iPhone 4 Turns off randomly?

I have same problem and will go to apple store.

I have this problem now. I don't know if it's from the recent update or from me putting the passlock on. I did both at the same time. I baby my phones. I've never dropped it. I think once it does it once, it's a paper weight. It seems like whenever I do any thing graphics intensive it does it. ie: games, videos. The screen gets jittery then shuts off. It cycles to recovery mode then shuts off again then reboots as normal sometimes taking longer than usual. It doesn't matter if it's plugged in or not. I'm goin to cleveland tomorrow for an exchange.

Hi I have been reading all of your post and I am relieved to know I am not the only one with this problem! My phone started randomly shutting off by it's self about a month ago. I would get the Apple logo and it would just stay there. I took it in to the Verizon store and they treated me like the plague telling me they would not be able to touch the phone to troubleshoot it because it was an Apple product!!! I bought my phone through Verizon!?! They then proceeded to tell me I would have to take it to the Apple store; which happens to be in St.Louis..... I live 1.5 hours from there! So my frustration is..... Had I known that I would of never purchased the iPhone! And what am I supposed to do with my phone? I waited so long for this phone and was very pleased when I first purchased it in March- now I am beginning to regret buying it!!!! Seriously thinking of purchasing a Droid! And sticking this phone on EBay! Any suggestions???

I have been having this problem for quite some time now. It happened a few months a go and it just turned on and off on it's own for two days - so I thought it was done and that was just some freak incident. I was away on business last week in Alexandria, VA and it turned off as soon as I got there. It turned on a few times but it was mostly off - I dont live in that area and I use my phones GPS system - talk about a lost person. 😠 I've updated the software, deleted some apps and still no change. I live two hours away from the closest Apple store and even if I go there and they actually give me a new phone, according to some of your posts, that isn't a guaranteed solution. This is very frustrating!!! And I have always been a big supporter of Apple products, but what is going on, Apple????

Just changed service yesterday and my new iphone turned off twice during conversations and once locked up, it restarts itself within a few minutes. Today I went to the store and they said to do a restore and if it wasn't messing up while i was in the store they couldn't swap it. I got at the edge of town and it locked up while i was trying to answer a call, by the time i stepped in the door of the store it restarted itself. I updated the software and it's just turned off again during conversation. I live an hour and 1/2 away from an apple store. What to do? I feel like the service provider should deal with it since it's only a day old being used.

This is my third iphone but with a new provider, i've never had any problems with them.

I have an iphone 4. I had the battery changed. now it turns itself on and off automatically. Does anyone know why? and how can I fix it?

Anyone else not able to turn phone back on unless it is on the charger?

having the same problem currently. did you get any solution yet?

i had mine last all day after a restore, but it turned off by itself and wouldn't turn back on until i got to the charger. i DEFINITELY had plenty of battery left too.
