    I will prolly be told im wrong for saying this, but just let it run down. Use it, though i dont think this kind of battery can be trained, so whatever, its up to you dude.

    i agree but if waiting 8 hours makes it so my battery will last longer i think its worth doing

    Oh it wont be 8 hours. It probably comes 50% charged, and so i dont see it being more then an hour, an hour and a half at most.

    I can't imagine the initial charge being more than an hour or two.

    That being said, I've never charged the battery on any of the iPods I've owned until I ran the battery down all the way, and I've got nothing but exemplary battery life from them. Weird.

    Edit:

    Damn, beat me to the punch.

    Don't ever let the battery run down all the way. Not good for the battery or the phone. But thats just in general.

    In my understanding of the new batteries is that the first charge is not as important as it used to be, but can still make a difference. I usually charge the battery 8-12 hours the first time. However, most devices can be used during their charging time.

    I believe it is generally for Lithium batteries better if they do not deplete to below 40%. However, on MacBooks and MacBook Pros (I believe all laptops) it is good for the battery and for the accuracy of your power meter to 'recalibrate' the battery once in a while.

    On the Apple website you can find a page describing just how to do that (for laptops that is).

    Later, Chris

    Actually, killing it all the way is good for it. That gives you the ability to complete a full charge cycle.

    Do a search for "the proper way to charge you phone" and you will see the real answer about lith ion battery compared to nicad. Don't let the battery discharge all the way and chrage often! Iphone batteries dot not have a memory and it is worse for them to deep cycle charge. I would post my thread on this issue but i can not copy and paste from the phone... Again anyone saying to drain it knows nothing about the iPhone battery!

    Use iPhone Regularly

    For proper maintenance of a lithium-based battery, it’s important to keep the electrons in it moving occasionally. Be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).




    That's taken out from http://www.apple.com/batteries/iphone.html

    So which one is correct? Charging it up to 100% then use it down to 0% at least once a month, or never? I'm also interested on knowing, just got my 3GS and I'm going to let it charge at least 8 hours and then let it go down to 10% at least.

    At a guess, the one from Apple rather than the one from some random guy on a forum. ;)

    More seriously, they are in fact both right: running a lithium battery down until it's totally empty is bad for it. however, the power management system in the iPhone and Mac laptops won't let you run the battery down to the point of damaging it, it will shut the device down first. So, you can safely run the device down until it shuts off to calibrate the battery meter without damaging the battery.

    So it is safe for me to charge my phone up to full then let it sit and discharge down until it shuts off?

    I don't know if it is "required" on the "first" charge, but I'm just used to doing this with all phones, so I figured it would be the same for this one. Is it required, or recommended, or "better" to do this? or It doesn't really make a difference if I charge it to full and let it drain?

    I don't think there's any evidence that it'll make a difference to your battery capacity, but it will make sure your battery meter is accurate. when I got mine I used it for a bit, charged it overnight, ran it down then charged it overnight again. Seems fine...

    Alright, I'll charge it full then let it sit there without a sim card and let it go all the way down until it shuts off, then I'll charge it to 100% again and use it normally.

    Thanks for the help!

    Incorrect.

    Running it down to empty and charging it to full is how you calibrate the battery meter.

    I did that the other night, used it until it autoshutoff.


    Let me tell you ........ the phone does weird things (even though its plugged in) until it gets back over 10% lol
