Sony posted somewhere that Stamina is not on Marshmallow because it's redundant as Doze does the same thing.

Here is a snip from Xperia Blog:

The Marshmallow version of Android has its own smart solution for managing power consumption (Doze and App Standby). These functions are integrated directly into Android 6.0, which made Stamina mode redundant. In other words, Stamina mode was removed from M.
