Is it bad to leave your iPhone on at night but not charging?

I've heard your not supposed to leave it on the charger at night so what if I just charge it to a hundred and leave it on at night. I want to do this for an alarm. Will leaving it on at night hurt the battery in the long run? It dosent bother me if it loses a little battery but is it bad to keep it on at night or is it okay as long as it's not on the charger?

Yes it's perfectly ok to leave it on all night without a charger. It's the same as leaving your phone on all day.

I actually leave my phone on the charger all night, every night and have not had any issues in the 2 years I have had it.

Yes. Charging it overnight damages the battery and it is one of the main causes of a shorter battery life.

and it's best to keep the iphone turned on but locked.

this is because the ions need to kept active… Both within the battery and the device.

apple recommends that you "use" the iphone every day to keep the phone at work so that it does not get slow…

go to the apple site on battery management + lengthening battery life.

You can leave it on the charger at night. In fact it is usually recommended so as to have a proper charge for the morning.

No leaving it on will not hurt the battery… Since its usually on anyway.

  • Why is it bad to leave your charger on? Like for example, you have to take your iPhone out when it reaches 100%, or only charge it when there's little battery left. My friends and family have all told me to take it out once it's fully charged instead of leaving the charger plugged in, and I do take it out once it's at 100%, but I've always wondered why.
  • Should i leave my iphone to charge all night because its turning on at all? My iphone won't turn on and i know before it turned off with like 2% battery so should i leave it all night and maybe hopefully it will turn on? 15 minutes ago - 4 days left to answer.
  • My iPhone has been charging an entire night but won't turn on? It has water damage but was repaired with minor issues as expected. The last two nights its taken longer and longer for it to charge to turning on. Last night is the worst because its been charging for over 8 hours and hasn't turned on. AND YES the lightning bolt' symbol is on. Anyone have this prob? I'm worried it will just never turn on again? Have you heard of this happening? Yes I've tried the soft power down holding both buttons doesn't do anything to turn it on
  • Is only charging your iphone with your laptop bad for the phone's battery? I don't have an outlet by my bed so I use my laptop to charge my phone, but I was just wondering if it was bad for the battery life since it takes slower to charge with the laptop
