How to Free Up Storage on Your Phone Without Losing Your Photos
Seven ways to reclaim space on an iPhone or Android phone, from clearing app caches to backing up photos and removing downloads you no longer need.
“Storage almost full” is one of the most irritating messages a phone can show. The good news is that you can usually get several gigabytes back without deleting anything you care about.
1. See what is using the space
- iPhone: open Settings, then General, then iPhone Storage.
- Android: open Settings and look for Storage (the name varies by manufacturer).
These screens show which apps and file types take the most space, so you can tackle the biggest ones first.
2. Back up photos and videos, then free up space
Photos and videos are usually the largest category. Back them up to the cloud first (for example with iCloud Photos or Google Photos), confirm they appear on another device or on the web, and then use the built-in option to remove the local copies:
- On iPhone, turn on Optimise iPhone Storage in Photos settings.
- In Google Photos, use the Free up space option.
Avoid simply deleting photos from the gallery if sync is on, because that can delete the cloud copy too.
3. Empty the recently deleted folders
Deleted photos often stay in a “Recently Deleted” or trash folder for a month or more before they are erased for good. Emptying it frees the space straight away. Only do this once you are sure you do not need the items.
4. Offload or remove apps you do not use
Go through your app list and remove what you have not opened in months. On iPhone, Offload Unused Apps removes the app but keeps its documents and data, so reinstalling restores everything.
5. Clear app caches
Browsers, social media and streaming apps can store gigabytes of temporary files. On Android, you can clear an app’s cache from Settings, then Apps, then the app’s Storage page. On iPhone, some apps offer a clear-cache option in their own settings, and the Offload option above achieves a similar result.
6. Delete downloads and offline media
Check for downloaded podcasts, offline playlists, offline maps and movies saved for travel. Remove the ones you have already watched or listened to.
7. Tidy messaging apps
Messaging apps save every photo and video you receive. In iMessage, you can review large attachments from the iPhone Storage screen. In WhatsApp and similar apps, look for a Manage storage option to find and delete large files.
Quick wins checklist
| Action | Typical saving |
|---|---|
| Back up photos, remove local copies | Often the largest |
| Empty Recently Deleted | Varies |
| Remove unused apps | Moderate |
| Clear browser and app caches | Moderate |
| Delete old downloads | Varies |
| Clean up messaging attachments | Can be large |
Keep it from filling up again
Turn on automatic cloud backup, set messaging apps to delete or not save media automatically, and review storage every few months.
Frequently asked questions
Is it safe to clear an app's cache?
Yes. A cache holds temporary files that the app can rebuild. Clearing it will not delete your account or saved data, though the app may load more slowly the first time you reopen it.
Will deleting photos from my phone delete them from the cloud?
It can. With cloud sync, deleting a photo in one place may delete it everywhere. Use the app's own 'free up space' or 'optimise storage' option instead, which removes only the local copy once it is safely backed up.
How much free space should I leave?
As a rule of thumb, keeping 10 to 15% of your storage free helps your phone run smoothly and leaves room for updates.
