Haven't phones, watches and tablets been using low refresh rates to enable battery improvements for a while? The Apple Watch Series 5 (2019) has a refresh rate down to 1Hz. M4 iPad Pro lacks always-on display despite OLED panel with variable refresh rate (2024): https://9to5mac.com/2024/05/09/m4-ipad-pro-always-on-display...

this is just regurgitating the manufacturer's claim. I believe it when I see it. Most of display energy use is to turn on the OLED/backlight. They're claiming, because our display flickers less, it's 48% more efficient now.
