  1. Turning off Cell Data worked. While it was off I went into Numbers changed a couple things then turned on cellular data but left LTE off then made more changes and then turn LTE on. I figure that mixes it up with another solution I saw on a different forum.

    • hi can you hepl me please…it seems like you solve your problem with your phone by switching on/off cellular data…but you you be more specific please. What changes did you do after you left the cellular data off?

      • I think he just turned off cellular, then went and made some changes to
        the Numbers app. It doesn’t really matter. You can just turn off
        cellular, and then turn it on but turn off 3G/LTE.. after sometime, turn
        it on.

  2. do-it-yourself iPhone repair is quick, inexpensive, and isn’t as difficult as you may think! Whether you need iPhone 4S screen repair, dropped your iPhone in a pool, or, shattered the screen into tiny little pieces, there is an iPhone repair kit for you!

  3. This is interesting. When intermittent iPhone faults like this come up, people also come up with the most bizarre fixes. Turning cellular on and off has no relation to this and can have no effect at all on what is undoubtedly a hardware problem. But you do the “fix”, look at the phone, and – hey! It’s not doing it ! But you forget it was an intermittent problem, and whilst you’re staring at your phone after the fix and it’s not doing it, you convince yourself that this has fixed it. I’ve seen this sort of thing time and time again. You could convince people that taking a photo would “cure” it. Best guess of the reality here is that it’s a very slightly loose battery, and a small thump causes the mini-reboot.

  4. Please help me, my iphone 3gs won’t turn all the way on. It starts to boot up, shows the apple logo, then the logo dissapears, but it still on but just with a black screen, then it turns off with no screen. it keeps repeating this forever untill the battery dies, then i charge it enough and it does the same thing. all over again.

    • Try restoring your iPhone 3gs through iTunes. Connect the device to
      computer, fire up itunes and see if you can restore. If not, take it to
      the nearest Apple store.

      • Hi I have same issue. I have tried restoring to latest 6.1.6. The whole process worked completely but still iphone is restarting only. Please help because even apple genius has said that don’t know how to fix. Honestly I just need my contacts back. I have made backup but now I read on internet that backup doesn’t include contacts. Please help

  5. Someone fixed my power button but after that my iPhone 5 restart every 2 minutes before restart the screen turns like gray and turns off then on. So I shake my iPhone and I heard like a cable is disconnected, do you think that’s the reason? And what cable do you think it could be? Thank you

  6. Help !! Iphone5s cannot turn on . I already hold power off/on and home button about 10second . But still not worker . Actually my battery had a problem . Two day ago i bought new battery . Today iphone turn of automatic . How to do? Pleasee help :’) thanks

      • I already sold it yesterday . Because they said my iphone had a problem with motherboard and if i repair need to spend lot of money .. so sad .. i miss my iphone !!! however thanks you so much dear.

  7. I know this discussion is getting old, but just want to say that turning cellular data off then back on fixed it for me. Settings > Cellular > Cellular Data — switch to off, then switch back to on. That’s it. I can’t believe it, but it worked. I was minutes from leaving work to go to the Apple store. I don’t know how this makes any sense at all, but thank you.

  8. When my iPhone 4s randomly started rebooting every 2 seconds, simply holding down the lock button and home button set it straight, and then i plugged it back into the charger. I have no idea what caused it, but i thought maybe it was a connection issue?

  9. My iphone just won’t get past the actual reboot, as soon as it reboots, it turns itself off and starts again so I can’t do anything

  10. My iPhone 4 is jailbroken, has no memory left, and wont stop restarting?! I’ve tried the master reset with the lock button and the back button. It’s not letting me sync with ITunes, because there’s not enough space. like I’m just out of opinions

  11. Have the same problem, None of the solutions worked for me. Went onto the Apple site and clicked the link for support direct to my phone. Click on the message sent to your phones e-mail and it sends a diagnostic to Apple. within seconds I received a message telling me the battery is the issue. New battery required, hope this helps.

  12. My phone restarted it’s self well over 30 times in one day I was going crazy and couldn’t find any solutions. Apple Store couldn’t fit me in for a few days & none of the above things worked for me so I just rest the phone to factory settings and restored my back up & so far so good..

  13. I had no issues until I updated iOS 8. Now my phone stays on the start up screen with the apple. I’ve done everything possible. Grrrr tempted to buy a galaxy.

  14. hello , I have an iphone 4s , and always worked perfectly … until I upgrade to the 8 ips … since then , the iphone is always restarting … I do not know what to do ! I called the assistance they told me to do the restore as new, and did nothing , all the same !
    I know that the my phone was so well, before updating to ios8 , I need to downgrade to ios7 quickly !!!!!

  15. i have an iphone 5 and had no problems with resetting itself until i upgraded to ios 8. Then all of the sudden it resets itself at least 5 times a day. Then i had to do a full restore and work fine. Then 8.1 comes and i download that, it does it again. WTF APPLE!!!. I thought your os is supposed to be stable and now with ios 8 that is not the case. I am seriously considering switching to android.

  16. My 5s fell into water and when I put it to charge, the apple sign flashes on for a few seconds and then turns off. It repeats this and apparently gets no charge. When I hold down the home button and lock button, it says I should plug it in and connect to iTunes. But I CAN’T CONNECT IT TO ITUNES CAUSE IT KEEPS SHUTTING OFF. Help!!

  17. My iPhone 5s is only about 7 months old. Now all the sudden its restarting. I tried everything and nothing worked. I Need help. It blue screens for two seconds then restarts.

  18. Someone fixed my power button but after that my iPhone 5 restart itself ,before restart the screen turns like gray and turns off then on. and show apple icon .

  19. ‘Turning OFF and then ON cellular data and 4G’ worked for me. Thank you for the tip. Mine is iPhone 4S with iOS 8.3. 4S kept rebooting while charging on the power adapter, and never came to full 100% charge on the PC/USB charge. Hard to believe that a simple cellular data OFF & ON would work, but it does.

    • Same configuration. The hack to turn off and on the mobile data seems to work with my iPhone 4S as well. For the first night the phone didn’t boot any more by itself. I also turned off the possibility to use mobile data for some selected apps.
      Let’s see if things stay the same…

    • Hi, did your iPhone 4s keep restarting while charging?( every minutes ) Mine 4s after I downloaded a game name: Tower Of Sav… it keep restart every minutes…help me pls

  20. My iPhone 5s fell, it went off, i guess the battery got disconnected, took it in for repair, now it keeps on restarting, displaying apple log and then goes to restore mode, but when i connect it to itunes to restore and update, it will load the software halfway and then restart again. what must I do?

  21. This thing seems to be constantly trying to access the cellular network(in a dead zone) and buffer overflows and reboots. Rinse repeat. There is a bug in the wireless settings or driver being used for this POS phone. And F You Apple. I’m glad Steve’s dead.

  22. i have and iphone 5 with ios 8.4 and every time i unlock the screen, it shows diffferent colours and decides to reboot, this have been happening for a while now

  23. I have this problem before. My iPhone 5 restart randomly. Its battery bar does not change even I charge it or use it. The bar will show either 55%, 2% or etc and it’s not changing until the phone is restart. But, finally I got it fixed. I search on many website how to fix the problem. Some said that I need to change my battery, restore and do hard reset. I tried everything but it does not help at all. Actually, the battery and software are in good condition. The problem is the IC, capacitor or transistor inside. These are the steps that I do to fix my phone :

    1. I used the phone over and over, even it restart by itself everytime. I used it until there is no battery left. At that time you will not be able to start the phone at all because the battery is 0%, even if it not shown correctly on the screen. (It will stuck at apple logo and off)
    2. Charge the phone about 1 hour. But DO NOT switch on the phone yet. Wait until one hour. Then switch on the phone.
    3. Now your phone will turn to normal, but the battery life will become weaker than before. At least, it is not broken.
    *note: make sure you use the original charger and cable that you get from apple store.

    Now my phone are doing fine. Hope this method can help you fix your phone. Goodluck.

    • the thing is when you plug the charger it will automatically restart since 1% of its battery is recharged. How did u keep it off for 1 hour then?

  24. What the F is this Apple. My Iphone 5 keeps on restarting. i have changed my battery but still having the same problem. i do not know what to do now, i am really pissed off by Apple Co. i might switch to Samsung.

    • As they said buddy Apple is not Android… Android is 100 times more better than ios. Why ? Because The way i see it… iphone is for slaves. And Android is for people that can use their heads. aPPLE IS NOT FLEXIBLE AND WILL HOLD YOU TO THEIR LIMITS aND MOST OF YOU WILL DIE NOT KNOWING YOU EVER BEEN LIMITED bY APPLE. sAMSUNG IS ON THE OTHER SIDE ABLE TO DO WHAT APPLE DOES AND MUCH MORE. BUY ITS ONLY FOR THOES THAT HAS A BRAIN IN THEIR SKULL AND KNOWS HOW TO USE IT.

      • Uh.. the way I see it, is they’re both phones used to call, text and maybe play games on, or browse the web… same function.. different platform

  25. I have an iphone 5. Its 2nd hand from my mum and ive only used for 1 dAY… I get to school and I put data on and it reboots itself. hours past and now it turns on then I don’t even have 1 second to do anything to fix it and then reboots again and again and again.. literally as soon as it turns on it turns off again… HELP ASAP!!!!!!

  26. I would like to share my similar but weird situation. My iPhone 6 Plus has the same problem and every once a while it shuts down and restarts by itself since day 1 I bought the brand new phone. At first it didn’t bother me too much until one day I was on an important conference call and the phone did it again! What is really interesting is that the conference call kept going after the phone restarted, my colleague on the line said they were talking to me but I had no response for a minute, then they heard I was shouting for a charger so they knew I was still there. How strange is that??? I saw with my eyes that the phone restarted with the apple logo showing up but maybe it was just the screen shutting off or something? Anyone has any clue? Also my 1 year warranty is about to end on 10/26, I just contacted Apple today for the first time for this issue, Apple told me to reset my phone. I asked her what happens if the problem remains and I’m running out of my time to test it out, she said we will look at other options to fix it but after the warranty expires I may have to pay for the service :-(

  27. hi , i have reset problem with my iphone5s , because when it was resetting i suddenly turned off the iphone .so i wanna reset again but its not processing ,how i can fix it pls

  28. hello , I have an Iphone 5c . everything was working perfectly fine until today it when to the lock screen and then when I try to unlock it , it just restarts it self … I tried the lock and home button but nothing happen . What can I do ??????
