Found a nice tool showing that it is running at much to high clock speed for doing nothing. With energy savings activated in the GNOME settings.
cpupower frequency-info analyzing CPU 2: driver: acpi-cpufreq CPUs which run at the same hardware frequency: 2 CPUs which need to have their frequency coordinated by software: 2 maximum transition latency: Cannot determine or is not supported. hardware limits: 2.20 GHz - 4.95 GHz available frequency steps: 3.70 GHz, 2.80 GHz, 2.20 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 2.20 GHz and 3.70 GHz. The governor "schedutil" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 4.06 GHz (asserted by call to kernel) boost state support: Supported: yes Active: no -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2064847 Title: Power consumption much higher after switching to Ubuntu 24.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/2064847/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
