    Sorry for the newbie question!!!!!! I just activated my new iphone (love this thing), and see that it already is fully charged. Do I let the battery run all the way down before charging it, or do I charge it first? Thanks!

    Since the battery is Li-ion, it shouldn't really matter. For good measure though, I would:

    1. fully charge it
    2. fully discharge it
    3. let it sit powered off overnight
    4. fully recharge it

    Older Ni-Cad batteries had a recharge memory problem so doing a full drain would establish its full potential.

    true, there is no memory ... so i wouldn't do any of that... in fact, letting it fully discharge might do more harm then help.

    I just got home and have been using the iphone all day and it's about half charged. So I shouldn't let it run all the way down? I'm not familiar with what kind of harm can be caused by fully discharging it, but if there's any chance of it, I'll just recharge it tonight and continue recharging it every night regardless of how charged it is, like I did with my old phone, the Motorola Razor. Would that be OK?

    Again, thanks for helping a true newbie out!

    IMO you're getting some bad advice here.

    Lithium Ion batteries detest being fully discharged. There is no need to do that. Li-ion batteries do not exhibit the "memory effects" that Nickle metal hydride batteries of yesteryear did. On those old NiMH batteries, you did need to fully discharge them periodically.

    NOT SO WITH Li-Ion. In fact, you do more to shorten its useable life by discharging them completely. :eek:

    Do NOT ever fully discharge a Li-ion battery, it will shorten its life.
    The best advice on how to use a Li-ion battery, is just using it how you want. Charge it whenever you want, just don't let it discharge completely.
