Mine is usually wifi, then screen.

Right now wifi is at 8%, and I used it for maybe 15 minutes this morning, that's it.

Motorola Moto X Play, Android 6.0.1, for what it's worth.

As far as I know, Marshmallow has a battery drain issue, but Motorola (now Lenovo) does not seem to be interested in updating their software anymore.
