My iphone 3gs turns off then on, what's up?

It is cycling on and off. It has a full charge.

It sounds to me like you may have a loose connection inside the phone, battery connector or sleep/wake switch. I say this because you mention that tapping the phone on the back seems to cause it to shut down. I would recommend taking it to Apple or a trustworthy repair shop and have them look it over.

Why does my iphone 3gs turn off then on after I installed IOS 6?

Hey, right now my battery is dead on my iphone 3gs. When i plug it in it shows the apple( to show that its turning on) then it turns off. It repeats this constantly until I get frustrated and unplug it. I tried to plug it into itunes, to restore it, on my macbook pro but it doesnt show, and it just reapeats the turning off then on process.
Someone PLEASE HELP!

The Basic Troubleshooting Steps are:
Restart... Reset... Restore from Backup... Restore as New...
Restart / Reset

Try this First... You will Not Lose Any Data...
Turn the Phone Off... ( if it isn’t already )
Press and Hold the Sleep/Wake Button and the Home Button at the Same Time...
Wait for the Apple logo to Appear and then Disappear...
Usually takes about 15 - 20 Seconds... ( But can take Longer...)
Release the Buttons...
Turn the Phone On...
If that does not help... See Here:
Backing up, Updating and Restoring

If you try all these Steps and you still have issues... Then a Visit to an Apple Store or AASP (Authorized Apple Service Provider) is the Next Step... Be sure to make an appointment first...

IPhone 3gs turns off while having 60-80% battery

hello, iphone 3gs turns off while there is enough battery to be consumed. Round about 60 to 80 percent battery is more enough to keep alive an iphone for a whole day long. what suggestion you recommend, help asap......

You could try to disconnect and after a few minutes reconnect the battery. That theoretically resets the phone BIOS and is supposed to help regarding the reboot issue (see post by NIKKOH007) http://discussions.apple.com/thread.jspa?threadID=2471090&start=2055&tstart=30
Or replace the battery altogether with a newer, iOS 4 compatible battery. At iFixit.com they have come to the conclusion that not all batteries in the 3GS are necessarily iOS4.x compatible or a battery defect may be exposed after updating.

My iPhone 3GS turned off suddenly

My iPhone 3GS turned off suddenly and when i switched it on it give me that there is no battery then when i charge it i fined that the battery between 60% to 30% i have tried to restore it but the same problem came out
i bought my iPhone 3GS since Apr 2010

This sounds like the same problem i'm having. I have to upgrade my os to most current. Really don't want to do a restore. I've read another post from someone who's problem seemed the same as mine and it was actually the battery. After having battery replaced, it worked fine. Whatever the problem actually is, I hope it won't cost a lot to fix.

HT1430 my iphone 3gs turned off and on abruptly?

my iphone 3gs turned off and on abruptly?

Try holding down the Sleep/Wake button and Home button at the same time,
Continue to hold both down until you see the Apple Logo on the screen. Once you see the Apple Logo on the screen let go of both buttons and allow the iPhone to reset.
Hope this helps

My iPhone 5 turn off then turn on like restart.

Hello, I need some help please, some guy fix my lock button but after the fixed it, my iphone turns off then, it turns On like restart every 5 minuts or when I using it.
I call back this guy he told me that is the screen, but that's really stupid I dont think is the screen. I think is the battery, maybe this guy changed my battery.
Please can someone help me? what can I do??
I found on my diagnostic and usage data Panic.ips Incident identifier: BFBB2519 CRC ERR!
what that means??

I'm also experiencing this problem. Several old posts suggest cleaning the charging port, but I had no luck. This is happening on my iPhone 4S and my iPad. It could be an app issue since it's only happening for some people.

IPhone 3Gs Turn OFF suddenly and Critical

Hello everybody,
How may you assist me about my iPhone 3Gs.
My iPhone suddenly turn off while the battery is recharged full condition.
it's turn off suddenly without nothing and i tried to turn on (hold on the power button) but doesn't work. As long was turn off the body of iPhone became hot the temperature i afraid to be exploding like a boom because temperature almost 40 C.
i bought it new from legal provider mobile since february 2010. yes warranty but how's happen?
Thank you for helping and thread this message.

That just happened to me today. I found the solution in the discussions....
Press the sleep button (aka power button) and the home button for 5-15 seconds (it took mine 12 seconds). The Apple logo appeared...took about one or two full minutes to boot up, and then my home screen appeared as usual. No data loss at all.
The post where I read this said to ignore the slider that comes up after you press the sleep and home buttons. However, when I did it, no slider appeared.

My iphone 3gs turned off and wont turn on or connect to itunes. its fully charged, and told me to reactivate it, but it wont connect. what do i do?

what do i do?

I have the same problem. My iPhone 3GS was working just fine until I upgraded the OS to 5.0.1 a couple of days ago. When it complained about SIM card, I got that replaced and still the problem persisted. I tried to activate the Phone using my Wi-Fi and that also did not work. The phone has become unusable now.
When I contacted the CSR, he says that my phone already would have broken and that is why the upgrade did not go through which is not a fact after seeing these postings.
Apple, instead of finding a solution to this, recommend buying another equipment. Is there a way to revert back to older OS?

IPhone 3GS turns off by itself and then needs restored.

I've had this phone sitting around in my desk for a good two years at least because of this problem so I don't think there's a warranty anymore. It turns itself off within a minute of me turning it on and when it's on it says that it needs restored. I've restored it a hundred times now. It stays on while it's restoring but it turns off when it's done and I have to start the whole process over again. I've read through a lot of threads but nobody seems to have the same problem, or at least they don't mention it needing restored. Could this be the power button? It looks a little bit sunken in.

My iphone 3gs turns off frequency by itself after i updated to 4.3.1

My problem is after I updated my iphone 3gs to 4.3 version it turns off automatically within 2.3 minutes even with full battery and I have to press home and power key to turn it on. But weird thing is that if I use my iphone to play games or listen to music or charge then the iphone won’t turn it off. I tried reset, recover and it won’t work .I also tried to downgrade but I don’t have a backup. Can anyone help?

I don't know what you mean by "recover" and you can't downgrade the iOS. You need to do the basic troubleshooting steps described in the User Guide:
Reset phone
Restore phone in iTunes using a backup
Restore phone in iTunes as new, without using a backup
If restoring as new doesn't help, you had a hardware failure during the update.

Iphone 3gs turns off

hello my problem is that my iphone 3gs is just turning off even though its 76% or 56% percent charged i went to the phone store and restored it and then synced it to my mac as a new phone but its still turning off.i even deleted some music to see has anyone else had this problem?

I am having the same issue as well.
My 3GS would be charged to full (according to the battery indicator), but it would shuts off randomly whenever I use the application or browse the internet. I can't turn it back on and it would show a low-battery sign even though the battery life is still at more than 50% when it shuts off. Hard reboot dont even solve the problem, and the only way to turn it back on is to plug it into a charger.. even then, the phone would show that the battery is at whatever percentage when it was turned off (more than 50%). I bought the phone about 50 days ago and it was brand new out of the box, I never experienced this problem up until I upgraded to IOS4 and tried to download a game called Mancala, the download failed and the phone was frozen.. and then this problem started to show itself. I tried restoring the phone twice and even wiped off everything inside and start it off as a new phone, but the problem still persists.
Anyone know if the phone is hardware defective or is it the IOS4?
Thanks
Edit
Another note, when I plug it into the charger, the battery indicator would go from 50% to 100% in less than an hour. What could that be?

My iPhone 3gs turns off randomly (applecare sent it back as it was!)

Hi, had my iPhone 3Gs 32GB Black since about August 2009. From the outset it has turned off randomly ever few days or so, usually when I am in the middle of a call. I tried resetting the phone. Removing all the apps. etc. etc. but no luck.I stuck with it thinking that the problem would go away or that some future software update would fix the issue but also no luck.
So I took it into Movistar (the dealer for the phone here in Spain) a couple of weeks ago and they duly sent it off to Applecare for repair. Apparently you cannot do that yourself, it has to go through the store.
Anyway, got the phone back today with a really shoddy looking photocopy from AppleCare Service in Cork (Ireleand) saying that " their technicians could not find any problem with the phone..." blah blah blah. and that the problem should fixed by reset!
So what do I do now. I know that if they have not actually found the fault then the issue will persists. The Movistar sales woman said to just bring it back in that case and they would send it off to Apple again (for another two weeks...).
Is there any way I can contact Apple CAre direct about this? Anyone got any suggestions?
Cheers,
Tony

Thanks, but no Apple stores in Spain. Have to go through telco. Movistar. Will just send it back again for repair... see if they can fix it this time or give me a replacement.

IPhone 3GS turns off randomly.

I happen to have an almost 2 year old iPhone 3GS that I once bought brand new and it has this problem that when I fully charge it, it doesn't even drain down to 50% before it gets stuck, dims the display, slowly fades out with black stripes and all, turns off and never gets back on. Unless I put it on charge again, which takes about 2 hours to get turned back on again. I've also noted it turns off on special occasions like when I take photos or type someone a message.
And just to let you know, I've already restored it once. So, what do you all think could be the problem?

These features are most common due to faulty battery. Make Genius reservation and take iPhone to Apple Store for free quick battery diagnostic testing.

Iphone 3gs turns off since 5.1.1

Hello since this ios 5.1.1 update my 3gs has basicly killed itself it turns off randomly even if its 80% or 100% personally i think apple should give me a free repair seeming as they're software (itunes) made me update to 5.1.1 and since then it turns off if anyone knows how to fix this then it would be appreciated
thanks.

I have the same issue as well, now it has become nothing more than a paper weight to listen to music.
Bloody phone needs to be constantly plugged in .
phone calls will last 3-5 mins unless it is plugged in, same for using wifi, data, etc.
I shut down all the apps and still same problem, often enough at 98% power, the phone will shut down, especially if using Safari/wifi, or data.
My phone is all original, I never believed in jail breaking or modifying any of my electronic equipment, I have restored my phone at least 4 times, what a waste of time.
I am lucky enough that my company supplies me a BlackBerry (that I dislike) but at lease I now forward all my calls to my Co. phone, but not everyone has that luxury.
I went to an Apple store, I did not get to see a technician (wayyyy too busy), but I saw a service rep. when I explained the problem, they would hmmm and hawww, and constantly say Yeahh, and finish with Y'know that 3Gs is quite old, you should be upgrading to the 4gs! *** ???? is that your answer. I said since I up graded to 5.1.1 I have developped these problems shortly after the up grade. you can't even down grade back to the earlier version before the upgrade.
Marcus, I think Apple is too big to think of us simple clients, and just don't care. Right now I am really considering the new Samsung Galaxy SIII.
After seeing all the frustrated good folks that have this issue, and seeing how Apple is doing nothing about it really burns me
