If your phone still sends “Storage almost full” alerts after deleting photos, videos, files, or apps, you might wonder, “Why is my phone storage full after deleting everything?” But don’t worry, the issue is likely cache files, system data, recently deleted folders, or offline downloads.

At Asurion, we help millions of people get the most out of their tech, whether you want to clear app cache on your phone or need help deciding what to delete when you run out of space. Here’s how to free up space when your phone says storage is full after deleting everything.

Empty recently deleted photos, messages, and files

Modern smartphones don’t remove deleted items immediately. On iPhone®, files move to the Recently Deleted folder, while many Android™ devices store them in the Trash folder for 30 days. Until the files are permanently deleted, they continue to occupy storage space.

To permanently delete on an iPhone

To permanently delete recently deleted photos on iPhone, take these steps:

1. Open Photos > Collections > Recently Deleted.
2. Select View Album and use Face ID or Touch ID when prompted.
3. Tap Select > More (…) > Delete All.
4. Select Delete from All Devices or Delete Photos I Added.

For non-image files, follow these steps to solve the issue of iPhone storage being full after deleting everything:

1. Open the Files app > Browse > Recently Deleted.
2. Tap More (…).
3. Choose Select > Delete All.

To permanently delete recently deleted messages and attachments on iPhone, take these steps:

1. Open the Messages app.
2. Select the Filter button > Recently Deleted.
3. Tap Delete All and confirm the deletion.

How to empty the Trash folder on Android

If your Android system storage is full after deleting everything, the steps to free up phone storage depend on your device. On Samsung® and most Android devices, proceed as follows:

1. Find the Gallery app > Menu ≡ > Trash.
2. Tap All.
3. Select Menu (⋮) > Delete all > Delete.

To clear recently deleted non-photo or non-video files, take the following steps:

1. Go to My Files or Files by Google.
2. Select Menu ≡ > Trash.
3. Tap Delete all.

Clear app cache and temporary data

Your browser, social media apps, navigation apps, or streaming services store temporary files called cache to load faster. Over months, this hidden data can grow into several gigabytes.

To clear the cache on Android:

1. Go to Settings > Apps.
2. Select the app you want to clear the cache for.
3. Tap Storage > Clear cache.

To clear the cache on an iPhone:

iPhone doesn’t let you clear individual app caches in Settings, but you can offload apps to remove them while keeping their files on your device.

Delete offline downloads and large attachments

If you download offline content from Netflix, Spotify, YouTube Premium, or podcasts, files can accumulate and take up significant space.

To clear offline downloads (Netflix, Spotify, YouTube)

• Netflix: Open the app > Tap your Profile icon > App Settings > Delete All Downloads.
• Spotify: Open the app > Tap your Profile icon > Settings and Privacy > Scroll down to Storage > Tap Remove all downloads.
• YouTube Premium: Open the app > Tap your Profile icon > Settings > Background & downloads > Tap Delete downloads.

Also, check and delete large message attachments.

On iPhone:

1. Go to Settings > General > iPhone Storage.
2. Then scroll to Messages > Review Large Attachments.
3. Select Edit to select attachments to delete.

On Google Messages (Pixel, Samsung, Motorola, etc.):

1. Open the Messages app.
2. Tap your profile picture or the three-dot menu.
3. Go to Messages settings > Device storage (or Manage storage on some phones).
4. Look for large files, videos, images, attachments.
5. Select the items you want to remove, then tap Delete.

On Samsung Galaxy phones:

1. Open Settings.
2. Tap Battery and device care > Storage.
3. Tap Duplicate files, Large files, or Unused apps.

Reduce system data and other storage

In your storage breakdown, you’ll see System Data on iPhone or System/Other storage on Android.

While you can’t clear System Data entirely, a few steps help reduce it.

• Restart your device to clear temporary files
• Clear the browser history to remove the stored website data
• Update your operating system to optimize how the system manages storage
