Why a full phone causes so many problems
When storage runs out, your phone doesn't just refuse new photos. Updates won't install, apps crash or won't open, messages can fail to download and the whole phone can feel sluggish. Keeping some free space gives the system room to work.
The quickest way to fix it is to go after the biggest items first, rather than deleting photos one at a time.
Step 1: See what's using your space
- iPhone: go to Settings › General › iPhone Storage. Give it a moment to load. You'll see a coloured bar, recommendations at the top and a list of apps sorted by size.
- Pixel and most Android phones: go to Settings › Storage.
- Samsung: go to Settings › Device care › Storage (called Battery and device care on some versions).
- Any Android: the Files by Google app has a Clean tab that suggests junk files, duplicates and large files to remove.
On an iPhone, start with the recommendations at the top of the storage screen. They're often the quickest wins.
Step 2: The quick wins
- Clear big message attachments. Years of photos and videos in group chats add up. On iPhone, tap Messages in the iPhone Storage list to review large attachments, photos and videos and delete them in bulk. In Samsung Messages or Google Messages, delete old conversations that are heavy on media.
- Stop keeping messages forever. On iPhone, Settings › Messages › Keep Messages can be set to 1 Year or 30 Days. Be careful: this deletes older messages and their attachments, so save anything important first.
- Offload or remove apps you don't use. On iPhone, tap an app in iPhone Storage and choose Offload App. It removes the app but keeps its documents and data, so you can reinstall later and pick up where you left off. Newer Android versions offer a similar Archive option on many phones. Otherwise, uninstall apps you haven't opened in months.
- Trim WhatsApp. In WhatsApp, open Settings › Storage and data › Manage storage. You can review large files and media that's been forwarded many times, and clean up chat by chat. Then turn off automatic media downloads, and on iPhone switch off Save to Photos so every shared image doesn't land in your camera roll twice.
- Remove downloads. Downloaded music, podcasts, offline maps and shows from streaming apps can take up a lot of space. Delete what you've already played.
- Clear your browser data. Use your browser's settings to clear history and website data. It frees up some space and can make the browser feel quicker.
Step 3: Move photos and videos to the cloud
Photos and videos are usually the biggest category. Cloud storage lets you keep them without keeping full-size copies on the phone.
- iPhone: turn on iCloud Photos and choose Optimize iPhone Storage in your iCloud photo settings. Full-size originals stay in iCloud and smaller versions stay on the phone.
- Google Photos: once your backup is complete, use the Free up space option in Google Photos to remove copies that are already safely backed up.
Check that you have enough cloud storage before you rely on it, and make sure your backup has actually finished before deleting anything from the phone.
Step 4: Empty the trash
Deleted photos don't free space straight away. On iPhone, they move to the Recently Deleted album in Photos and stay there for 30 days. Google Photos and Samsung Gallery have their own trash or recycle bin. Empty these once you're sure you don't need anything in them.
Keep it from filling up again
- Turn off auto-download for media in WhatsApp and other chat apps.
- Record video at a lower resolution for everyday clips, and save 4K for moments that matter.
- On iPhone, keep Settings › Camera › Formats on High Efficiency, which saves photos and videos as smaller files.
- Check your storage screen every couple of months.
When it's not really a storage problem
Sometimes the storage screen shows a huge "System Data" or "Other" category that won't shrink, or the phone still says it's full after you've cleared plenty. A restart often helps the system recalculate. If the phone is stuck restarting or won't get past the logo because storage filled up completely, stop trying random fixes, especially if your photos aren't backed up.

Frequently asked questions
What takes up the most storage on a phone?
Usually photos and videos, followed by message attachments, chat apps like WhatsApp, large games and downloaded music or shows. Your phone's storage screen in Settings shows exactly which apps and categories are using the most space.
Does offloading an app delete my data?
No. On iPhone, Offload App removes the app itself but keeps its documents and data on the phone. When you reinstall it from the App Store, your data comes back and you can carry on where you left off.
Why is my phone storage still full after deleting photos?
Deleted photos usually go to a Recently Deleted album or trash folder first. On iPhone they stay for 30 days. Empty that folder to free the space, then restart the phone so storage figures update.
