regarding wazapp and battery idle consumption - latest official version nearly solved the issue... now only once in a while idle consumption goes up... I'm using Battery Usage app, and I notice that, when consumption goes up, it is due to "Audio Playback" - out of nowhere it goes on the top postions of the "Top energy consumers" list in Battery usage app. (usage is reported as 100% background)… then I quit Wazapp, start it again, briefly plug N9 to charger, just to reset the Battery Usage app data, and the idle consumption goes down to the usual level… hope it helps… and hope this old "Audio playback" Wazapp issue is to be solved soon…
