An electronic apparatus obtains, from a battery, information about remaining power in the battery; detects a connection with a power supply apparatus, performs control to supply power from the power supply apparatus instead of from the battery, in a case where the connection with the power supply apparatus is detected; and displays a warning related to the remaining power in the battery when the remaining power in the battery is less than or equal to a predetermined threshold, in a case where the electronic apparatus operates using the power from the battery. In a case where the connection with the power supply apparatus is detected, the electronic apparatus displays the warning related to the remaining power in the battery when the remaining power in the battery is less than or equal to a second threshold.

Electronic apparatus, method for controlling the same, and storage medium

An electronic apparatus includes: an acquisition unit configured to acquire information on a remaining time representing a remaining usable time of the electronic apparatus; and a control unit configured to perform control to set any of a plurality of modes including a first mode and a second mode having power consumption of the electronic apparatus that is lower than power consumption of the electronic apparatus in the first mode, wherein the control unit performs processing to provide notification to prompt a user to switch from the first mode to the second mode in a case where the remaining time corresponding to the information acquired by the acquisition unit is less than a threshold and a predetermined condition for switching from the first mode to the second mode is satisfied in the first mode.

Electronic apparatus, control method, and non-transitory computer readable medium

An electronic apparatus according to the present invention sets 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; determines, on a basis of a present power mode, a calculation method for calculating a remaining time which is a remaining usable time of the electronic apparatus; acquires the remaining time from information on a remaining amount of a battery supplying power to the electronic apparatus; switches from the second power mode to the first power mode according to an instruction from a user if a switching condition for switching to the first power mode is satisfied; and does not switch from the second power mode to the first power mode according to the instruction if the switching condition is not satisfied.

An electronic apparatus includes a reception unit configured to receive an instruction from a user; a control unit configured to perform control to set an operating mode of the electronic apparatus to any of a plurality of operating modes including a first mode and a second mode having maximum power consumption lower than maximum power consumption of the first mode according to the instruction from the user, wherein part of a plurality of functions of the electronic apparatus that are available in the first mode are unavailable in the second mode; and a notification unit configured to notify the user of functions unavailable in the second mode among the plurality of functions available in the first mode according to a reception of the instruction to set the operating mode of the electronic apparatus from the user.
