Loud crackling noise then iPhone 12 shut off

I was scrolling through tiktok at a low volume when my phone randomly made a loud cracking sound and then shut off. It almost sounded like an electrical short. Phone rebooted on its own and seems fine. Very strange for a brand new Apple iPhone 12....

iPhone 12, iOS 14

So what I've determined is we've all had exactly the same issue, no one knows what it is, and Apple hasn't replied here but I went ahead and did a support chat and here's what I got:


  • Okay, please be assured that your iPhone is secured and the iOS that you have on your iPhone has the best security in the market.
  • Let me explain a device restart can be caused by the App that you are using at that time or any system issue.
  • All the discussion and the feedback are checked by the Apple engineers on a regular basis. Also any issue that is occurring or needs to be checked is also escalated to the team so they are aware of any system issue and work on it to resolve it.


That's as far as I got.

The same thing just happened to me. I have an iPhone 12 Pro Max. Was just scrolling through FB Market place and this loud crackling/static sound happens and half the screen is a pinkish white static like an TV static but pink/purple color instead of black and white. It froze for a few seconds then the screen went Black and a few seconds later the Apple logo popped up. It seems fine but couldn’t find internet for a few minutes. What was the result of this issue. Is this something I should be worried about ?

Was using Instagram. Phone crackled, screen went black except for some pinkish/red pixelated dots at the top of the screen. Phone shut down and restarted on its own. I smelled faint burning smell.


I sleep with my phone under my pillow so I my alarm doesn’t disturb my partner. Not tonight. I don’t wanna die today.

My phone randomly made a spark noise then blacked out and the apple symbol came up I was so confused so when my phone turned back on I googled it and I fount out I charged it for a long period but it was only on charge for around 6-7 hours because I was out and my phone was fully dead and I’m concerned about my phone now cuz that’s the only time it has happened from over the 2-3 years of having this phone

It happened to me on my iPad Pro while I was playing Honkai Star Rail, I keep my charger plugged in on the regular so it doesn’t die but honestly I assumed it just overheated and restarted. But I’m seeing a bunch of you with Apple devices having the same issue and I’m starting to think that maybe I should have gotten a Samsung tablet instead. Procreate APKs most likely exist.

This happened to me not even 10 minutes ago, took phone off charge, went on Facebook reels then a loud crack type noise screen immediately went black for around 10 seconds (felt like 10 minutes because I was practically ******** myself thinking my phone had completely stopped working as I really can’t afford a new one, then it done the black screen with apple logo then came back on?phone isn’t hot or anything I’m going to the town with the Apple Store next week so I’m going to pop in and ask, I’ll edit this with an update if I can
