Iphone 3gs shuts down & reboots on its own.

The 2 yr old iphone 3gs shuts down on its own and the silver apple icon pops up ~ the phone boots itself up. This has been happening more frequently, since Dec 2010. I could be on the internet, or using any app and it does this. A couple times I had to simutaneously hold down the power and home buttons to turn on the phone, and, or, unfreeze the phone. I always charge my phone, and regularly sync it with the latest upgrade(s). What is going on?

I had this, but I have now rectified the issue. It's an app?
I de-selected all my apps and just left the standard ones on.
I did a full restore from backup but did not sync any apps.
Problem solved, no more dropped calls. No more apple logo for no reason.
I am slowly re-adding my apps, 1 or 2 at a time, I have over 150 so it may take a while but so far I have reloaded about 10 of my most used ones and still everything fine. I will find the one that caused the problem eventually!!
Happy bunny again though, as I have a phone that can actually make a call for more than 5 minutes!!

Why does my iphone 3gs shut down when battery gets to 80%? have installed new battery and nothing changes?

Why does my iphone 3gs shut down when battery shows 80%. a couple of months ago is shut down at 60% but has continually gotten worse. this was before 5.0. i took it to a repair man and he tried a used battery, a new battery, and the original battery. nothing helped. 5.01 didnt help either. What is my problem?

Fully discharge the battery (till it shuts down and won't turn on) and then fully recharge it (100%). This will recalibrate the battery meter. You may need to do this a few times.

IPhone 3GS shutting down randomly...

Hi,
I was wondering if someone has experienced an issue where an iPhone 3GS shuts down randomly. The issue started tonight just a few minutes ago, the only thing I installed yesterday was iOS 5.0.1. Personally, I don't know what has happened, I do know that my brother has downloaded some songs using the Download Lite App from the App Store. Curiously the issue started occuring after the downloaded one song using that app, but other than that I can't find a problem indicator.

I also having the same issue with my iPhone 3GS with iOS 5.0.1, except most the day went by okay for me until near the end of the day. Perhaps I don't use my iPhone as frequently as you guys are but when I really on to something on it, it just shuts down like a Window virus. (hehe)
Also find some more details on my similar post:

Thanks for sharing comments/problems guys. It really means a lot.

My IPhone 3GS shuts down

My IPhone 3GS shuts of while making a call & when the wifi is on. I need to connect it to power to put it on. What's to be done? Thanks, E. Frank

try a reset, hold down the home/power button together for 10 to 15 secs or until you see the apple logo and then release. Then wait for you phone to boot back up.

My mac shuts down suddenly on its own

Please help
Since installing 10.4.8 my mac has been shutting itself off on its own.
While I would normally applaud such energy saving activity, it isn't
appreciated when I'm in the middle of doing something.
Pretty much that is the story: mac shutting down suddenly while I'm busily typing something. One moment working, next machine has turned itself off.
None of the logs show anything interestingly amiss, but I could be wrong.
Anyone else experiencing this sort of thing?
Thanks in advance,
Carol Hatcher

My Appologies. I mistakenly thought that since I filled out the
fields below the message box with the model, os and other details that
they would be visiable to all. What a fool i was.
I have a iMac G5 running Mac OSX 10.4.8 right now.
Other details:
Processor: power pc
Memory : 2G
I have owned it since May of 2005.
The shutdown now occurs while logging in. It took me three tries
tonight to get up and running.
Also, when logging in, i have to wait over a minute for the keyboard to be recognized - no response in the password
field.
Best wishes to all and thank you all in advance,
Carol Hatcher

My iPhone 3GS shuts down by itself.

What shoud I do? After intalling ios 5 my iPhone shuts down and reinitiate by itself several times a day! What's going on!?!?

Hi,
It probably wouldn't hurt to Check that All your Apps are compatible with iOS 4...
And If you haven't already… you could try the following Troubleshooting Steps:
1) Restart
2) Reboot
3) Reset
4) Restore (from Backup)
And if those 4 Steps don't Cure your ills…
5) Restore as New…
See this Link for Restoring:

Hope this helps,
Cheers

IPhone 3GS shuts down randomly when SIM card is in

without SIM card it works properly! I have updated to iOS 5.0.1, also got a new SIM card from our provider, without results. iPhone shuts down and reboots every 5 minutes when SIM is in. Does anyone has the same problem? What can I do besides sending it to the Service?
Would a resetting help?

Some Users have Reported that a Restore as New has helped Resolve issues...
Backup and Set Up as New Device
http://support.apple.com/kb/HT4137
Try this First..
Turn the Phone Off...
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...

IPhone 3GS Shuts Down When I Get To 20% Battery - Battery Doesn't Last

So like everyone now, I'm experiencing battery issues on the 3GS after upgrading to 4.3. My phone can barely get through a 5 hour day at school & it's dead before I even get to work at night. I'm constantly having to keep my phone plugged in to the external battery I bought. My 3GS also automatically shuts down as soon as my phone reaches 20% battery. This never happened before iOS 4.3. Used to be the phone shut off at 2% battery, not 20%. Anybody else experiencing this? I hope this gets fixed in an upcoming update soon.

I have exactly the same issue with iPhone 4 iOS 4.3.3 getting empty battery shutdowns at 20% then at more than 20 % seems to be poor calibration but I don't know how to reach 0% if it keeps shutting at 20% anyways charging to 100% then restoring appears to solve the problem but it's only a matter of time then the problem comes back ... Any ideas

Iphone 3GS shuts down abruptly

My iPhone 3GS was shutting down abruptly. It had iOS 3.1.3, i thought a software update might fix the issue. But even after upgrade to iOS 4.3.3, i am still facing the same issue. Hard reset does not help.
Any help is appreciated.

Try restoring your iPhone.

IPhone 3GS Shuts Down when receiving a call

My wife's iPhone 3GS has an odd problem - sometimes - but not always - when an incoming call comes in the phone shuts down. The phone doesn't ring (or vibrate) it immediately shuts down to the power off state - and it's only after a while that I realise the phone is off - later I find out someone tried to call.
Has anyone else seen this problem?
It's a 32GB 3GS on the latest firmware 3.1.2 (7D11) and 05.11.07.

I'm having exactly the same issue with my iphone, and same specs. It's a new work phone so discussed with IT manager. She advised returning it so it could be sent back for repair. Would be interested if you have heard of any other fixes as not keen to be without the phone, although that needs to weighed against the fact it randomly shuts down when a call comes in!

Why does my Iphone 3gs shut down?

I got a second hand iPhone 3Gs for something less than a year now, according to my serial number it was manufatured on October 2010.
It worked well until about 3 or 4 months ago when it started shutting down at 20% or so and wouldn´t turn on again, it would only show that connect to power symbol, like if it was uncharged, but now it´s gotten worse and it shuts down at 80%, and I can´t even run a game for more than two minutes because it shuts down, so I can´t go anywhere without my charger and that´s kind of annoying.
Anyways, when I connect to power it turns on with the percentage it had before shutting down and if I disconnect it, it won´t run for more than 5 minutes before shutting down again. So I wanna know if I have to replace the battery, or that can be fixed on technical support or something like that.
Thank you.

I see, can you help me telling me if this is expensive and if it can be done on apple stores? There are no attention spots in my city so I don't wanna travel for no reason... Thanks.

IPhone 3GS Shuts Down for No Reason...

Hopefully someone can offer some insight. Recently my iPhone 3GS will shut completely off when I am streaming Pandora. I can start streaming on a full 100% charge and 30 minutes later the phone complete shuts off. When I turn it back on, it still shows an 80% charge on the phone. Not sure why it's shutting down like this. It never used to do that, and I could understand if the battery were dead, but it's not.
When this happens I have to either restart the phone all over, or if I plug it in it will restart automatically. This does not occur when the phone is plugged in and charging, only if it is off charge.
The battery does not seem to drain particularly quickly or anything. It just can't stream for more than about 20-45 minutes at a time. I can browse the web for an hour or more on it and it does not do this.
Thoughts? Suggestions?

Have you found anything out with this problem? I too have had this happen to myself and I restored my phone to factory settings and it is still doing it. please if you found anythig out let me know.
Best Regards,

IPhone 3GS shutting down during phone talk

Hi.
My new iPhone 3gs is shutting down sometimes when I talk on it.
I suspected it was a battery problem (I saw once the battery meter drop to zero), so I installed the "powerlogging" profile.
Now, the log in the itunes folder seem to suggest that "SpringBoard" is shutting down due to kIOPMPSAtCriticalLevelKey battery notification.
I already tried restoring the phone, but to no avail.
I'm running 3.1.2 (and won't upgrade because I hear many people complaining about the upgrade)
Thanks!

People complain about every upgrade. And the fact is, even it it was in the thousands (which it is less than that here, more like hundreds) that is a fraction of a percent to number of active iPhones. This last update is actually an important one as most of it was security related updates that fix holes in Safari and other parts of phone that will allow a bad website to pretty much get access to your phone data. So update. Who knows, could be since the update came out, they actually said what it fixed (normally they keep it generic but this time they said trying to fix security holes that would allow remote code execution) could be that since it was public knowledge a lot of script kiddies got hold of the hard core hacks and started posting stuff everywhere hoping to catch somebody just like you that was too slow to update and thus could be causing your issues.

When battery is empty my iphone 3GS shuts down and won't turn on for a day!

Hi, I desperately need your help!
When the battery on my iphone runs out, the device, naturally, turns off. But even though I plug it into my charger - nothing happens; the screen is blank and stays like that for some hours, even a day long. I then, of course, try everything - plug it into different sockets, laptop, try taking out the sim card - anything - just to wake it up somehow, but it doesn't react. Then miraculosly, it starts charging as usual - never on its own, but only when I re-plug it! And then it's as if nothing happened!
Has anyone had this problem? Is there a reasonable explanation or should I reclaim my iphone?
Thanxxx!

Standard troubleshooting steps in the following order:
1. Reset: Press the sleep/wake button & home button at the same time, keep pressing until you see the apple logo, then release. Ignore the slide to power off.
If no change, continue:
2. Restore your phone from a backup, note: if the problem is related to corrupt data, while this will restore a fresh OS, it will also restore the problem.
If no change, continue:
3. Restore as a "new" phone in itunes & re-sync your content. All saved data will be lost.
If no change, make an appointment at an Apple store.
