How is the battery protection different from generic limits? about matebook-applet HOT 8 CLOSED

The trick is to stop charging at the desired level to avoid prolonged periods of running on a full charge (in case you're in the habit of working while plugged in) to preserve the battery.

As far as I understand, the built-in KDE facilities for limiting the maximum battery charge rely on the tlp software to work. tlp supports a limited number of laptop models, most of them Lenovo Thinkpads, and is currently incompatible with the Huawei-WMI driver that is used to control this feature in Matebooks.

I haven't been able to make KDE's builting battery charge limiter work with my laptop, or I would hardly go through all the hassle of developing matebook-applet in the first place. If you have been able to make it work, or know someone who has, could you please write up about it for the Linux support repository?

Oh, I really didn't do anything special. I'm running Ubuntu Jammy (I guess it's a Prerelease/Beta). In KDE I go to "Advanced Power Settings" and there is a section called "Charge Limit" with two fields "Stop charge at:" and "Start charging only once below:" . You input percentages. So I put in 70% and it seems to never go past that number.

I don't think it's lying b/c when I reboot into the Windows partition it seems to be at 70% (I will double check this later).

What's your Matebook model?

Matebook 16

Hmm, I wonder how exactly it differs from the older models, so that it is supported by KDE's builtin charge limiter.

It's good to know the newer models are more Linux-friendly!

I've never had a computer not be able to display the current battery level. Or is the issue programmatically stopping the charging once it hit a target charge percentage? (I can see how that would require a custom driver)

And yeah, since it's quite difficult to get this model at the moment - I'd expect very few eyeballs on this issue. I had to custom order it from China through Tabao (which turned out to really be worth it - the thing is amazing).

Thank you for your project nonetheless :)

Gotcha. Yeah, it seems obvious in retrospect haha. Thanks for clarifying. You need something in circuit for the software to tell the charger to stop :) Alright, I'll close the issue. Appreciate the insight
