After a series of horrible fuckups (and I’m not using this word lightly here) by Lenovo, they’ve finally replaced my laptop with a 2nd gen X1 Yoga. I’ve finished building Plasma from git (which I need for development work) and thought to give powertop a whirl to check how we’re doing in terms of battery life. I’m very pleased with the results: An idle Plasma Desktop doesn’t wake up the CPU, which is something we worked on avoiding for years. Furthermore, idling, I get a battery drain rate of less than 4 watt, which is pretty exceptional. Bottom line: Our work hasn’t been in vain and shows that Plasma is pretty well optimized to get the most out of your battery. This is especially interesting for Plasma Mobile of course, but benefits laptop users as well. It’s a nice example how our work on convergence benefits all users. And polar bears.
