After @Mario_Limonciello’s post about abmlevel, I included that in my testing with the following settings & results:
- PPD power-saver, amdpstate active, epp set to power, usb autosuspend enabled, camera & mic off. Apps firefox, libre office, 3-4 terminals under continuous use.
- 10% battery usage took 1:08 for an avg 4.85W
Seeking the holy grail, enabling powertop --auto-tune made little to no difference as:
- 10% battery usage took 1:07 at an avg 4.93W draw
Based on this latest and past testing detailed here, I’ve posted a power management guide.
Happy 2024!
