Which one is cheaper?

When it comes to battery life, SteamOS was yet again a very clear winner in this with even demanding titles like Cyberpunk 2077 having 1 hour 31 minutes on Windows and 2 hours 6 minutes on SteamOS. In less demanding titles like Dead Cells the difference is absolutely insane jumping from 2 hours 47 minutes on Windows to 7 hours 8 minutes on SteamOS.
