Huge battery drain - Is it my battery pack or is it 950?

[soloist_huaxin]

I left my 950 connected to a full charge of Anker E3 battery back(3.7v 10000mah) overnight, and 10 hours later the battery pack has less than 50% power left, which indicates that the phone used almost TWICE its battery capacity when I'm not using it?! How is this possible? I mean, even left unplugged, the phone didn't use much battery at all...
