Hi Mark! I want to display Batter level stats in my app as shown in the following link: http://itunes.apple.com/us/app/app-genie/id352781306?mt=8 Wonder how can i access batter voltage/power information at runtime?

Here is my interpretation: -- Precision refers to the fineness of detail. Many Android devices report at 1% precision, but the DROID reports at 10% precision. -- Accuracy refers to how well the reported values reflect reality. > If I am mistaken, which I hope I am, how would we go > about accessing the finer granularity that is needed when developing > battery applications on the Droid? As far as I know, you can't. As Ms. Hackborn said, "[10%] is just the precision the Droid battery reports". > I have no problem getting single > digit precision with other handsets only the Droid produces the > strange '10's increments' only. That's the way Motorola elected to implement the battery level information. The SDK does not mandate a minimum level of precision, so device manufacturers can report 1%, 10%, 3.14%, or whatever floats their boats. Applications (particularly paid ones) should not be relying upon some minimum level of precision, just as they should not be relying on certain LED colors or the availability of a physical CAMERA button. If you have more detailed questions on Motorola devices, I recommend asking Motorola the questions, since they have developer support boards: http://developer.motorola.com -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Android Development Wiki: http://wiki.andmob.org -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: Android 2.0 battery level
Dianne, Is this to say that the Droid has the capability to report higher precision values given the nature of the hardware BUT there is no way to access it? If I am mistaken, which I hope I am, how would we go about accessing the finer granularity that is needed when developing battery applications on the Droid? I have no problem getting single digit precision with other handsets only the Droid produces the strange '10's increments' only.
