Prepare Your iPhone for iOS 27: Backups, Space, and App Compatibility
To prep for iOS 27, back up your iPhone (iCloud or computer), update to iOS 26 first if needed, and free about 18–25 GB of space for a smooth install. Check app compatibility with the new OS, use iPhone Storage to offload or delete unused apps and remove duplicate photos or large attachments, ensure you know your Apple ID, keep the device charged, and use a reliable Wi‑Fi connection. You might also consider waiting a short time after release to hear user feedback before upgrading.
