Something improved the battery:
I turned off push mail...BUT i am not understanding why push mail is using so much of the battery.
Push Mail was set ON, but set to "manually"!!!
Can somebody explain the difference between "PUSH MAIL ON + MANUALLY" and just "PUSH MAIL OFF"?

I have to note something interesting about "USAGE":
I was using the App "RadioAlarm". The App notes that RadioAlarm, if not closed, over night uses much of the battery. Thats ok. I dont close the App. It uses 15%-20% of the battery over night.
Really noteworthy is this:
"USAGE" takes the whole night to its calculations. RadioAlarm stayed in the background. Everything else was off. In the morning i had 10 hours of usage with 80% of the battery.
I really wonder when and how the usage-score is collecting data. It would be ridiculous if usage is numbering Apps from the background as true usage of the iPhone. If this is so, something is going terribly wrong and the Usage function is selling us a better numbers then it should be.
How you guys think about it?
