Agree with the RIDICULOUS battery drain...Every day I am losing a ton of battery with the machine in connected standby.

Attached is screenshot. I turned off BT and disabled Cortana two days ago and thought that would help. NOPE.

2 days ago I put it in airplane mode and of course there was ZERO battery drain. So I guess that's going to have to happen on Windows 10? I mean, come on. 8.1 NEVER drained this fast.

In the first case it appears you have a Windows Phone with a sync issue. In the second case something is connected by USB.

Both need some detective work.
