Is there a solution for preventing battery drain on the 5s after the iOS 7.0.6 update? I have tried a hard reset, removing Outlook email account, and closing all apps and turning off Background App Refresh.
This question was answered by updating to iOS 7.1. I've since turned all  the features of the phone back on (e.g., background app refresh, notifications, use my location, all the processes that I tuned off trying to troubleshoot) and my phone just lasted three days with normal use.
