Battery Health Dropping 1% almost every day while plugged in

Hey guys, i’ve installed manjaro more or less 2 months ago and the thing is…until manjaro, my laptop baterry had 98% health after 4 or 5 months using Linux Mint. Now it’s 88% and 5 days ago it was 93%
I don’t have a clue why this is happening since i’ve always used it the same way(plugged in).
The laptop has only 6 months of usage.

Additionally, yesterday i noticed that even though i was using it on AC, the battery was discharging.

With powertop this is the higher power consumption
Power est. Usage Events/s Category Description
13.7 W 3,3 pkts/s Device Network interface: wlp8s0 (iwlwifi)

If the battery health continue to drop this fast, pretty soon (1 or 2 months) i won’t have battery anymore and this could be a good reason to change back to mint or windows(nightmare) as fast as i can. I don’t like this idea, because i really like manjaro, but i’m quite upset about my battery.

I get this impresion that all that started after the latests updates
Could you please help me find out if it’s related to my SO? I hope it’s not!!

I doubt this is software related, I’ll say the most probable cause is a faulty battery.

There are some factors the influence battery longevity negatively:

  • High temperature
  • Charge/discharge cycles
  • Battery left fully discharged for extended periods of time.

I’m not sure about these 3 things.

I’ve never let it fully discharge and most of the time i’m using it plugged in.
Temperature is ok! Lately most of my activity is text editing.

I understand batteries weren’t made to last sooo long, but just to have an idea, yesterday it was 90%, today is 88%, tomorrow is 85…and all of this in 1 or 2 cycles.

This is my powertop output.
Is it normal that “Network interface: wlp8s0 (iwlwifi)” uses 14W?? I have already seen it using 18W. Isn’t it too high?

You should try to discharge it completely. (Battery recalibration to get more accurate readings). Fully drain it so the BMS “learns” when it is really empty…

Most likely it just displays nonsense.
