Battery life on NS2 is on par (even a little better) then other PC handhelds

Game for reference: Cyberpunk 2077

Switch 2:
– 720p (internal) (1080p Screen) 40fps
– Better Image Quality
– 20W battery
– 2h30min

Steam Deck Oled:
– Steam OS
– 800p 40fps
– Good Image Quality
– 50W battery
– 2h06min

Rog Ally:
– Steam OS
– TDP at 15W (lowest to maintain performance)
– 1080p 40fps
– Good Image Quality
– 40W battery
– 1h15min
– For Rog Ally X (80W battery), I'm assuming double battery life – 2h30min (or a little more)
