[SOLVED] Limit battery charge to 80% on Acer Aspire A315-43 [Arch Linux]

PxRyzl · 12-14-2023, 10:58 AM

I'm wondering if it's possible to limit the battery charge to 80% on Linux.

It's already possible to do this on my laptop on windows using acer care center so I'm wondering if I could do the same on Arch Linux

I'm using kde plasma but there's isn't any battery limit option in settings and there isn't any option to do it on bios

I have that set up in my Samsung laptop, but you have to set it in the BIOS. Have you checked there? And don't ask me how - it's nearly 11 years since I set it.

Not out of the box, you can using command line by installing a kernel module (if your laptop is supported)

Code:

# echo 80 > /sys/class/power_supply/BAT0/charge_control_end_threshold
