My iPhone keeps rebooting/shutting down by itself?

Same situation with my iPhone 5. Installed a new battery 4 months ago and it has been fine until now. I read a post on the apple forums that suggested toggling the silent switch a few times. I have absolutely no idea why this sort of sorcery worked, but it totally fixed the problem.

i had the sam problem bro...i changed my battery and everything was fine.get your iphone battery replaced...

Hello to everybody and sorry for my poor english, y had the same problem whit my iphone 4, it kkeeps rebooting every 2 minutes, but i fixed, y read a lot here and in other sites and try every thing, change the battery, restoration in dfu mode etc.

The solution of the problem was the battery connector, it has 6 solder points , 4 in te rear and 2 in front,the 2 solder of the front was unatached, so to fixit i had to re solder all the conector to the board, and thats it, problem solve, and my phone never reboot or crash again

I have had a similar issue with my iphone 5. I had previously replaced my rear housing. I must have damaged the battery upon removal, it was very well stuck. The symptoms were randomly shutting down perhaps due to the battery playing up. It would read a certain percentage for half an hour and than drop by 25% and than die.

I decided that the battery must have been damaged, I replaced it with a new one from ebay and everything worked well. I even had 30% battery at the end of the day. Goes to show the capacity drops a lot over a year.

Here is where I get to a similar issue as is brought up in this post. I put my phone in my pocket facing down and when I pull it out.. It's dead. Turn it on and everything's fine. Hang it upside down its flat..

I shook my phone a little and noticed that something, most likely the battery was moving around in there! I would guess that in the down facing position it touches against something it shouldn't or tha perhaps the movement causes that battery to stop feeding power to the mainboard. My solution has been to use double sides tape to hold the battery still.

I hope this is helpful, if that doesn't work try a new battery. Seems they cause a lot of issues in the i5.

Good luck

The exact same thing has been happening to my iPhone 5. I will be on any app or just unlocking my phone and it will just turn off and on sometimes 10 times in a row and lines will appear in black and white or red and green. I took my case of and the phone seemed hotter then it should have been and so I took my plastic case of and left it for 5 minutes and it seemed to have cooled down and it has not shut down for a week after taking the case off and not putting it back on. I don't know if it was overheating or if it has something to do with the battery.

I took my phone to the apple store when my phone kept turning off and lines were appearing and they replaced it, if it is in the warranty they will check to see if there is no preventable damage caused by the owner of the phone like water damage if there is no indication of this they replace it straight away in the store.

Well, that’s not the point anyway. We’re trying to fix an issue here so here are the ways, in which you can try to fix your iPhone that keeps shutting off, restarting or freezing.

Turn ON/OFF Cellular: As strange and absolutely impossible as it sounds, I’ve seen people get this issue sorted out by turning off their cellular data and then turning it on again. Arguably, this doesn’t work everywhere. But since this is the most simplest thing you can try, you should begin here. Don’t believe me? To do so go to settings → Cellular/Mobile → Turn On/Off Mobile Data.

Reboot iPhone: To reboot your iPhone, hold the power button and home button simultaneously for a few seconds. The Apple logo will appear on the screen and your iPhone is rebooted.

Reset iPhone: To reset your iPhone, go to Settings → General → Reset → Reset All Settings.

Faulty App: No matter how strong and protected the App Store is said to be, there are apps that aren’t really good for the health of your iPhone. One of these, possibly, could be ruining your iPhone experience. Did you download any new app that triggered the issue? It doesn’t matter if it’s a popular app or an app that no one has ever heard of. Just try deleting it.

Delete the app → Reboot your iPhone → Sync with iTunes and see if this sorts the issue.

Restore From An Old Backup: No luck yet? Try this method (it’s tougher if you’ve got an iPhone that keeps restarting too often). Connect your iPhone to iTunes on the system and then restore from an old backup. In case you got lucky, things will be back to normal.

Recovery Mode + Restore: This could be the best possible solution you could ask for. Again, it’s tougher to implement if your iPhone keeps shutting off or rebooting every two-three minutes.

Same thing had happened to me. There is a hard reboot button inside which is where the battery is connected to chip.

Open the battery and loosen the pressure. Don't pressure the iPhone in middle while fitting the case.

Simply change the battery and your problem will be no more

Hello, my IPhone 6 was under my pillow a single slept on it. Woke up this morning, now when I'm using the phone it goes on and comes back on immediately. I have tried doing a hard reset but still nothing. Please help, what do I do?

Same thing happened to me with a Iphone 5s . I replaced the battery , it was fine for a couple of weeks .

After that screen would not stay on , before rebooting. It wouldn't hold a charge. I replaced it again.

Now it's better than ever. Some batteries are more inferior than others .

My phone shut down nd will keep rebooting nd won't turn on it'll keep gliching on nd off plz help

i too would experience the same fault with my iphone 5 where it constantly rebooted on end and it came to a point where it wouldn't work off charge , i researched all possible solutions regarding hard rebooting , deleting apps , updating , and resetting to factory settings but it all didn't work , the problem was a simple hardware fault from dropping my phone , all that needed to be done was unscrew and open up my iphone and just remove the battery and reconnect it , the only problem was the connection and now it's working perfectly , instead of wasting money at phone shops , simply open your phone at home and make sure your battery is connected properly.

I have same problem now. Automatically shutdowns and rebooting many times then died. If I charge and use, it’s fine. Before this happen, my iPhone was overheating and drains itself. Since automatically shutdown, no overheat. But charge and use, overheating again. (I shocked my iPhone then it heats up and drain. So my battery was replaced.) Should I shock it again?

just replace my battery! I have solved it! Thank you!

I have an iphone 6s i updated it and after that the screen keeps blinking help me
