I don't see why it wouldn't? I have a 16" MSI laptop with an 11th gen Intel processor (known for horrible battery life), I use Arch/Hyprland and it gets 5-6 hours with a battery degraded to 68%. Which is still in the ballpark of what most users said they got on Windows when this model was new.

Linux battery life is fine and on par with (or possibly better than) Windows these days if you don't do anything silly (I'm sure some distro and DE consume silly amounts of power just because, but it doesn't have to be that way).

Based on reports about Panther Lake, the new process, plus a 13" screen and large-ish battery, I believe the battery life claims.
