So my phone seemed better and then all of a sudden I went from 100% to dead in 8 hours. I narrowed the cause down on my phone to the sync option in iTunes (in the computer, not iTunes in the phone.) When I have the sync to this computer via wifi checked and synced. My iPhone dies crazy fast after that. When I uncheck sync via wifi to this computer and sync via cable only, my battery life afterwards is good up to 18 hours of my regular usage. Haven't tested the sync to iCloud yet cause I don't use that option. Can anybody else with the drain see if this is what is happening to them? Maybe it will help. Note: my phone gets really warm when the drain is going on.
