What's your code like after you added battery monitoring? – ott-- Nov 26 '12 at 21:39

If you want to know how to detect device is charging, check this http://stackoverflow.com/questions/13186203/how-to-know-when-the-device-is-charging/13186288#13186288. You cant predict the exact battery lifetime. – iDev Nov 26 '12 at 23:31

In short, you can't. At least not with any accuracy.
Or, really, you can't unless the user is going to continue doing exactly what they are doing right now without any changes in network, signal strength, ambient light, etc... As well, receiving push notifications and/or taking phone calls can impact battery life. So can media playback, including -- even -- the encoding format used within the media.
