Anyone have a list of changes that they’ve made to increase battery life? I’ve got about three hours (with 80% limit in BIOS, which I might get rid of), so I’m sure there’s a lot that can be changed.

      I think the most important ones are:

      • CPU_SCALING_GOVERNOR_ON_BAT
      • CPU_ENERGY_PERF_POLICY_ON_BAT
      • CPU_BOOST_ON_BAT
      • CPU_HWP_DYN_BOOST_ON_BAT
      • SATA_LINKPWR_ON_BAT (this had an issue where it corrupted data, but that was a few years ago so it should be fine)
      • AHCI__RUNTIME_PM_ON_BAT
      • WIFI_PWR_ON_BAT
      • PCIE_ASPM_ON_BAT
      • RUNTIME_PM_ON_BAT

      (I haven’t used these myself because I don’t have a radeon card, but it should improve battery life for you):

      • RADEON_DPM_PERF_LEVEL_ON_BAT
      • RADEON_DPM_STATE_ON_BAT

      I had to set USB_AUTOSUSPEND=0 because otherwise my usb devices kept turning off, but you might not need this.
