My iPhone storage is full. What should I do?
Photos and videos are usually what fill an iPhone. You can free up space without losing them by keeping the full-size copies in iCloud and smaller copies on the phone.
To free up space:
1. Open Settings, General, iPhone Storage to see what is using the space.
2. Turn on iCloud Photos and choose Optimise iPhone Storage. You may need a larger iCloud plan if you have a lot of photos.
3. Delete apps you no longer use, and clear old WhatsApp videos under WhatsApp, Settings, Storage and data.
4. Empty the Recently Deleted album (deleted photos sit there, still using space, for 30 days).
We free up space safely, back up your photos first and show you how to find them afterwards, at your home in Swindon. See Phone Storage Full & Photo Clean-up.
