6.1.1 Battery Drain fix
After updating my 4S to iOS 6.1.1, my iPhone's battery would drain completely in about 4 hours (compared to lasting about 20 hours with 6.1).
This was related to the Exchange account on the phone and the calendar bug in the previous iOS 6.1.
Here's what I did to fix it.
- Removed Exchange account from the phone.
- Reset Settings back to factory default (did not clear all apps and data)
- Had my exchange administrator disassociate my device from exchange
- Rebooted phone
- After 1/2 hour I added my Exchange account back on my phone
Battery consumption went back to normal.
