To take photos again right now, open Photos > Albums > Recently Deleted, tap Select, then Delete All to reclaim space iOS is still holding. Then delete one or two large videos in Settings > General > iPhone Storage > Review Large Attachments (or the Photos app). You usually only need a few hundred MB free for the camera to start working again.
TL;DR
- The camera blocks shooting when free space drops below roughly 200-500 MB.
- Emptying Recently Deleted in Photos is the fastest single win.
- Deleting one 4K video (often 300 MB to 2 GB) can be enough on its own.
- Photos you delete stay recoverable for about 30 days before they're gone.
- For a lasting fix, clear duplicates and screen recordings, not just one file.
Why does my iPhone say storage is full when I try to take a photo?
iOS refuses to capture when it can't guarantee room to save the file. A single 4K/60 video uses around 400 MB per minute, and Live Photos and ProRAW are large too, so the camera needs headroom before it commits a shot. When free space falls below a few hundred megabytes, you get the "Storage Almost Full" or "Cannot Take Photo" warning instead of a saved image.
The quick truth: you don't need to clear gigabytes to shoot again. You need to push free space back above the camera's threshold, which is usually a few hundred MB.
How do I free a few hundred MB in two minutes?
Do these in order and stop as soon as the camera works:
- Empty Recently Deleted. Go to Photos > Albums > Recently Deleted, tap Select, then Delete All. Deleted photos sit here for ~30 days and still occupy storage until you clear them.
- Delete one or two big videos. Open Settings > General > iPhone Storage, scroll to Photos, and review your largest items, or sort by size in the Photos app. One 4K video can free 300 MB to 2 GB.
- Clear the second Recently Deleted. After deleting those videos, return to Recently Deleted and empty it again so the space is actually released.
That's typically enough. Reopen the camera and take a shot to confirm.
Where does iOS stop helping?
Natively, iOS shows you a sorted iPhone Storage list and offers Offload Unused Apps and recommendations. That's useful, but it stops at the obvious. It won't find near-identical burst shots, blurry frames, oversized screen recordings, or the dozens of duplicates that quietly add up. iOS treats every photo as worth keeping; it never tells you which ones are redundant.
That gap is why "I deleted stuff but it filled up again" happens. If your storage looks full with nothing obvious to remove, see iphone storage full but nothing to delete what's actually using it.
What if deleting photos didn't free enough space?
Two common reasons:
- You didn't empty Recently Deleted. Deleting a photo only moves it; the space returns when that album is cleared.
- Photos aren't your biggest user. Check Settings > General > iPhone Storage and look at the top of the list. If "Other," apps, or attachments dominate, target those instead.

Will I lose my photos if I delete them?
No, not immediately. Anything you delete moves to Photos > Albums > Recently Deleted and stays recoverable for about 30 days. If you sync to iCloud Photos, confirm the originals have finished uploading before you mass-delete, otherwise you may remove the only copy. When in doubt, back up to iCloud or your computer first, then delete.
FAQ
How much free space does my iPhone need to take a photo?
Usually a few hundred MB. The camera checks for enough room to save the file plus overhead, so freeing 300-500 MB is normally enough to start shooting again, especially for standard photos rather than 4K video.
Why does my storage fill up again right after I clear it?
Most often because Recently Deleted wasn't emptied, iCloud Photos re-downloaded originals, or large videos and duplicates are still present. Clearing one file rarely fixes a phone that's chronically full; you need to remove the biggest and most redundant items.
Does Optimize iPhone Storage help me take photos?
It can. Settings > Photos > Optimize iPhone Storage keeps smaller versions on the device and full-resolution copies in iCloud. It frees space over time but won't instantly clear a full phone, so do the manual steps above first.
If your camera keeps stalling on "storage full," the real fix is removing the redundant videos, duplicates, and screen recordings iOS ignores. Cleanor for iPhone scans your library, surfaces the biggest and most duplicated files, and clears them in a few taps so you can fix a full phone fast.
