When your phone says storage is full, you don’t have to delete your photos to get space back. Most of the room is usually taken by a few big things: videos, app data, old message attachments and cached files. Back up first, then clear the biggest items in the right order, and you can often recover several gigabytes without losing anything you care about.

The short version

  • Back up your photos and videos before you delete anything.
  • Check your phone’s storage screen to see what’s actually using the space.
  • Videos, message attachments and offline downloads are usually the biggest culprits.
  • Offloading or archiving unused apps frees space but keeps your data.
  • Empty the “Recently Deleted” or Trash folder, or the space won’t come back right away.

A phone with almost no free space does more than refuse new photos. Software updates can fail to install, apps may crash or lose their place, and the system has less room for the temporary files it needs to run smoothly. If your phone has also started to feel sluggish, low storage is one of the common causes we cover in why your phone is slow and how to fix it.

A good target is to keep at least a few gigabytes free at all times, and more before a major system update.

Step 1: Back up before you delete anything

The single most important step is making sure your photos and videos exist somewhere other than your phone. Once they’re safely backed up, you can remove the full-size copies from the device without worrying.

  • iPhone: iCloud Photos keeps your library in iCloud. You can also copy photos to a computer with a cable.
  • Android: Google Photos can back up your library to your Google Account. Samsung phones also offer their own backup options, and you can copy files to a computer over USB.

Check that the backup has actually finished before moving on. Open your photo app and look for a status message showing that everything is backed up or synced. Our guide on how to back up your phone walks through the full process, including messages and app data.

Keep in mind that free cloud storage tiers are limited. If your library is large, you may need a paid plan or a second copy on a computer or external drive.

Step 2: Find out what’s using the space

Don’t guess. Both platforms show a breakdown of your storage:

  • iPhone: go to Settings > General > iPhone Storage. You’ll see a coloured bar by category, recommendations, and a list of apps sorted by size.
  • Android: open Settings and search for “Storage”. On Samsung phones it usually sits under the device care or battery and device care section. You’ll see categories such as images, videos, apps, and documents.

The list usually makes the problem obvious. Often it’s one or two apps with huge amounts of saved data, or a camera roll full of long videos.

Step 3: Make your photo library take less room

Once your library is backed up, you can keep every photo viewable while storing far less on the phone itself.

On iPhone

With iCloud Photos turned on, choose Optimize iPhone Storage in the Photos section of Settings. Your phone keeps smaller versions on the device and downloads the full-resolution originals from iCloud when you open them. This needs enough iCloud space for your whole library.

On Android

Google Photos has a Free up space option that removes device copies of photos and videos that have already been backed up. They stay in your Google Photos library and remain viewable when you’re online. Read the confirmation screen carefully so you know exactly what will be removed from the device.

Clean up the obvious waste

  • Delete duplicate shots, blurry bursts and accidental screen recordings.
  • Review your longest videos first. A few minutes of 4K video can take up as much room as hundreds of photos.
  • Consider a lower video resolution in the camera settings for everyday clips.

Empty the deleted items folder

This catches a lot of people out. When you delete photos, they usually go to a holding area first, not straight into the bin:

  • iPhone: the Photos app keeps deleted items in the Recently Deleted album for about 30 days.
  • Google Photos: deleted items go to the Trash (called Bin in some regions) and are kept for a limited time before being removed.

Until you empty these folders, the space isn’t freed. Only empty them once you’re sure you’ve kept everything you want, because anything removed from there is gone for good.

Step 4: Deal with apps and their data

Apps themselves are often smaller than the data they store. Look at the size of each app on your storage screen.

  • Offload or archive apps you rarely use. On iPhone, Offload App removes the app but keeps its documents and data, so you can reinstall it and pick up where you left off. Newer versions of Android and the Google Play Store offer a similar archive feature for apps you haven’t used in a while.
  • Remove offline downloads. Streaming, music, podcast and map apps can quietly store gigabytes of downloaded episodes, playlists and maps. Delete the ones you’ve already watched or listened to from inside each app.
  • Clear cache on Android. In Settings > Apps, choose an app, then Storage, and tap Clear cache. This is safe. Avoid Clear storage or Clear data unless you understand it will reset the app and may remove saved content.
  • Uninstall apps you truly don’t use. Games in particular can be very large.

Step 5: Trim messages and chat attachments

Years of photos, videos and voice notes in group chats add up fast.

  • iPhone Messages: in Settings > Messages, the Keep Messages option can be set to 30 days or 1 year instead of Forever. Be careful: changing this deletes older messages and attachments. You can also review large attachments from the Messages entry in iPhone Storage.
  • WhatsApp: go to Settings > Storage and data > Manage storage to see and delete the largest files and busiest chats. You can also turn off automatic media downloads so every forwarded video doesn’t land on your phone.
  • Other chat apps: most have a storage or data section in their settings. Check for a similar option.

Save any photos or videos you want to keep to your photo library (and let them back up) before clearing chat media.

Other quick wins

  • Downloads folder: on Android, the Files app often holds old PDFs, installers and attachments you forgot about. Google’s Files app has a cleaning feature that suggests junk files, duplicates and large files to remove.
  • Browser data: clearing browser history and website data can free a little space, though it will sign you out of some sites.
  • Memory card: some Android phones accept a microSD card for photos, videos and music. iPhones don’t have a card slot, so cloud storage or a computer backup is the way to go.
  • Restart: after a big clean-up, restart your phone so the system can finish tidying temporary files.

When storage problems point to something else

If your phone still reports full storage after you’ve deleted a lot, the “System Data” or “Other” category is unusually large, or the phone keeps freezing or restarting, there may be a software problem rather than too many files. In that case, a careful backup followed by a software fix can help. Don’t reset your phone before you’re sure everything important is backed up.
