Thank you sooo very much ! for me just deleting the Voice Memo freed up 252GB space ! Absolutely insane. I spent countless hours over this issue. Thank you thank you!!!

Indeed , I was premature in leaving the comment, deleting the voice memo app only solved it temporarily . 'Others' back to ~230 GB. Aready running ios 15.6. I'm seriously distressed now - this is a new phone and I failed data transfer uncountable times - until I finally hit the underlying issue - this 'others' space. Already spent unlimited nighs over this last whole month and my new phone (iphone 13) remains practically unusable. Any fresh tips please? I'm totally at my wits end.
