Does anyone believe this? Is it real? Windows laptops always claim crazy battery life figures but when I have the latest, nicest windows machine it ends up lasting like 3-4 hours every time, with a normal coding workload. My MacBooks in contrast will last 8+.

That about fits my personal experience. The dozens-of-hours-long battery life claims for laptops are based on streaming videos, but real-life battery life is always far shorter for me, as I usually use my laptop for more intensive tasks.

I think these have new LG Oxide 1 Hz displays? That might be why it didn't fair as well in games.
