I have a Dell XPS 13 9360 which is ~3,5 years old. I have Manjaro XFCE along Windows 10 on it, however I rarely use Windows, but I need it occasionally.
Battery capacity isn’t what it has been, although I know a lot of it can be explained taken the age into account. However, I’m a little suspicious that Manjaro has some influence or I have forgotten to configure something I’m not aware of, as I get roughly the same uptime when I use Windows. I’d expect to have a longer uptime when using Manjaro, but maybe I’m wrong?
sudo tlp-stat -b
--- TLP 1.3.1 -------------------------------------------- +++ Battery Features: Charge Thresholds and Recalibrate natacpi = inactive (laptop not supported) tpacpi-bat = inactive (laptop not supported) tp-smapi = inactive (laptop not supported) +++ Battery Status: BAT0 /sys/class/power_supply/BAT0/manufacturer = SMP /sys/class/power_supply/BAT0/model_name = DELL TP1GT61 /sys/class/power_supply/BAT0/cycle_count = (not supported) /sys/class/power_supply/BAT0/charge_full_design = 7894 [mAh] /sys/class/power_supply/BAT0/charge_full = 3562 [mAh] /sys/class/power_supply/BAT0/charge_now = 3562 [mAh] /sys/class/power_supply/BAT0/current_now = 1 [mA] /sys/class/power_supply/BAT0/status = Full Charge = 100.0 [%] Capacity = 45.1 [%]
It shows that my capacity is roughly halfed, but can it be a mistake that it just ‘thinks’ that it is full when it reaches 3562 mAh and therefore stops charging due to some configuration issues?
I thought maybe calibration could be done in some way or another.
Hope someone has 2 cents to spare on this one.
Thanks in advance .
