    My iphone has a issue.

    When my phone gets to 100% while charging it doesn't switch income to the "fully charged" symbol it stays on the lightning bolt which indicates its still charging.

    Does that mean its still trying to push more into the battery at 100% ( which would damage it ) a hardware issue.

    Or is it wrongly indicating that its still charging? Which would be software related.

    Keep charging it until it changes from the bolt symbol to the plug symbol. This may take 30-60 minutes. This is happening because your battery isn't fully calibrated yet. It takes 3-4 full discharges and full charges to calibrate correctly.

    It doesn't change.

    If I go to sleep at 11 with 70% charger, wake up at 7, it'll still say 100% an still charging.

    It may be letting the battery discharge a bit when it gets full. I think my third-gen iPad does the same thing when the battery becomes fully charged. It discharges a bit and then charges back to full and repeats the cycle until you unplug it.

    dont worry, it (may) happen during the initial phase.
    make sure u stop it. after a few charge cycles, it shouldnt happen again.

    if u dont have time to (like u charge it when u're asleep): i would suggest, u plug ur iphone, switch it off (turn it off, not put it to sleep), and let it charge the night.

    Thanks for the advice.

    I think I'll charge it to 100 when I'll still awake, turn it off when I sleep (and unplug) and hopefully it'll stop soon so I can go back to my normal schedule.

    Don't worry about overcharging. The phone won't let that happen. It's working exactly as its supposed to.

    I got my iPhone over the weekend and the same thing is happening to me where it's at 100% for a few hours but it's still the lightning bolt sign. I've already drained the battery once, but should I do it again?
