If you're using a laptop with the Intel Wi-Fi 6 AX200 card and you've noticed that your battery life isn't what it should be, the culprit might be higher-than-expected power consumption by your WiFi card. This blog post will guide you through the steps to diagnose and fix this issue on Ubuntu.

Step 1: Detect High Power Consumption with PowerTOP

The first step in diagnosing power issues is to identify which components are consuming the most power. PowerTOP is a useful tool for this.

Install PowerTOP:

sudo apt update sudo apt install powertop

Run PowerTOP:

sudo powertop

Navigate to the 'Device stats' tab to see power consumption by device. If your WiFi card is consuming more power than expected, proceed to the next steps.

Step 2: Check the Power State of the WiFi Card

Open a terminal and run the following command to check the power state of your WiFi card:

cat /sys/bus/pci/devices/0000:3b:00.0/power_state

If the output is D0, the device is fully powered on. We'll aim to change this to a lower power state.

Step 3: Check Your Power Management Settings

Ubuntu uses either its default power management or TLP for more advanced power management. If you're already using TLP but still experiencing high power usage, you might need to install the TLP Radio Device Wizard (tlp-rdw).

Install TLP and TLP RDW:

sudo apt update sudo apt install tlp tlp-rdw

Start TLP:

sudo tlp start

This should automatically apply various power-saving settings, including those for your WiFi card.

Step 4: Fine-Tune TLP Configuration (Optional: Use TLP UI)

If you want to fine-tune your power settings, you can manually edit TLP's configuration file or use TLP UI for a graphical interface.

Install TLP UI:

sudo apt install tlpui

Run TLP UI:

tlpui

Note: If you encounter issues with TLP UI not finding the configuration files for TLP 1.6, you can manually download them from the TLP GitHub project page and place them in the expected directory.

Conclusion

By following these steps, you should be able to significantly reduce the power consumption of your Intel Wi-Fi 6 AX200 card on Ubuntu. In our example, we were able to reduce the power usage from over 4W to just 1.7W, which can make a significant difference in battery life.
