[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. Much appreciated, Sean On Nov 10, 3:54 pm, Dianne Hackborn hack...@android.com wrote: That is just the precision the Droid battery reports. Note that the Droid's battery measurement is actually much more accurate than the G1 or myTouch.

For example 70%, 60% etc. Any apps or widgets also can only see this as well. Is this a bug, what happened to the detailed stats? -- You received this message because you are subscribed to the Google Groups Android Developers group.
