settings I adjusted, and since we have different phones, perhaps your suggestions would be different anyway. Good luck to you!
