Specialized secondary compartment in a mobile device

A system comprising:

• a memory having computer-readable instructions;
• and
• one or more processors for executing the computer-readable instructions, the computer-readable instructions comprising:
• identifying critical data on a primary storage of a mobile device, wherein the mobile device includes a plurality of internal devices including the primary storage that receive power from the primary battery component during the primary mode;
• backing up the critical data from the primary storage to a secondary storage;
• detecting a charge level of the primary battery component;
• determining that the charge level of the primary battery component is less than a minimum threshold;
• switching the mobile device from a primary mode to a secondary mode, based on the charge level being less than the minimum threshold;
• predicting temporary data that will be accessed during a critical period extending until an expected recharge time of the mobile device;
• and
• adding the temporary data to the critical data, wherein the temporary data is backed up from the primary storage to the secondary storage,
• wherein a secondary battery component only powers fewer than all of the plurality of internal devices including the secondary storage during the secondary mode.

A computer-program product for implementing a secondary compartment of a mobile device, the computer-program product comprising a computer-readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to perform a method comprising:

• identifying critical data on a primary storage of a mobile device, wherein the mobile device includes a plurality of internal devices including the primary storage that receive power from the primary battery component during the primary mode;
• backing up the critical data from the primary storage to a secondary storage;
• detecting a charge level of the primary battery component;
• determining that the charge level of the primary battery component is less than a minimum threshold;
• switching the mobile device from a primary mode to a secondary mode, based on the charge level being less than the minimum threshold;
• predicting temporary data that will be accessed during a critical period extending until an expected recharge time of the mobile device;
• and
• adding the temporary data to the critical data, wherein the temporary data is backed up from the primary storage to the secondary storage,
• wherein a secondary battery component only powers the fewer than all of the plurality of internal devices including the secondary storage during the secondary mode.
