The Duplicates album is missing from Photos for one of three reasons: your iPhone runs an iOS version older than 16, it has not finished indexing your library, or it finished and found no duplicates. Indexing only runs while the iPhone is locked and connected to power, and Apple says it can take anywhere from a short while to several days, depending on your library and what else the phone is doing in the background. Apple says that while indexing runs, Photos shows a status message at the bottom of Library. If indexing is done and the album is still absent, the album only appears when duplicates exist, so there is nothing to merge.
The steps below are for iOS 27. Where iOS 26 or earlier differs, we say so.
Where the album should be
On iOS 26 and 27, open Photos, go to Collections, scroll down to Utilities and look for Duplicates. On iOS 16 and 17, it sits under Albums > Utilities. Duplicates arrived in iOS 16, so an iPhone on iOS 15 or earlier does not have it. Check your version in Settings > General > Software Update and update if you can.
Check whether your iPhone is still indexing
Photos has to scan the whole library before it can list duplicates. Apple says this scan runs only while the iPhone is locked and plugged in.
- Open Photos > Library and scroll to the very bottom. Apple says a status message there shows that indexing is still running. On our test iPhone, where indexing had finished and the Duplicates album was already there, the bottom of Library showed nothing about indexing.
- If it is running, plug the iPhone into power, lock it and leave it, for example overnight. Apple's requirement is a locked iPhone on power, so that is the state to give it.
- Check again the next day. A large library can take several days.
Apple does not say anything about Wi-Fi, a minimum number of photos or a maximum number of duplicates, so we do not either.
If indexing has finished and there is still no album
Then your iPhone did not find any duplicates. Apple's guide says the collection does not appear when there are none. You can rely on that: a missing album after indexing is a result, not a fault.
Two things are worth knowing from here.
- Apple does not define "duplicate". Its documentation says Photos detects duplicate photos and videos, but not whether that covers shots that only look alike, such as burst frames or two takes of the same scene. If your library is full of near-identical photos and Duplicates is empty, they were probably not counted. Our guide to deleting similar photos on iPhone covers the options.
- Merging frees space only after one more step. Merge keeps one copy of each set and moves the others to Recently Deleted, where iOS holds them for 30 days. Empty that album if you want the space back right away.
Where PhotoGO AI fits
Disclosure: PhotoGO AI is our app. It does not depend on Photos' background indexing. It scans the library itself and groups duplicate and near-identical shots side by side, so a library that Photos reports as having no duplicates can still show groups of similar shots there. You decide what to delete, and deleted photos go to Recently Deleted like any other deletion. Scanning is free; the number of free deletions is limited.
FAQ
Why isn't the Duplicates album on my iPhone?
Either the iPhone is on iOS 15 or earlier, it has not finished indexing the library, or it finished and found no duplicates. Indexing runs only while the phone is locked and connected to power.
What iOS version do I need for the Duplicates album?
iOS 16 or later. On iOS 26 and 27 the album is under Collections > Utilities; on iOS 16 and 17 it is under Albums > Utilities.
How long does it take for Duplicates to appear?
Apple says anywhere from a short while to several days, depending on library size and background activity. Keep the iPhone locked and plugged in.
Does Merge delete my photos?
Merge keeps one copy of each set and moves the other copies to Recently Deleted, where they stay for 30 days before iOS deletes them permanently.
Does Duplicates find similar photos, such as burst shots?
Apple's documentation does not say. It describes the album as finding duplicate photos and videos without defining the term, so check what your own album lists.
