The night mode feature is useful in achieving the ideals of reducing energy usage and prolonging the life of the device. To further the pursuit of these ideals, providing operating modes the user can customize would be nice, possibly combined with a motion based sensor similar to how Nest Thermostats manage a home’s climate.
Allow the user to select from a set of default operating modes (e.g. home, away) or create custom ones (party, vacation) to drive the unit. Each mode has its own settings like, which apps to run, network configuration, the location of use for this mode, etc).
With the assistance of motion sensor, the operating modes could be enhanced to further reduce energy usage and prolong the device. See, Motion Sensor
