Mobile systems with seamless transition by activating second subsystem to continue operation of application executed by first subsystem as it enters sleep mode

At least one non-transitory computer-readable medium comprising one or more instructions that when executed on a computing device cause the computing device to:

• store in a second storage device of a second subsystem at least a subset of data being processed from a first storage device of a first subsystem to render content to a user while the first subsystem is in a relatively higher power normal operating state;
• automatically process the at least subset of the data from the second storage device to continue rendering the content to the user when the first subsystem exits the relatively higher power normal operating state and enters a relatively lower power different operating state;
• enter the first subsystem back to the relatively higher power normal operating state;
• store in the second storage device of the second subsystem at least a subset of additional data from the first storage device when the first subsystem is back in the relatively higher power normal operating state;
• exit the first subsystem from the relatively higher power normal operating state to re-enter the relatively lower power different operating state when the at least subset of the additional data is stored in the second storage device;
• and
• automatically process the at least subset of the additional data from the second storage device to continue rendering the content.
