Step by step
Connect to a reliable power source
Plug your iPhone into a wall outlet. Software updates consume significant battery life, and the process will pause if the device power level falls below 50 percent.
Note: A wired connection is preferred over wireless charging pads for consistent power delivery.Verify your Wi-Fi network connection
Open Settings and tap Wi-Fi. Ensure you are joined to a stable, private network, as cellular data cannot be used to download iOS system updates.
Check for available software updates
Navigate to Settings, tap General, then tap Software Update. The iPhone will automatically query Apple servers to check for the latest firmware version.
Download and install the latest iOS
Tap Download and Install if an update is available. Enter your device passcode when prompted to authorize the system change.
Note: The device will restart automatically once the installation completes.Confirm the software version
Return to Settings, select General, and tap About. Confirm the iOS version matches the target device requirements for data migration.
Note: Always update the destination device to the same version to avoid migration failures.
