My iPhone’s photo storage seems unusually high, even after deleting pictures and emptying the Recently Deleted album. I’m looking for a safe, simple way to clear the photo cache without losing any important photos or videos.
There isn’t a separate photo cache you can clear on an iPhone. I wasted a lot of time looking for that option too, but Apple simply doesn’t provide one.
The storage shown for Photos under Settings > General > iPhone Storage is mostly your real library. That includes photos, videos, screenshots, Live Photos, edits, thumbnails, and files iOS needs to manage everything. Temporary files are handled automatically, so there’s no button that deletes only cached photo data while leaving the library untouched.
To get that storage back, you have to remove or shrink items in the gallery. I had thousands of photos and didn’t want to sort through them one by one, so I used Clever Cleaner. It picked out duplicate and similar photos, duplicate videos, old screenshots, and Live Photos I no longer needed.
My process was pretty simple:
- Give the app access to the Photos library and let it scan.
- Check its suggestions instead of deleting everything blindly.
- Remove unwanted duplicates, videos, screenshots, and Live Photos.
- Compress photos I wanted to keep but didn’t need at their original size.
- Open Photos and empty Recently Deleted. Storage usually won’t be reclaimed until you do that.
There’s also a Smart Cleanup option for handling several categories at once. The app is free to use, has no ads, and doesn’t require a subscription to start, though some cleanup tools have a daily limit for new users.
App downloads are a separate issue. If you mean photos and videos stored by WhatsApp, Messenger, Telegram, Instagram, or another app, those files may be sitting in that app’s own storage rather than your Photos library. You’ll usually need to clear them through the app’s storage settings. In some cases, reinstalling the app is the only practical way to remove all of its downloaded attachments.
So if Photos is using a lot of space, don’t keep hunting for a cache-clearing button. Clean up the library itself, compress large photos, or turn on Optimize iPhone Storage if you use iCloud Photos. Those options will free up far more space than trying to remove temporary files that iOS already manages.

Be careful: if iCloud Photos is enabled, deleting from the iPhone deletes those items from your other Apple devices too. Export anything important first, then clean up duplicates or large videos.
The annoying catch is that the iPhone Storage screen may keep showing the old Photos total for quite a while after a big deletion. That stale number can make you delete more than necessary because it looks like nothing worked.
After emptying Recently Deleted, restart the phone, connect it to power and Wi-Fi, then leave it locked for a few hours so Photos can finish syncing and recalculate storage. Check whether iCloud Photos says it is paused or still syncing before doing another cleanup.
@chasseurdetoiles is right that cleaner apps cannot wipe a hidden Apple photo cache. Something like Clever Cleaner can make finding duplicates and oversized videos less tedious, but it is still deleting or compressing library items. If the storage number remains stuck after a day, check Settings > General > iPhone Storage for Messages and social apps, since downloaded attachments often get mistaken for Photos storage.
Expect the safest cleanup to be a little boring: verify your backup, then delete actual library items. There is no risk-free “clear cache” switch. Keep in mind that iCloud Photos is syncing, not a separate backup. As @m3g4_widget noted, deleting on the phone can remove the same file everywhere.
Before giving a cleaner app full library access, check Photos’ built-in Duplicates collection and review videos, screen recordings, bursts, and screenshots. Those usually produce more useful savings than chasing thumbnails or temporary data. Clever Cleaner may speed up the sorting, but it still removes or compresses real files, so review its choices carefully.
Once Recently Deleted is empty, leave the phone charging with Wi-Fi and avoid repeatedly toggling iCloud Photos. That can create more syncing work without clearing anything.
Go in expecting the biggest chunk to be video, not photos. People fixate on the photo count, but a handful of long 4K clips or screen recordings will outweigh thousands of stills every time. Sort your library by size or file type first and you’ll usually spot the real problem in about a minute.
The @chasseurdetoiles point about there being no cache button is correct, and a tool like Clever Cleaner is fine for grouping duplicates and old screenshots so you’re not scrolling forever. Just don’t expect it to touch storage from other apps. If your number still looks bloated after clearing Photos, the Optimize iPhone Storage suggestion only helps when you’re on iCloud Photos, and it swaps full-res files for smaller versions rather than deleting anything, so it won’t free space if iCloud is off.
