[Moto X Q&A] scorpion667:
Disclaimer: Use your own discretion. I am not responsible if you break your phone. Feel free to suggest more and I will add them to the list after I test it!

I have tested the following settings for 5 days with no adverse effects to Active Notifications, Touchless Controls, Google now and the standard phone features like calls and sms. If you encounter any issues please try to identify which service is causing it and I will modify the description of said service to reflect that. My battery life is still pretty good as shown all the way below so no issues there either.

Legend:

Lime = No issues or known side effects, tested stable

Sea Green = Caution, some side effects [which I list for each] but no impact on stability

Red = Breaks functionality for certain phone features [which I list for each] I don't recommend freezing these

Orange = Just Google apps
