I've also taken the update without issue.
Some things I've done are as follows:
Google settings - turn off both options listed in android device manager. Turn off location reporting and location history under Google location reporting. I leave mode set to high accuracy for other apps.
Moto settings - I leave Moto display active but turn off Moto actions. I don't need motion and those sensors eat battery.
Here's what my drain looks like right now.
