Note: Your device must be plugged in to a power source in order to update wirelessly. Before you update, back up your device to iCloud or Finder. Updates may download automatically while your device is connected to Wi-Fi and a power source. If an update is available, select Download and Install and follow the prompts. If you use a passcode, you'll need to enter it before installing the update. To turn automatic software updates on or off, select Automatic Updates then select the 
 Download iOS Updates switch or  Install iOS Updates switch as desired. 
3. If you can’t update wirelessly or if you want to update with Finder, connect the device to the computer using the included Lightning-to-USB cable. 
4. Open 
 Finder on your computer.
5. Click the desired Device pane, then click Check for Update.
Note: If your device is on the current software version, click OK. If an update is available, click Update and follow the prompts. If you don't have enough free space to update using Finder, you'll need to delete content manually from your device. Find out what to do if you get other error messages while updating your device.
