  • Restart your devices. Classic move. Restart both your Apple Watch and iPhone and try updating again.

  • Give yourself some space. Check that there's enough free space on your Apple Watch to download the update.

2. Apple Watch won't connect to my iPhone

Apple Watch not connecting to your iPhone? Let's try to bring them closer together.

  • Check Bluetooth and Wi-Fi. Make sure both your iPhone and Apple Watch have Bluetooth turned on, and that they’re connected to the same Wi-Fi network.

  • Hold them close. Make sure your iPhone and Apple Watch are close together, giving them the best chance to connect.

  • Give airplane mode a try. Here’s a top trick! Toggle airplane mode on and off on your iPhone. This can sometimes kickstart the connection process.

Does your Apple Watch refuse to charge properly? Here are some tips to try and sort it.

  • Check the charger. Use only Apple-certified chargers. Also, check for any damage or dirt on the charging cable and the back of your Apple Watch.

  • Snap your watch in place. Make sure the back of your Apple Watch is placed properly on the charger. It should snap lightly into place.

  • Reboot your watch. Press and hold the side button and Digital Crown simultaneously until the Apple logo appears. This restarts the watch.

  • Check for updates. Sometimes a software update can resolve any charging issues.
