The battery life is a straight up lie. 8 hours on a single battery charge? What game were they testing, Solitaire?
If it can do low-resource gaming for 8 hours, its not lie. And honestly, thats not something too far-fetch.
The only one lying here is you, since its not even released yet for you to test the claim. Not to mention how you conveniently left out "2-" from the battery life range
What? Did you expect to run Cyberpunk 2027 for 8 hours on single charge this machine?
