I'm disappointed to see that it will take Android N for the Doze feature to be practical [0]. As it currently stands, Doze only activates when the device is stationary. My phone never leaves my pocket, since I'm paranoid about setting it down, so the gyrometer being engaged is enough to prevent Doze from triggering.

You sleep with your phone in your pocket? That's really the thing doze is great at. If you forget to charge your phone, you wake up with still decent amount of battery left. Or for tablets sitting around on tables/desks.
I do however, sit/stand at my desk for 8-9 hours a day and maybe pull the phone out less than once an hour. I would like the phone to be in Doze mode when it's in my pocket, rather than forcing me to have to put it on my desk. As I said, I don't like leaving it unattended, even if it's simply to step away for a few minutes to the watercooler.
