Does there exist any command to check the battery status? (From my laptop, I usually use "acpi")

in /sys/class/power_supply/battery/ you can find all information about the battery in /sys/class/power_supply/usb/ all about usb (power) in /sys/class/power_supply/pm8921-dc all about the charger

battery charge level example: cat /sys/class/power_supply/battery/capacity returns the charge level percentage as show on the screen

upower was dropped in 2.0.1 Taalojärvi. Is there a substitute?

As of 2.0.1 you can query /run/statefs for this which is a wrapper around sysfs.
