Key takeaways
- Google distinguishes storage, where you keep data such as photos and music, from memory, where apps and the system run.
- Google's Android help says Settings, Storage, Free up space lets you pick from photos, videos and apps you have not used recently; some steps need Android 14 or later.
- If photos are backed up with Google Photos, the copies on the phone can be deleted while the backups stay in the cloud.
- Archiving removes an unused app but keeps its personal data and icon; you can download it again as long as it is on Google Play.
- Delete downloaded content from the app that downloaded it, and compress image-heavy PDFs before keeping or sending them.
"Storage almost full" arrives at the worst moments: mid-photo, mid-download, mid-update. Freeing space is quicker when you know what is filling the phone and which tools Android already gives you. This guide follows Google's own Android help, then adds the space hogs it does not mention, such as large PDFs.
Storage is not memory
Google's help starts with a useful distinction. Storage is where you keep data, like music and photos. Memory is where you run programs, like apps and the Android system. A "storage full" warning means you are out of room to save things; it does not mean apps lack memory to run. Closing apps, which Google says you do not usually need to do, will not free storage.
Step 1: use Free up space
Google's Android help describes a built-in tool:
- Open Settings.
- Tap Storage, then Free up space.
- Scroll to a category, such as photos, videos or apps you have not used recently, tap Select files (or Browse if the category is not listed) and select what to delete.
- Tap Move files to Trash.
On the same Free up space screen, Google says Menu, then Settings, then Smart Storage clears backed-up photos and videos automatically when storage is almost full. Google notes some of these steps only work on Android 14 and up, and its help says settings can vary by phone, so your menus may be named or arranged differently.
Step 2: deal with photos and videos
Google's help points out that if you back up with Google Photos, you can delete the copies on your phone and still find the backed-up versions in the app when connected to the internet. Check that the backup has finished before deleting. Alternatively, Google says you can move files to a computer with a USB cable and then delete them from the phone.
Step 3: remove downloads and offline media
Downloads can include attachments, installers, offline videos, music and maps. Google's help says to delete downloaded content from the app you used to download it, for example removing a downloaded video in Google TV or a downloaded album in YouTube Music, and to delete downloaded files you no longer need.
Step 4: uninstall or archive unused apps
Apps you never open still take space. Google's help gives two options:
- Uninstall apps you do not use. If you need one later, you can download it again, and you do not have to pay again for a paid app.
- Archive them. Archiving removes an app you do not use often but saves your personal data in it, and keeps its icon on your device; Google says you can download it again as long as it is still available on Google Play. Google Play can do this automatically: in the Play Store app, open your profile, then Settings, then General, and turn on Automatically archive apps.
Step 5: clear app cache, carefully
Apps keep temporary files called the cache. Google's help says clearing the cache deletes temporary data, though some apps may be slower the next time they open, while clearing storage permanently deletes all of an app's data. Clear cache first; clearing an app's cache versus its storage explains when each is appropriate.
Other files worth checking
- Scanned PDFs: a PDF made from phone photos holds an image for every page, so it can be much larger than a text PDF. Compressing it can reduce its size; how to compress a PDF explains how.
- Duplicate attachments: the same file saved from email, a chat app and a download folder.
- Video files: long recordings you have already watched or backed up elsewhere; the Free up space list includes videos, so check it there.
- Chat media: photos, videos and voice notes received in messaging apps may be saved to the phone as well as kept in the chat; check each messaging app's own storage settings to see and clear what it holds.
A worked example: finding 5 GB
Suppose, with hypothetical figures, that your phone has 2 GB free and you need 7 GB for an update and some downloads. One plan: clear 3 GB of photos and videos already backed up to Google Photos; remove 1.5 GB of downloaded videos you have watched; archive three unused games at about 0.5 GB each, which is another 1.5 GB. That is 6 GB freed, leaving 8 GB free, without deleting anything you cannot get back, provided the backups have finished and the games are still on Google Play.
Keep it from filling up again
Turn on automatic archiving and Smart Storage where your phone offers them, and review downloads from time to time. Compress large PDFs before saving them; Google's Gmail help notes that attachments also count toward your Google account storage, so smaller files help there too.
PDF All in One Tool No Limit compresses PDFs, and Video Player All Formats PRO plays the videos you keep; both are among our video and utility apps.
