Hi noel155
I had never seen that Dell "Sleep Study" before. Looks like a very nice tool. I learned something new today.
I agree with you that it seems that your Intel wireless, your USB controller, and your sound card are causing some of the drain.
Intel Smart Sound, Wake on Voice, & Windows Hello
It appears that "Intel Smart Sound" is causing battery drain, even though it was designed to limit battery drain. I don't much need/want/care-about voice activation of things ... but Microsoft's new "Hello" technology wants us to wake up our computers by talking to them, sign in by putting our faces close to the screen (or swiping our fingerprint)...etc. etc.
Since this is a fairly new technology, it is likely experiencing "growing pains".
If you don't want or need to wake your computer by talking to it, you can very nicely do without the Intel Smart Sound nonsense. By turning that off, it should allow your sound to go to sleep like the rest of your computer, and stop draining your battery while sleeping. (Right now, your sound card is not going to sleep, in case you need it to wake it up when you say "wake up, dumb computer").
Here's a quote from Intel:
Better Battery Life without Compromise
By offloading audio streams to Intel Smart Sound Technology, most systems reduce power consumption and improve battery life while still delivering the great sound you expect. Intel Smart Sound Technology operates whether your device is fully awake or in an InstantGo* state to efficiently handle voice wake events and commands. You don’t need to compromise and turn off your voice software to save battery life.
You can look in the Control Panel's "Programs & Features" and uninstall any "Intel Wake on Voice" program (or app) if you see one. That's the program/app that would have come with a Windows 8/8.1 laptop [in case yours was upgraded to 10]. If you have the recent "Anniversary Update" installed, you might also want to turn off "Windows Hello" (it's facial recognition login feature) -- go to Windows 10 Start Menu > Settings > Accounts > Sign-in Options > Windows Hello ... and turn all the "Hello" settings to "off". Microsoft "Surface" users have been doing this in droves ... it was draining their batteries, too.
Network power settings
There is a setting in Device Manager that tells your computer whether or not it is allowed to turn off your wired/wireless adapters to save power. If you have no need to "wake" your computer remotely (by accessing it from another computer), you should make sure to allow Windows to turn your wired network adapter and your wireless network adapter off ... to save power. You should check the setting for both your wired and wireless network adapters:
1) Right-click the Windows 10 Start Menu icon
2) Select Device Manager
3) Select Network Adapters
4) Right-click the first adapter in the list
.......a) Select Properties
.......b) Select the Power Management tab
.......c) Make sure there is a checkmark in the option-box "Allow the computer to turn off this device to save power"
.......d) Click OK
Repeat step 4 for each adapter shown in the Network adapters list.

General Power Options
You can have a look in your overall Power settings, too. Start > Settings > System > Power & Sleep ... You can make adjustments here to when you want your computer to sleep. Next, you can go to much more detailed settings by clicking on the blue link "Advanced Power Settings". This will take you to the Power Options controls in the Windows 10 Control Panel. To view/alter advanced settings, you'd start by clicking on "Change plan settings", and then on "Change advanced power settings", and then to truly see ALL of the options, click on "Change settings that are currently unavailable". There are many small adjustments you can make there. You'll notice there is an option for USB devices in there (which were singled out in your power report) ... you will likely want to have the "selective suspend" set to save power.
Let us know if none of this helps, or if you have questions.
Also let me know if I wrote clearly enough for you (I could try again).
