Open **Settings → General → iPhone Storage**. 2. Wait for the coloured bar to load. It shows **Apps, Photos, Media, Messages, iOS** and **System Data**. 3. Below it, iOS shows **recommendations** (like "Offload Unused Apps" or "Review Large Attachments"). 4. Below that is every app, **sorted by size**. ## Quick fixes (5 minutes) ### 1. Empty "Recently Deleted" in Photos Deleted photos stay for **30 days**. - Photos → **Albums** → scroll to **Recently Deleted** → unlock with Face ID → **Select → Delete All**. ### 2. Offload unused apps Offloading removes the app but keeps your documents and data. - **One app:** Settings → General → iPhone Storage → tap the app → **Offload App**. - **Automatically:** Settings → **Apps → App Store** → turn on **Offload Unused Apps**. ### 3. Delete downloaded media Streaming apps keep downloaded episodes and songs: - **Netflix, Prime Video, YouTube:** open Downloads and delete. - **Spotify / Apple Music:** remove downloaded playlists you don't need offline. - **Podcasts:** Settings → Apps → Podcasts → set downloaded episodes to be removed after playing. ### 4. Restart your iPhone A restart clears temporary files and can shrink **System Data** right away. ## Photos and videos ### 5. Turn on Optimise iPhone Storage If you use **iCloud Photos**: - Settings → [your name] → **iCloud → Photos** → choose **Optimise iPhone Storage**. - Full-resolution photos stay in iCloud; your iPhone keeps smaller versions and downloads the full one when you open it. > **Tip:** The free iCloud plan is only **5 GB**. If your photos are bigger, you'll need **iCloud+** (it starts small and is cheap per month) or another backup like Google Photos. ### 6. Find and delete big videos - Photos → **Albums → Media Types → Videos** — long and 4K videos can be **hundreds of MB each**. - Delete ones you don't need, or move them to a computer or external drive. ### 7. Use the Duplicates album - Photos → **Albums → Utilities → Duplicates** → **Merge** to combine copies and keep the best one. ### 8. Lower the video recording settings - Settings → **Camera → Record Video**. **4K at 60 fps** uses about **400 MB per minute**; **1080p at 30 fps** uses roughly **60 MB per minute**. - Settings → Camera → **Formats** → choose **High Efficiency** (HEIF/HEVC) to save space versus "Most Compatible". ## Messages and WhatsApp ### 9. Clear Messages attachments - Settings → General → iPhone Storage → **Messages** → **Review Large Attachments**, **Photos**, **Videos** — swipe left to delete. - Set old messages to delete automatically: Settings → **Apps → Messages → Keep Messages → 1 Year** (or 30 days). ### 10. Clean up WhatsApp WhatsApp storage doesn't show in the Photos app, so it's easy to miss. 1. Open **WhatsApp → Settings → Storage and Data → Manage Storage**. 2. Review **Larger than 5 MB** and **Forwarded many times** — delete in bulk. 3. Open each big chat and delete media you don't need. 4. Turn off **Save to Photos** (Settings → Chats) so every forward isn't saved twice. 5. Set **Media auto-download** to "Wi-Fi" or "Never" for videos. ## Deeper clean-ups ### 11. Clear Safari and app caches - **Safari:** Settings → Apps → Safari → **Clear History and Website Data** (this signs you out of websites). - Apps like **Instagram, TikTok, Telegram, Chrome and Google Maps** can store large caches. Some have a "Clear cache" option in settings; otherwise **delete and reinstall** the app. - **Telegram:** Settings → Data and Storage → **Storage Usage → Clear cache** and set **Keep media** to a shorter time. ### 12. Shrink "System Data" (Other) **System Data** includes caches, logs, Siri voices and temporary files. If it's very large (20 GB+): 1. **Restart** the iPhone. 2. **Update iOS** (Settings → General → Software Update). 3. **Clear Safari data** and big app caches (see #11). 4. **Delete old Siri voices** or offline translation languages you don't use. 5. As a last resort: **back up**, **Erase All Content and Settings**, and **restore** — this usually shrinks System Data a lot. ## How much space should you keep free? Keep at least **10–15%** free. iOS updates often need **5–8 GB** of free space to install. When storage is nearly full, the camera, apps and even typing can slow down. ## When it's time for more storage If you've cleaned up and are still always full: - **iCloud+** or **Google One** for photos and backups. - A **USB-C flash drive** (iPhone 15 and later) or Lightning drive to move videos off. - Next time, choose a phone with **256 GB or more** if you shoot lots of video. ## Frequently asked questions ### Why is my iPhone storage full when I've deleted photos? Deleted photos stay in "Recently Deleted" for 30 days. Empty that album to free the space. ### What does "Offload App" do? It removes the app but keeps its documents and data. Reinstalling restores everything. ### How do I reduce System Data on iPhone? Restart, update iOS, clear Safari and app caches, and delete unused offline content. Erasing and restoring from a backup shrinks it the most. ### Does deleting WhatsApp chats free up space? Yes, especially chats with lots of media. Use WhatsApp's Manage Storage tool for the biggest files. ### Will Optimise iPhone Storage delete my photos? No. Full-resolution originals stay in iCloud; the iPhone keeps smaller versions. ### How much storage does iOS need? iOS itself takes around 10–15 GB, and updates need several GB of free space to install. ### Is it safe to clear Safari history? Yes, but it signs you out of websites and removes saved site data. ## Sources - [Apple Support — How to check the storage on your iPhone and iPad](https://support.apple.com/en-us/108429) - [Apple Support — Manage your iCloud storage](https://support.apple.com/en-us/108922) - [Apple Support — Use iCloud Photos](https://support.apple.com/en-us/108782)
