My iphone 4 battery often drains too quickly, and I wonder if it has something to do with my Mail App.

When my phone is not playing nice, it drains at least 20% overnight while on Standby, and from 100% to 30% in around 6 hours when I use it during the day. I found a fix (http://discussions.apple.com/message.jspa?messageID=11775150) that basically says to wipe your mail account and set it up again.

This fix works, but only temporarily for me. I find that I have to keep resetting my mail every few days to get back to "normal battery" where it barely drains overnight. I only use one email account (gmail) -- could there be something going on there?

Oh, and when my battery drains fast, nothing changes when I turn off WiFi, notifications, push, etc. I usually have my mail refresh hourly.

Has anyone had this experience?
