I'm using a Lenovo T-460S - on suspend the battery drains ~15% per 12 hours. Not sure how to profile this?

How are you measuring power usage during suspend?
Offline
Did you make any progress on this problem? I'm asking because I am facing the same annoyance with a T-470S.
Offline
Suspend needs to use battery to keep the ram state, there might also be other things using battery such as wake-on-lan active for the ethernet port, I would say that some usb devices might also still be receiving power.

Sure, I already deactivated everything in the BIOS like wake-on-lan, but still the battery loses 50% or more overnight when in sleep mode. I need to shut it down completely because of that.
Maybe it is a Thinkpad-only problem, that's why I bumped this thread.
