View Full Version : Battery Threshold

5th October 2017, 07:19 PM
Hi, im Running Fedor 26 on my asus Zenbook3 UX390

when i was running windows i noticed that the battery did not charge over 98%
so it would trickle charge between 93-98.

I have installed TLP and powerto.

I tried with TLP first and noticed most of everything was for thinkpads
and i could not get close with powertop

can anyone help me set a battery threshold.

Thank you

I have an old laptop that never shows the battery as 100%, although it did when I bought it. A friend of mine who knows hardware tells me that sometimes components change their values slightly, and that this is probably all that's happened. As long as it holds enough charge to work and consistently goes up to almost 100%, don't worry about the reading.

Have a look at the files under /sys/class/power_supply/BAT0/, you'll find max charge, current charge etc in there.
