iPhone 4s Randomly Rebooting Post 8.3 Update

Update: I'm back to having the issue. The "Reset All Settings" seemed to resolve it for about 5 days, but it started happening again last night when charging the 4S. The other workaround (Settings>General>Auto-Lock, set to "Never", while charging) is still fine.

I too had this problem after having updated to 8.3 on my iPhone 5. I don't know if the fact that minutes after updating, i got a message from ATT asking me to update my carrier settings, which I also did, played a role. My phone would go into a cycle of multiple reboots if it was charging while in sleep mode, but would not happen if kept awake during the charging period. The phone would also get very warm during this time. My problem was solved by resetting the Network settings only, so there does seem to be some interplay with the carrier/Network settings and the new IOS that was causing the problem. Good luck everybody!

This method does work for my Iphone 4S now. Once I reset the Network Settings, i was able to charge properly (with the screen off). Hope this is a permanent solution. Thank you so much for discovering this gem!

Sorry guys, the "Reset Network" strategy doesn't work again. I realized that once I use a powerbank and then revert to a wall-plug charger, the problem will return. Perhaps one should avoid using powerbanks. If the problem happens again, just reset the network settings and it should work again (for a few days). Anyway this is really troublesome for me, hope any of you who found a better solution can shed some light. Hoping the next update would resolve this issue for Iphone 4S users.

I've tried both the global reset and network reset and neither work. The problem is intermittent (for me at least), and only seems to happen on average a couple times per week but on a very inconsistent schedule, so figuring out whether a change actually fixes things is very difficult. You pretty much have to wait a few weeks before you can be sure... one week it will happen 3 or 4 nights in a row, and then it won't happen again for a week and a half.

Very annoying, Apple! 😟

Not sure if it's just me being superstitious but this has worked for the past four nights...

Close all the apps

While in the home screen and not locked, plug the charger into my iPhone.

I found that if it's locked or in sleep (screen is off), my iPhone will reboot when changed.

Now that I posted this, I probably jinxed myself.

Yesterday i restore my phone 4S and with only mail and facebook installed, it's run like a new one. No reboot since.

Phone provider ( Telus ) ask for an update but i do not accept for a couple of days. Good news, it's not a hardware trouble.

I'm on a 4S with this issue. The device was nor reset nor restored, but in my case it helped to just disable the setting 'Control Center: Access on Lock Screen'. No more restarts while charging since then, even when Auto-Lock is enabled.

I Have found the solution. assuming that we all have a home computer which has the iTunes for sync, if we ever connect the 4S any other computer without iTunes (maybe having software like if ifunbox ) or for charging or any usb otg capable device or powerbanks or anything that tries to mount the 4S, this problem will surface. some lock mechanism failure causes this. To solve, connect to home computer, login to iTunes, access iTunes Store maybe check purchase history etc. and let the phone charge. Keep computer on till charging complete. Next charge can be done using normal charger.

Same problem, 4S restarts continuously when charging. The workaround is to turn off auto-lock, plug in the charger, then manually lock the phone.

Complete restored and working fine for one week. Finally i accept the carrier update and nothing wrong for three more days. Yesterday reboot problem came back.

During this period, dont install any other program and dont sychronised with itunes. Just charged with the same wall outlet.

What's faulty ? Phone, carrier update or the mix ?

Apple help me ! New Samsung's look very good...

I guess It shouldn't be the carrier update because we all have different carriers from different countries....

I agree but many carriers may use the same software.

I dont know, just try to understand what's wrong ...

I have same problem, only restarts when locking the screen while recharging (from multple chargers).

dbninva's fix of disabling the lock screen to charge fixed it for me.

I had the same problem even after a fI'll factory restore. What fixed it for me was to calibrate the battery, I.e. Letting it run down to 0% and switch off, leave it for a few hours to drain further, then allow it to charge for at least 6hours without taking it off charge (will work quicker if the phone is off when charging). once at 100% do a hard reset (hold home and power buttons together until phone reboots - no data will be lost). Then repeat one more time. Ive had no reboots since....touch wood.
