    After upgrading to 3.0.1, for the 1st time ever in my JB history, I experienced excessive battery drain. I had battery percentage enabled in SBSettings.

    Here is a fix for 3G phones which has made an incredible difference for me

    1) Turn off %battery in SBSettings
    2) Open Cydia and add this source ----> http://apt.iphone-storage.de
    3) After repo is added, install asBattery
    4) Reboot phone ..... a respring will not work !
    5) Open settings/general/usage (located below "about" selection)
    6) Toggle on Battery Percentage
    7) Re-spring

    Enjoy longer battery life !

    I hope this helps some of you out.

    This work for anyone else?

    What exactly does the asBattery app do to prolong battery life?

    I am suspicious, but optimistic.

    hmm, charged last night, used a bit today at work and my battery shows 75%

    not a huge increase, hmm maybe a tiny bit difference.

    uninstall asBattery too.. u'll get a lot longer battery life.
    for some reason, showing the battery % drains battery like there's no tomorrow.

    and i wonder if that was the reason it wasn't included in the official 3.0 version for the 3G.

    or could the % be rounding down or something?

    maybe its just the % thats off, and turning it off give us just the battery and that itself its hard to judge since it only moves down in sections.

    i dunno, just a thought.

    When I installed asBattery on my iPhone 3G, the percentage was 3 percent off compared to the app Free Memory's percentage. I installed "Show Battery Percentage" from the repo http://iphone.org.hk/apt and it was as accurate as the Free Memory percentage.

    Edit: For some odd reason, the battery percentage on my 3GS is 3 percent off from the Free Memory app as well!? I tried installing "Show Battery Percentage" on it even though it has the toggle built in, and it fixed it. Bizarre.

    Results for my 2nd day using this:

    Unplugged phone at 8:30 AM from charger

    At 10 PM tonight, battery still at 56% after full days use.

    That is much better than the results I was getting with SBS settings.

    Why does it make such a difference in battery life? I have personally never used SBsettings, and have only used asBattery. So I can't compare, I just think it's weird that it makes a difference.

    Most everyone seems to report that SBSettings % battery toggle drains the battery.

    I never had any battery problems until I JB under 3.0.1.

    I have since gone back to 3.0 and JB, but still experiencing some excessive battery drain.

    seems like this is all mostly in your heads than anything. i use sbsettings and show the battery percentage. i am not getting any weird extra battery draining issues on my iphone 3g at all.

    I only know that when I installed asBattery, the following day by 1pm I was down to 50%. The following day without asBattery, having used roughly the same stuff on my iphone, by 1pm I was at +80%

    Yes, toggling on %battery does drain your battery faster than not using %battery.

    But for me, I get less drain with asBattery than I did with SBSettings.

    Others may not have the same experience.

    Good luck.

    im noticing a small difference....however, i will tell you guys something that gave me a big difference in battery life.

    I know that there is people who dont believe in this but, it really worked for me...YMMV.

    A friend suggested that i drain the battery COMPLETELY. I thought to myself, well this cant be good for a li-poly battery...i could of sworn people have always said that you not supposed to drain it fully.

    However, friend bet me that if it broke my phone in anyway, he would glady purchase a replacement for me. He assured me that he has done this when he had the iphone and it helped alot.

    Anyway, turned the brightness up, turned everything on that i could...played a few games and really beat it up to drain to to 1%....i got the warnings at 20% and 10% from the phone itself...however, the last 3% of the battery took almost as long to drain as 20% down to 4%.

    Finally it died on me and not turning on with the button....i plugged it in (little empty red battery pops up for about 2mins and then it turns on again), turned it off again, and let it charge ALL night with the phone off.

    This morning took the phone off the charger at 8am, browsed a few sites (check NCAA football poll, GO GATORS #1). Listen to the ipod for about 45mins give or take, sent a dozen or so SMS...its now about 3pm and my battery is showing 87%.

    Hope this helps.
