Power Source Hot Swap Mode

A mobile device comprising:

• a processor;
• a removable power source disposed in the mobile device and configured to supply power to the mobile device;
• a backup power source disposed in the mobile device and configured to supply the power to the mobile device when the removable power source has been removed from the mobile device;
• a plurality of components, including a first component and a network component;
• and
• a memory storing instructions that, when executed by the processor, configure the mobile device to:
• detect whether the removable power source has been removed from the mobile device when the mobile device was engaged in a communication session;
• in response to detecting that the removable power source has been removed, enter a hot swap mode for a first time period by deactivating the first component and maintaining the communication session of the mobile device by maintaining, via the backup power source, a powered state of the network component and an application state in the memory of the mobile device;
• after the first time period, enter a suspend mode for a second time period by deactivating the network component and continuing to maintain the application state in the memory for the second time period;
• and
• in the suspend mode, deactivate groups of components of the mobile device in accordance with a rate of discharge of the backup power source.

A tangible computer readable medium having stored thereon computer executable instructions, the instructions comprising:

• detecting whether a removable power source has been removed from the mobile device when the mobile device was engaged in a communication session;
• in response to detecting that the power source has been removed, entering a hot swap mode for a first time period by:
• deactivating a first component of the mobile device, and
• maintaining the communication session of the mobile device by maintaining, via a backup power source in the mobile device, a powered state of a network component of the mobile device and an application state of the mobile device;
• during the first time period:
• transmitting one of a shutdown notification and a low memory notification, and in response to transmitting one of the shutdown notification and the low memory notification, persisting user data from a first memory to a second memory.
