How to Free Up Phone Storage on iPhone and Android (Safely)

To free up space on your phone, first check what's using it: go to Settings > General > iPhone Storage on an iPhone or Settings > Storage on Android. Then remove the biggest items, which are usually unused apps, photos and videos, downloaded media and cached files.

The steps below go from quick wins to deeper cleanup. Back up anything important before you delete it.

Quick answer

• Check storage: iPhone: Settings > General > iPhone Storage. Android: Settings > Storage.
• Remove unused apps: Offload them on iPhone (keeps your data) or uninstall them on Android.
• Move photos to the cloud: Use iCloud Photos with Optimize iPhone Storage, or Google Photos backup on Android.
• Empty "Recently Deleted": Deleted photos still use space for up to 30 days.
• Delete downloads: Remove offline videos, music, podcasts and old files.
• Clear junk and cache: Use Files by Google on Android, or clear a single app's cache.

Step 1: Back Up Before You Delete

Deleting photos, messages or app data can be permanent. Before a big cleanup, make sure your phone is backed up so you don't lose memories or important files. Our guide on how to back up your phone covers both iPhone and Android.

Step 2: See What's Using Your Storage

On iPhone

1. Open Settings and tap General.
2. Tap iPhone Storage.
3. Wait a moment while the list loads. You'll see recommendations and a breakdown of how much space each app uses.
4. Tap Show All under recommendations to see every suggestion.

On Android

1. Open Settings and tap Storage.
2. Tap a category, such as Apps, Images or Videos, to see what's inside.

Menu names can vary slightly by phone maker and software version. If you can't find Storage, search for it in Settings.

Step 3: Remove or Offload Apps You Don't Use

Apps and their data are often the biggest space users.

On iPhone: Offload or delete

1. In Settings > General > iPhone Storage, tap an app.
2. Choose one of these: - Offload App removes the app but keeps its documents and data. If you reinstall it later, your data comes back. - Delete App removes the app and its related data.

Offloading is a good choice for apps you use rarely but don't want to set up again.

On Android: Uninstall

1. Open Settings > Apps and tap an app you don't use.
2. Tap Uninstall. You can reinstall it from the Play Store later.

Step 4: Manage Photos and Videos

Photos and especially videos fill phones quickly.

On iPhone

1. Turn on iCloud Photos: go to Settings, tap your name, tap iCloud, then Photos, and turn on syncing for this iPhone.
2. Make sure Optimize iPhone Storage is on. Your full-size photos stay in iCloud, and smaller versions stay on your phone when space is low.
3. You need enough iCloud storage for your library. Every account gets 5 GB free, and you can pay for more.
4. Delete duplicates and unwanted shots in the Photos app.
5. Empty the Recently Deleted album. Open Photos, tap Collections, and find Recently Deleted under Utilities. Deleted items stay there for 30 days unless you remove them.

Warning: With iCloud Photos on, deleting a photo on your iPhone also deletes it from your other devices signed in to the same Apple Account.

On Android

1. Back up your photos with Google Photos.
2. Once they're backed up, delete the copies stored on your phone to free space.
3. Or turn on Smart Storage in your phone's storage settings, if available, to clear backed-up photos and videos automatically when storage is nearly full.

Step 5: Clear Downloads, Cache and Junk Files

Delete downloaded media

Offline movies, playlists and podcast episodes can take up gigabytes. Open each streaming or music app, find its Downloads section, and remove what you've already watched or heard. Also check your Downloads folder for old PDFs, installers and attachments.

Clear an app's cache on Android

1. Go to Settings > Apps and tap the app.
2. Tap Storage & cache (the name may vary).
3. Tap Clear cache. This deletes temporary data. The app may open more slowly the next time.

Avoid Clear storage unless you're sure. It permanently deletes all of the app's data, including logins and settings.

Use Files by Google to clear junk

1. Open Files by Google.
2. Tap the Menu icon and choose Clean.
3. On the Junk files card, tap the clean button, then tap Clear to confirm.

Junk files cleared this way are deleted permanently.

On iPhone

On iPhone, the simplest approach is to check large apps in iPhone Storage and offload or delete the ones you don't need. Messaging and social apps often store lots of photos and videos, which you can remove inside the app itself.

Where Storage Usually Goes

Common Mistakes to Avoid

• Deleting photos before backing them up. Always check that your backup finished first.
• Using "Clear storage" instead of "Clear cache" on Android. Clear storage wipes an app's data and logins.
• Forgetting Recently Deleted. Deleted photos and videos keep using space until that folder is emptied.
• Installing "cleaner" or "booster" apps. Many show fake warnings or ads and add little. Built-in tools and Files by Google are enough. Learn how to spot online scams disguised as cleanup tools.
• Deleting what you can't replace. If you remove something by mistake, see how to recover deleted files as soon as possible.

Frequently Asked Questions

Why is my phone storage full when I don't have many apps?

Photos, videos, messages with attachments and downloaded media usually take more space than apps. Check the storage screen to see which category is largest, then start there.

What's the difference between offloading and deleting an app on iPhone?

Offloading removes the app but keeps its documents and data, so everything returns when you reinstall it. Deleting removes the app and its data. Offloading is safer if you might need the app again.

Is it safe to clear cache on Android?

Yes. Clearing cache only removes temporary files, and the app rebuilds what it needs. It may load a little more slowly at first. Clearing storage is different and erases the app's data.

Will deleting photos from my phone delete them from the cloud?

It depends. With iCloud Photos on, deleting on your iPhone deletes everywhere. With Google Photos, removing only the on-device copies of backed-up photos keeps the cloud copy. Read the on-screen message carefully before confirming.

How much free space should I keep on my phone?

There's no exact official number. Leaving some space free gives your phone room for updates, new photos and temporary files. If you get low-storage warnings, act on them.
