I’m trying to clear out a large batch of screenshots in the native iPhone Photos app, but deleting them takes much longer than I expected. The app lags, hangs, or feels unresponsive while I remove multiple images, and it’s slowing down a simple cleanup. I need help figuring out whether this is normal, a storage issue, or a fixable iPhone Photos app performance problem.
I ran into this mess on my own phone. Screenshots stacked up fast, way faster than normal photos. You tap two buttons, move on, and months later your library is stuffed with login codes, order pages, maps, random memes, and stuff you meant to send once. The file size adds up too. I saw screenshots sitting anywhere from around 200 KB to over 2 MB each, depending on the iPhone and iOS build. On a Pro Max, it got ugly fast. A few thousand of them ate several GB before I noticed.
The Photos app does not help much. You do not get file size sorting. You do not get a clean view of how much space each screenshot is taking while scrolling. So if your goal is storage, you end up deleting blind.
Why I started with Clever Cleaner
If your main goal is getting storage back, Clever Cleaner gives you the stuff Photos hides. The app is free, no ads, no paid wall, which I did not expect for this type of app. In the Screenshots tab, each thumbnail shows the exact file size right there. You know what you are removing before you hit delete.
There is also a Heavies tab, and this part helped more than I thought it would. It sorts your whole library from the biggest files down. So the bloated stuff rises to the top first. Full-page screenshots, giant saved images, HDR shots, weird oversized captures, all of it. You stop wasting time on tiny files and start with the ones doing the damage.
The Similars tool is another thing worth pointing out. iOS 18 catches exact duplicates, but it misses those almost-the-same shots, like when you took five screenshots trying to grab the right frame. Clever Cleaner groups those together with AI, lets you keep the best one, then wipes the extras in one go. On my phone, this cleaned up a lot more than duplicate detection in Photos ever did.
If you want a look at how it works, here is the link:
If you are staying inside the Photos app
Open Photos, go to Albums, scroll down to Media Types, then open Screenshots. On iOS 18, Apple shuffled things around a bit, so you might need to swipe across the Media Types row to see it. If you want quicker access next time, go to the bottom of Albums, tap Customize and Reorder, then move Media Types higher up.
Inside Screenshots, hit Select. Then tap one thumbnail and drag across and downward to grab a bunch at once. This works fine, but I hit freezes when I got greedy. If your free storage is already low, deleting hundreds at once can lock up Photos for a while. I had better luck doing batches of 50 to 100. Slower, yeah, but less chance of the app choking.
The part people miss
Deleting screenshots from the library does not free space right away. They get moved to Recently Deleted under Utilities and sit there for 30 days. If you need the storage back now, open Recently Deleted, tap Select, then Delete All. That is the step where the space comes back for real.
How I stopped the pileup later
For throwaway screenshots, the Copy and Delete option is way better than saving everything. After you take a screenshot, tap the preview, hit Done, then pick Copy and Delete. The image goes to your clipboard, so you paste it into a text or email, and nothing lands in Photos. I use this for one-time codes, shipping confirmations, temp info, stuff I know I will never need again after ten seconds.
If you wiped the wrong thing
First stop is Recently Deleted. If it is still there, recovery is easy. If you already emptied it, your best shot is dedicated recovery software. I had better results with that route than digging through backups and hoping iCloud saved the right version at the right time.
Once I cleaned mine out, the storage bar dropped and the phone felt less clogged up. Apps stopped whining about space. Photos opened faster too. Not magic, but enough to notice.
Photos slows down because delete is not one action on iPhone. It updates the library database, syncs changes to iCloud Photos, refreshes thumbnails, runs face and object indexing, then moves items to Recently Deleted. If you delete 500 screenshots at once, you’re asking the app to do 500 file ops plus library cleanup. On older iPhones, or when storage is almost full, it bogs down fast.
I’d push back a bit on @mikeappsreviewer here. File size matters, but lag is often more about library management than screenshot size. A 300 KB screenshot and a 2 MB screenshot both still trigger the same cleanup pipeline in Photos.
What helped me most:
- Plug in the phone and keep it unlocked.
- Turn off Low Power Mode.
- Delete in smaller chunks, like 30 to 50.
- Wait a few seconds between batches.
- If iCloud Photos is on, do it on stable Wi-Fi.
- Restart Photos, or reboot the phone if it starts to hang.
Also check iPhone Storage. If you have under 5 GB free, iOS gets janky fast. That part gets missed alot.
If your goal is faster cleanup with better sorting, Clever Cleaner is worth a look since Photos is clumsy for bulk review. I found this useful too: see how Clever Cleaner handles screenshot and photo cleanup.
The lag is normal-ish. Annoying, but not rare.
