Show the remaining battery percentage below which the battery will be charged.\u00a0 The default is 0, which means the battery will always charge when on AC power.<\/p>\n
$ cat \/sys\/class\/power_supply\/BAT1\/charge_start_threshold
\n0<\/p>\n
Change it to 5% so the battery won’t charge unless it has less than 5% of a full charge remaining :
\n$ sudo sh -c “echo 5 > \/sys\/class\/power_supply\/BAT1\/charge_start_threshold”<\/p>\n
Show the remaining battery percentage above which the battery will not be charged.\u00a0 The default is 100, which means the battery will be charged until completely full.
\n$ cat \/sys\/class\/power_supply\/BAT1\/charge_stop_threshold
\n100<\/p>\n
Change it to 95%:
\n$ sudo sh -c “echo 95 > \/sys\/class\/power_supply\/BAT1\/charge_stop_threshold”
\nCheck what the battery is doing (returns discharging or charging):
\n$ cat \/sys\/class\/power_supply\/BAT1\/status<\/p>\n
