My iPhone restarts itself while watching a twitter video

Hi everyone, Can anyone help what is the whole thing that cause this issue to my iPhone? I just watch twitter videos and suddenly my phone turn off (black screen) and then reboot by itself. When the phone suddenly turn off it plays weird sound (It's like you're watching TV and then unplug the outlet, so there's a shorting sound) My iPhone is 15 Pro bought it at november 2023 and rarely used, i just got 60 charge cycles. Is this restart by itself is normal? Thank you
