How to clear storage on an iPhone without losing your photos

"iPhone Storage Full." Once that message appears, the camera won’t take pictures, updates won’t install, and the phone can slow down. The tempting fix is to start deleting photos. Please don’t, at least not yet. There are usually easier ways to free up a lot of space.

First, see what’s using the space

1. Open Settings.
2. Tap General, then iPhone Storage.
3. Wait a moment for the colored bar at the top to load.

You’ll see how much space is used, and a list of apps from biggest to smallest. Below the bar, your iPhone often shows Recommendations, like turning on iCloud Photos or reviewing large videos. These suggestions are usually good ones.

For most people, the biggest items are Photos, Messages and a few large apps.

Step 1: Store photos in iCloud, not just on the phone

If you have years of photos and videos, this is usually the biggest win. It keeps full-size originals safely in iCloud and smaller versions on your phone. You can still see every photo, and tapping one downloads the full version.

1. Open Settings and tap your name at the top.
2. Tap iCloud, then Photos.
3. Turn on Sync this iPhone (on older versions, iCloud Photos).
4. Choose Optimize iPhone Storage.

The catch: Apple’s free iCloud plan is only 5 GB, which fills up quickly. The paid iCloud+ plans start at a low monthly price and are worth it for most families with a lot of photos. If you’re on a Family Sharing plan, storage can be shared with family.

If you’d rather use Google, the Google Photos app can back up your photos too. Once backed up, Google Photos has a Free up space option that removes the copies stored on the phone.

Step 2: Empty "Recently Deleted"

When you delete photos, they’re kept for 30 days in case you change your mind, and they still take up space.

1. Open the Photos app.
2. Scroll down to Utilities (or Albums on older versions) and tap Recently Deleted.
3. Unlock with Face ID or your passcode, tap Select, then Delete All.

Only do this if you’re sure you don’t need anything in there.

Step 3: Trim old messages and attachments

Years of texts with photos and videos can take up gigabytes.

1. Go to Settings > General > iPhone Storage, and tap Messages.
2. Tap Review Large Attachments and delete videos and photos you don’t need. Saved photos in your library aren’t affected.
3. Optional: in Settings > Apps > Messages, tap Keep Messages and choose 1 Year. This deletes older conversations automatically, so only do it if you’re comfortable with that.

Tip: turning on Messages in iCloud (Settings, your name, iCloud) keeps conversations backed up and syncs them across devices.

Step 4: Offload apps you don’t use

Offloading removes an app but keeps its data, so if you reinstall it later, everything is still there.

1. In iPhone Storage, tap an app you rarely use.
2. Tap Offload App.

Or let the phone do it for you: in Settings > Apps > App Store, turn on Offload Unused Apps.

If an app has a large "Documents & Data" number, like a podcast app with downloaded episodes or a streaming app with downloaded shows, open that app and delete downloads from inside it.

Step 5: Clear downloaded videos and music

Downloaded movies from Netflix, songs from Apple Music, or podcasts can take a lot of space. Open each app, find the Downloads section, and remove what you’ve already watched or listened to.

What about "System Data"?

Sometimes a gray section called System Data (or "Other") is huge. This is temporary files and caches. It often shrinks on its own. Restarting the phone can help, and installing the latest iOS update usually does too. If it stays very large, that’s when a backup and restore can make sense, but that’s worth doing with help.

On an Android phone

The steps are similar:

1. Use Files by Google. Open the Files app and tap Clean. It suggests junk files, duplicates, old downloads and large files to remove.
2. Back up photos with Google Photos, then tap your profile picture and choose Free up space to remove copies already backed up.
3. Samsung phones: go to Settings > Device care > Storage for suggestions, and empty the Recycle bin in the Gallery app.
4. Clear an app’s cache: Settings > Apps > choose the app > Storage > Clear cache. Avoid "Clear data" unless you know what it does, since it can sign you out and erase the app’s saved information.

When it’s time for a bigger phone

If you’ve done all of this and the phone is still full within weeks, the phone may just have too little storage for how you use it. Older 32 GB and 64 GB phones fill up fast. When choosing a new one, 128 GB or more is a comfortable size for most people. Our guide to the best phone for elderly parents covers what else to look for.

When to get help

Moving years of photos to iCloud or Google Photos safely, especially when there are precious family pictures involved, is something many people prefer not to do alone. We can help you check that everything is backed up before anything is removed, and set up sharing so the family can see the photos too.
