I use Accubattery [1] app on my Android,
to (try) improve phone's battery health over time;
I'd like to have a software like that on Linux;
Do you know something similar?
Basically it is a timer that remember user to disconnect
laptop from charger when reached a certain/particular battery charge level,
in order to prevent over-charging;
e.g. when battery charging reaches 80% a notification reminds you to disconnect from charger, in order to prevent over-charging;
the same for the bottom level:
when battery discharging level gets 40%, a notification reminds you to connect the charger, in order to prevent battery-wear;
