The “Storage almost full” warning always arrives at the worst moment. Before deleting your holiday photos, know that in most cases the wasted gigabytes are somewhere else. Follow these steps in order: the first ones free the most space with the least effort.
1. See where the storage goes
On iPhone: Settings > General > iPhone Storage. On Android: Settings > Storage. The screen shows how much is taken by photos, apps, videos and “other” or “system data”. That is the map to start from.
2. Clear the WhatsApp and Telegram cache
Messaging apps are almost always the first culprit: they save every photo, video and meme received in group chats. In WhatsApp go to Settings > Storage and data > Manage storage: you can delete the largest files and the ones forwarded many times, without touching the chats. In Telegram: Settings > Data and storage > Storage usage > Clear cache.
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. On iPhone you can also turn on “Offload unused apps”, which 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 100 GB or 200 GB plans cost around 2 or 3 euros a month, often less than you’d think.
5. Check downloads and recorded videos
The Downloads folder is full of forgotten PDFs, tickets and attachments. And 4K videos weigh about 400 MB per minute: if you have many, move them to a computer or the cloud and consider recording in 1080p, which is more than enough for 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 often shrinks with a simple restart or, in stubborn cases, a backup and restore. On Android, some manufacturers include a cleaning tool under Storage that removes duplicate and temporary files with one tap.
