10. Delete Over-the-Air (OTA) Updates
When there’s an update available for your device, it is downloaded automatically, ready to be installed whenever you want. These OTA updates consume a lot of space, ranging from 1GB to as much as 3GB. You can save a lot of space by deleting these updates if you don’t wish to install them.
- Open Settings
- Tap General
- Tap Storage & iCloud Usage.
- Under Storage, tap on Manage Storage. From the list that opens, find the OTA update you want to delete and tap on it to open.
- Then press Delete Update.
