    Two days ago I updated to IOS4 and the battery drained too fast!!!!
    In the night while it is in stand by mode the battery drops from 80% to 15% doing nothing for 6 hours..... I turn off notifications.... and the problem persist...

    Today I turned on "Airplane Mode" when the battery was at 15%......
    this switch off wifi...but you can turn on it again in this mode....
    and two hours later .... it was at 15%.... no drop!!!
    and the wifi works like before, i received my email while it was in stand by....as did before with IOS 3...

    I recharged to 100% and now 4 hours later the battery is 95%..
    that saves alot of battery!!!

    Why they put "airplane mode", isn't more correct "Persistent Wifi" ON/OFF...
    O "Save Mode"?

    I whish it works to you too!!! :D
