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

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 happened tonight. It made a noise as though something had shorted, the screen froze with a series of large pink and green pixels and the last image on the screen was shifted about half an inch off center (to the right). Then it shut off. It booted up fine, and the device didn't feel like it had overheated. No smell of burnt plastic or metal, no ozone scent. Never seen anything like it.

Same as all of you. Was in bed with phone on charger. Picked it up on what looked like a full charge, started to play a game, and a loud crackling/sparking noise along with instant black screen with a few sparks of light Arron’s the edge of the phone then rebooted instantly and now phone seems fine. Scared the crap out of me. Thought maybe a surge through the wire fried the phone. But no heat and phone works like nothing happened now. Afraid to plug it back in or sleep near it now. Any ideas?
