    What can I do to increase battery life? I watched about 2 hours of video, and surfed (WiFi) for 30 minutes. After that, I only had 1/3 battery left. What can I do to increase battery?

    Thanks!

    Various settings I have:
    Auto light
    Push data
    Wifi on
    3G on

    Sounds like my ver 1.1 ipod touch

    If apps are running in the background that you don't need, be sure to close them.

    Turn Wifi and 3G off unless you don't need it.
    Lower the brightness and turn autobrightness off.
    Get your mail manually instead of pushing it.

    I turned location services off from the settings and I am getting decent battery with the rest of the settings like yours - no big deal the gps will turn on if a program needs it and you assent.

    I take it you haven't read all the complaints from developers... There are no background apps outside of those to make the phone actually function. This is why IM and other persistent-connection apps will wait until later this year when Apple turns on the Notification Server.

    The most you can really do short of disabling the phone's essence is check mail manually.

    What exactly does the location services do?

    Thanks again!

    Are you sure this is the case? I may have to give this a try myself, as I haven't been too impressed with battery life yet either, and I've got 3G turned off. Interesting.

    I know what you mean. I swear I'm only getting 4 hours for video.

    Has anyone anything about this happening in 3G iPhones? How many hours do you guys get with video. So far though, battery on WiFi has been good!

    IIRC, you need to let the battery go through a couple of charge cycles before you see the true capacity of it

    Thank you.

    I was wondering if that was true. Everytime I charged it, the battery seemed to improve.

    The GPS in the location service seems to REALLY chew the battery bad. The big problem is that all the various apps that use it ask if they can turn it on, but they don't turn it off when you switch out of the app... So once it's on, it's ON unless you go into settings to turn it back off.

    They really need to add an option where you can independently turn Location service (the cell triangulation portion) on/off vs the GPS (sat nav portion) on/off. For most things, the triangulation is good enough.

    Turn Wifi/3G off until you need it.
    Have mail check on manual.
    Auto-brightness off.
    Turn off any EQ's on the iPod, this uses more battery as well.
    Turn Location Services off.
    Turn Auto-Lock on, or try to keep the screen off when you don't need it on.

    All I could think of, but let the phone go through a few cycles and you'll start to see it's true battery life.

    Email Steve Jobs about this, that's a great idea.

    As others have said, we all knew the battery life wouldn't be great and Jobs admitted such even during the original iPhone where he said that he went to Edge because of the strain the 3G would put on battery life

    Well, that just means people need to learn to switch on/off the 3G connection to save life

    Calibrate your battery.

    I agree. My phone isn't even 24 hours old yet, so I would be hesitant to quote any run time. I assume everyone else's phone can't be more than 48 hours old yet, so I think we need to give this some time.

    I am also curious about the effect of Location Services though...

    And how do you do that to Lithium Ion batteries....????

    *WARNING.... THIS IS A LOADED QUESTION....***

    Don't be stupid....

    It's ironic that the iPhone 3G has about the same real battery life as the 3G phones Jobs used as examples of why Apple first used EDGE.

    The reason the first iPhone didn't have 3G, was simply because it would've cost more, both in parts and in user data plans, and Apple couldn't have that.

    The reason it got 3G, was because sales needed a boost, not because the technology got much better.

    Anyway... battery... sure wish they'd designed the insides differently, with the battery against the back case... so an extended battery could be swapped in.

    How about you don't be stupid?

    Lithium Ions are beneficially because of the IC circuit attached to the battery. The IC Circuit controls the voltage variations of the charged target battery. That should be set to its high peaks or close so that.

    But over time or over a bad charge like lets say FIRST CHARGE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! The circuit will think its of lower capacitance that it really.

    hence why it recommend to go though a full charge up (with interrupts) and charge down) to calibrate your battery. Then afterwards.....You don't want to let your battery go down a certain voltage threshold or else the life cycle of the battery drops exponentially. I've been studying battery effects for years and done tests on them.

    ...

    your move home spice.

    gotta treat the iphone battery as you would any laptop battery. let it charge to full capacity. use it until the battery dies completely. charge it again to full capacity. that will help get the battery to its true capacity.

    as far as an extended life battery, i'm sure someone will come up with one that fits sooner. newer tech is my likely candidate for this.

    when should you do this? or how often? i've charged my iPhone fully twice.

    (once when it got down to 20%)
    (and once when it was like 60%)

    my iPhone battery doesnt seem to be all that great.

    should i go ahead and let it die and fully charge tomorrow or wait? or does it even matter?
