Over-the-air update steps
To use over-the-air updates, connect to Wi-Fi, go to Settings, tap General, then Software Update, review the available update, and tap Download and Install after reading the size and release notes.
Update via iTunes or Finder
For users who prefer a wired approach, connect iPhone 6 to a computer, open iTunes on macOS Catalina and earlier or Finder on macOS Big Sur and later, select the device, and choose Check for Update to download and install the latest compatible build.

Common issues after installing software update iphone 6
Performance changes
Some users notice slower performance or reduced battery life after updating, particularly when moving toward the upper iOS versions unsupported by iPhone 6, so it is important to install only the final compatible release such as iOS 12.5.7.
Connectivity and sync problems
Occasionally Wi-Fi, Bluetooth, or cellular settings may reset or behave erratically after an update, requiring a toggle Airplane Mode, reset network settings, or re-pairing accessories to restore normal function.
App-specific behavior
Certain apps may refuse to launch or display error messages if they expect a newer iOS version than iPhone 6 can provide, in which case checking for app updates or removing and reinstalling the app often resolves the issue.
FAQ
Why does my iPhone 6 say an update is available but will not install?
The update may be for a higher iOS version than iPhone 6 supports, or your device storage may be insufficient; ensure you have at least a few gigabytes free and install only the final officially supported build for iPhone 6.
What should I do if my phone restarts repeatedly during software update iphone 6?
Repeated restarts usually indicate a failed installation; try updating again while connected to power and Wi-Fi, or restore through iTunes or Finder using an official firmware file for your device model.
Can I skip an iOS version when updating my iPhone 6?
Apple does not allow skipping major iOS versions, so you should install updates sequentially; rely on over-the-air updates or iTunes/Finder to move safely to the latest supported release for iPhone 6.
Will updating to the latest supported iOS break my carrier settings or iPhone 6 functionality?
Carrier settings are updated separately and usually improve connectivity; sticking to the final supported iOS version for iPhone 6 maintains balance between security, stability, and feature support without breaking core functionality.
