Battery drain after updating to iOS 5.1.1

Question

After doing the update to iOS 5.1.1 the phone is getting hot "warm" near the processor and the battery drains about 1% per 10 mins in standby and 10X when running an app. Meaning that the phone will run about 6 hours when it used to run for 48 hours on a charge. When putting the phone in airplane mode battery life appears normal. Following others that have reported this issue, I've done a Reset All Settings and two Erase All Content and Settings then restored from back up. Unfortuately what worked for others has not worked for me...
Took the phone to the Apple store and was told by the genius that there are no issues with the update and that location servers were to blame. Explaining over and over and over again that none of those settings have changed and that the only thing that changed was the update I got no answers, just more frustrated.
Currently I have all location services off and wifi off but still have the same problem.
Looking to either find the magical reset sequence that others have has success with or just roll back the update.
Help.

Close all open apps by double-tapping the home button, then swiping up and off the screen with the app window (not the smaller icon).
Reset your device: hold down the home button along with the sleep/wake button until the screen goes black and you see the Apple, then let go. (No data loss)
