That's 4 hours of running the screen (by far the biggest power drain) and doing stuff, it ain't no M*-powered Macbook but to me that's impressive and in the realm of practicality.

My prior experiences with older hardware have been barely an hour or two, which is impractically retarded.

I also have an M2 Macbook Air and find its battery life even more impressive (literally days between charging), but I don't really use it because it doesn't satisfy my requirements which include games (for play) and clean interoperability with other Windows machines at home (for both play and work).
