Simple Linux daemon for suspending OS on some battery charge level. It's a crap, when my Ubuntu at 0%-2% battery level are shutdown without hibernation or without suspending. This small daemon, writted on bash, solve this issue and suspend OS when battery level at 15% (can be configured inside script). Actually at 20% we will recive alert message and at 15% - OS suspending. My laptop can keep all, in suspend mode, about 24 hours on 10% battery charge. Then I can plug battery charger and safty wakeup my laptop and continue working with all tmux sessions and all etc...
# Floor of battery charge percentage for alert message
BAT_SUSPEND_MSG_PERC="20"
# Floor of battery charge percentage for suspend action
BAT_SUSPEND_ACT_PERC="15"sudo wget -O /bin/battery-suspend https://github.com/vladimirok5959/bash-battery-suspend/releases/download/latest/bash-battery-suspend.sh
sudo chmod +x /bin/battery-suspend
linux:~$ battery-suspend
/bin/battery-suspend (start|stop|status)
Status: is not runned
linux:~$ battery-suspend start
Status: runned
Alert perc: 20%
Suspend perc: 15%
linux:~$ battery-suspend status
Status: runned
Alert perc: 20%
Suspend perc: 15%I think it will save nerves for someone... By the way, if you know worked method for Ubuntu for controlling battery charge process (enable/disable battery charging) please write me, will be very grateful. Need to thought how to increase battery life, like this did Asus battery health charging utility and keep battery level always at 60% when you plugget charger for a long time.
