-It reads the **/sys/class/power_supply/axp20x-battery/uevent** file.
+Initially it read **/sys/class/power_supply/axp20x-battery/uevent** file and computed a percentage from the data extracted. 
+Currently **upower** is used to get the percentage from **/org/freedesktop/UPower/devices/battery_axp20x_battery**
+
+Although old way is still present as a fallback option, if the device doesn´t have upower or running it doesnt give a proper result,
+percentage display will be built from **/sys/class/power_supply/axp20x-battery/uevent** like below.
