How to Free Up 10GB on Your iPhone Today (Step by Step)

Running out of iPhone storage? Here's a step-by-step plan to reclaim 10GB or more today — without permanently losing a single photo.

Getting 10GB back on your iPhone in a single session is more achievable than it sounds. Most people have multiple gigabytes of screenshots they'll never look at, burst photos from years ago, and cached app data they don't know exists.

Here's the fastest path to 10GB of reclaimed space, ranked by expected return.

First: See Where Your Storage Is Actually Going

Before deleting anything, find out what's taking the most space:

Open Settings → General → iPhone Storage
Wait for the bar chart to load — it takes a moment to calculate
Look at the breakdown below the bar: Photos, Apps, Messages, System Data

Photos is almost always the biggest category. That's where most of your 10GB will come from.

Step 1: Delete Screenshots (Expected: 500MB–2GB)

Screenshots are the fastest win because almost all of them are already useless.

Open Photos → Albums → Screenshots
Tap Select
Scroll through and tap any you still need to keep
Tap the trash icon and confirm

Most people delete 80–90% of their screenshots in one pass. If you have a few years' worth, this alone can be 1–2GB.

Time required: 5–10 minutes

Step 2: Clean Up Burst Photos (Expected: 1–5GB)

Burst mode takes 10+ shots per second. Every burst is a cluster of nearly identical photos — and most people have hundreds of them.

Open Photos → Albums → Bursts
Tap into each burst
Tap Select, choose your best shot, tap Done → Keep Only 1 Favourite

If you have a lot of bursts, the Migrate Moments iOS app speeds this up significantly with a swipe-based review that's much faster than the native Photos interface.

Time required: 15–30 minutes, depending on how many bursts you have

Step 3: Use the iOS Duplicates Tool (Expected: 500MB–3GB)

Since iOS 16, iPhone has a built-in duplicate photo finder:

Open Photos → Albums → Utilities → Duplicates
Tap Merge All
iOS keeps the highest-quality version of each pair and deletes the rest

This handles exact duplicates only — photos that are byte-for-byte identical. It won't catch similar shots taken a second apart.

Time required: 2–5 minutes

Step 4: Delete Old Videos (Expected: 1–10GB)

Videos are the single largest file type on most iPhones. A minute of 4K video is around 400MB.

Open Photos → Albums → Videos
Sort by largest or oldest
Delete anything you've already watched, shared, or don't need to keep

Old concert clips, clips of the kids that are already backed up somewhere, videos you recorded to send someone — these are usually safe to delete.

Time required: 10–20 minutes

Step 5: Offload Unused Apps (Expected: 1–5GB)

Apps you haven't opened in months — especially games — can take several gigabytes.

Go to Settings → General → iPhone Storage
Scroll down the app list — iOS shows when you last used each app
Tap any app you don't need → Offload App (removes the app but keeps its data) or Delete App (removes everything)

Alternatively, go to Settings → App Store and turn on Offload Unused Apps — iOS will automatically offload apps you haven't used in a while.

Time required: 5 minutes

Step 6: Clear Message Attachments (Expected: 1–3GB)

Photos and videos sent and received in Messages are stored separately from your Photos library.

Go to Settings → General → iPhone Storage → Messages
You'll see Top Conversations and a breakdown by attachment type
Tap Review Large Attachments and delete what you don't need

You can also set messages to auto-delete after 30 days or 1 year: go to Settings → Messages → Keep Messages.

Time required: 5 minutes

Step 7: Empty Recently Deleted (Immediate payoff)

Deleted photos don't disappear immediately — they sit in Recently Deleted for 30 days and still count against your storage.

Open Photos → Albums → Recently Deleted
Tap Select → Delete All
Confirm

This is the step people forget. Do it immediately after cleaning up photos and your storage numbers will update within a few minutes.

Time required: 1 minute

Expected Total

Step	Low estimate	High estimate
Screenshots	500MB	2GB
Burst photos	1GB	5GB
Exact duplicates	500MB	3GB
Old videos	1GB	10GB
Offloaded apps	1GB	5GB
Message attachments	500MB	3GB
Total	4.5GB	28GB

Even the conservative numbers put you well over 10GB. Most people land between 8–20GB depending on how long their library has been accumulating.

After the Cleanup

Once you've freed the space:

Check your iCloud storage — if you deleted a lot of photos, your iCloud usage will also drop (allow 15–30 minutes)
Consider dropping your iCloud plan — if you're now well under your tier, downgrade and save money
Archive older photos — if you want to keep freeing up space ongoing, the Migrate Moments Mac app at migratemoments.app/download exports older photos to an external drive so you're not paying iCloud for photos from 5 years ago

Frequently asked questions

How do I quickly free up iPhone storage? The fastest wins are: delete screenshots (Photos → Albums → Screenshots), clean up burst photos (Albums → Bursts), and run the built-in Duplicates tool (Albums → Utilities → Duplicates). These three steps alone usually free 3–8GB in under 30 minutes.

Will freeing up iPhone storage also free up iCloud storage? If iCloud Photos is enabled, yes — deleting photos on your iPhone also removes them from iCloud (after a 30-day Recently Deleted window). Go to Recently Deleted → Delete All to make this immediate.

How do I check what's using the most storage on my iPhone? Go to Settings → General → iPhone Storage. The bar chart at the top shows the breakdown by category. Tap any app in the list below to see more detail and offload or delete it.

Why is my iPhone storage full even after deleting photos? Deleted photos stay in Recently Deleted for 30 days and still count against storage. Go to Photos → Albums → Recently Deleted → Delete All to permanently remove them and reclaim the space immediately.

How much storage do burst photos take up? It varies by how many you have, but each burst can be 10–30 photos at 3–8MB each. 100 bursts is 3,000–8,000 photos — easily 10–60GB. Burst cleanup is one of the highest-return storage recovery steps.
