Limiting battery charge

Hi there. I have a asus ux433fn and I know that asus has preloaded an application on here that allows for the battery to not charge past 60% so that it's not constantly being topped off and diminishing the capacity of the battery.

Is there something similar to this that I'd be able to install or use on Debian? I was reading about TLP but I cannot find information about this on the Debian wiki. This laptop does not allow to remove the battery and I currently need use the laptop for several hours.

Thanks in advance!

Hi!   

This reddit says no. https://www.reddit.com/r/linuxhardware/ … for_linux/

Re: Limiting battery charge

Effectively I have written to ASUS but they told me that the software it only for windows systems. So there is not help from them  hmm

Can you unplug it when it reaches 60%?

Hi there. Yes, I can do that. But in that case, the battery will continue to reduce its lifespan. The application that Asus provide, on windows, stop charging the battery at particular percentage. But it seems that it’s not possible on Linux

After posting here, I kept searching for info and I found the same links you provide here, so I just installed TLP on my system. I posted here thinking that maybe you can know sometimes better/different to TLP.

Thanks you all smile

There is no difference between if windows software stops charging at 60% and start charging at 35 or manualy unplug/plug in the power... At least not when thinking about the battery.

If you want to do that, you can enable tint2 to show power percantage. Add to your tint2-config:

# Battery
battery = 1
battery_hide = 99

The last row hides the battery info as it otherwise will show on to rows, not so nice...

Maybe Assus in an long awaited future, will open share firmware code...

Re: Limiting battery charge

Funny thing - I have ThinkPad T470 and it also comes with a preloaded Lenovo software for limiting battery charge among other things.

The limits I set up in that app are binding on my second boot i.e. BunsenLabs. It was the case with Helium and also is the case with Lithium.

24Wh is the BAT0 and 71Wh is the BAT1. Both stop precisely at 89% - Windows app is set up to stop at 90%, probably some discrepancy in capacity measured or other stuff between Windows and Linux.


I don't have patience or skill to dig deep enough every time system breaks itself or when I break something because of lack of patience and skill.

This article clearly says "Thinkpads only".
It is frustrating - if a software solution exists for Windows, there should be one for Linux too.
I suggest you experiment with the utilities mentioned in that article.
But a quick search for your thread title + linux revealed nothing (positive).
