Windows:
- Brightness set to 20-30%
- Set power mode to best power efficiency
- Turn off bluetooth
- Uninstall unused apps
- Disable unused services
(Another thing you can do is disable location tracking but I like to leave it on for Find my Device) - Set Samsung 990 Pro to maximum power saving in Samsung Magician (You will lose some capacity if you do this)
Power Plan Settings:
- Enable primary nvme idle timeout and set that 100 ms on battery
- Minimum processor state to 5%
- Link state power management to maximum power savings
- Sleep and screen off in 3 minutes
- Enable USB selective suspend
- Enable maximum power savings for USB 3.1
AMD Adrenaline
- Power savings for iGPU
BIOS:
- Power button led to minimum brightness
- iGPU configuration to “auto” (Not sure if this affects power consumption but it does reduce RAM usage)
Another app you can use is O&O Shutup 10 which allows you to disable some hidden services.
