Iphone 3GS keeps rebooting

Hate to say, but if your phone has been rebooted, restored or recovered. It sounds like a hardware issue. Send it to the refuribish line with the rest of them. Now i know you said you restored it. but there are a couple other ways of doing it that might help.

1. Reboot methods. The first thing to do is try to reboot the iPhone, which you can do by holding the top button and the home button for about ten seconds. In some cases, the iPhone is actually still on, but a bug stops the screen from displaying anything, so you can reverse the problem by doing the reboot. If you still see nothing on the screen, try to plug the iPhone in and again try the reboot methods to see if you can get the screen to display.

2. Restoring the iPhone. If the iPhone shows up in iTunes, but it still doesn't seem to turn on, it's definitely a display problem. When rebooting fails, you can restore the iPhone from iTunes, and this should fix whatever bugs caused the original issue. Realize that you'll have to reload your music if you restore to another software version. To restore, plug the iPhone in, go into iTunes and click the iPhone's icon on the side of the select screen. Click on the restore button and agree to the prompt asking if you really want to restore the iPhone's software.

3. Recovery mode. You can put the iPhone into recovery mode if it has a charged battery by holding down the home button before connecting it to iTunes, then continuing to hold the button until iTunes recognizes that the iPhone's in recovery mode. Recovery mode is a bare-bones way of booting the iPhone that allows you to perform a restore when you're dealing with a serious issue such as the iPhone failing to turn on or display anything on its screen.

try one of these if you havent already. if still nothing, its time to take it in or get a new phone.

Hi slpscientist,

I have had the same problem, after hours of looking through support communities and numerous attempts to restore my iphone which was scuppered by it simply resetting once again, I decided to make a phone call to my girlfriend to tell her that my phone was simply not working so I couldn't use it for texting calling etc. heres the weird thing, first time round it simply wouldn't work. The call would not start, so she rang back which I failed to answer. When I went to reply to that call however, it seemed to work. Funny thing is after we spoke on the phone the iphone now seemingly functions fine. It no longer resets and sends text and calls fine. A strange one but it saved me a trip to the Apple store, it might not work with you but I thought it was worth a bash?

Here's my personal update. My mom and I visited the Apple Store and went to the Genius Bar where I talked with the rep about the intermittent shutdown issue. The iPhone was replaced with a new one and the whole process took like half an hour.

I suggest that anyone who has an iPhone 3GS and is still under warranty to call AppleCare and report the problem as it seems to be more widespread than previously tought.

You can set up your Genius Bar Appointment here.

There is a way to get passed it, I had that problem but I kinda forgot what I did search YouTube. Try resetting (home and power button) when it shows connect to iTunes . Then once it starts with the apple just hold down home button. I think that worked for me. Oh and plug it in with your computer and iTunes . Let me know, good luck

Hi,

My mom's iPhone 3GS is having the same issue. Today, I called AppleCare and the rep told me that he has been getting calls from other customers that are talking about this very same issue. According to him Apple is taking a closer look to the issue and set up an Apple Store Appointment for tomorrow. I'll post what happens in my visit.

I have to say Apple has been screwing up in the last few months in terms of product quality, damaged GPU drivers (and hardware in some cases) in 2010 MacBook Pros, iOS 5 battery problems, and now this iPhone shutdown issues.

Hopefully it will get better in the future.

My brothers 3GS had the exact same issue. We tried what couldbeWil did and it worked! When I rang the 3GS from my phone it gave a ring tone at my end but his phone wasn't ringing. He then rang me and my phone rang but I didn't answer. Then I rang him again and he 3GS rang and he answered. This seemed to reset something because it stopped the reboot cycle and the 3GS works find now. Thanks for the tip! :-)

Sounds to me like you are having 2 separate issues. One is caused by the battery replacement. If the new battery is faulty, the iPhone will constantly reboot every few minutes and give erroneous meter readings. At first it will be intermittantly rebooting, but will eventually start rebooting every few seconds. Constant rebooting will drain the battery to the point where it won't boot up anymore either (people often think the iPhone is bricked when that happens). I suggest putting the old battery back in, or using a different new battery. Then you should try more trouble shooting on the problems you have after replacing it.

Dropped my phone today, it wouldn't turn back on at all. Tried the usual reboot techniques to no avail. Opened it up to see if a connector had come loose, the #3 one seemed to pop out too easily so I thought it could be this ( had trouble in the with this sucker - my fingers are too big). Still wouldn't turn on but apple logo would appear when plugged into wall ( not showing when plugged into PC).

Long story short:

After reading Franks post and the previous mention of batteries, I swapped in my old battery ( havent used it in 18 months) and everything works like normal. No restore or anything needed.

Thanks for this thread.

Rebooting Issue - possible fix

Today had a replacement OEM battery put in my 3GS. After getting back to the office I noticed it was in a 2-3 minute reboot loop. Didn''t matter if I put in the PIN or not. Didn't matter what application I ran. After searching a lot of forums I came across this...

It certainly worked for me. It appears it might be a 3G network problem. I actually took the SIM out after reading a previous forum fix, but strangely the problem remained for a while. It could therefore be perhaps due to the battery calibration as each time it rebooted the new, yet to be charged at all, battery took huge leaps downward in % after each reboot....until... it stabilised at 14%. Now streaming radio and have had no rebooting for over an hour and JOYOUSLY... the battery percentage doesn't drop like a brick, which it did with the old 2.5 year old battery.

So I would suggest mucking around with Airplane mode and SIM cards until you get the rebooting to stop. Joy when it does!!!

Have you compared apple part numbers on the old and new battery? Some say that you should replace the battery only with one that has the same part number or newer.
