Hi,
the BatteryService is working like this:
cd /sys/class/power_supply
for each dir:
if have a file named type:
if type == Battery
read capicty ...etc
if type == AC
read online
if type == USB
read online
If you mean it not updated on unplug & plug charger, you should first check
the type of your power_supply driver.
