## Abstract

An electronic device for displaying information related to a stylus pen is provided. The electronic device includes a wireless communication link, which is based on a short-range wireless communication protocol, with a stylus pen inserted into an inner space of a housing, detects that the stylus pen is detached from the housing, receives a signal including information about a battery state of the stylus pen from the stylus pen through the short-range wireless communication protocol, and displays a first graphical user interface (GUI) indicating the battery state, based at least on the information about the battery state.

## Claims

### Claim 1

a display viewable through a portion of the housing;
a wireless communication circuit disposed within the housing;
at least one processor disposed within the housing and operatively connected with the display and the wireless communication circuit; and
a memory disposed within the housing and operatively connected with the at least one processor,
wherein the memory stores instructions that, when executed, configure the at least one processor to:
establish a wireless communication link, which is based on a short-range wireless communication protocol, with a stylus pen inserted into an inner space of the housing, through the wireless communication circuit,
receive a signal including information about a battery state of the stylus pen from the stylus pen, through the wireless communication circuit and the short-range wireless communication protocol,
measure a status of the established wireless communication link,
detect that the stylus pen is detached from the housing,
display a graphical user interface (GUI) including a first GUI indicating the battery state and a second GUI indicating the status of the wireless communication link through the display, based at least on the information about the battery state and the measured status of the wireless communication link, and
release a display of the first GUI and the second GUI through the display in response to detecting that the stylus pen is inserted into the inner space of the housing.

### Claim 2 (depends on 1)

The electronic device of claim 1, wherein the short-range wireless communication protocol is based on a Bluetooth (BT) standard or a Bluetooth low energy (BLE) standard defined by a Bluetooth special interest group (SIG).

### Claim 3 (depends on 1)

The electronic device of claim 1, wherein the instructions, when executed, further configure the at least one processor to:
control the first GUI, based at least on at least a portion of the information about the battery state, such the first GUI indicates the battery state for each level through the display.

### Claim 4 (depends on 1)

The electronic device of claim 1, wherein the instructions, when executed, further configure the at least one processor to:
detect that the wireless communication link is released;
provide an effect that the second GUI is disappearing, through the display;
re-establish the wireless communication link, through the wireless communication circuit;
provide an effect that the first GUI is flickering, through the display, while the wireless communication link is re-established; and
provide the second GUI through the display when the wireless communication link is re-established.

### Claim 5 (depends on 1)

The electronic device of claim 1, wherein the instructions, when executed, further configure the at least one processor to:
receive a signal including information about a color of the stylus pen from the stylus pen, through the wireless communication circuit and the short-range wireless communication protocol; and
display a third GUI having the color of the stylus pen through the display, based at least on the information about the color.

### Claim 6 (depends on 5)

The electronic device of claim 5, wherein the instructions, when executed, further configure the at least one processor to:
display the third GUI in a state where a screen of the display is turned off.

### Claim 7

A method of an electronic device, the method comprising:
establishing a wireless communication link, which is based on a short-range wireless communication protocol, with a stylus pen inserted into an inner space of the electronic device;
receiving a signal including information about a battery state of the stylus pen from the stylus pen, through the short-range wireless communication protocol;
measuring a status of the established wireless communication link;
detecting that the stylus pen is detached from a housing of the electronic device;
displaying a graphical user interface (GUI) including a first GUI indicating the battery state and a second GUI indicating the status of the wireless communication link, based at least on the information about the battery state and the measured status of the wireless communication link; and
releasing a display of the first GUI and the second GUI in response to detecting that the stylus pen is inserted into the inner space of the electronic device.

### Claim 8 (depends on 7)

The method of claim 7, wherein the displaying of the first GUI includes:
controlling the first GUI, based at least on at least a portion of the information about the battery state, such the first GUI indicates the battery state for each level.

### Claim 9 (depends on 7)

The method of claim 7, further comprising:
detecting that the wireless communication link is released;
providing an effect that the second GUI is disappearing;
re-establishing the wireless communication link;
providing an effect that the first GUI is flickering, while the wireless communication link is re-established; and
