Always on display, or AOD, has been with us now for over ten years, and it’s something I always turn off because I frankly think it’s one of the most wasteful and pointless features of modern phones (though you can customize it with themes). There’s a 10-15% hit to battery life while running AOD, no matter the phone (and on Samsung phones, it’s part of a suite of features you don’t need), but what’s even worse is that AOD is a pointless, distracting feature: why must your phone screen be on all time to persistently show you the clock and a few notification icons? If you have a smartwatch, AOD is especially redundant since you can see this same info if you just glance at your wrist.
