Find Duplicate Photos on iPhone is easiest when you use the iPhone feature that directly controls the task instead of changing several unrelated settings.
- Open Photos.
- Scroll to the Utilities section and open Duplicates if it appears.
- Review each detected pair or group.
- Tap Merge for duplicates you want Photos to combine.
- Check Recently Deleted before permanently removing anything.
The Duplicates collection appears only after Photos has identified duplicate items, which can take time. Merging keeps the highest-quality version and relevant data.
Photos analyzes the library in the background, so a newly imported duplicate may not appear immediately. Before merging a large number of items, make sure your important photo library is synced or otherwise backed up.
When finished, verify the result in the app or setting you changed before making additional adjustments.
Before changing anything else, compare the result with the original goal and check the related setting or app once more. This helps separate a setting problem from account, network, device, or app-specific behavior and avoids undoing a change that is already working correctly.
