my iphone 4s randomly turns itself off please help

I have somewhat the same issue. At@t 16gb 4s randomly powers off. Alothogh I don't really know if it completely turns off or somehow logs out. And what's weird about it that sometimes I can turn it back on by simply clicking the home button or the power button and most of the time in order to turn it back on I have to press (the home button + volume button + power button) all at the same time.

Well my replacement is an exact back up of the old 4s used in the same way and gets no where near as hot. And the better news is that it no longer turns itself off.

Terry for info mine didn't turn off in camera mode but that seemed to be the function I remember using last before it switched itself off. I read somewhere Apple have had some problems that engineers are trouble shooting to do with battery consumption so it might be worth calling up apple if you can get a replacement from your service provider.

I have similar issue with my iPhone 4s as well. It turns off randomly, happened 5 times till now. I could remember that when ever its happening the battery is less than 50%, mostly in 30% range. One difference from the other peoples experience is that the phone does not power on what ever i do. I could also see little bit of heat in the back of the iPhone, so though the display is off I think iPhone is still running. I was able to switch it on after couple of hours and its intesting to see that time the % battery is almost zero. All the times iPhone powers on only when the battery is completely drained. Today i went to the Genius Bar, I explained to them the situation. They ran some diagnostics and said that battery is good. I thought that they will provide me with new phone. The person said that as they could not reproduce the issue he cannot provide me a new one. He has performed a DFU restore(Atleast I could remember thats what he said and took 6 to 7 min to do it) and said that I may not see the issue any more. He suggested that if it it happens again go to the nearest Apple Store. He really sounded dumb as he was asking me to go to apple store when ever it happens and what ever time it is, which apple store should i go if this happend at 10:00PM night(It happened once..), what should I do if I see the phone not woking when I are in office(which also happened once), should I drop every thing which I am doing and rush to apple store, fun. After I repeatdly asking these questions, he asked me to call the Apple Care(I have Apple care Plus on my phone) when ever ths issue happens next time. Hopefulley the issues is resolved with the restore. Is been 10 hrs now the and looks to be woking fine.

It happened again when i was writing this post now at Sunday 9:45 PM EST, tryed to reach apple care, do you know whats more fun, they are closed for the day and have to call during the business hours. I am planning to call Apple Care tomorrow morning. Not sure what the Apple Care rep is going to say, hoping that he will not repeat the same thing... Call us when the issue happnes, so that we can remotely diagnoise...

Will update the post with my experience.

As mentioned in my earlier post, my iPhone turned off it self yeterday night 9:45 PM. It woke up when all the battery is drained, 10:30 Am today. almost 13 hrs.

Spoke with Apple Care rep today, he is sending me a replacement.

Had the same issue with a 16gb 4s. I was advised to do a clean restore, not restore from my 3gs back up as I had done when I got the phone. The phone certainly seemed more responsive and didnt run as hot, power usage was also better. I didnt have the phone long enough to say the lock ups were cured as I exchanged it the next day. Posts elswhere indicate this has cured some phones but not all.

I have now had a replacement phone - I will wait and see.

I called apple care with the same problem. The only difference was I posted them the errors and after he read it he transferred me the some senior staff guy. I talked to him for a while and he told me they will send me a new phone for free but when they get my old 4s they are gonna send it to their head engineers because they want them to look at it. They took it very seriously and customer support was great.

Sent from my iPad 2

Any news? My 2-days old 4S is randomly shutting down too.

So here is my take on it...

I am sure (as apple admitted) that there is an issue with iOS 5 but...after going to the apple store few times and they restored it (not from backup) the issue remained.

2 days ago they finally replaced it and now the phone works like a charm last night around 8pm i disconnected the phone from the charger with about 85% battery and now...23 hours later i have 51% battery, so i can say for sure that it is not only ios 5 but also something with the first shipment of iPhone 4s's.

Just have apple replace your phone, worked for me.

P.S

BE CAREFUL,

when they replaced the my iPhone 4s 32g they handed me a 16g replacement and i didn't know till i went home to sync it. when i went back to the store they checked the serial of the phone and it didn't match with the serial of the replacement's box, so they said that i switched the phone and it wasn't the phone they gave me (basically called me a lier) it took me 2 hours to convince them of the truth and after they checked that my phone's serial was never activated till that day they replaced it and gave the proper replacement.

check your replacement before you are leaving the store!

same here mate got mine on the 18th Oct in the last week the phone has offed it self every day only by pressing the home and on button does it come back on?

Update on my 4s 16g white.... October 25th when it quit working and wouldn't come back on for hours I ended up taking it to the apple store, they ran a diag said nothing was wrong with the phone and to do the reset and don't restore the phone from a backup, use the icloud backup. So I did. A few hours later it's still hot, shutting off and turning back on randomly, lousy battery life and so on, so I call Apple again and they tell me to do another reset. It continued to do all the issues above.

Fast forward a few days to November 5th and the phone died again and wouldn't turn back on for hours. As soon as I got it up and running I called the apple store and made an appointment for yesterday. I took the phone in, they ran a diagnostic and told me that the issue I've been having is one that Apple is aware of and they're supposed to be releasing an update or a fix within the next couple of weeks, but just this once he'd go ahead and switch out my phone.... within 2 hours of leaving the store my "new" 4s is doing the spontaneous restarts and stays hot and apple has no clue. Talk about frustrating. I've never had an issue with any of my previous iphones save a busted screen here and there, but the new one is turning out to be nothing but trouble.

Bro just get apple care or use your 90 day warranty and go into settings - general - usage and go to diagnostics and copy and paste the errors and past it on here and call them and tell them to look at it and they will put a 700 dollar hold on your credit card untill you mail your old phone in. (to make sure you don't rip them off) and they will send you a new one I did that and this new phone is 120% perfect

I had my iPhone 4S replaced three days ago because there was a black speck in front of the front camera and under the glass. Updated iOS to 5.0.1 this morning and now the phone won't turn on no matter what combination of buttons I press. Nothing happens when I plug it into the computer too. HELP please.

I just got a 64gb 4s and I've been having this issue. I'm try a restore and then set up as new and going to see how that goes. keep you posted.😕

After about twenty minutes of panic and pressing any button, the phone came back on by itself!
