Skip cleaner apps. Use a simple monthly routine.
- Open Photos, sort by “Screenshots” and delete by month.
- Sort Photos by “Videos”, sort by size, remove the biggest first.
- In Messages, delete old conversations over 1 year in Settings > Messages > Keep Messages.
- In Settings > General > iPhone Storage, remove unused apps with “Offload App”.
- Move big videos to iCloud, Google Photos, or a laptop, then delete local copies.
Set a calendar reminder so you repeat this every 4 to 8 weeks.
