at least one memory storing a program which, when executed by the at least one processor, causes the electronic apparatus to function as:
a setting unit configured to set a power mode of the electronic apparatus from among a plurality of power modes including a first power mode and a second power mode having maximum power consumption lower than maximum power consumption of the first power mode;
a determination unit configured to determine, on a basis of a present power mode set by the setting unit, a calculation method for calculating a remaining time which is a remaining usable time of the electronic apparatus; and
an acquisition unit configured to acquire the remaining time of the electronic apparatus from information on a remaining amount of a battery acquired from the battery supplying power to the electronic apparatus by using the calculation method determined by the determination unit, wherein
the setting unit performs switching of the power mode from the second power mode to the first power mode according to an instruction from a user in a case where a switching condition for switching to the first power mode is satisfied, and does not perform the switching of the power mode from the second power mode to the first power mode according to the instruction in a case where the switching condition for switching to the first power mode is not satisfied.
