how I think I solved my iphone 4s sudden battery drain

The original thread I was posting in appears to have been closed, so I am writing this here in case someone else is having the same issues.

Since May I have had intermittant periods where my iphone 4S would be out of power in about 5 hours after a full charge even if I was not using it. The usage statistics (settings:general:usage:time since last full charge) would show that usage and standby were usually exactly the same, and both were the time since I took the phone off the charger. I tried adjusting settings, hard resets, resetting network settings, etc, various things that didn't seem to help. Then I found this Apple support article (duh!) that seemed to help http://www.apple.com/batteries/iphone.html. When I went through this article step by step I found that under "fetch new data" i still had the global setting for push "on" although I had turned that off at every apps individually (I thought), and one of my gmail accounts was still set on "fetch" although overall my mail app was set to "manual" fetch.

I turned both of those off and now my phone is back to making it all day with moderate usage. I am still curious/concerned that my usage and standby are still almost the same... usage will show as maybe 1/2 hour less than standby at the end of the day.... but actual battery life seems to be greatly improved.
