Note: Before you update, set up iPhone to back up automatically, or back up your device manually.

Update iPhone automatically

If you didn’t turn on automatic updates when you first set up iPhone, go to Settings > General > Software Update > Automatic Updates, then turn on Automatic Updates.

Go to Settings > General > Software Update > Automatic Updates, then turn off Automatic Updates.

At any time, you can check for and install software updates. Go to Settings > General > Software Update. The screen shows the currently installed version of iOS and whether an update is available.
