    Now I read on other sites about the lithium-oin batteries and how you're suppose to charge them but I want to get your feed back on this. If I charge my iPhone at 20% and then take it off at 100% will I get more or less battery life if I just left it charging over night.

    I could be wrong but for the most part I really don't think it matters. Think it's just suggested to run it down about once a month but I'm not sure that really does anything either.

    Well if you don't plug it in over night when you get up it will have used some battery so it will be less. But if you take it off right at 100% or if you leave it for another 9 hours will not effect the battery life; it will run on a/c power once the battery is charged.

    I see so overcharging it isn't really overcharging it. When its at 100% its all set to unplug? I heard that leaving on the charger over night, you'll have more battery life then taking it off as soo as it hits 100% by the way 3GS is awesome : )
