I have TLP installed and enabled (through systemd). In its configuration, I set batter thresholds to 75%/80%. But seems it does not work. When plugged, my battery always gets fully charged, at least that is what indicated on the system tray. I have checked the status of TLP via systemctrl, it is active and the status info also says battery thresholds were applied. But it seems it is not effective. Why? I will appreciate any help to diagnose the problem. If more information is needed, please let me know.
