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

iPhone 12 Pro, latest update. Was using Instagram and got the crackling/bright flash and then phone blacked out. Couldn’t do anything. Was on charger not completely charged yet. Unplugged it and the phone automatically rebooted itself. At first all my texts were gone and came back 5 minutes later. My phone was a year old December 2021 & like everyone else paid a fortune for it. Apple has not commented or addressed this issue yet. Why?

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.

just happened to me a minute ago. I was on FaceTime with my gf why charging my phone and I was just about to fall asleep when it cracked, purple and green screen glitched, and reboot. I’m guessing the problem has something to do with live-streaming type things. The only thing we can look forward to in this issue is Apple to take care of it.

If you have a Twitter account send Apple Support a tweet and report your problem. I did this in February and they responded immediately. Not very helpful but at least they responded 🤷‍♀️ I told them to read their community forums because it wasn’t just me. I’ve gotten no further response. Maybe if we all posted on their Twitter account 🧐

Same as everyone else, I’m also seeking for answers as this literally just happened to me as well for the 1st time with my IPhone 12 Pro Max I’ve had for years. The crackling sound happened out of nowhere with about 30% battery, then my phone screen turned completely black. As it happened, I instantly felt electrically shocked on my hand as I was watching a YT video which really concerned me. I rapidly tossed my phone across the room after I felt the shock because I genuinely felt like it would potentially burst.

Happened to me 5 minutes ago on my 1 month old iPhone 12 mini.


The screen froze while web browsing, the frozen screen looked like one of those static you get on an old TV, accompanied by a loud crackling sound.


Never had this issue with my previous iPhone 8. Freaked me out to be honest, I've only been using it for a month!

This just happened to me I’ve only had this new max pro 12 for a couple months. I was playing a game this electrical cracking noise then the screen went weird … the phone rebooted it seems fine now but this phone is too expensive to be having these issues especially when it’s brand new and I’m not even on it a lot. After this I’m afraid to even leave it on the charger unattended. Oh and do not know about anyone else but the chargers for this phone suck it already has a short in the cord so had to get a new one.

I also faced this issue ! I already claim warranty and the Apple Authorities Service Centre said that they already change a new Rear System for me. I just get the phone yesterday (17/06/2021). But the problem still there, I play a video games then suddenly an electric sound come out then the screen become black again, the phone restart back after few second lol… Who already solve this issue? Can you please contact me?
