2015 MBPR Running 10.11 draining battery overnight

Ever since I upgraded to El Capitan my MBPR has been depleting the battery to about 2 percent until it goes into save mode and I'm not quite sure what's causing it. I've noticed I'll hear the fans kick in to full gear a short while after it's still closed for a few minutes then stop, and when I pull it out of my briefcase it'll be fairly warm (quite concerning, honestly).

Under energy saver I have it set to display off after 5 minutes, hard disks to sleep (though it doesn't matter since they're all flash), slightly dim display, and Power Nap is disabled.

Programs open/running when I plugged in the macbook to charge this morning:

Adobe CC Ps Lr Ai Id Acrobat

Safari

Messages

Outlook '11

Spotify

Mail

AU Lab

Dropbox

X-Rite Color Munki Display

Wacom tablet driver

I think I had left Soundflower Bed running as well but it crashes occasionally and wasn't running when the computer powered back up.

Battery was probably 70% when I went to sleep last night.

MacBook Pro with Retina display, OS X El Capitan (10.11), 15" Mid 2015 2.5GHz i7 16GB AMD R9

Test after each of the following steps that you haven’t already tried:

Step 1

Take all the applicable steps suggested in this support article. That's the starting point for any further effort to solve the problem. Skipping any of those steps may mean that the problem won't be solved.

Note that, as stated in the article, the computer will not sleep if some sharing services are enabled. From the menu bar, select

 ▹ System Preferences... ▹ Sharing

Turn off all sharing services.

Step 2

If iTunes Music Sharing or Home Sharing is enabled, disable it or quit iTunes. Do the same with any third-party applications that have a similar feature.

Step 3

Select

 ▹ System Preferences... ▹ Accessibility ▹ Speakable Items: Off

Step 4

Select

 ▹ System Preferences... ▹ Bluetooth ▹ Advanced...

and uncheck both boxes marked

Open Bluetooth Setup Assistant at startup if...

Step 5

Reset the printing system.

Step 6

Back up all data.

Triple-click the line below on this page to select it, then copy the text to the Clipboard by pressing the key combination command-C:

/var/vm

In the Finder, select

Go ▹ Go to Folder...

from the menu bar and paste into the box that opens by pressing command-V. You may not see what you pasted because a line break is included. Press return.

A folder named "vm" should open. Inside it, there may be a file named "sleepimage". Move that file, and only that one, to the Trash, but don't empty yet. You'll be prompted for your password. Close the folder window.

Restart the computer and empty the Trash.

Checked activity monitor and made sure to shut off anything preventing sleep, still woke up to a dead macbook this morning, so I've reset the SMC and NVRAM, guess I'll find out if that helped tomorrow.
