Skimming thorough the video that looks promising. Does he delve into the power levels of these machines? There's H series CPUs are rated for PL2s of 115+ watts and there's no way they're hitting those levels in those thin of machines.

Battery life is still lacking considering that those machines have bigger batteries, but it looks like a huge step up. I'm looking forward to a new P1 with these CPUs and 4000 series GPUs to potentially upgrade my P1G4, but I might hold off a bit longer for next gen USB C/Thunderbolt. Maybe with a 90 watt hour battery and those CPUs I could get more than 30minutes-2 hours of battery life.
