Device operation in a reduced operational mode

A method, comprising:

• receiving a signal to transition a mobile computing device from a full operational mode to a reduced operational mode;
• reducing a radiation output of one or more components of the mobile computing device;
• determining that the radiation output of the one or more components satisfies a threshold radiation level associated with the reduced operational mode;
• presenting a message after the radiation output is determined to satisfy the threshold radiation level, the message indicating that the mobile computing device is operating in the reduced operational mode;
• and
• resuming the full operational mode by restoring a non-reduced radiation output of the one or more components that exceeds the threshold radiation level.

One or more non-transitory computer-readable media storing computer-executable instructions that, when executed on one or more processors, performs acts comprising:

• monitoring data to determine whether a mobile computing device is within a restricted-use zone;
• presenting a list of components of the mobile computing device that are eligible for a reduced operational mode after the data initially indicates that the mobile computing device is within the restricted-use zone;
• receiving a user selection of one or more components presented in the list of components;
• operating the one or more components of the mobile computing device in the reduced operation mode while the data continues to indicate that the mobile computing device is within the restricted-use zone;
• and
• operating the one or more components in a full operation mode after the data indicates that the mobile computing device is no longer-within the restricted-use zone.

A method, comprising:

• receiving a radio signal from a beacon, that instructs a mobile computing device to switch from a full operational mode to a reduced operational mode associated with a threshold power level;
• in response to receipt of the radio signal from the beacon, presenting a list of components eligible for a reduction in power to achieve the reduced operational mode;
• receiving a selection of one or more components from the list of components presented;
• comparing an anticipated power level after reduction of power of the one or more components to the threshold power level based on empirical values of the one or more components stored in an index file;
• determining that the anticipated power level satisfies the threshold power level based at least in part on the comparing;
• reducing power to the one or more components to initiate the reduced operational mode;
• and
• restricting use of the one or more components above the threshold power level during operation in the reduced operational mode.
