my iphone 3 is only 4 months old and even with all the apps closed other than mail, it only has 25% left after being fully charged for 3 hours.   I let it completely die last night and then fully charge too.


Any suggestions

iPhone 3GS, iOS 4.3.2

    How do you know all apps are closed? (hint: not appearing in the Quick Launch ribbon does not mean an app is closed). How long does it take to get to 25%? Do you have an Exchange email account? If so, how many messages are in your inBox, how many contacts, and how many calendar entries do you have in the respective apps? Do you play multiplayer games? Do you have the Facebook app? Do you have news apps (AP, NY Times, WSJ, etc)? Do you have Twitter? What about Yahoo Messenger? Google+? Other apps that show up in the Notifications list in Settings?

    That's clearly not normal. But your observation about mail is important; the mail app may be stuck. First, press HOME twice and kill mail, like you did the other apps. The reboot the phone by holding HOME and SLEEP until the Apple logo appears (10-20 seconds). Then launch mail and see if it is still constantly updating. If it is go to Settings and turn off the mail account, open mail briefly, then reboot again. Then turn mail back on. If it's an Exchange account turn off Contacts and Calendar also, and launch each of those apps briefly before rebooting.


    This should fix it. Normally I would suspect heart radio and pandora, but if you killed them they are not the problem.
