How do you merge duplicate photos on the iPhone?
In short
In the Photos app, scroll to the bottom of the albums, open Duplicates under "Other", select all and merge. The best quality is kept in each case.
Step by step
- Open the Photos app and go to Albums.
- Scroll all the way down to "Other" and open "Duplicates".
- Tap "Select".
- Select all photos. You don't have to go through them one by one.
- Tap "Merge".
You need this if your storage is full because too many photos and videos have piled up. According to Jen, the Photos app keeps the photo or video with the best quality in each case. On her phone, the app found 518 duplicates.
