Thread: Iphone 4 low battery because of 3G?

    Default Iphone 4 low battery because of 3G?
    Hi everyone,

    So I got an iPhone 4 last week, and while its great, the battery life dies a lot quicker than even my 3G which is 3 years old.

    So I did a google search and it seems several people are having this problem. One person claimed that people at Apple told him that if you had a iPhone 3G before, and backed up everything onto the iPhone 4, this is the cause for the poor battery performance

    Is there any truth to this? has anyone tried this and had their battery performance increased?

    I finally have my iPhone 4 the way I want, and I would rather not set it up as a new phone after a restore, and have to manually put all my photos, notes, etc back into the phone

    Thanks for all your help guys, really appreciate it!

    just updated to 4.3.3 and its jailbroken...

    its not that bad... but if I ever use the phone more than normal, it will definitely run out before the day is up

    MS is mobile substrate.
    You can enable/disable ms addons through SBsettings( look for it in cydia)

    Some ms addons are always running that don't really need to be. I.e. MyWi, Dreamboard, safari download manager, etc.
