My iPhone 5s suddenly restarts

My iPhone 5s suddenly restarts, this happens when the device is locked. reboot takes about 5 seconds.
Is a device unlocked

Back up and restore via iTunes. If the problem continues, restore as a new device and test. If the problem is solved, there is some kind of corruption in your backup file. If it continues, take it to an Apple Store for evaluation of a possible hardware problem.

Hi kyawlin,
Thanks for visiting Apple Support Communities.
I recommend trying all of these steps if your iPhone is restarting unexpectedly:
iPhone: Hardware troubleshooting
http://support.apple.com/kb/TS2802
Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIs and corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 30 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.

My Iphone 4 suddenly blackout and restart by itself. After that it reach the restore screen. Tried to do restore but it come out Error (9). Anyone can help?
I tried to restore in normal mode and DFU mode, both of it still give me error (9).
I tried using other cable and computer but it still the same.
Anyone out there having the same issue that can share?
Is this a hardware or software issue? My warranty already over and have to solve this problem by myself.
Please help.

Did you check your security software settings?
Error 9: This error occurs when the device unexpectedly drops off the USB bus and communication stops. This can occur if the device is manually disconnected during the restore process. This issue can be resolved by performing USB isolation troubleshooting, using a different USB dock-connector cable, trying another USB port, restoring on another computer, or by eliminating conflicts from third-party security software.

My iPhone 4 keeps restarting it's self & Won't Charge

"APPLE HARDWARE/SOFTWARE PRODUCT PROBLEMS WITH MINE & WORLDWIDE"
1.
24-06-2011
As from Friday 24th June 2011 when I purchased my iPhone 4 it Won't Charge, stays in the red & go above 5% even after 2-3+ days no difference charging plus I tried x4 different Apple charges but it made no difference at all to the problems with the iPhone 4.
2.
24-06-2011
iPhone 4 keeps restarting it's self every 30 seconds
3.
24-06-2011
I do a system restore many times via iTunes
4.
I do a hard reset by holding the power & home button for 45sec x5 times
5.
I do a battery calibration by holding the power & home button for 25secas I'm told via online forum
6.
Just finely get the iPhone 4 updated to latest 4.3.3 OS via iTunes
7.
I leave iPhone 4 to completely dis charge where it won't start at all & then recharge it where charge holds for a couple of hours but then only to turn itself off when the power meter is reading 64% but won't restart after pressing power button.
8.
So I pug the iPhone 4 back on its charger for a couple of hours but it still reads only 1% battery power so I do another by holding the power & home button for 25 seconds as I'm told via online forum up to which the battery meter reads 96% as to will not charge no higher than 93-96% but again the seconds later the iPhone 4 again starts keeping restarting it's self every 30 seconds nonstop all over again.
9.
Nothing has help with this piece of Apple ****.
10.
Reading more online forum where this is a very common problem with it seem that all iPhone models, iPad’s, iPod 4 it also had similar problems as did mine.
11.
Just finely get the iPhone 4 updated to latest x4.more times of the iPhone OS via iTunes which has made NO DIFFERENCE to the continued problems with this APPLE PIECE OF CRAP.

I plug it in to my computer where it Shows it’s charging a CHARGING icon in the power bar at the top right hand corner of the screen & then a PowerPoint icon in the power bar at the top right hand corner of the screen where then continues to restart its self every 30 seconds.
13.
01-09-2011
Now after a doing a battery calibration by holding the power & home button for 25secas I'm told via online forum. But this time each time it restarts 90% charge, 85% charge, 80% charge, 76% charge & that continues like that again, again & again, what a piece of CRAP…
14.
01-09-2011
Again I plug it in to my computer where it Shows it’s charging a CHARGING icon in the power bar at the top right hand corner of the screen & then a PowerPoint icon in the power bar at the top right hand corner of the screen where then continues to restart its self every 30 seconds
15.
01-09-2011
I Plug it in & once more I do a system restore via Apple iTunes to see once more if it will make any difference, like that will do anything ‘YEA RIGHT”.. And the answer is “NO WHAT A SURPRISE” Now showing 74% charge, continuing to restart every 30seconds
16.
01-09-2011
72% charge, continuing to restart every 30seconds & then showing a PowerPoint icon in the power bar at the top right hand corner of the screen where then continues to restart its self every 30 seconds.

01-09-2011

18.
Now showing 74% charge & still continuing to restart every 30seconds.
19.
Won’t charge at all while turned on
20.
01-05-2012
Still won’t charge when plugged in plus there is NO CHARGE SYMBOL on the screen to show its charging & so it doesn’t charge...
21.
19-05-2012
Now upgraded to iPhone 4 iOS 5.1.1 & it now continues to REBOOT/RESTART every three to five second regardless of whether it’s plugged in or unplugged NOW & the ONLY way I can get some sort of charge into it is to turn off the iPhone 4 completely but only after it already plugged in to the power & after it’s already restarted it’s self again buy holding the POWER BUTTON down plus flicking the Phone shutdown touch screen button across But still not fixing it’s problem regardless of how many times I’ve upgraded the iPhones 4 iOS MAKING THE iPhone or any iPhone so far totally the most useless mobile phone I’ve ever had/owned & I’ve had a lot of Mobiles over the years that when I get them I test every feature they have to the max in order to make sure there are no problems with it but this time I’ve discovered that Apple iPhones are a piece of TOTAL CRAP and contacting Apple is imposable to do & Vodafone is almost just as bad & certainly not buy email HA?

Hi, did you ever solve this problem?
My 1 year old -- ha! one month out of warranty -- iPhone 4 has been having a nearly identical problem over the past few days.
It started by dying completely so I had the battery replaced, thinking it was simply battery issue.
It then worked again for a moment but started doing exactly what you describe, going through a reset cycle (longer than 30 seconds but who's counting). And it felt quite warm.
Did hard reset, plugged into wall charger and MBP USB but the new battery wouldn't even get a full charge (a whopping 92% after nearly two days). It would even lose battery when plugged in if I opened an app. And all the while plugged in, if I left the phone on, it would cycle through these resets. So I turned it off to try to charge it.
Now suddenly, it's dead again. Totally black, and hard reset does nothing. Up until two days ago there was nothing wrong whatsoever with this phone! And I hadn't even installed a new app that could be the root of the issue. No idea whatsoever what caused this.
Any help would be much appreciated!!

My iPhone 5 suddenly could not hop onto LTE anymore, after updating to IOS 6.1

My iPhone 5 suddenly could not hop onto LTE anymore, after updating to IOS 6.1. I know there is LTE coverage at my house, since before I updated it, it could hop on to LTE just fine, in the same location. My Carrier is CSL Hong Kong. Does anyone have this problem? If so, does anyone have a answer to it?

Hi AEEA-Family,
I also did the update this morning and had the same problem also on Vodacom. The whole morning after the update I have No Signal, turning the phone on and of gives you signal for a couple of minutes then it drops again to no signal.
I've just made the following changes on my Phone and all seems ok again.
Here are the steps I took to resolve it on my phone.
1. Go to "Settings" > "Carrier" > Turn off "Automatic", wait for list of Carriers and select "Vodacom-SA"
2. Go to "Settings" > "General" > "Cellular" > Turn off "Enable LTE"
3. Go to "Settings" > "General" > "Cellular" > "Cellular Data Networks". Then Change EVERY APN from lte.vodacom.za to internet
After I made all those changes I did a hard restart of the phone and now all seems fine.
I suspect the update this morning Enabled all Vodacom's LTE settings, yet Vodacom is not 100% LTE yet in our areas and this is causing the problem.
Hope this helps other people.

Everytime I touch my iPhone 5s, it restarts/crashes

I was using safari on my iPhone, then suddenly the screen went black as if I'd turned it off, the apple sign popped up, and then it came right back on. Since then, I can unlock my phone, but as soon as I click on an app, the same thing happens. I keep trying to manually turn it off, but it restarts on its own before I get the chance. Has anyone else had this problem? What do I do?

The calendar on my iPhone 4s suddenly went blank and says NoEvents anywhere. What happened and how do I get the information back?

The calendar on my iPhone 42 suddenly went blank and says No Events. How do I get my data back?

I've been having the same problem every 3-4 months: the calendar app seems to hang up, I either reset the app/phone or wait it out, then presto! all internal calendar entries have been deleted. Unlike others in this thread and elsewhere, I am not using iCloud.
Interesting fact: while following the suggestion to hide all calendars, then show all calendars, I noticed that the internal calendar option is MISSING. It's like it just doesn't identify that there ever WAS an internal calendar. Really? Argh.
Apple Support: are you guys monitoring this? I've seen a few similar postings, so I don't think we're alone...
Granted, I have more than a few entries - years of calendar/appointment history have been imported from my old Palm Treo. Thanks to slow performance and odd calendar app crashes, I am very well aware that the iPhone's calendar isn't nearly up to the task of handling this many entries, and have been working to get the quantity of entries down. I must be up near some threshold, as response time seems to have improved with several deleted entries, though it was just before the crash+data loss.
Fortunately, I try to sync with my Outlook calendar nightly, so I do have a backup. However, this type of data loss and instability re VERY painful for those that actually USE and practically LIVE by their calendars. Here's hoping I can remember today's entry modifications...
One additional complaint: WHY can't I edit a recurring appointment WITHOUT it creating a NEW one? Crazy... For all the things this smartphone does well, it does several things VERY stupidly.

Iphone 4 sudden decrease in audio quality and right earphone not working

This is really strange --- my iPhone 4 suddenly stopped playing music in the right headphone - in all headphones and even in my car AUX jack. Also, the sound in the left headphone is remarkably muffled and low quality.
But if I pull the jack out a tiny bit, right before it comes out all the way, sound plays normally through both headphones for a split second.
I tried the cotton swab and rubbing alcohol, tried compressed air.. any ideas what could be the cause? I'm beginning to think it might be like a connector or something deep in the jack got loose maybe?
Thanks for the help!

Windows 8.1 Suddenly Restarting Again and Again

Some common problems are exception code 0x80000003. This means a hard

If this happens, make sure a debugger gets connected, and the
system is booted /DEBUG. This will let us see why this breakpoint is
happening.
