It's worth noting the engineers actually seemed to get management to allow the 2019 model to be _thicker_ with more thermal mass than the earlier models. But in a sense, Intel's chips have never been amazing for laptops.

The power draw drains batteries, and the heat is... very annoying at best. I have used a couple ThinkPads and a Dell XPS over the past 5 years too, and all of them had the same issues where they'd constantly be pushing out very hot air, and the battery life was never more than 4-6 hours.
