The disclosure relates to a power control method and an electronic device for performing the same.
A ship mode may turn off all blocks (or a module) in an integrated circuit (IC) of an electronic device and may remove a leakage current of the electronic device by disconnecting a switch between a battery of the electronic device and an internal power system of the electronic device.
Since a leakage current does not occur in the ship mode, the electronic device may minimize and/or reduce the power consumed by an interface power management IC (IF PMIC), a charging module (or a charger), and/or a system. In the electronic device in the ship mode, wired or wireless charging may need to be recognized, a specific signal may need to be applied, or a power key of the electronic device may need to be pressed to cancel the ship mode.
When releasing an electronic device, a forced ship mode may be applied. The forced ship mode may refer to setting the electronic device to the ship mode using a ship mode command through an inter-integrated circuit (I2C) or other channels regardless of a voltage level of a battery.
A leakage current may be minimized/reduced from a time point when the electronic device enters the forced ship mode and a time taken for reaching battery overdischarge may significantly increase compared to a case in which the ship mode is not applied.
After an electronic device is manufactured, by setting the electronic device to enter a forced ship mode through a command using an inter-integrated circuit I2C or other channels before releasing the electronic device, a leakage current of the electronic device may be minimized/reduced and a time to battery overdischarge may increase, thereby a risk of battery swelling may decrease even if the electronic device is kept for a long period in an inbox state. However, when a user keeps an electronic device for a long time after turning off the power of the electronic device in use, a leakage current of the electronic device may not be minimized/reduced and there is a risk of battery overdischarge.
In the case of an electronic device in use by a user, various Android application packages (APKs) and programs may be installed in the electronic device depending on a user's use condition, and depending on a use condition of a power off sequence, for example, depending on a system operation or an APK operation when turning off the power, a time to completely turn off the power of the electronic device may increase. In the case of the electronic device in use, since a time of a power off sequence operation may vary depending on a use condition, the power off operation may not be normally terminated and a sudden power off event may occur when a forced ship mode for entering the ship mode after a predetermined time period has elapsed is applied. When entering the ship mode before the completion of the power off operation, malfunction of an integrated circuit (IC) or damage may be caused in the electronic device.
In the case of a structure in which a system and a battery are separated from each other and separately controlled, a fuel gauge IC may not be provided with power directly from the battery, and in the case of a structure in which the power is provided by a system end, the fuel gauge IC may be reset if the electronic device enters the ship mode whenever a user turns off the power of the electronic device. Since the fuel gauge, which has been reset when canceling the ship mode of the electronic device, estimates an initial state of charge (SOC) based on a terminal battery voltage, a problem that an SOC displayed through a user interface (UI) before and after turning off the power of the electronic device changes may occur.
Embodiments of the disclosure provide a power control method of monitoring a voltage of a battery after a power-off operation and setting an electronic device to a ship mode when the voltage of the battery after turning off the power is less than or equal to a voltage to enter the ship mode and an electronic device for performing the same.
Embodiments of the disclosure provide a power control method of entering a ship mode depending on a voltage level of a battery after a user turns off the power of an electronic device and neglects the electronic device for a long period and an electronic method for performing the same.
Embodiments of the disclosure provide a power control method of storing power gauge data and loading stored power gauge data when canceling a ship mode and an electronic device for performing the same.
Embodiments of the disclosure provide a power control method of setting an electronic device to a ship mode when a set time period has elapsed after a power-off operation and an electronic device for performing the same.

A power control method according to various example embodiments may include: identifying a signal to turn off power of an electronic device, turning off the power of the electronic device, counting a set first time period from when the signal to turn off the power is identified, and setting the electronic device to a ship mode to prevent and/or reduce discharge of a battery due to a leakage current.
According to a power control method and an electronic device for performing the same in various example embodiments, an electronic device may enter a ship mode depending on a use condition of the electronic device of a user when turning off the power of the electronic device.
According to a power control method and an electronic device for performing the same in various example embodiments, the stability of a battery and an electronic may be improved by causing the electronic device to enter the ship mode depending on a use condition of the electronic device of a user and the ship mode may be canceled without resetting fuel gauge data by storing the fuel gauge data before entering the ship mode.

The power management module 188 may determine, using, for example, the charging circuit 210, the power adjuster 220, or the power gauge 230, charging state information (e.g., lifetime, over voltage, low voltage, over current, over charge, over discharge, overheat, short, or swelling) related to the charging of the battery 189 based at least in part on the measured use state information about the battery 189. The power management module 188 may determine whether the state of the battery 189 is normal or abnormal based at least in part on the determined charging state information.

For example, a voltage of the power required for the AP 120-1 may vary depending on an internal configuration of the AP 120-1 and/or an operation state of the AP 120-1, and the AP PMIC 120-2 may supply the power required for the internal configuration of the AP 120-1 by converting the input power.
According to various embodiments, the power management module 188 may include a charging circuit 260, the power gauge 230, a switch 250, a power control module (e.g., including power control circuitry) 270, an interface module (e.g., including interface circuitry) 275, and a microcontroller unit (MCU) (e.g., including various control and/or processing circuitry) 290.
For example, the charging circuit 260 may charge the battery 189 using power input from the outside or may supply power to the processor 120. An operation of the charging circuit 260 may be controlled by the power control module 270. For example, based on the control of the power control module 270, power may be supplied to the battery 189 and/or the processor 120 by converting external power input to the charging circuit 260. For example, the charging circuit 260 may include a pulse width modulation driver (PWM DRV) 261 and a buck converter 262. For example, the PWM DRV 261 may be operated by a control signal provided by the power control module 270. The PWM DRV 261 may be operated based on the control signal and may supply the external power input from an adapter 300 (e.g., a TA of
For example, the switch 250 may form a path to supply power from the battery 189 to components in the electronic device 101. For example, when the switch 250 is in an on state, power may be supplied to the processor 120 from the battery 189.

The example of
For example, when a voltage magnitude to be supplied to a component in the electronic device 101 is different from a voltage magnitude output from the power management module 188 and/or the battery 189, the electronic device 101 may include a conversion module configured to convert power output from the power management module 188 and/or the battery 189.
For example, the processor 120 may include various processing circuitry and/or multiple processors. For example, as used herein, including the claims, the term “processor” may include various processing circuitry, including at least one processor, wherein one or more of at least one processor, individually and/or collectively in a distributed manner, may be configured to perform various functions described herein. As used herein, when “a processor”, “at least one processor”, and “one or more processors” are described as being configured to perform numerous functions, these terms cover situations, for example and without limitation, in which one processor performs some of recited functions and another processor(s) performs other of recited functions, and also situations in which a single processor may perform all recited functions. Additionally, the at least one processor may include a combination of processors performing various of the recited/disclosed functions, e.g., in a distributed manner. At least one processor may execute program instructions to achieve or perform various functions. The processor 120 may, for example, receive a user input to turn off the power of the electronic device 101. The processor 120 may receive a user input A to turn off the power of the electronic device 101 through a power key input of the electronic device 101 or an interface of a display module (e.g., the display module 160 of
For example, the processor 120 may identify a voltage of the battery 189 when receiving the user input A. For example, the power control module 270 may identify a voltage of the battery 189. When receiving a user input, the processor 120 may identify a voltage of the battery 189 from the power control module 270.
For example, the processor 120 may set a reference voltage to enter a ship mode. For example, when receiving the user input A to turn off the power of the electronic device 101 and a set margin voltage, the processor 120 may determine a reference voltage based on the identified voltage of the battery 189.
According to an embodiment, when a maximum charging voltage of the battery 189 is 4.4 V and a cut-off voltage of the PCM 240 is 2.5 V, the electronic device 101 may determine a reference voltage from 20 voltage levels in the unit of 0.1 V within a range between the maximum charging voltage and the cut-off voltage. For example, when the identified voltage of the battery 189 is 4.0 V and the set margin voltage is 300 mV, the electronic device 101 may determine the reference voltage to be 3.7 V. In another example, when the identified voltage of the battery 189 is 3.94 V and the set margin voltage is 300 mV, the electronic device 101 may determine the reference voltage to be 3.6 V, which is a voltage level less than a voltage obtained by subtracting the margin voltage from the voltage of the battery 189.
According to various embodiments, the processor 120 may determine the reference voltage such that the reference voltage is greater than or equal to the cut-off voltage. As described above, the processor 120 may determine the reference voltage depending on a voltage magnitude obtained by subtracting a margin voltage from a voltage of the battery 189 when receiving a user input.
For example, the processor 120 may set a margin voltage by considering a cut-off voltage of the battery 189 and a voltage range of the battery 189 when the electronic device 101 is in a normal operation. For example, when the voltage range of the battery 189 when the electronic device 101 is in a normal operation is greater than or equal to 3.3 V and less than or equal to 4.4 V and the cut-off voltage of the battery 189 is 2.5 V, the processor 120 may set a margin voltage to be less than or equal to 0.8 V, which is a voltage magnitude obtained by subtracting a cut-off voltage of the battery 189, 2.5 V, from a minimum voltage magnitude of the voltage range of the battery 189, 3.3 V. The processor 120 may determine the reference voltage to be greater than or equal to the cut-off voltage using the margin voltage that is set by considering the voltage range of the battery 189 and the cut-off voltage of the battery 189.
The example in which the reference voltage is determined based on the margin voltage and the voltage of the battery 189 from voltage levels in the set unit between the maximum charging voltage of the battery 189 and the cut-off voltage of the PCM 240 may be one of various embodiments and the electronic device 101 may determine the reference voltage in a different method from the example described above. In another example, when the voltage of the battery 189 is 3.94 V and the set margin voltage is 300 mV, the reference voltage may be determined to be 3.64 V, or when the voltage of the battery 189 is greater than or equal to 3 V and less than or equal to 3.3 V, the reference voltage may be determined to be 2.7 V.
According to various embodiments, the electronic device 101 may prevent and/or reduce or block the electronic device 101 from being set to the ship mode before the user input A to turn off the power of the electronic device 101 is received. Since the user uses the electronic device 101 before the user input to turn off the power is received, the power may need to be supplied to components of the electronic device 101.
For example, the electronic device 101 may set the reference voltage before the user input to turn off the power is received by considering the cut-off voltage of the battery 189. For example, the cut-off voltage of the battery 189 may be a voltage at which the PCM 240 operates to prevent and/or reduce overdischarge of the battery 189.
For example, the electronic device 101 may turn off the power. Turning off the power of the electronic device 101 may represent that a program or an operating system (OS) executed by the processor 120 is terminated and the power supplied to components in the electronic device 101, such as the processor 120, an IC, a display module, a sound output module, a communication module, an audio module, a sensor module, a haptic module, or a camera module, is blocked.
For example, the power management module 188 may monitor a voltage of the battery 189 after turning off the power of the electronic device 101. After the power of the electronic device 101 is turned off, the power may not be supplied to components in the electronic device 101, such as the processor 120, but the voltage of the battery 189 may drop due to a leakage current. For example, after turning off the power, the voltage of the battery 189 monitored by the power management module 188 may gradually decrease.
For example, the power management module 188 may determine whether to change the electronic device 101 to be in a ship mode based on the monitored voltage of the battery 189 and a reference voltage to enter the ship mode.
For example, when the monitored voltage of the battery 189 is less than or equal to the reference voltage, the power management module 188 may set the electronic device 101 to the ship mode. For example, when the voltage of the battery 189 is 3.9 V and the set reference voltage is 3.6 V at the time of receiving the user input to turn off the electronic device 101, the voltage of the battery 189 may gradually decrease due to a leakage current after the power of the device is turned off. When the monitored voltage of the battery 189 is less than or equal to 3.6 V, the power management module 188 may set the electronic device 101 to the ship mode. For example, a case in which the voltage of the battery 189 becomes less than or equal to the reference voltage because of a voltage decrease due to a leakage current may represent a state in which the electronic device 101 has not been used for a long time.
For example, when the monitored voltage of the battery 189 is maintained to be less than or equal to the reference voltage for more than or equal to a set debounce time, the power management module 188 may set the electronic device 101 to the ship mode. For example, the debounce time may be set to be one of 1, 4, 16, 32, and 64 seconds. The above example of the debounce time may be one of various embodiments and as an example different from the above example, the debounce time may be variously set, such as 1 hour or 24 hours.
For example, the power management module 188 may check the leakage current of the electronic device 101 to determine that the power of the electronic device 101 is turned off when entering the ship mode. For example, the leakage current of the electronic device 101 may be a current output from the battery 189 when the electronic device 101 is turned off.
The power management module 188 in various embodiments may control an operation of the switch 250. The power management module 188 may set the electronic device 101 to the ship mode by controlling the operation of the switch 250. For example, the switch 250 may be connected to the battery 189 and may transmit the power to the electronic device 101. For example, the switch 250 may form a path to transmit the power output by the battery 189 to components (e.g., the processor 120, an IC, the display module 160, the sound output module 155, the communication module 190, the audio module 170, the sensor module 176, the haptic module 179, and the camera module 180) of the electronic device 101.
For example, the power management module 188 may turn off the switch 250. When the switch 250 is turned off, a path through which the leakage current flows from the battery 189 to components of the electronic device 101 may be blocked. For example, the power management module 188 may turn off the switch 250 and may set the electronic device 101 to the ship mode.
The electronic device 101 in various embodiments may store power gauge data related to a state of the battery 189 in a memory 130 or 231. For example, the power management module 188 may store the power gauge data in the memory 130 or 231 of the power gauge 230 using the MCU 290. For example, the power management module 188 may store the power gauge data in the memory 130 or 231 using the MCU 290.
In another example, the processor 120 may store the power gauge data in the memory 130. For example, the processor 120 may identify the power gauge data through the interface module 275 of the power management module 188 and may store the identified power gauge data in the memory 130.
The ship mode of the electronic device 101 in various embodiments may be canceled when a power key is input or the adapter 300 is inserted. For example, the power management module 188 may identify that a power key is input in the ship mode or external power is input through the adapter 300.
For example, when the power key is input, the power management module 188 may receive a power key input. For example, the power control module 270 of the power management module 188 may be connected to the power key. For example, when the adapter 300 is inserted, the power management module 188 may identify that external power is input through the adapter 300. For example, the power control module 270 of the power management module 188 may identify that external power is input by sensing a voltage and/or a voltage of the input external power. For example, the power management module 188 may cancel the ship mode of the electronic device 101 by turning on the switch 250 when the power key is input or the adapter 300 is inserted.
The electronic device 101 in various embodiments may load the power gauge data from the memory 130 or 231 when the ship mode is canceled. Loading the power gauge data from the memory 130 or 231 may refer to identifying the power gauge data stored in the memory 130 or 231.
For example, when the ship mode of the electronic device 101 is canceled, the power gauge 230 may load the power gauge data stored in the memory 231 of the power gauge 230. In another example, when the ship mode of the electronic 101 is canceled, the power control module 270 may identify the power gauge data stored in the memory 130 through the interface module 275 and the power gauge 230 may load the power gauge data from the power control module 270.
According to various embodiments, the power gauge data may be prevented or blocked from being initialized by storing the power gauge data in the memory when the electronic device 101 is set to the ship mode or before the electronic device 101 is set to the ship mode, and loading the power gauge data when the ship mode of the electronic device 101 is canceled or after the ship mode of the electronic device 101 is canceled.
The power gauge 230 in various embodiments may be electrically connected to the processor 120 and/or the battery 189. For example, the processor 120 may be electrically connected to the power gauge 230 and may identify the power gauge data, which is information on the state of the battery 189. In another example, the processor 120 may communicate with the power control module 270 through the interface 275 and may identify the power gauge data stored in the power gauge 230 from the power control module 270.
For example, the power gauge 230 may be electrically connected to the battery 189 and may measure use state information (e.g., the capacity, the number of charge and discharge cycles, the voltage, or the temperature of the battery 189) on the battery 189.
The electronic device 101 in various embodiments may control the electronic device 101 to prevent the electronic device 101 from being set to the ship mode in an operation before a user input to turn off the power of the electronic device 101 is received. Since a user uses the electronic device 101 before the user input to turn off the power is received, the electronic device 101 may control the electronic device 101 to prevent the electronic device 101 from being set to the ship mode.
For example, when the electronic device 101 is turned on, the reference voltage may be set to a default level. For example, when the electronic device 101 operates at a voltage of the battery 189 between 3.4 V and 4.4 V, the reference voltage set to the default level may be a low value, such as 2.6 V.
For example, the electronic device 101 may set the reference voltage by considering a cut-off voltage of the battery 189. For example, when the electronic device 101 operates at a voltage of the battery 189 between 3.4 V and 4.4 V, the electronic device 101 may be automatically turned off until the voltage of the battery 189 reaches 3.4 V. After the electronic device 101 is turned off, the battery 189 may be discharged for a long period. For example, when the voltage of the battery 189 reaches a cut-off voltage, the PCM 240 may operate to prevent and/or reduce overdischarge of the battery 189. For example, when the cut-off voltage of the battery 189 is 2.5 V, the electronic device 101 may set the reference voltage, such as 2.6 V or 2.7 V, by considering the cut-off voltage of the battery 189.
For example, when the reference voltage is set by considering the cut-off voltage of the battery 189 and the user uses the electronic device 101, the electronic device 101 may not be set to the ship mode.
For example, when the reference voltage is set by considering the cut-off voltage of the battery 189 and the battery 189 reaches the reference voltage as the battery 189 is continuously discharged after the electronic device 101 is automatically turned off, the electronic device 101 may be set to the ship mode.
For example, the electronic device 101 may disable a function that the power management module 188 sets the electronic device 101 to be in the ship mode. For example, when the power of the electronic device 101 is turned on and the user uses the electronic device 101, the power management module 188 may disable the function to set the electronic device 101 to be in the ship mode. For example, when an input to turn off the power of the electronic device 101 is received from the user, the electronic device 101 may enable the function of the power management module 188 to set the electronic device 101 to the ship mode.

For example, the electronic device 101 may determine a change in a state of the electronic device 101 during a set second time period. When the state of the electronic device 101 does not change during the second time period, the electronic device 101 may output a signal to turn off the power.
For example, the electronic device 101 may determine whether the state of the electronic device 101 has changed based on a screen touch input through a display module (e.g., the display module 160 of
For example, when there is no screen touch input, key input, connection to a charger, a change in the operating status of the electronic device 101, and a change in the motion of the terminal during the second time period, it may be determined that there is no change in the state of the electronic device 101.
For example, when the signal to turn off the power is identified, the electronic device 101 may perform an operation to turn off the power of the electronic device 101. The electronic device 101 may terminate a running program or an OS and may block the power supplied to components, such as the processor 120, an IC, and the display module 160 in the electronic device 101.
For example, the electronic device 101 may count a set first time period from the time at which the signal to turn off the power is identified. For example, when the processor 120 identifies the signal to turn off the power, the processor 120 may transmit a control signal to the power management module 188. For example, the processor 120 may transmit the control signal to the power management module 270 through the interface module 275.
For example, the power management module 188 may count the set first time period based on the control signal. For example, the power control module 270 of the power management module 188 may count the set first time period.
For example, the electronic device 101 may determine the first time period based on a voltage magnitude of the battery 189. For example, the processor 120 may identify the voltage magnitude of the battery 189 when identifying the signal to turn off the power. For example, the processor 120 may determine the first time period having a positive correlation with the voltage magnitude of the battery 189 when identifying the signal to turn off the power.
For example, a voltage range of the battery 189 may be between about 3.3 V and about 4.4 V. For example, in a case in which the voltage magnitude of the battery 189 is 4.4 V when the signal to turn off the power is identified, the processor 120 may set the first time period to be 48 hours. For example, when the voltage magnitude of the battery 189 is 3.3 V at the time of identifying a signal to turn off the power, the processor 120 may determine the first time period to be 24 hours.
In the example described above, the first time period determined based on the voltage range of the battery 189 and the voltage magnitude of the battery 189 is an example and the example is not limited thereto.
For example, the electronic device 101 may set the electronic device 101 to the ship mode after the first time period has elapsed. For example, after the first time period has elapsed, the power control module 270 may set the electronic device 101 to the ship mode. For example, the power control module 270 may set the electronic device 101 to the ship mode by controlling an operation of the switch 250.
For example, after the first time period has elapsed, the electronic device 101 may set the electronic device 101 to the ship mode by turning off the switch 250. The power management module 188 may turn off the switch 250. When the switch 250 is turned off, a path through which the leakage current flows from the battery 189 to components of the electronic device 101 may be blocked. The power management module 188 may set the electronic device 101 to the ship mode by turning off the switch 250.
For example, the electronic device 101 may store power gauge data related to a state of the battery 189 in the memory 231. For example, the power control module 270 may store the power gauge data in the memory 231. For example, the power control module 270 may store the power gauge data in the memory 231 simultaneously with an operation of setting the electronic device 101 to the ship mode or may store the power gauge data in the memory 231 before or after the operation of setting the electronic device to the ship mode.
For example, when a power key is input or an adapter is inserted within the first time period, the electronic device 101 may stop counting the first time period.
For example, the electronic device 101 may set a mode to set the electronic device 101 to the ship mode based on a user input. For example, when setting to the mode to set to the ship mode, the electronic device 101 may be set to the ship mode after the first time period has elapsed after the power is turned off. For example, when the mode to set to the ship mode is not set, the electronic device 101 may not be set to the ship mode even if the first time period has elapsed after the power is turned off.
For example, when the power of the electronic device 101 is turned off based on a user input, the electronic device 101 may provide an interface to select the mode to set to the ship mode through the display module 160. For example, when a user desires to turn off the power of the electronic device 101 by inputting a power key, an interface to select power off, restart, power off, and enter ship mode may be provided.
For example, when identifying a signal to turn off the power depending on a change in a state of the electronic device 101 during the second time period, the electronic device 101 may operate based on a preset option regarding whether to enter the ship mode.
When a power key is input or an adapter is inserted after being set to the ship mode, the electronic device 101 may control the switch 250 that controls a path to transmit the power from the battery 189. The electronic device 101 may load the power gauge data stored in the memory 130 or 231.
When a power key is input or an adapter is inserted after being set to the ship mode, the electronic device 101 may cancel the ship mode of the electronic device 101 by turning on the switch 250. The power management module 188 may cancel the ship mode of the electronic device 101 by turning on the switch 250 when the power key is input or the adapter 300 is inserted.

For example, the electronic device 101 may set the reference voltage using a magnitude obtained by subtracting the margin voltage from the identified voltage of the battery 189. For example, the magnitude of the margin voltage may be set to a designated value.
For example, in operation 304, the electronic device 101 may perform an operation to turn off the power. For example, the electronic device 101 may terminate an OS or a program executed by a processor (e.g., the processor 120 of
For example, in operation 305, the electronic device 101 may monitor the voltage of the battery 189 after turning off the power. For example, the power management module may identify the voltage of the battery 189 after turning off the power. Even after the power of the electronic device 101 is turned off, the voltage of the battery 189 may gradually drop due to a leakage current.
For example, the electronic device 101 may determine whether the voltage of the battery 189 is less than or equal to the reference voltage in operation 306. According to an embodiment, the electronic device 101 may determine whether the voltage of the battery 189 is less than or equal to the reference voltage at a predetermined cycle. For example, when the voltage of the battery 189 is less than or equal to the reference voltage in operation 306, in operation 307, the electronic device 101 may determine whether the time, for which the voltage of the battery 189 is maintained to be less than or equal to the reference voltage, is greater than or equal to the debounce time.
In operation 306 or 307, when the voltage of the battery 189 is greater than the reference voltage or the time, for which the voltage of the battery 189 is maintained to be less than or equal to the reference voltage, is less than the debounce time, the electronic device 101 may monitor the voltage of the battery 189 in accordance with operation 305. According to an embodiment, the electronic device 101 may monitor at a predetermined cycle whether the voltage of the battery 189 is less than or equal to the reference voltage and the time, for which the voltage of the battery 189 is maintained to be less than or equal to the reference voltage, is greater than the debounce time.

For example, in operation 311, the electronic device 101 may identify whether a power key is input or an adapter (e.g., the adapter 300 of
In another example, when the adapter is inserted in operation 311, the power management module may identify that the adapter is inserted and the power management module may cancel the ship mode of the electronic device 101.
For example, when the power key is input or the adapter is inserted in operation 311, in operation 312, the electronic device 101 may control an operation of the switch. For example, the power management module of the electronic device 101 may control an operation of the switch, thereby, may form a path for transmitting the power from the battery 189 to components in the electronic device 101, such as the processor 120, an IC, a display module, a sound output module, a communication module, an audio module, a sensor module, a haptic module, or a camera module.
For example, in operation 313, the electronic device 101 may load the power gauge data from the memory. The electronic device 101 may load the power gauge data stored in the memory and the power gauge may identify the loaded power gauge data. As the electronic device 101 loads the power gauge data stored in the memory, the power gauge data may be prevented from being reset even when the electronic device 101 is set to the ship mode and then the ship mode is canceled.

In an embodiment, in operation 404, the electronic device 101 may set the electronic device 101 to the ship mode based on a change in the voltage of the battery 189 within a set time period after turning off the power.
For example, after the power of the electronic device 101 is turned off, the voltage of the battery 189 may decrease due to a leakage current. The amount of voltage decrease of the battery 189 due to the leakage current may be significantly smaller than the voltage decrease of the battery 189 due to an operation of the electronic device 101. For example, the electronic device 101 may determine whether the power of the electronic device 101 is normally turned off using the decreased voltage magnitude of the battery 189 during the set time period.
For example, the amount of voltage decrease of the battery 189 within 24 hours from an operation of turning off the power of the electronic device 101 is less than or equal to 1 mV, the electronic device 101 may determine that the power of the electronic device 101 is normally turned off.

After the electronic device 101 is set to the ship mode, the magnitude of the leakage current may be about 30 uA. After the voltage of the battery 189 reaches a V1 voltage (e.g., 2.6 V), the electronic device 101 may be set to the ship mode and after the electronic device 101 is set to the ship mode, the voltage of the battery 189 may reach a V2 voltage (e.g., 1.5 V) at which the battery 189 is overdischarged. In the example described above, a standby time taken for the voltage of the battery 189 to reach the V1 voltage may be about 13.9 months (3,000 mAh/300 uA=10,000 h), and a standby time taken to reach the V2 voltage after reaching the V1 voltage may be about 1.38 months (30 mAh/30 uA=1000 h). When the voltage of the battery 189 when turning off the power is about 4.0 V, the total standby time taken to reach the V2 voltage may be about 15.28 months.

For example, the total capacity of the battery 189 may be about 5,000 mAh, the voltage of the battery when the power is turned off may be about 4.0 V, the remaining capacity of the battery 189 when the power is turned off may be about 3,000 mAh, and a magnitude of the leakage current after the electronic device 101 is set to the ship mode may be about 30 uA. When the electronic device 101 is set to the ship mode after the power of the electronic device 101 is turned off and the set first time period (e.g., 24 hours, 48 hours, and the like) has elapsed, the time taken for the voltage of the battery 189, which is about 4.0 V, to reach the V1 voltage may be about 139 months (3,000 mAh/30 uA=100,000 h). The electronic device 101 may set the electronic device 101 to the ship mode when the set first time period has elapsed after the power is turned off, thereby, may increase the standby time taken for the voltage of the battery 189 to reach the V1 voltage.

It should be appreciated that embodiments of the disclosure and the terms used therein are not intended to limit the technological features set forth herein to particular embodiments and include various changes, equivalents, or replacements for a corresponding embodiment. In connection with the description of the drawings, like reference numerals may be used for similar or related components. It is to be understood that a singular form of a noun corresponding to an item may include one or more of the things, unless the relevant context clearly indicates otherwise. As used herein, “A or B,” “at least one of A and B,” “at least one of A or B,” “A, B or C,” “at least one of A, B and C,” and “at least one of A, B, or C,” each of which may include any one of the items listed together in the corresponding one of the phrases, or all possible combinations thereof. Terms such as “1st,” “2nd,” or “first” or “second” may simply be used to distinguish the component from other components in question, and do not limit the components in other aspects (e.g., importance or order). It is to be understood that if an element (e.g., a first element) is referred to, with or without the term “operatively” or “communicatively,” as “coupled with,” “coupled to,” “connected with,” or “connected to” another element (e.g., a second element), the element may be coupled with the other element directly (e.g., by wire), wirelessly, or via a third element.
As used in connection with embodiments of the disclosure, the term “module” may include a unit implemented in hardware, software, or firmware, or any combination thereof, and may interchangeably be used with other terms, for example, “logic,” “logic block,” “part,” or “circuitry.” A module may be a single integral component, or a minimum unit or part thereof, adapted to perform one or more functions. For example, according to an embodiment, the module may be implemented in a form of an application-specific integrated circuit (ASIC).
Embodiments as set forth herein may be implemented as software (e.g., the program 140) including one or more instructions that are stored in a storage medium (e.g., an internal memory 136 or an external memory 138) that is readable by a machine (e.g., the electronic device 101). For example, a processor (e.g., the processor 120) of the machine (e.g., the electronic device 101) may invoke at least one of the one or more instructions stored in the storage medium and execute it. This allows the machine to be operated to perform at least one function according to the at least one instruction invoked. The one or more instructions may include code generated by a compiler or code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. Here, the “non-transitory” storage medium is a tangible device, and may not include a signal (e.g., an electromagnetic wave), but this term does not differentiate between where data is semi-permanently stored in the storage medium and where the data is temporarily stored in the storage medium.
According to an embodiment, a method according to embodiments of the disclosure may be included and provided in a computer program product. The computer program product may be traded as a product between a seller and a buyer. The computer program product may be distributed in the form of a machine-readable storage medium (e.g., compact disc read-only memory (CD-ROM)), or be distributed (e.g., downloaded or uploaded) online via an application store (e.g., PlayStore™), or between two user devices (e.g., smartphones) directly.
