The Tech Report published a review on the Heres a first look at the battery life of HP's Ryzen-powered Envy x360

A quote from the article:

My initial tests of AMD's Ryzen 5 2500U APU gave us a fine picture of the APU's performance, but we admittedly didn't test battery life in that initial article. Part of the reason for that omission was to avoid drawing unfair comparisons between the 15.6" HP Envy x360 that plays host to the Ryzen 5 2500U and the 14" Acer Swift 3 machines we used to represent Intel's Core i5-8250U.

Although the jump in screen size might not sound large on paper, the practical effects of the Ryzen system's bigger screen on battery life are likely quite significant. Getting the same light output from a bigger panel requires more power, as just one variable, and the HP system also has a pen digitizer in its LCD panel with unclear power-management characteristics.
