Digging around in system settings in iOS is a chore, but Siri allows you to quickly toggle some of those settings a bit quicker. After you bring up Siri, you can have it toggle a variety of settings, though which ones work and which ones don't are a bit baffling and inconsistent. Here are all the toggles we found that you can flip with Siri by saying "Turn off" or "Turn On":
- Aeroplane mode (on but not off, since Siri will stop working once it's enabled)
- Increase/Decrease screen brightness
- Low power mode
- Cellular data
- Do not disturb
- Invert colours
Thankfully, while which toggles work and which don't might seem inconsistent, you can also always get directly to any setting in the Settings app by simple saying, "Open Settings for [setting you want]".
