   I find it disturbing that many articles claim "dark mode" saves battery on LCD displays. Uh, no. It doesn't. LCD display battery usage is tied to the backlight settings. Only active display tech like AMOLED, etc. save battery life in dark mode.

     @lauren there is worse. there are websites that detect that you aren't actively looking at their page and turn it “off” by making it dark to save energy.

     and then keep polling the website to detect whether the user had interacted with the page, thus preventing the device from doing actual power saving.

     @lauren I can't stand dark mode, it gives me a headache. In fact, it's the only reason I'm on Mastodon today. I tried just being a lurker, but the website defaults to dark mode. The only way to change it, is to sign up.

     @arvrrob @lauren Right, there are LCD displays that regulate the backlight based on the brightness in that zone of the screen.

     @lauren Does that apply to locally dimming LCD panels?
