You cannot directly adjust the brightness of the Apple Watch Ultra 2 using Siri. While you can ask Siri to turn off auto-brightness, this action does not allow for manual brightness adjustments afterward. Users have reported that when auto-brightness is disabled, the watch locks into the brightness level that was set at that moment, preventing further manual changes[1][3][5].
To adjust the brightness on your Apple Watch Ultra 2, you need to do it manually through the device's settings or via the Apple Watch app on your iPhone. Hereâs how:
1. Using the Watch:
- Open the Settings app on your Apple Watch.
- Tap on Display & Brightness.
- Adjust the brightness using the slider or by turning the Digital Crown.
2. Using the iPhone:
- Open the Apple Watch app on your iPhone.
- Tap on My Watch > Display & Brightness.
- Adjust the brightness level as desired.
If you want to use Siri for related tasks, you can ask her to turn off auto-brightness, but keep in mind that this will not enable manual adjustments afterward[3][6][9].
