Method and apparatus for hibernation operation in multiple operating system environments

An electronic device comprising:

• a rechargeable battery;
• a first memory configured to store a first operating system used in a normal power state and a second operating system used in a low power state, the first memory being non-volatile memory;
• a second memory, the second memory being volatile memory;
• and
• a processor,
• wherein the processor is configured to:
• identify, while executing the first operation system, remaining capacity of the rechargeable battery is less than reference capacity,
• in response to identifying that the remaining capacity is less than the reference capacity, store data that is stored in the second memory while executing the first operating system to the first memory and switch the executing first operating system to a second operating system, and
• in response to identifying that the remaining capacity is greater than or equal to another reference capacity while executing the second operating system, restore a state of the first operating system as a state immediately before the switching to the second operating system, by switching the second operating system to the first operating system and executing the first operating system based on the data stored in the first memory.
