Discussing battery life:
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.
Considering how indie friendly the deck is, this is a huge loss for MS. All other things equal that difference would easily make me drop windows.
How big is the battery on the legion go? The deck鈥檚 battery drains so quickly I wouldn鈥檛 be surprised if it couldn鈥檛 last 7 hours even in the home screen.
I鈥檝e gotten over 12 hours playing Stardew Valley on my Deck with the wattage down to 2W, something wrong with yours? lol
According to a PC Gamer article, it has a 55.5 Wh battery. https://www.pcgamer.com/hardware/handheld-gaming-pcs/lenovo-legion-go-s-windows-review/ (This one is for the Windows version but the SteamOS version has (or may have) similar hardware.)
So 7 hours on that battery would be approximately 5 hours on the deck.
I鈥檒l download dead cells here to see how long the deck can run it in one charge, but I doubt it鈥檒l reach anywhere close to five hours with the default settings.
Edit: I was wrong. Got six hours out of it even.
