How to Clear Space on Your iPhone Without Deleting Photos

Are you constantly battling that “iPhone Storage Full” warning but can't bear the thought of deleting your photos? You're not alone.

Thankfully, there are several smart, non-destructive ways to clear space on your iPhone in 2025 — and still keep every memory safe.

In this guide, we'll show you how to:

• Reclaim storage without touching your camera roll

• Optimise storage using iCloud

• Clear hidden clutter from apps and files

• Avoid costly storage upgrades unnecessarily

Let’s dive in.

🧼 1. Clear Safari Cache and Browsing Data

Your web browser quietly stores tons of data in the background.

To clear it:

• Go to Settings > Safari

• Tap Clear History and Website Data

This won’t delete saved passwords or bookmarks but can free up hundreds of MBs, especially if you browse frequently.

🗑 2. Offload Unused Apps (Without Losing Data)

Instead of deleting apps, try offloading them. This removes the app itself but retains the data — so when you reinstall it later, everything is still there.

Go to:
Settings > General > iPhone Storage
Tap on any unused app and choose Offload App

To automate this, enable:
Settings > App Store > Offload Unused Apps

📱 3. Remove Old iMessage and WhatsApp Media

Messaging apps like iMessage and WhatsApp can store years of photos, videos, and voice notes in the background.

iMessage:

• Go to Settings > General > iPhone Storage > Messages

• Clear Large Attachments and Old Conversations

WhatsApp:

• In WhatsApp, go to Settings > Storage and Data > Manage Storage

• You’ll see media-heavy chats and large files — delete them without losing the conversation.

☁️ 4. Optimise iPhone Photo Storage with iCloud

This tip keeps all your photos while saving space locally.

Enable:
Settings > Photos > Optimise iPhone Storage

What it does:

• Full-resolution images are stored in iCloud

• A smaller, device-friendly version remains on your phone

• You save GBs of space without deleting a single photo

Note: You’ll need enough iCloud storage (50GB+ plan recommended)

🎞 5. Delete Downloaded Videos, Netflix & Spotify Files

Streaming apps store downloaded media locally — often without you realising.

• Open apps like Netflix, Spotify, YouTube, Apple TV

• Check Downloads or Offline Content

• Delete anything you’ve already watched or no longer need

You could free up gigabytes in seconds.

📦 6. Clear “Other” Storage (Now Called System Data)

This is the most mysterious category on iPhones. It includes:

• Cache

• System logs

• App data and temporary files

Unfortunately, you can't fully delete System Data manually, but here’s what helps:

• Restart your iPhone

• Delete old Safari and app cache (see above)

• Backup your iPhone and perform a factory reset (last resort – speak to a technician before doing this)

🔋 7. Manage Mail App & Attachments

If you use the Apple Mail app, it stores attachments and entire message histories.

To reduce storage:

• Open Settings > Mail > Accounts

• Reduce sync history (e.g. change "Mail Days to Sync" to 30 days)

• Delete old or archived mail directly in the app

🧩 8. Delete Duplicate Files in the Files App

Go to the Files app and check for:

• Old downloads

• Duplicate PDFs

• Saved documents from email attachments

Sort by size and delete anything unnecessary.

✅ Bonus: Use Third-Party Apps to Scan for Space Hogs

Apps like Phone Cleaner, Gemini Photos, or Cleaner for iPhone can help identify:

• Duplicate photos

• Blurry shots

• Large files or unused apps

Use them carefully and always back up before deleting.

🔧 Still Low on Space?

If your iPhone still feels sluggish or full, it may be time for a diagnostic check or battery replacement. Slower performance and storage issues can also be caused by:

• Ageing batteries

• App corruption

• Outdated iOS versions
