My iPhone storage is completely full because of thousands of photos and videos, and deleting them doesn’t seem to free up space right away. I already removed pictures from the Photos app, but my storage still looks full and I need the space back as soon as possible for updates and everyday use. What’s the fastest way to permanently delete all photos from an iPhone and actually reclaim the storage?
I ran into this with an iPhone packed with around 20,000 photos. Storage warnings nonstop. Photos would hang the second I tried to clean anything up. The annoying part is Apple still doesn’t put a plain “Delete All” option in the main library, so if you don’t know the order, you waste time and get nowhere.
Why your storage stays full after you delete stuff
This trips up a lot of people. When you delete photos, iOS does not remove them right away. It moves them into Recently Deleted, where they sit for up to 40 days. Until you clear that folder, your storage number often won’t budge.
If you want the space back now, do this:
- Open Photos
- Tap Albums
- Scroll down to Recently Deleted under Utilities
- Tap Select
- Tap Delete All
If you skip Recently Deleted, the phone still treats those files like they exist.
Why Photos starts choking on huge libraries
Small batches are fine. Once you get into the thousands, drag-select gets ugly. I saw lag, random freezing, sometimes the app bailed out entirely. Even newer iPhones do this when storage is almost maxed.
One thing helped me. I removed a big app first, usually a game or some bloated social app. That gave iOS enough free space to finish deleting photos without locking up.
If the touchscreen part is making you nuts, use a computer instead.
On a Mac, plug in the iPhone and open Image Capture. You can select everything and delete it fast.
On Windows, open the DCIM folder in File Explorer. Same idea, though in my case it was hit or miss depending on drivers.
A cleaner way to deal with a giant photo library
Past a few thousand files, I stopped fighting the stock Photos app. Most cleanup apps in the App Store are loaded with paywalls or subscription nags. Clever Cleaner stood out because it was free, had no ads, and didn’t block features behind payment screens.
What I did inside it:
- Open the Heavies tab. It sorts your library from biggest file to smallest, so the storage hogs show up first.
- Start at the top. A few huge videos often eat more space than thousands of small photos.
- Move to Similars. It groups near-duplicate shots, the five or ten versions of the same pic you took back to back. You keep one and dump the rest.
- Check Screenshots. Each thumbnail shows the file size, which makes it easy to cut junk fast.
- Everything stays on the device. Nothing gets uploaded out somewhere else, which mattered to me because screenshots and photos often include private info.
The useful part was Heavies plus Similars together. Random bulk deletion is slow and sloppy. Going after the biggest files first works better.
One thing I’d check before deleting a lot
If iCloud Photos is on, deleting from the iPhone also deletes from iCloud and your other Apple devices tied to the same account.
If your goal is to clear phone storage without losing the photos for good, go to Settings, then Photos, then look for Optimize iPhone Storage. That keeps smaller versions on the phone and leaves the full originals in iCloud.
If you already copied everything to a PC, Dropbox, or Google Photos, then wiping the phone library is less risky. Still, I’d confirm the backup finished before touching delete. I learned not to trust “syncing” messages till I checked the files myself.
After you finish, clear Recently Deleted. That’s the step where the storage bar finlly starts moving.

If storage still looks full after you deleted photos, check two things Apple hides in plain sight.
First, restart the iPhone after emptying Recently Deleted. I know @mikeappsreviewer covered the trash step. He’s right on that. But iOS storage math often lags behind until a reboot. I’ve seen 30GB show as “used” until the phone restarted, then it dropped.
Second, look at Settings, General, iPhone Storage, Photos. If the number there stays huge, your phone is often stuck indexing the library. Leave it plugged in, on Wi-Fi, screen locked, for 30 to 60 minutes. Storage sometimes updates after background cleanup finishes. Annoying, but true.
If you want fast results, target videos first. Ten 4K videos often eat more space than 3,000 photos. Sort and remove the largest items before mass deleting. Clever Cleaner helps with this because it surfaces heavy files and duplicates faster than the stock app when the phone is lagging.
Also check Messages, Files, WhatsApp, Instagram cache, and downloaded Netflix or Spotify media. A lot of people blame Photos, but 20GB to 50GB is often hiding elsewhere too.
If you want a second opinion on the app, this thread sums up user feedback well:

One more thing. If iCloud Photos is on, I don’t fully agree with deleting everything from the phone as the first move. It turns into an all-device wipe. Safer to confirm what lives in iCloud, Google Photos, or your computer frist.
One thing I’d add to what @mikeappsreviewer and @espritlibre said: sometimes Photos is not the real problem anymore, the storage category just hasn’t recalculated yet. iPhone storage reporting is weirdly stubborn.
What worked for me was this:
- Turn off Low Power Mode
- Plug the phone in
- Connect to Wi-Fi
- Restart after emptying Recently Deleted
- Leave it locked for a while so iOS can finish cleanup/indexing
I actually disagree a little with the “delete everything at once” approach if the phone is already choking. On super-full iPhones, giant bulk deletes can stall and just make Photos act dumb. Deleting the biggest videos first is often faster and frees space imediately. That’s where Clever Cleaner helps, because it surfaces the worst offenders without making you scroll for ages.
Also check this stuff before assuming Photos still owns all the space:
- Messages attachments
- Files app downloads
- Safari offline reading list
- WhatsApp media
- Music/Netflix/Spotify downloads
And if you want a visual walkthrough, this video guide to free up iPhone photo storage fast is easier than guessing through menus.
Short version: empty Recently Deleted, reboot, wait for storage to recalculate, then hunt videos and attachments. That combo usually does it.
I’d add one thing the replies from @espritlibre, @shizuka, and @mikeappsreviewer only touched indirectly: check whether the space is being held by system snapshots and not Photos anymore.
This happens a lot after huge deletions. The library is gone, Recently Deleted is empty, but iPhone still shows storage as full because iOS is clinging to temporary caches, failed sync data, or restore logs. In Settings > General > iPhone Storage, if “System Data” suddenly looks bloated, that is your clue. I actually disagree with the idea that waiting always fixes it. Sometimes it does not.
What usually works faster:
- delete any pending iOS update file
- remove and reinstall one large streaming or social app with huge cache
- make sure there is no half-finished iCloud sync
- if storage is still stuck, do a backup and restore
That last one is the nuclear option, but it is often the only way to force iOS to recalculate honestly.
About Clever Cleaner: useful if Photos is too laggy to sort manually.
Pros
- surfaces large videos and duplicate-like shots fast
- easier than fighting Apple’s Photos UI on a full phone
- good for trimming junk before a full wipe
Cons
- still depends on iOS deletion behavior, so space may not appear instantly
- not magic if the real problem is System Data
- some people may prefer doing everything on a computer for total control
So my take: if Photos was deleted already and space still has not come back, stop staring at Photos. Check System Data next. That is where the lie usually is.
