Patent attributes
An electronic apparatus is provided with a processing unit that has a first operation mode in which an operation is enabled using only external power from a feeding device and a second operation mode in which the operation is enabled by feeding from a battery in addition to the external power from the feeding device. When the remaining capacity of the battery is sufficient, the processing unit executes an apparatus operation in the second operation mode. However, when the remaining capacity of the battery decreases, the processing unit changes an operation mode to the first operation mode and executes charging of the battery while continuously executing the apparatus operation.
