6 . The electronic apparatus according to claim 5 , wherein

the power from a battery that is a power supply of the electronic apparatus, is supplied to the external apparatus in a case where the power controller is supplying power to the external apparatus, and

the battery is charged by power from the external apparatus in a case where the power controller is receiving power from the external apparatus.

7 . The electronic apparatus according to claim 1 , further comprising an image pickup element to capture an image,

wherein

the control unit controls the display to display the predetermined icon in at least one of: a case where a live view image is displayed to prepare for image capturing; a case where an image acquired by image capturing is reproduced; and a case where a screen to perform setting for image capturing is displayed.

8 . The electronic apparatus according to claim 1 , further comprising a battery, wherein

the predetermined screen includes information on a charging state of the battery.

9 . The electronic apparatus according to claim 1 , wherein

the predetermined screen includes information on a communication state between the electronic apparatus and the external apparatus.

10 . The electronic apparatus according to claim 1 , wherein

the predetermined touch operation is one of: one touch, press and hold, swipe, double tap, and Pinch-Out.

11 . The electronic apparatus according to claim 1 , wherein

the control unit performs a control such that a screen of an application of the electronic apparatus is displayed with the predetermined icon on the display in a case where the application is started up, and switches a display of the display from the screen of the application to the predetermined screen in accordance with the predetermined touch operation detected by the detection unit in a state where the screen of the application of the electronic apparatus is displayed with the predetermined icon on the display.

12 . The electronic apparatus according to claim 11 , wherein

in response to an instruction of end of the display of the predetermined screen, the control unit switches a display on the display from the predetermined screen to the screen of the application.

13 . The electronic apparatus according to claim 1 , wherein

the at least one memory and the at least one processor further function as a power controller configured to supply and receive power to/from the external apparatus connected to the electronic apparatus based on a Universal Serial Bus power delivery (USB PD) standard, and

the power controller 1) supplies power to the external apparatus in a case where the electronic apparatus is a source of the USB PD, and 2) receives power from the external apparatus in a case where the electronic apparatus is a sink of the USB PD.

14 . The electronic apparatus according to claim 13 , further comprising a connector conforming to USB Type-C, wherein

the electronic apparatus is connected to the external apparatus via a cable connected to the connector.

15 . A control method for an electronic apparatus that is capable of supplying and receiving power to and from a connected external apparatus, the method comprising:

displaying a predetermined icon indicating information regarding power in the electronic apparatus on a display;

detecting a predetermined touch operation on the predetermined icon displayed on the display;

in a case where the predetermined touch operation on the predetermined icon is detected in the detecting, performing a control such that a predetermined screen is displayed on the display together with the predetermined icon, the predetermined screen including information on a direction of power flow between the electronic apparatus and the external apparatus connected to the electronic apparatus.

16 . A non-transitory computer readable medium that stores a program,

wherein
