    How and why is this? I personally am worried by this myth/maybe fact because I do not feel that my iPhone 4 is experiencing tremendous battery life, and I did restore it from a backup on my old 3G.

    Now, if this actually were the issue.. when Apple releases the next iOS update, 4.0.1 or 4.1... would this then fix the issue as it's new software being installed to override the old?

    I have the same issue in that my phone's battery life seems to be worse than my 3GS was, and I restored from backup as well. Is this really the reason why?

    I doubt it. I restored from a backup of my 3GS, and I have amazing battery life.

    Well I restored my 3GS from a backup of my orignal iPhone and did have very poor battery life. Restoring the phone as new solved the issue.

    It's never been discovered what setting in the backup causes the issue, but setting up as a new phone always solves the problem.

    I did a restore from my 3G. Although the battery life is better than my 3G, it's not as good as i thought it would be.

    ALSO...do we have to let the battery die out in the beginning for a better battery?

    I'm also getting this as well. After 4 hours of standy and about 20 minutes max of actual use it's already down to 90% This is roughly what I was getting on my 3gs. I'm gonna go ahead and restore it from fresh and see if that changes anything.

    I restored from a backup of my iPhone 2g to iPhone 4 and the battery is not as good as I expected. I don't think it is any better than my 2g.

    Over 7 hours overnight it dropped from 77% to 68% even though I turned off push email.

    Setting up as a new Pune is unacceptable for me. There is key information I need in some apps. Is there a way to restore settings and apps selectively?

    I have notes that I need. Any way to save them without a restore?

    If you connect your phone to itunes then under the info tabs there should be a tick box with notes, when you sync it will save them to your HD. once you've set your phone up as a new one just go back to this tab and tick the notes box again.

    I've just done a restore and after 30+ minutes of use and an hour of standvy the batter is at 98%. Very impressed.

    Thanks for the reply.
    Is this notes in e-mai, or notepad? I will be looking to restore notepad from a backed-up phone.

    I'm losing 20% battery overnight with phone in sleep mode.

    Guess I'll try a fresh restore from scratch tonight and see if that helps.

    I'm really wondering if it will. Seems so hit or miss.

    Resetting all settings will do the trick. Just make sure you don't accitdentally hit reset all content and settings that is directly underneath it.

    It will reset every setting on the phone and leave all apps and their data intact, as well as texts, emails, etc. There was a thread a while ago and it worked for lots of people who were suffering from battery drainage as a result of upgrading to a new phone or upgrading to a new software.

    I just tried the resetting and it apparently didn't work.... I'm going to have to try a fresh "install" tonight. But from when I opened this thread and read the posts my battery was at 72% as I'm typing this and sending it, it's at 67%...

    They said try restore from new tonight. Then test overnight. If same issue I'll get a new phone. Restore to new should fix it they claim.*

    My battery us just sucking juice.

    I used a back up of an iPhone 3G on my new iPhone 4 and to be honest I haven't been overly impressed with the battery life. Overnight it drops about 9%, so from 100% full charge to 91%. I know this isn't as bad as the others, but still I wasn't expecting it to drop this much. When on calls the battery life starts to drop dramatically, to the point where I'm constantly watching the percentage go down. Can anyone confirm how fast there battery percentage is going down when on a call, for example, 1% per minute? It's just to confirm whether or not I should do a restore to new on my phone as well and therefore lose all my back up settings :(

    On another note, but the same issue, has this restoring from a back up causing bad battery issues been confirmed? I haven't come across it anywhere other than on this particular post.

    Just what the rep told me. Not sure if technically "confirmed" or not.

    settings>general>reset>reset all>Yes

    then let it drain to about 10% and charge it fully

    I am assuming this would also reset things like stored WiFi networks/passwords and things like that ... wouldn't it? Any way of knowing exactly what it will and what it will not reset?

    Data and media are not deleted. Everything else is reset. So passwords for WiFi networks and so on will be deleted and need to be re-entered.

    I did. Rep said it wouldn't help. But after I did it I've lost 27% still in about 20-25 min of safari use.

    Just unacceptable.
