PSA: Siri Can Turn on Night Shift on Apple Watch

The Apple Watch has a hidden feature for activating Night Shift on the device, a Reddit user discovered recently. If you ask Siri on the Apple Watch to turn on ‌Night Shift‌, ‌Siri‌ will do so, and the display will take on the dimmer, yellow hue that lowers blue light exposure.

It is not clear how long ‌Siri‌ has been able to activate ‌Night Shift‌ on the Apple Watch, but it seems to be recent. Apple has no documentation on ‌Night Shift‌ on Apple Watch, and it was not previously a watchOS 10 option. It's possible ‌Night Shift‌ is tied to watchOS 11, but it is not limited to devices running ‌watchOS 11‌. We were able to use the feature on an Apple Watch Series 9 with ‌watchOS 10‌ installed.

Activating ‌Night Shift‌ can only be done through ‌Siri‌, and there is no toggle in the Apple Watch Settings app or elsewhere on the device. ‌Siri‌ mentions scheduling ‌Night Shift‌ in the Settings app, but that's not an option at the current time in ‌watchOS 10‌ or ‌watchOS 11‌.

‌Night Shift‌ does not appear to be available on all Apple Watch models, with Reddit users unable to activate it on a Series 5 and lower.

The option to suddenly turn on ‌Night Shift‌ without an accompanying setting suggests that it is a feature that has been accidentally introduced, and the toggle could be introduced in a future version of ‌watchOS 11‌ or an upcoming ‌watchOS 10‌ update.

As a night owl, this is such a welcome change on my Ultra 2! It also shifts the flashlight to a warmer white tone

Are people staring at a watch so much that they need this?
Probably not but it always bugged me having my Apple watch be a different color temperature than my phone screen.

It’s like having soft white and daylight bulbs in the same room ***cringe***

"Gazing at a screen that emits “blue light” before bed doesn’t seem to have a significant effect on sleep, scientists have said after reviewing the evidence."

Whether or not it has an impact on sleep, it is definitely more comfortable on my eyes to have a warmer display later at night.

Doesn't work on my Apple Watch SE 2.
I got it to work on my SE 2 by saying "turn on Night Shift". Weirdly, it didn't work the first time -- it just replied "night night" (cute) and didn't do anything else. I did it again and it worked.

Not the first time I've had inconsistent results from the same command with Siri. My working theory is that requests can go to different servers, which may have slightly different programming? Honestly who the hell knows. I just hope it gets smarter at some point.
