[Q] reset battery status (as device has no battery)
let me say one thing first: i don't want to discuss if resetting the battery status database helps in any way to prolong the battery life of a phone or such, i have a different issue with the battery management under android:
i have taken the guts out of an AN1 Smart Watch and used them as a tiny touch panel in an appliance. in order for it to run without a battery i have connected a little voltage regulator that converts DC12V to DC4V and feeds it right into the + and - Pin of the battery contacts. This way i can start and run the device wihtout any battery in it, which otherwise is not possible when trying to run it from USB power, even though i haven't seen the device pull more than about 300mA at most.
the device turns on and runs just fine, but what's bothering me is, that the battery charge indicator is counting downwards even though the voltage stays constant and obviously notthing really is being discharged since there is no battery.
i don't want to re-insert the battery and run from usb power as the battery will certainly fail within only a few years and i would really like the whole thing to run a bit longer than that.
is there any way i can re-set the battery countdown or disable it entirely? if disabling the simulated drain is not possible, resetting it should be possible while the device is running. i don't want to reboot the thing every day just to reset the battery stats or anything like that.
hope somebody can help me out here.
i currently have the AN1 running to see what's going to happen when it reaches 0% ..
