Why does my IPhone 5 keep shutting down?

canihave · 19-03-2014 9:41pm #1

I have an iPhone 5 which keeps shutting off and will not turn back on until connected to charger. It has switched off at various levels of battery - 42%, 25% etc. There is no logic to it at all. It can happen at any stage. This has been happening now since before Xmas. I have the latest software updated on it. Any suggestions?

A calibration of the battery could help it as your battery indicator could be off.

Otherwise back up your phone, restore from the back up with iTunes.

Has the battery been replaced?
When the phone turns back on is the level % the same as before it shut down?
Have you been using any car charger, or cheap Chinese chargers?

Thanks for the replies. I have tried now restoring it but no use, still switches off.no the betters has not been replaced but yes have been using all kinds of chargers - could that be causing it?

Did you complete the calibration process? Is your iPhone still in warranty?

I have attempted the calibration but I had to restore it first as the battery keeps shutting down before it gets to zero. Since restoring it only got to 0% once and I fully charged up & left in but then next time is just shut off again at 38%. No the phone is over a year old.

I don't know what else to suggest really, it sounds like it isn't a software issue so the battery will probably have to be replaced by Apple. This will cost you €75 + a possible shipping fee.

I'd imagine battery replacement will solve this issue

I'm having the same problem. It will die with anything between 20% and 50% showing on the battery indicator. The problem started after downloading IOS 7.

Well I replaced the battery & so far so good. It has shutdown only at 0%. Thanks for all the replies

I have never known one to go to 0%. My models have always quit on 1% or 2%. Have you done a hard reset ?

He solved the issue by replacing the battery. You would suggest a hard reset if the screen was scratched!

Hard Reset solves a lot of software glitches. Sarcasm doesn't really help.
