Low Power mode can extend the battery life of Dolby Dimension from 10 hours (all features turned on) to approximately 17 hours.  In this mode, features such as virtualization, head tracking, and LifeMix are unavailable and greyed out in the mobile application.  Trying to enable LifeMix from the headphone in Low Power Mode will result in an error tone being played to remind you that it is unavailable in this state.
