@mmstick@lemmy.world I had a feature request, but I wasn’t sure if it belonged here or sent directly to System 76.
It would be wonderful if we could configure the maximum battery charge level. Many people (myself included) leave our laptops plugged in, and I am relatively confident it is bad for the battery to let it set at near 100% or at 100% essentially forever.
I suspect this would require a firmware update, and I don’t know if it would only be possible with the new laptop System 76 being developed from the ground up.
Anyway, I just wanted to throw it out there as I think it would be a great feature.

The vendor would have to expose a system file for configuring this in the kernel, and then contribute a patch to the cosmic-power applet to connect it with the existing toggle.
That said, I would be surprised if the battery manufacturer isn’t already limiting the max charge to 80% from the firmware in the battery’s own charging controller.
I love this feature on my surface go. You set it to kiosk mode in the bios and the battery stays at 50%. I also keep the battery save feature on my phone on to Max charge to 85%. Unfortunately I think is a hardware level thing. It has to be part of actual circuitry/charge controller chip.
Yeah a number of laptop brands supports it, it can often be set with commands such as “sudo tlp setcharge 70 90 BAT0”, but as far as I can see system76 doesn’t support tlp as they have their own solution.
I am adding an update to this post that this is already supported for System 76 laptops! See https://support.system76.com/articles/laptop-battery-thresholds/ for more details.
