sounds like something I'd rather never want to get used to then. More expensive, uses more power so kills battery life faster and worse for the environment. Whe

  > uses more power so kills battery life faster and worse for the environment. Where's the win? Depends on the device, but often the difference is a very minimal few point percent, perhaps 3-5%. I would think it can easily be compensated for by undervolting/powerlimiting on laptops. The win is lesser eye strain/headaches for a lot of people. No harm in turning it off if you don't need it, but many do benefit.

  > uses more power so kills battery life faster not necessarily. on promotion iPhones (fancy name for variable refresh rates), the panel is not stuck at 120Hz all the time. it varies from 1Hz when the screen is static up to 120Hz when it's getting animated, down to whatever framerate your content is at (e.g. movies and videos). it actually is a battery saver whenever the phone's screen is static (common on most apps with text) or with <60Hz content (youtube, movies, etc).
