Quick answer: Old iPhone backups can be deleted from Apple Devices, iTunes, or Finder-style backup management tools. Keep the latest backup if you rely on local restores.
Why this uses C drive space
Local iPhone and iPad backups can be many gigabytes and are often hidden under the user profile.
Safe cleanup steps
- Open Apple Devices or iTunes if installed.
- Find device backup management.
- Delete old backups you no longer need.
- Keep a current backup before major iOS updates.
- Consider iCloud or an external drive for backup strategy.
What to avoid
Do not delete backup folders manually unless you know which device and date each backup belongs to.
