    I upgraded to 4.0.2 yesterday, and I already thought my battery life on my 3GS sucked. But OMG. I had to put this thing on the charger four times to get through the day today.

    I just took it off the charger a bit ago.

    85% remaining
    28 minutes of usage
    54 minutes of standby

    Is that normal? What do you guys think?

    Thanks,
    B2TM

    Not really since my first post it is down another five percent. I even rebooted to make sure everything was "off". I hate this multitasking feature. It doesn't work worth a poop and seems like it kills the battery. Wish I could downgrade to os 3

    Yes, things running in the background will take up some battery life. How did you reboot the device?

    I think that life of the battery means the time your iPhone will run before it must be recharged, and always try to make sure that your iPhone has the latest software from Apple, as engineers may search new customs to optimize battery performance.

    Well with heavy internet usage and games, I'll typically get somewhere around 5 hours of usage.

    Mine seems pretty bad on my ip4. Although it is jailbroken. I only get about 4 hours max of pretty intense usage like playing games gps etc. Mine seems to lose quite a lot while on standby as well, I can't figure out why, I have no push notifications and mail set to fetch hourly.
    Pre JB I could last 3 days without charging.

    The thing that people forget is that sometimes stuff just gets %*$#ed up.

    My wife's 3GS started running out of juice after 3 or 4 hours last year. No real reason for the timing. Turns out the mail program got bonkered and was constantly checking her work exchange. Restoring from backup didn't fix it. A fresh restore did.

    It sucked but it didn't have anything do with a particular OS version or some new phone feature or what network we were on...

    Humans love paterns and corelation. So much so that our brains try to invent it when there's actually nothing there. But sometimes there's not a link. Not everything that goes wrong is because of the newest software. If it was you'd see a lot more posts about it. (Like, say, the proximity sensor issues.)

    Sometimes you just have to restore the phone from scratch, say "oh well, that sucks," and stop worrying about finding the cause. Often the search takes longer than the cure and you still don't end up with any answers by the end. Such is the world of computers.

    1. Set Auto-Lock to 'Never'
    2. Place brightness to 1%
    3. Leave iPhone on desk for the day
    4. Come back and screenshot alleged 'amazing' battery life

    I dont. first of all if he charged it during the use then the phone would say so. Also I used to get similar statistics on 4.0.2. 4.1 seems a little worse for me but I havent done a full cycle yet. When I had 4.0.2 i used to get about 12-13 hrs of standby along with 7 hrs of use and I would still have like 40% battery life. This was after it was calibrated so the percentage was pretty accurate.

    I think the battery time is pretty good. One charge usually lasts two days. Using BT-headset and streaming from the web when I go to work (35-40mins) each morning, full sync to Google Apps with mail, contacts etc. Some phone calls, sms, mail, Angry Birds, surfing etc.

    My current stats are as follows;

    Usage: 5 Hours & 44 minutes
    Standby: 1 Day, 7 hours.
    Battery level: 12%

    I have GPS on all day long, wifi mainly, phone calls, sms, and games. This is almost 2 days of use. So whats my problem here? What am I doing wrong?

    GPS drains a LOT of battery
