iOS keeps saying my storage is full even after I deleted lots of photos. Why?

Deleted photos go to the Recently Deleted album first and stay there for 30 days — they still count against your storage until you permanently delete them. Open the Photos app, tap Albums, scroll to Recently Deleted, and tap Delete All. Also restart your iPhone after clearing space, as iOS sometimes takes a few minutes to update the storage reading.

Will turning on iCloud Photos delete photos from my phone?

No. Turning on iCloud Photos uploads your photos to iCloud and keeps them there. If you choose 'Optimise iPhone Storage,' iOS may replace full-size copies on your phone with smaller previews to save space — but the originals remain safely in iCloud and re-download when you open them. Nothing is deleted.

iPhone Storage Full — Practical Ways to Free Up Space

When your iPhone runs out of storage, things break quietly — photos won't save, apps crash, and iOS itself can behave strangely. The good news is that a few targeted steps usually recover several gigabytes quickly.

See What's Eating Your Storage

Before deleting anything, find out what's taking up space. Go to Settings → General → iPhone Storage. iOS will show a colour-coded bar and a list of apps sorted by size. Scroll down — iOS also gives personalised recommendations at the top of that screen.

Quick Wins

Offload unused apps. Tap any app in the storage list and choose Offload App. This removes the app but keeps its data, so you can reinstall it later without losing anything. You can also enable this automatically under Settings → App Store → Offload Unused Apps.
Clear streaming app caches. Spotify, Netflix, and Apple Music can cache gigabytes. Inside each app, go to its settings and look for a Clear Downloads or Clear Cache option.
Delete old text message attachments. Go to Settings → General → iPhone Storage → Messages to see photos and videos sent in texts. You can delete large attachments without deleting the conversations.

Tackle Photos — Usually the Biggest Culprit

Enable iCloud Photos. Go to Settings → [your name] → iCloud → Photos and turn on iCloud Photos, then choose Optimise iPhone Storage. iOS keeps small previews on your phone and full-resolution originals in iCloud. You need an iCloud plan with enough space.
Delete duplicates and screenshots. The Photos app has a Duplicates album (under Utilities) that merges identical shots automatically. Screenshots pile up quickly — delete ones you no longer need.
Recently Deleted photos. Deleted photos stay in your Recently Deleted album for 30 days. Go to Albums → Recently Deleted and tap Delete All to free that space immediately.

Clear Safari's Cache

Go to Settings → Safari → Clear History and Website Data. This removes cached web pages, cookies, and browsing history. It can free hundreds of megabytes on phones that browse a lot.

Check for Large Downloaded Videos

Go to Settings → General → iPhone Storage and look for the TV or Apple TV app. Downloaded films are often several gigabytes each. Delete any you've already watched.

If your storage is genuinely full and you need more headroom long term, upgrading your iCloud plan (from £0.99/month in the UK or $0.99/month in the US for 50 GB) is often the most painless route. Ask us if you'd like help picking the right plan.
