A system and method for information preservation on a portable electronic device. A signal indicating an energy capacity threshold remaining in the battery of a hand held device may be generated. Then, responsive to such a signal, information may be copied from a volatile memory into a non-volatile memory. The non-volatile memory may be configured to provide instructions for direct execution by a processor, or the non-volatile storage may be attached via an expansion interface. The non-volatile memory may be a removable card. The copy function is typically done in low power modes. Alternatively, the information is only copied provided sufficient battery capacity remains to perform the copy function.
