iPhone keeps randomly turning off

This is probably the best answer. I took the sim out before seeing this post, but had to take the phone (13 mini) to the Apple Store since I was at a point where it wouldn’t charge, and it wouldn’t even get to the unlock screen before shutting down again. I noticed that the SIM card was actually the problem and removing it earlier when I still had the ability to reset while it was attempting to charge would have most likely fixed the phone and prevented it from getting damaged more to the point where it doesn’t finish booting at all. When I took it to Apple they said it was a rear harness issue since the phone wouldn’t charge at all it wasn’t a battery issue. They obviously recommended I replace the entire part $299 or buy a replacement 13 mini for $400. Apple has seriously gone down hill and they’ve become more like an auto dealership that doesn’t fix the problem or repair decides, but just recommends the most expensive and profitable option (replace the majority of the components, or buy a new phone). I’m sure Apple is aware that the SIM cards are causing the logic board/rear assembly to become unusable, but knowing Apple it’s either a known planned obsolescence method, or they are award of it and prefer to let the phones die from their software update/sim malfunction to make people buy new phones and hardware for repair.

I can confirm that the SIM card was the main issue, since after I removed the sim and tried to use a back up work phone (iPhone 8) until I got a replacement, the phone did the exact same thing as the 13 mini started to break which was go from around 30% battery down to 1% and say it was charging initially but unable to go above 1%, then eventually not say charging at all and continue rebooting. Once I took out the SIM card after noticing that the exact same thing was happening to my iPhone 8, the battery went right back to its previous charge of 30% without it having charged back up. It was then able to charge normally and stopped power cycling. Something with the iOS update causes the sim to overload the logic boards ability to charge the battery, and that inability to charge will cause the phone to be unable to have enough battery to finish booting. Apple knows this is the issue since another used mentioned that an Apple Genius had recommended removing the sim and resetting to fix the problem, but they keep these solutions from the rest of the company/sales people/technicians or tell their employees not to mention it to their customers so the phone will become unusable/unrepairable with this method and they can try to profit from replacing huge components or forcing users to buy a new phone which is all they care about.

I have been having the same problem and my phone has been absolutely useless. Been in chat with Apple since 15:45 EST to no avail. Finally I was able to update to ios17.5 and so far so good. This is my absolute last Apple product. I'm done.

The same thing is happening to my phone aswell, I updated my phone to iOS 17.4.1 and after this update, my phone will just switch off every 10 minutes or so while I’m using it. Reading the comments I genuinely think this is the new update that has this bug that is causing our phones to switch off. I hope apple fixes this issue soon because it actually disrupts certain things in peoples lives.

Uh, there is:

Update iPhone manually

At any time, you can check for and install software updates.

Go to Settings  > General > Software Update.

The screen shows the currently installed version of iOS and whether an update is available.

To turn off automatic updates, go to Settings > General > Software Update > Automatic Updates.

Update iOS on iPhone - Apple Support (CA)

Also...

Update iPhone automatically

If you didn’t turn on automatic updates when you first set up your iPhone, do the following:

1. Go to Settings  > General > Software Update > Automatic Updates.

2. Turn on iOS Updates below Automatically Install and Automatically Download.

When an update is available, iPhone downloads and installs the update overnight while charging and connected to Wi-Fi. You’re notified before an update is installed.

You can have it automatically download but not install it. It's true for iOS 15.8.3 at any rate. The two switches for "Download iOS Updates" and "Install iOS Updates" only appear after you turn on "Automatic Updates"

Either of those methods would give you an opportunity to back it up before an update is installed.

What I don't know is if restoring an iPhone from, say, a Mac backup will also revert it to the original (backed-up) version of iOS.

TLDR ... Apparently it does not downgrade to the earlier version that was backed up. It only saves settings, files, and apps.

It's not like Time Machine for macOS.

Hi everyone, this is my first time on here not very tech savvy. I noticed after giving iOS permission to check out Google their 17 point something update, or another a few minutes later “”””” my phone started shutting down. Luckily, I happen to notice and got it back up.. there has to be something in settings where you can be notified or alerted before they do an update. As a matter fact, I just asked Siri if he could notify me before they go to shut down my phone and he said no problem he would add it to the alerts. I’m not anywhere near Tex as most of you as you’re probably my children’s and grandchildren’s age so get into settings and see if there’s something there I know you can find something your are the smartest generation if I may proudly say so?👍🤭

Hello everyone I am also face same problem in 15 pro max . It’s suddenly off and it’s on in 3/5 seconds automatically. Last few days it’s happened with me . What’s is solution this ? I buy it 1 week .

The same thing is happening to me except I can turn it back on but whenever i go to continue using my phone it shuts back off again. This only started happening after I updated my iphone 13 to Ios 17.3. What is happening and is there anyway I can fix it by myself before I make an appointment to bring it to Apple?

I have an iPhone 14 Pro, and did the 17.4 update last night. Now the phone will randomly shut down. I can do the volume up/down --> power button hold restart. But it invariably just ends up shutting down again when the phone autolocks. Can someone at Apple please guide on how to fix this?

Same thing here, iPhone 14 Plus keeps shutting down many times in a day for 2-3 days already. Since iOS 17.4.1 I got some glitch, like the the clickable stuff on a web page does not respond at all when clicking on it. Sometimes I was not able to scroll down a page in safari, Apple News, etc.

those glitch happened in the past weeks.

Now it keeps randomly rebooting, more when Facebook or messenger are opened and if I look a video ou listen to a podcast, it occurs more.

please apple fix that asap.

thanks!

My phone started doing this today and won't stop. It won't connect to wifi or 4G so I can't access my bank account, make or receive calls, anything. Went to a Genius Bar and they were of no help. I'm so stressed, I can't afford a new phone. Is it an iOS 17.4 issue? My phone is less than a year old

I have a iPhone 13 and the exact same thing keeps happening to mine. All started after updating to 17.4.1 now it wants me to update to 17.5.1 is it worth doing this or is it only going to get worse ? This is the fourth time on I phones that I’ve had an update and it’s wrecked the phone. I swore to god that is never buy another.

I have the iPhone 13 and I’ve only had it for a year and a half. I’m on my phone a lot which I guess probably isn’t great? I’m not tech savvy in the slightest so I’m sorry. But for the past two weeks or so my phones shut off twice in the most inconvenient times. I’d pick up my phone and the screen would be black and no matter how much I tapped the screen or pressed buttons it refused to turn on. I thought I had somehow broken it until I switched on and off the little silent mode button on the side of the phone and it still made the vibration noise. After a good five minutes of freaking out and pressing buttons the phone finally turned on as if nothing happened. It did it again tonight when my phone was at full charge and it did it when it was not at full charge and I didn’t know why it was acting this way. I guessed it was maybe because I have no storage on my phone or because I had somehow broken it but neither option should happen on a phone this new. Anything I could do to help fix it ?? I can’t go out of my way to spend money as I’m just a student, so I’m hoping there’s some free maintenance perhaps I could do myself to make using my phone less of a hassle 😅😅

I am using an iPhone 13 and I have the same issue, my phone suddenly shut off and the battery goes back to one percent when it turns on and it stays on one percent and suddenly it shuts off, and it comes back with the percentage. the battery was . right now as I’m writing this comment my battery is one percent but my battery was charged up to 75% earlier. Please I need a fix for this
