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

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.

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. I was reading an article on Facebook, no music or video playing or anything, when suddenly *CRACKLE* and it turned off… I was able to turn it back on, and the battery is at 42%, which is where I think it was before it turned off, but one of the earlier comments also mentioned 42% battery power so I’m wondering if it’s a specific problem that happens around that percentage…in any case, I don’t see any signs of lingering problems, but I still have no idea why it happened in the first place.

Exact same thing has just happened to my brand new week old 12Pro Max.


Turning on alarm, phone plugged in. Loud crackle and pop sounding like a power shortage, blue and lilac flashes of light. Phone turns off and restarts.


Not overheated. Absolutely terrifying. Will be taking this to a store tomorrow seeing that you’ve all had no response on this for over a year!
