    what is the best way to achieve optimal battery life? run it all the way down, then charge or charge it fully before use?

    Strangely, the manual doesn't say. I just looked through the one that came in the box with iPhone. Maybe it talks about inital charging on Apple.com? :confused:

    What I can't figure out for the life of me is why Apple didn't include the full manual inside the box of every iPhone that they posted on their website. Was this a HUGE oversight? Can you image how many non-enthusiasts who buy this phone that are going to be super confused about all its functions without the manual!?!

    To calibrate your battery:
    1 Plug in the power adapter and fully charge your MacBook battery until the light on the
    power adapter plug changes to green and the Battery icon in the menu bar indicates
    that the battery is fully charged.
    2 Allow the battery to rest in the fully charged state for two hours or longer. You may use
    your computer during this time as long as the adapter is plugged in.
    3 Disconnect the power adapter with the MacBook on and start running it from the
    battery. You may use your computer during this time.
    When your battery gets low, you’ll see the low battery warning dialog on the screen.
    4 Continue to keep your computer turned on until it goes to sleep. Save your work and
    close all applications when the battery gets low and before the system goes to sleep.
    5 Turn off the computer or allow it to sleep for five hours or longer.
    6 Connect the power adapter and leave it connected until the battery is fully charged
    again.

    Replace iPhone for MacBook.

    you should NEVER let your battery die as this causes STRAIN to the battery, sometime if you deplete the battery totally it wont even take a charge after that.

    the only reason why you would cycle a battery (drain and charge) is so you can calibrate the charge ciruit inside the cell.

    any other time, keep it charged, not calibrating the battery wont hurt it at all, the power meter on your phone maynot be 100% accurate thats all.

    also charging the battery in your car while its hot, or charging it in a hot place in general will kill the battery in less than a year. try to keep your iphone COOL all the time. heat is what kills batteries the most next to cycling it.

    I too would like some more feedback on this. I know the basics of the rechargeable battery but I want specifics for the iPhone :D

    Just go ahead and use the iPhone.

    No charging required.

    You're not supposed to run it all the way down.

    But then again, the software will prevent you from running it down completely.

    There's always juice left in the battery when the phone/notebook shuts down.

    Just don't let it sit around for days with drained battery.

    No "fully charged" confirmation?

    The thing is, with my iPod, when the battery is fully charged, the screen shows the battery cell icon full and says "charged." As far as I can tell so far, the iPhone doesn't have any text with the battery cell icon to state that the battery is fully charged, so I don't know when it is, or if the graphics just make the battery cell icon full when, in fact, the battery capacity is just >95% charged, or whatever.

    But maybe Apple omitted all this info and feedback because it doesn't matter, and we are just being overly concerned.

    According to the user manual, the iphone battery is fully charged (100%) when the really small icon on the top right changes from a lightning bolt to a plug. Check out the iphone user guide and do a find on the word "charged".

    The never ending debate on whether to cycle a battery or not... I've heard/read so many conflicting opinions on this it's crazy. Let me share what I've heard and maybe someone can confirm if any of it is true:

    - Batteries now-a-days do not need to be cycled. I don't know the correct term for new batteries but apparently only "older" batteries needed to be cycled.
    - iPod doesn't need to be cycled. It says so on the Apple Support pages.
    - I would assume the same logic applies to the iPhone (I'm assuming same technology, battery type, etc.)
    - For Apple not to have included this info in the small manual that comes with the phone you have to assume it's a non-issue, right?

    Those are just some thoughts... I could be totally incorrect on everything I just typed up there just an FYI.
