TidyByte"iPhone Storage Full" or "Storage Almost Full" means your phone has run out of room. It is not broken, and nothing has been lost. Open Settings › General › iPhone Storage to see what is using the space, then delete in this order:
- Empty Recently Deleted.
- Remove or compress the biggest videos.
- Clear screen recordings and screenshots.
- Remove duplicates.
- Offload apps you do not use.
- Clear old message and mail attachments.
Leave System Data and the apps you rely on alone.
What does "iPhone Storage Full" actually mean?
Your iPhone has a fixed amount of storage, and it is close to full. When that happens the phone slows down, the camera may refuse to take photos or videos, apps cannot update, and iOS updates will not install.
That is all it means. Your photos, messages and apps are still there. Making room is a matter of removing things you do not need, in a sensible order, so you free the most space with the least risk.
How do I see what is using my iPhone storage?
Open Settings › General › iPhone Storage. Give it a moment; the numbers take a few seconds to calculate.
- The bar at the top shows how full the phone is and roughly what the space is made of: apps, photos, media, messages, System Data and so on.
- Below it, iOS may show Recommendations, such as reviewing large videos or offloading unused apps.
- Then comes the app list, largest first. Tap any app to see how much is the app itself and how much is its documents and data.
Look at the two or three biggest items. For most people it is Photos (which includes videos), then one or two apps, then Messages.
What should I delete first? The safe order
Work down this list and stop when you have the room you need. Everything you delete from Photos goes to Recently Deleted for 30 days; the space comes back when it is emptied.
1. Empty Recently Deleted
This is first because it costs you nothing. Anything already in there is something you decided to remove, and it is still counting against your storage.
- Open Photos › Albums, scroll to Utilities, tap Recently Deleted (on iOS 18 and later, Utilities is on the main Photos screen or the Collections tab).
- Unlock with Face ID, Touch ID or your passcode.
- Tap Select › Delete All (on newer iOS, tap the ⋯ button, then Delete All).

2. The biggest videos (or compress them)
Video is where the gigabytes are. A minute of 4K at 30 fps is roughly 170–190 MB, so a few long recordings can be more than all your photos combined.
- In Settings › General › iPhone Storage, tap Photos and look for Review Personal Videos. It lists your largest videos with sizes.
- Delete the ones you no longer need, or move the keepers to a computer or cloud storage first.
- For videos you want to keep on the phone, make a smaller copy instead. See how to make a video small enough to send and free up space without deleting your photos.
3. Screen recordings and screenshots
Screen recordings are videos, and they add up. Screenshots are small one at a time but people collect hundreds.
- Open Photos › Albums › Media Types › Screen Recordings.
- Tap Select, choose what you do not need, and tap the trash (bin) icon.
- Do the same in Media Types › Screenshots.
There is a faster way to clear a whole batch in delete all screenshots and screen recordings at once.
4. Duplicates and look-alikes
Since iOS 16, Photos finds exact duplicates for you.
- Open Photos › Albums › Utilities › Duplicates (on newer iOS, scroll to Utilities).
- Tap Merge on each pair, or tap Select › Select All › Merge to do them all at once. Merging keeps the best copy.
Photos does not catch near-duplicates such as bursts and retakes. Those need a quick review by eye; see delete duplicate and near-duplicate photos.
5. Unused apps (offload, do not delete)
Offloading removes the app but keeps its data. The icon stays on your Home Screen; tap it later and it reinstalls as it was.
- In Settings › General › iPhone Storage, tap an app you have not opened in months.
- Tap Offload App.
- Repeat for the biggest ones. Games and video apps often free the most.
Or let iOS handle it: Settings › App Store › Offload Unused Apps (on newer iOS, Settings › Apps › App Store).
6. Message and mail attachments
Photos and videos sent in Messages are stored on your phone, sometimes for years.
- Go to Settings › General › iPhone Storage › Messages › Review Large Attachments.
- Tap Edit, select what you do not need, and delete.
- In the Mail app, large mailboxes can grow too. Deleting old messages with big attachments, or removing and re-adding an account, clears the space.
What should I not delete?
- System Data. It is caches, logs and temporary files. You cannot delete it directly, and no app can, including ours. It usually shrinks on its own when space gets tight. Read what System Data really is.
- Apps you rely on. Deleting an app removes its data. Offload instead if you are unsure, and never delete an app that holds data only on your phone (some games, authenticator apps).
- "Other" or anything you cannot identify. If you do not know what it is, leave it. The real space is almost always in videos, apps and attachments.
- Photos and videos you have not saved anywhere else. Copy them to a computer or cloud storage before deleting.
Why does the storage number move so slowly?
Three reasons, all normal:
- Recently Deleted. Deleted photos and videos stay there for 30 days and still count. Empty it and the space returns.
- The bar takes time to refresh. After a big clean-up, close Settings, wait a minute, or restart the phone.
- System Data adjusts on its own. It grows and shrinks over time and does not respond to you deleting photos.
If you have cleared a lot and it still says full, read iPhone says storage is full but there is nothing on it.
Is it my iPhone or my iCloud that is full?
They are two different things, and the messages look similar.
- iPhone Storage is the space inside the phone. Check it at Settings › General › iPhone Storage.
- iCloud Storage is Apple's online space for backups and iCloud Photos. Check it at Settings › [your name] › iCloud.
If the message says iCloud, your phone may have plenty of room; it is your backup or photo sync that has stopped. Buying more iCloud does not add space to the phone, and clearing the phone does not add space to iCloud.
Do I need room for an iOS update?
An update needs the size shown in Settings › General › Software Update plus several GB of working room. The same order above applies, and if you cannot get there, you can update from a computer. See not enough storage to update iPhone.
Frequently asked questions
Why does it say full when I have deleted so much?
Most often because the deleted photos and videos are still in Recently Deleted, where they stay for 30 days. Empty that album and check again. If the number still does not move, restart the phone so the storage bar refreshes.
Can I make the "Storage Almost Full" message stop?
Yes, by freeing enough space that the phone is no longer near its limit. There is no switch to hide the warning, and it would not help if there were: a full phone slows down and stops taking photos.
Will deleting photos on my iPhone delete them from iCloud?
If iCloud Photos is turned on, yes. Photos syncs, so a deletion on one device happens everywhere, after 30 days in Recently Deleted. Copy anything precious to a computer or another service before you delete it.
Are iPhone cleaner apps safe to use?
Some are, some are not. Look for one that works on the phone without uploading anything, needs no account, and sends deletions to Recently Deleted so you can undo. See are iPhone cleaner apps safe?
Bottom line. A full iPhone is a normal, fixable thing. Empty Recently Deleted, deal with your biggest videos and screen recordings, merge duplicates, offload apps you never open, and clear old attachments. Leave System Data alone. Everything you remove sits in Recently Deleted for 30 days first, so nothing is lost by mistake.
