+laptop (browsing, downloading articles), and the battery level only dropped from
+~90% to ~40% within 3 hours. Some system update, be it a kernel update or some
+other software running in the background, must have reduced energy consumption
+considerably :-)

+different ball park, and even some of my own Thinkpads used to do better, but
+I'm overall quite happy with battery life on this machine with bright 3k display
+and dedicated GPU. I _could_ have bought a machine which can run on battery like
+forever, but that's not my use case and plus, I'd never buy anything else but a
+Thinkpad...)
