My iPhone storage is full. What can I safely delete?

The simple answer

Start by checking what is actually using the space.

Go to:

  1. Settings
  2. General
  3. iPhone Storage

Your iPhone will show which apps, photos, videos and other items are taking up the most room. It may also suggest ways to free space.

The safest place to start is usually:

  1. Unused apps
  2. Downloaded media
  3. Large files you recognise

Be much more careful with photos, videos and personal documents.

Before you delete anything

Don’t start with your photos

For many people, photos and videos are the things they would be most upset to lose.

If you use iCloud Photos, deleting a photo on your iPhone can also delete it from other Apple devices using the same iCloud Photos library.

Deleted photos normally remain in Recently Deleted for 30 days before permanent deletion.

If you aren’t sure whether something important is safely stored somewhere else, don’t delete it just to make space.

Step 1 — See what is using your storage

Open:

  1. Settings
  2. General
  3. iPhone Storage

At the top you will see how much storage is being used.

Below that, your apps are listed with the amount of space each one uses.

Your iPhone may also show storage recommendations.

What can I safely remove first?

1. Apps you don’t use anymore

Look down the app list.

If you see an app you haven’t used for months, it may be a good candidate.

But there are two different choices.

Offload App

Removes the app itself to free space but keeps its documents and data.

If you reinstall the app later, its saved data may be available again where the app supports it.

Delete App

Removes the app and its related data.

Not sure? Offload is the safer first choice.

2. Downloaded films, programmes, music and podcasts

Downloaded entertainment can quietly use a lot of space.

Examples:

  • Netflix downloads
  • YouTube downloads
  • Spotify or Apple Music downloads
  • podcasts
  • downloaded TV programmes or films

If the content can easily be downloaded again later, removing the downloaded copy is generally much safer than deleting personal photos or documents.

Remove the download — not necessarily the account, playlist or app.

3. Large files you recognise

Check apps such as Files, or apps where you regularly receive large documents and videos.

Examples:

  • old PDFs
  • downloaded documents
  • videos someone sent you
  • files you no longer need

Only delete files you recognise.

Don’t start deleting folders because their names look unfamiliar.

What about photos and videos?

Photos and especially videos can use a large amount of phone storage.

But they should not be the first thing you delete if they are important to you.

If you use iCloud Photos, Apple offers Optimize iPhone Storage.

Full-resolution originals can be stored in iCloud while smaller space-saving versions remain on the iPhone when space is needed.

Go to:

  1. Settings
  2. Your name
  3. iCloud
  4. Photos
  5. Optimize iPhone Storage

Important

Optimize iPhone Storage is different from deleting photographs.

With iCloud Photos turned on, deleting a photograph can also delete it from other devices connected to the same photo library.

What should I NOT delete casually?

Photos and videos

Especially family photos or anything you haven’t confirmed is safely stored elsewhere.

Files and documents

Don’t delete unfamiliar documents simply because they are large.

Apps containing important local information

Some apps may store information on the phone itself.

Anything you don’t recognise

A mysterious system-looking item is not an invitation to delete it.

If you don’t know what something is, leave it alone until you understand it.

Should I use “Offload Unused Apps”?

It can help.

Your iPhone may offer Offload Unused Apps as a storage recommendation.

Offloading frees the space used by the app itself while keeping its documents and data.

For someone who wants a simple first step, this is generally less destructive than manually deleting a collection of apps.

But still look at what your phone is suggesting before enabling anything automatically.

Why does my iPhone fill up again?

Storage isn’t only apps.

Over time your phone can accumulate:

  • photographs
  • videos
  • downloaded media
  • messages and attachments
  • documents
  • app data
  • temporary files

iOS also manages some temporary and re-downloadable content itself when storage becomes tight.

Deleting one small app may not solve a problem caused by a large collection of videos.

That is why iPhone Storage should always be the first screen you check.

How much free space should I keep?

You don’t need to constantly manage your phone around an exact number.

But a phone with almost no free storage can have trouble with things such as software updates and normal operation.

Apple advises keeping at least 1 GB of free space to help avoid slowdowns.

The one thing to remember

Check first. Delete second.

Unused app?
Offload it first if you’re unsure.
Downloaded film or music?
Usually easy to download again.
Photo, video or personal document?
Make sure you know where another copy exists before deleting it.
