I have an iphone 7 256gb, the problem I have been facing is that my phone battery dies at 3% and during night on standby mode my battery drains alot like 13 14%. can anyone tell that is my battery damaged or is it normal?

Hi,

Sounds like there could be a problem with your battery. To test this when the % goes down lots do a hard reset on the phone and then when it's back up has the % changed? has it gone back up?

The best bet would be to take the phone to an apple store to run tests.

Hmmm...once the battery gets as low as 3%, it won't take much more use to make it die pretty quick anyway. Particularly if you are doing things which require the screen being on.

Overnight, if the phone is on and not being charged, and receiving notifications, then I'm not convinced a battery drop of 14% is that remarkable either. Personally, I usually connect my phone to power overnight so that I know it will be fully charged in the morning.
