Thread: Fully discharge?

  1. #1
    Default Fully discharge?
    Is it necessary to do a complete discharge/charge once in a while on your iPhone?

    Or is it bad?

    Apple's iPhone site says you should do a complete charge cycle once a month, and I don't know if they meant to fully discharge and charge.

    They mean fully discharge and charge.

    Everyone says you should do that to a rechargable battery on a regular basis to help the battery last as long as possible. They also say you should not let the battery stay plugged into a charger after its done charging.

    I have NEVER fully discharged any cellphone, or my iphone, or any of the few ipods ive had and NEVER have a problem with the battery.

    So if I summarize what you said:

    It's recommended you fully discharge and charge, but you never did it? :P

    Can anyone tell me if doing this actually helps your iPhone?

    Doesn't Apple's iPhone battery site ( ) claim that we should periodically do a complete charge cycle?

    Maybe Apple doesn't know that their iPhone has LiI batteries

    They probably don't.

    I dont do it on purpose, but Ive done it a few times when Im close to discharging it all the way. It should be done so that you can get the most time out of your battery...
