The “Storage almost full” warning always arrives at the worst moment. Before you delete your holiday photos, though, know that in most cases the wasted gigabytes are somewhere else. Follow these steps in the order you find them, because the first ones free the most space with the least effort.
Storage: the space where the phone keeps photos, apps and files. On Android the menu may call it "Storage" or "Memory". Cache: files apps keep aside to run faster. Clearing it does not delete your own things. GB (gigabyte): the unit space is measured in; a thousand MB make one GB.
1. See where the storage goes
On iPhone: Settings > General > iPhone Storage. On Android you go through Settings > Storage (or Memory). The screen shows how much is taken by photos, apps, videos and that vague entry called “other” or “system data”.
Start here. Without that map you end up deleting the things you are most attached to.
2. Clear the WhatsApp and Telegram cache
Messaging apps are almost always the first culprit, because they save every photo, video and meme received in group chats. In WhatsApp go to Settings > Storage and data > Manage storage, where you can delete the largest files and the ones forwarded many times without touching the chats. In Telegram the path is Settings > Data and storage > Storage usage > Clear cache.
This is generally where you get back the easiest gigabytes on the whole list.
3. Remove the apps you don’t use
Both iOS and Android show when you last used each app. A 2 GB game last opened a year ago can go, and you can reinstall it in two minutes if you fancy it again. On iPhone you can also turn on “Offload unused apps”, under Settings > App Store: it removes the app but keeps its data for when you reinstall it.
4. Move photos to the cloud, not to the bin
Google Photos and iCloud Photos offer an “Optimise storage” option: the originals stay in the cloud and the phone keeps only a lightweight version, downloaded when you open it. Google’s free plan is 15 GB, Apple’s 5 GB; the small paid tiers sit at around one or two euros a month, but prices and tiers change over time, so check the official Google One and iCloud+ pages before choosing.
5. Check downloads and recorded videos
The Downloads folder is full of forgotten PDFs, tickets and attachments. And 4K video weighs around 200 MB per minute, which doubles if you record at 60 frames per second. If you have a lot of them, move them to a computer or the cloud, and at that point I would switch to recording in 1080p, which is more than enough for watching things on a phone.
6. Empty the Photos bin
Deleted photos stay in the bin for 30 days and keep taking up space. Under Photos > Albums > Recently Deleted you can empty it right away.
If that’s not enough
“System data” on iPhone is largely cache that iOS clears by itself when the space is genuinely needed. Wait a couple of days before worrying, and only in stubborn cases go for a backup and restore. On Android, some manufacturers include a cleaning tool under Storage that removes duplicate and temporary files with one tap.
