Purpose

Maximize battery life. Reset the battery if it fails to hold charge.

Expected Battery Life

The Kubuntu Focus has a 62Whr battery. Over 20 changes optimizations are employed to extend battery life. The most obvious are listed below:

New batteries will last around 8 hours when doing nothing on Intel graphics and the dimmest screen settings. With modest use, a full charge should provide up to 5 hours with the Intel iGPU, or 2.5 hours with the Nvidia dGPU. This will vary depending on the applications used and the battery condition.

Maximize Battery Life

Most people need to use browsers, cloud drives, IDEs, and other apps that can draw power quickly. Here are steps you can take to maximize battery life.

Troubleshooting

Q: Sometimes the battery will not fully charge. The battery meter may report only 5 or 10% charge and not increase from there. How can I fix this?

A: Perform a battery reset shown below. Make sure the battery is discharged using the BIOS and not the OS. The latter has protections that will prevent this procedure from working.

After this procedure battery should attain 90-100% charge. The capacity available will depend on age.

Q: I see the Model 1 comes with a 62Whr battery. What battery life should I expect?

A: The Focus has over 20 adjustments to improve battery. Key optimizations include dGPU power, the keyboard LEDs power, screen brightness, and CPU boost clocks. Tests have shown new batteries will last around 7 hours when doing nothing on Intel graphics. A full charge should provide up to 5 hours with the Intel iGPU or 2.5 hours with the Nvidia dGPU. This will vary depending on the applications you are running and battery age.

Q: I use IntelliJ, WebStorm, PyCharm or other Jetbrains IDE. I’ve noticed they really reduce battery life. How can I improve this?

A: Click on File > Power Save Mode. This should provide a noticeable boot in battery life.

Q: I’ve noticed that battery life can vary. What are some things I can do to improve it?

A: Some applications draw much more power than others. IntelliJ IDEs are discussed above. Other computationally or graphically intensive apps can draw the battery down quickly. Good example include benchmarks and games. Browsers are are also notorious for draining the battery. If you don’t need a browser open, close it. If you do, keep the number of open tabs to a minimum.
