iPhone 4S random shutdowns?

Can anyone explain to me why my iPhone 4S keeps randomly shutting down during random parts of the day? This is the third time it's happened since the day I got it on its release date. I don't think its overheating because its just in my pocket and its not hot outside. Could I have possibly not closen specific apps correctly and so inturn eventually shuts off to turn the apps off?

iOS 5

My 4s died 2 times in 4 days since I bought it. I restored as new.The result was 2 shutdowns and few reboots in about 3 days. The diagnostics reviewed 5 panic.plist entries.

I bought the phone from a local wireless carrier and according to the protocol I received when I brought back the phone to them, they can keep the phone 30 days for repair.

If the statement about the panic.plist entries is authoritative, can it be used so I can have my phone replaced with a new one faster?

I'm almost certain that I've seen it mentioned on these forums that if you get the iPhone from a network providor shop, it is still possible to go to the Apple Store and have them replace it. The level of customer service I got from the Apple Store when I got my 4S replaced was faultless. Panic.plist are a hardware issue and as such a replacement is needed.

I was getting the random restarts, and panic.plist error as well. I brought my phone in and they said the hardware tested fine. We are now doing a restore from back up (typing this on a store computer while I wait). I will let you know if this corrects the issue.


I was told mine was due to instability in my SiriusXM, Facebook, and Skype Apps.

A restore from a backup doesn't seem like the best option. Why dont you try a fresh one? If there is an application issue whouldn't that restore the OS with the issue as well?

I had to wait about two weeks for my local provide to call back but it was worth waiting. The phone was replaced with a new one. Apparently it was a hardware issue. It would be great though if there is an official statement about these panic.plist log records.

I agree. Restoring from a backup or even restoring as new will not make any difference with panic.plist, this is a hardware issue and as such only having the iPhone replaced will sort it out. I think the lady who Jon Beckerman dealt with in the Apple Store was perhaps less than knowledgable and thought perhaps restoring it would/could fix the issue.


When I first contact Apple Care shortly after getting my 4S. Has soon as I mentioned panic.plist, he put me on hold and then came back after talking to someone about it, and said that this is a hardware issue and that he could make a genius bar appointment and asked me which store, he then mentioned that the 4S would need replaced and told me to take a backup before going to the store.


When I took my 4S into the Apple Store and mentioned what Apple Care had said, he sat with me at the tables in the store that have the macbooks on. He then ran something on this device that he had that looked like a iPhone 3GS, he switched on wifi on my handset and ran some diagnostic tests. He then said he would replace my handset.

If you have the time to visit the Apple store twice, don't back up your phone yet. Just make an appointment and show them the log. Once they say they're going to replace your phone, then back up at home and go get the new device. My panic.plist was earased after backup for some reason 😟. So the person in Apple store just asked me to restore to factory setting and redownload the apps batch by batch. Now I have to wait for the panic time bomb to go off...

The thing with the logs is, they can diseappear before the appointment. What I did was. I touched the panic.plist entry, the log then appeared on the screen. I then touched the screen and select all appeared, I then selected all and chose copy. I then pasted it into an email and sent it to myself. I read the email on my PC and printed it off. I'm pleased I did this because by the time my appointment came the log had cleared itself.
