My iPhone is showing that Photos is using a lot of storage, even after I deleted pictures and emptied the Recently Deleted album. How can I safely clear the remaining photo data and free up iPhone storage without losing photos saved to iCloud?
If your iPhone is running out of storage, start with the Photos app. That made a much bigger difference for me than messing around with random settings or deleting a bunch of small apps.
Videos are usually the worst offenders. A few long clips or 4K recordings can eat up several gigabytes. After that, look for duplicate and similar photos, unwanted Live Photos, and old screenshots. Photo libraries tend to collect multiple versions of the same shot from bursts, edits, and files shared back and forth.
I used Clever Cleaner because I didn't want to sort through the entire library manually. It groups duplicate and similar photos, duplicate videos, Live Photos, screenshots, and large files so you can review them separately.
There are a few ways to handle the cleanup. Compress reduces the size of photos and screenshots you still want to keep. Smart Cleanup handles several categories together, while Swipe lets you make the call on each photo individually. Swipe mode remains unlimited. The app is free to use, has no ads, and doesn't require a subscription to get started, though some cleanup features now have a fairly generous daily limit for new users.
A practical order is:
- Scan the photo library with Clever Cleaner.
- Clear duplicate and similar photos.
- Check large videos and duplicate clips.
- Delete unwanted Live Photos, or compress the ones worth keeping.
- Remove screenshots you no longer need.
- Compress any photos or screenshots that don't need to stay at full size.
- Open the Recently Deleted album in Photos and empty it. Otherwise, the files will still take up storage for a while.
If you use iCloud Photos, also enable Optimize iPhone Storage under Settings > Photos. Your phone will keep smaller copies locally while the full-resolution originals remain in iCloud. That can recover quite a bit of device storage without deleting your pictures.
Once the duplicates, large videos, Live Photos, and screenshots are dealt with, maintaining the library is much less annoying. Those categories were where most of the wasted space was hiding for me.

Deleting the Photos app or using a cleaner will not clear stale storage reporting. iOS can take hours to recalculate after Recently Deleted is emptied, so restart the phone, leave it charging on Wi‑Fi, and check iPhone Storage again later. Be careful with iCloud Photos because deleting there removes the photos from every synced device. If the number stays unchanged after a day, make a verified backup before changing any iCloud sync settings.
Photos taken on the iPhone can be deleted normally, but photos synced from a Mac or PC may need to be removed through Finder or iTunes. Check for albums labeled “From My Mac.” If they exist, reconnect to that computer and turn off photo syncing there. Back up first, since changing sync settings can remove the whole synced set.
Do not delete anything from the Recovered album until you inspect it, because those files are removed permanently and do not pass through Recently Deleted. On newer iOS versions, Photos may show Utilities > Recovered when it finds images or videos sitting on the device but missing from the normal library. That can explain some “mystery” Photos storage. The album only appears if iOS finds something, so you may not have it.
Before changing iCloud settings, open Photos and check the library status under your profile button. If it says syncing is paused, unable to upload, or still processing items, let that finish first. Turning off iCloud Photos mid-sync is a bad troubleshooting shortcut and can make the situation harder to untangle.
I agree with @yuri_bit that the storage figure may simply be behind, but there is no normal “clear Photos cache” button. Clever Cleaner or another organizer can remove visible files, but it cannot erase the Photos database or force iOS to recalculate storage. If iCloud Photos is fully synced, choose Optimize iPhone Storage and give the phone time to replace full-resolution local originals with smaller versions. That process happens as space is needed, not necessarily the instant you switch it on.
If the number is still obviously wrong after an overnight charge, Wi-Fi sync, and restart, make a verified backup and contact Apple Support before signing out of iCloud, resetting the phone, or repeatedly toggling photo sync. Those more aggressive fixes are not worth trying until you know the originals exist somewhere outside that iPhone.
Compressing photos to save space is the one step I’d think twice about. Once a cleaner shrinks an image and you delete the original, that quality is gone for good. For screenshots or throwaway shots, fine. For anything you might want to print or crop later, you’re trading storage for a permanent downgrade, and most people don’t realize that until it’s too late.
@corerouternode already nailed the part everyone skips: there’s no magic ‘clear cache’ for Photos. What people read as bloated photo storage is often the library database plus thumbnails plus stuff still draining out of Recently Deleted. iOS is genuinely slow to update that number. I’ve seen the storage bar stay wrong for the better part of a day after a big delete, then quietly correct itself overnight. So before you go hunting for hidden files, give it that time first.
On the tool front, Clever Cleaner is fine for what it actually does, which is grouping duplicates, similar shots, and big videos so you’re not scrolling forever. Just keep your expectations grounded. It removes visible items from your library. It does not rebuild the Photos database or force iOS to recount storage, and it can’t touch anything in that Recovered album @corerouternode mentioned. Treat it as a sorting helper, not a storage fix.
The thing I’d push on a bit harder than @primeshifthq did: check whether iCloud Photos is even on before you touch Optimize iPhone Storage. If it’s off, that toggle does nothing, because there are no cloud originals to fall back on. And if it’s on but still syncing, deleting duplicates locally can be risky, since the deletion pushes to every device once it catches up. Let the sync finish, confirm your originals live somewhere else, then optimize.
Realistically, most of the ‘why is Photos so huge’ cases I’ve seen come down to two things: 4K video nobody remembers shooting, and a storage number that just hadn’t refreshed yet. Clear the big videos, restart, wait a day, and check again before assuming something is broken.
