also wanted to say don’t sleep on app cache!
lots of apps (esp stuff like Instagram, TikTok, even Maps) stash a ton of data
and if you use WhatsApp or Telegram, check their storage settings
they save everything, every pic, video, voice note, doc…
i ended up deleting like 3gb just from WhatsApp chat media alone 🙃
sometimes if there’s no built-in cleanup option, I just delete the app and reinstall it fresh, easy space win
you can also try an iPhone cleaner app like Remo Duplicate Remover
These don’t touch cache, but if your photo library’s a mess they can definitely can help clean up
