After the last update for my phone I have been experiencing around 10% battery drain an hour with moderate to low usage. I have already done 2 factory resets and formatting my SD card. I have disabled GPS, WIFI, Global access, Google now and everything else that i can find that could cause a drain. I have even gone and disabled/uninstalled all apps that I don't use. That didn't fix anything. I started to suspect that my battery was bad. Ordered a new from Samsung and charged it all night on there spare battery charger before using it. It actually seems to be draining even faster, after 45 minutes I was already at 88%. During that period I sent about a dozen texts and checked email and the weather. So I don't believe its the battery. Any suggestions to help resolve this will be greatly appreciated.
