Running out of space on an iPhone or iPad is one of the most common things people ask us about. It's not a sign that anything is wrong with the device — it's simply what happens after a few years of photos, videos, and messages. The good news is that most of the space is usually sitting in three or four predictable places, and clearing it doesn't mean losing your memories.
Start by seeing where the space actually went
Before deleting anything, look at what's using the room.
- Open Settings, tap General, then tap iPhone Storage (on an iPad it's iPad Storage).
- Give it a moment to work out the numbers, then look at the colored bar at the top. It shows how much of your storage is photos, apps, messages, and so on.
- Underneath the bar, Apple lists Recommendations — its own suggestions for this device. These are safe to read through before you decide anything.
- Below that is every app on the device, sorted from largest to smallest. That list is usually where the surprise is.
Nine times out of ten, the top of that list is Photos.
Photos and videos: the big one
Videos in particular are enormous, and it's easy to have years of them sitting on the device itself.
- Turn on iCloud Photos with "Optimize Storage." Open Settings, tap your name at the top, then iCloud → Photos, and choose Optimize iPhone Storage. Your full-quality photos and videos live safely in iCloud, and the device keeps smaller versions locally, downloading the full one whenever you open it. This is the single biggest space saver for most people.
- Empty the Recently Deleted album. In the Photos app, look under Albums → Recently Deleted. Anything you delete sits there for 30 days and still takes up room. Once you're sure, choose Delete All.
- Check for duplicates. Also under Albums, Photos shows a Duplicates album when it finds any, and it can merge them for you while keeping the best version.
Messages: the space nobody thinks about
Every photo, video, and voice message anyone has ever sent you is still sitting in Messages.
- Stop keeping them forever. Open Settings, then Apps → Messages (on older versions it's just Settings → Messages), find Keep Messages, and change Forever to 1 Year. Your recent conversations stay; the very old ones tidy themselves away from then on.
- Clear the big attachments. Back in Settings → General → iPhone Storage, tap Messages. You'll see Review Large Attachments, listing the biggest videos and photos people have sent you, largest first. Deleting a few of those often frees more space than deleting a dozen apps.
Apps and downloads
- Let the device offload apps it isn't using. In Settings → General → iPhone Storage, turn on Offload Unused Apps. This removes the app itself but keeps all of its documents and data, and the icon stays on your Home Screen — tap it and it downloads again with everything as you left it.
- Look for downloaded shows, films, and podcasts. Apple TV, Netflix, Audible, and the Podcasts app all quietly store downloads on the device. Opening each app's own downloads section and clearing what you've already watched or listened to can recover a lot in one go.
If it keeps filling up
If you clear space and find yourself back in the same position a few months later, the honest answer is usually that the iCloud storage plan is too small for how much you photograph. The free 5GB hasn't been enough for most people for years. Moving up a tier is inexpensive and it means the device can keep optimizing instead of running out. We're happy to look at which plan actually suits you rather than guessing.
