Only because I think it’s a travesty when this dig goes unchallenged:
Batteries get old and have voltage drop at high current; that is called physics. Chips reset below a design voltage; that is also called physics. Slower phones are better UX than rebooting under load. Next time, just say “I hate Apple” rather than repeating debunked stuff.
My iPhone X didn't have shutoff issues, but the battery did swell enough to push out the screen, which Apple replaced for free even with an expired warranty.
Where is I hate apple coming from ? I was merely referencing this well known case
The window in the normal person’s mind for “they’re doing this on purpose” is probably the month of the event announcement, plus the month the event happens in, and then the month afterwards is when the phones ship and friends start getting them. That’s a solid 25% of the year that would look suspicious to a conspiracy theorist.
