What is the battery voltage? <http://www.grc.nasa.gov/WWW/k-12/airplane/ohms.html> Batteries are rated in mAh, or (3.6 coulombs) units, a unit of charge. An advantage of getting "power" in mA is that you can estimate how long the sensor can run if you know the battery's charge capacity. You can trust the API docs - they are authoritative (or should be). They say "mA", as does every source I've Googled. (You did do a web search prior to asking here, did you not?) For example: <http://books.google.com/books?id=RuN0jb4YASwC&pg=PA895&lpg=PA895&dq=android+measuring+sensor+power&source=bl&ots=u4Jo6Fu_e6&sig=dwDVF6kud38yLjvDG_x0o0wuOjI&hl=en&sa=X&ei=_TBhT7aGF8mq2QWcreSNCA&ved=0CHoQ6AEwCQ#v=onepage&q&f=false> -- Lew -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
