How to Free Up Storage Space on Your iPhone

iPhones are efficient with storage, but they’re not magic — and once you see that “iPhone Storage Almost Full” warning, everything starts getting awkward. Here’s how to systematically deal with it.

Check What’s Actually Using Your Space

Go to Settings → General → iPhone Storage. iOS gives you a colour-coded bar and a list of apps sorted by size, with a recommendation section at the top. Read those recommendations — Apple’s suggestions are generally sensible (offloading unused apps, reviewing large attachments, and so on).

The list takes a moment to fully populate — wait for it to settle before drawing conclusions.

Offload Unused Apps

iOS has a great feature called Offloading: it removes the app binary but keeps all your data, so when you reinstall it everything is exactly as you left it. You can enable automatic offloading in Settings → App Store → Offload Unused Apps, or do it manually per app in the iPhone Storage list.

This is especially useful for large games or infrequently-used apps where you want to keep your save data or settings.

Sort Out Your Photos Library

Photos is almost always the biggest consumer on any iPhone. A few things to tackle:

• Enable iCloud Photos: If you’re not already using iCloud Photos with Optimise iPhone Storage turned on, do it now. Go to Settings → [Your Name] → iCloud → Photos and enable it. iOS will keep lower-resolution versions on the device and store full-resolution originals in iCloud — you’ll barely notice the difference day-to-day.
• Delete duplicates: iOS 16 and later has a built-in Duplicates album in the Photos app. Open Photos → Albums → scroll to Utilities → Duplicates. It does the comparison for you and lets you merge or delete with one tap.
• Clear Recently Deleted: Deleted photos stay in the Recently Deleted album for 30 days. Go to Albums → Recently Deleted → Delete All to reclaim that space immediately.
• Review screenshots and videos: Screenshots accumulate fast and are rarely worth keeping long-term. Videos are large — a 4K video clip can be 500MB+. Review them in Albums → Videos and delete anything you’ve already shared or backed up.

Check Individual App Storage

In the iPhone Storage list, tap any app to see how much space the app itself takes versus its documents and data. Some standouts to check:

• Podcasts: Old episodes download and never get deleted. In the Podcasts app: go to each show → Settings → and set downloaded episodes to auto-delete after listening.
• Spotify / Apple Music: Downloaded music and podcasts add up. Go into each app’s settings to remove offline content you no longer need.
• Messages: Tap Messages in the iPhone Storage list to see audio messages, photos, and videos stored in your conversations. You can delete entire threads or attachments without deleting the messages themselves.

Clear Safari Cache

Go to Settings → Safari → Clear History and Website Data. This clears cached web content and browsing history. It won’t recover huge amounts of space, but it’s worth doing periodically — especially if Safari’s website data has grown over time.

Review iCloud Backups

If you’re backing up to iCloud, old backups from previous phones or tablets might be sitting in your storage allocation. Go to Settings → [Your Name] → iCloud → Manage Account Storage → Backups and delete backups for devices you no longer own.

Consider iCloud+ If You’re Consistently Running Low

If you’re running a 64GB or 128GB iPhone and consistently hitting the limit, the honest answer is that you need more storage — either locally (upgrade your device) or in the cloud. iCloud+ 50GB costs very little per month and unlocks iCloud Photos backup at full quality for your whole library, which takes a huge amount of pressure off device storage.
