Solve : Significant Battery Drain in 'Sleep' Mode?

1.	Solve : Significant Battery Drain in 'Sleep' Mode?
Answer» My Surface Pro 4 (Win 10-64) is set to "Sleep" when the lid is closed. I've noticed it loses a lot of JUICE when the lid is closed and it's unplugged. Attached are the results of: powercfg /batteryreport powercfg -energy powercfg -sleepstate So obviously what I (and the Control Panel) call "Sleep", Windows' diagnostics calls "Connected Standby". I attached the Battery Report and Sleep State report so you could see the drainage today, while it sat supposedly idle with the lid closed (it's set to go to "Sleep" but not "Hibernate") on battery power. I attached the "Energy" report because I have no idea if that provides any helpful info. Basically, is there a way - other than Hibernation - for this darn thing to use less power? I've seen on the Google there's supposedly a way to turn off WIFI in Sleep, but the Internet's screen shots don't match my screen!

Any advice, tips, suggestions, wouldbe appreciated!
