The Duplicates album only appears after the Photos app has indexed your library and found duplicates. On iOS 26 and 27, look in Photos, then Collections, then Utilities. If Duplicates isn't there, your iPhone either hasn't found any duplicates or is still indexing your library. Apple says duplicate detection requires your iPhone to be locked and connected to power, and can take up to a few days.

Apple doesn't describe a way to speed this up. It only says detection requires your iPhone to be locked and connected to power.
If there's no status message and the album still isn't there, Photos hasn't found any duplicates in your library. That doesn't mean there's nothing to clean up. Apple describes the album as finding duplicate photos and videos and doesn't publish its matching rules. The album is about copies, so it isn't built for picking the best of several similar retakes, or for finding blurry shots and photos where someone blinked.
PhotoSlimmer is a photo cleaner for iPhone and Android that groups duplicates and similar shots, and finds blurry and closed-eye photos. The analysis runs on your phone with an AI model built into the app, so nothing is uploaded, and it never deletes anything on its own. You can delete up to 50 photos a day for free, and a one-time purchase removes the limit ($9.99 in the US). There is no subscription.

Either Photos hasn't found any duplicates, or it's still indexing your library. Apple says detection needs your iPhone locked and connected to power, and can take up to a few days.
Open Photos, tap Collections, tap Utilities, then tap Duplicates. On iOS 18, tap Utilities, then Duplicates. On iOS 17, tap Albums, then tap Duplicates below Utilities.
Apple says it could happen quickly or take up to a few days, depending on your library size and other background tasks. Keep your iPhone locked and charging.
Apple doesn't describe a way to speed it up. Leave your iPhone locked on a charger and check the status message at the bottom of Library. If no duplicates are found, the album won't appear at all.
