I am trying to collect power usage statistics for the Android G1 Phone. I am interested in knowing the values of Voltage and Current, and then able to collect statistics as reported here http://dl.google.com/io/2009/pres/W_0300_CodingforLife-BatteryLifeThatIs.pdf
I am able to get the value of Battery voltage through registering for an intent receiver to receive the Broadcast for ACTION_BATTERY_CHANGED. But the problem is that Android does not expose the value of current through this SDK interface. One way I tried is via sysfs interface, where I can view the battery current value from adb shell, using the following command $cat /sys/class/power_supply/battery/batt_current 449 But that too works only if the phone is connected via USB interface. If I disconnect the phone, I see the value of batt_current as '0'. I am not sure why the value of current reported is zero. It should be more than zero, right? Any suggestion / pointers for getting battery current value? Also please correct me if I am wrong. -- unsubscribe: android-kernel+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-kernel
