I am wondering about a possible battery draining scenario?
I notice that if the app is closed (home button pressed or move to another app) there is not indication it is still active (some apps show a red bar allong the top of the screen to warn that an app is still churning madly in the background).
Thus the Mooshimeter still shows high activity when I think I have shut it down. Oven closing the cover of an iPad allows it to continue. Only when actually removing the app from the active list actuall breaks the data stream.
Not sure how much drain there is in this mode? But I would imagine forgetting to do a complete shutdown would also put a drain on the display device.
Sorry, just musing about this without taking any readings. (Can the mooshimeter be used to measure its own current draw?)
