Battery life on stand-alone window managers Recently I bought a new laptop and installed my setup (arch linux and bspwm). And I realized that battery life was better on Windows. So, I installed tlp and other known things like powertop. But it still wasn't enough. Then I installed Kde Plasma and battery life on that was much better than windows and Bspwm. Why? Isn't it heavier than bspwm? How my battery lasts for 7 hours in KDE while it lasts for 3 hours on bspwm?
