There are several things that you can do.
Hardware:
- Make sure USB-C cards are in the back 2 ports
Windows Settings:
- Set power setting to best battery life
- Lower screen brightness (I usually have it at 20-30% and I get 8-10 hours on my Ryzen 7 board)
- If your SSD has a power saving mode, activate it in the manufacturer’s software
- Update to latest drivers directly from AMD
- Uninstall unneeded apps
- Turnoff unneeded services in System Configuration
Power Plan Settings
- Set minimum processor state to 1%
- Set PCIE Link State Power Management to Maximum Power Savings
- Turn on USB selective suspend setting
- Set USB3 Link State Power Management to Maximum Power Savings
- Turn off Network connectivity in standby
You can also use O and O Shutup 10 to disable hidden services. Do note that since the Ryzen 5 version has a 55 watthour battery instead of a 61 watthour battery, you may still not get the same battery life as some reviews suggest.
