Note no mention of battery life. Look at the internals and you'll see why - the battery is absolutely tiny, and the logic board, disk, and fans are comparatively massive. The parts are definitely not power-friendly either. Seems very optimized for staying plugged in, with only a quick unplug to go into a meeting. My guess is it'll do ~3hrs w that 55Wh battery at most. This competes with gaming laptops and not MBPs, though it does look nice.
