Detailed Description
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the present specification and the drawings, substantially the same elements and functions will be denoted by the same reference numerals, and repetitive description thereof will be omitted. Moreover, descriptions of functions and constructions well known in the art may be omitted for clarity and conciseness.
Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Fig. 1 is a block diagram showing an overall configuration of an electronic apparatus 1 according to an embodiment of the present invention. The electronic device 1 according to an embodiment of the present invention may be an electronic device such as a notebook computer, a tablet computer, a smartphone, a personal digital assistant, a smart wearable device, or the like. For convenience of explanation, a smartphone will be described as an example of the electronic apparatus 1. As shown in fig. 1, the smartphone 1 includes a battery 11, a storage unit 12, a battery level detection unit 13, and a control unit 14.
The battery 11 is configured to power the electronic device 1. The battery 11 may be implemented by a nickel-cadmium battery, a nickel-hydrogen battery, a lithium ion battery, a polymer battery, or the like, and the battery 11 may be implemented by one battery or a plurality of batteries.
The storage unit 12 is configured to store first activity schedule information in advance, wherein the first activity schedule information includes a first activity schedule end time point, and a time length from the first activity schedule end time point to a current time point is a first time period. The storage unit 12 may be a non-volatile memory such as a flash memory, a hard disk drive, an optical disk drive, or the like.
The battery level detection unit 13 is configured to detect the remaining level of the battery. The battery level detecting unit 13 may be a battery voltage detecting circuit that obtains the remaining level of the battery by detecting the voltage of the battery at predetermined time intervals. However, the battery level detection unit 13 is not limited thereto, and those skilled in the art can select the configuration of the battery level detection unit 13 as needed as long as the remaining level of the battery can be detected. Further, the predetermined time interval is preferably 1 second, however, the present invention is not limited thereto, and the predetermined time interval may be set as needed by those skilled in the art. Further, the operation of the battery level detection unit 13 to detect the remaining level may also be triggered by the user as needed. The detected remaining capacity may be a percentage of the current capacity of the battery 11 to the full state capacity of the battery 11.
The control unit 14 is configured to estimate a usage time of the remaining power and compare the usage time with the first time period, wherein if the usage time is less than or equal to the first time period, the control unit 14 controls the smartphone 1 to enter the low power consumption mode. The control unit 14 may be a processor such as a Central Processing Unit (CPU). However, the control unit 14 is not limited thereto, and may be implemented by any type of processing unit, micro-processing unit, or the like. The low power consumption mode may be one or more of reducing the brightness of the display screen of the smartphone 1, reducing the frequency of the processor of the smartphone 1, turning off the wifi element of the smartphone 1, and turning off the specific application program that the smartphone 1 is running, but the low power consumption mode is not limited thereto as long as reduction of the power consumption of the smartphone 1 can be achieved. In addition, if the use time is less than or equal to the first time period, the control unit can also prompt a user to charge the smart phone.
The estimation of the time of use of the remaining amount of power by the control unit 14 can be typically considered based on the two time periods of the first active schedule period and the period from the current time to the start time point of the first active schedule. For example, the prediction may be performed by performing a default operation of the smartphone during the first active schedule, or may be performed according to an expected operation condition of the smartphone 1 during the first active schedule, and simultaneously considering an expected operation condition of the smartphone during a period from the current time point to the start time point of the first active schedule. In some cases, the estimation may also be performed according to only one of the two periods, for example, when the starting time point of the first activity schedule is far away from the current time, it is determined that the remaining power cannot support the smartphone 1 to operate to the starting time point of the first activity schedule; or when the starting time point of the first activity schedule is closer to the current time, it is determined that the remaining power can support the smartphone 1 to work until the first activity schedule is finished. The estimation of the usage time of the detected remaining capacity by the control unit 14 will be described later in detail by way of specific examples.
The control unit 14 can read the first activity schedule information stored in the storage unit 12 and extract a first activity schedule end time point included in the first activity schedule information, and further determine a first time period based on the first activity schedule end time point and a current time point by comparing. The extraction of the end point of the active schedule by the control unit 14 may be performed based on time node information in the active schedule information (for example, time node information such as "10-12 points" appears in the active schedule information), or may be performed when the user sets that the active schedule information is a corresponding point of time selected by the user as the end point of the active schedule. Similarly, the extraction of the start time point of the active schedule by the control unit 14 can also be performed in a similar manner.
Further, the control unit 14 can also read the detected remaining power from the battery power detection unit 13. It is worth mentioning that the above operations of the control unit 14 (i.e. reading the first activity schedule information and determining the first time period, reading the detected remaining power) may be performed at predetermined time intervals, may be performed when the user stores the activity schedule information in the storage unit 12, or may be triggered by the user as desired.
The electronic apparatus 1 according to the embodiment of the present invention will be described in detail below with specific examples.
Suppose that a user presets an activity schedule message in a mobile phone calendar of a smart phone: "this morning at 10-12 pm in the morning". It should be understood that the activity schedule information is stored in the storage unit 12 in the form of activity schedule information data. The schedule information includes an end point of the schedule, i.e., 12 points, and further, it is assumed that the current time is 9 am. Therefore, the length of time between the end time point of the activity schedule and the current time point is three hours, that is, the first period of time is three hours. The battery level detection unit 13 detects the remaining level of the battery and assumes that the obtained remaining level is 50%. The control unit 14 estimates the usage time of the remaining capacity and compares the usage time with the first time period, and selects further processing according to the result of the comparison. Assuming that the estimated time of use is 5 hours, the control unit 14 will not further process this situation since the estimated time of use is greater than the first time period; assuming that the estimated usage time is 2 hours, since the estimated usage time is less than the first time period, the control unit 14 controls the smartphone 1 to enter the low power consumption mode.
Through the configuration, the smart phone 1 according to the present invention determines whether to enable the electronic device to enter the low power consumption mode by estimating the usage time of the remaining power of the battery 11 and determining whether the usage time can cover the whole course of the activity corresponding to the activity schedule information based on the pre-stored activity schedule information, so that it is not necessary for a user to subjectively determine whether the remaining power of the electronic device is sufficient or to actively operate to enter the low power consumption mode, and the power management policy of the electronic device can be more intelligently adjusted, thereby avoiding the situation that the power of the smart phone 1 is exhausted during the activity schedule, and effectively improving the usage experience of the user.
The use time of the control unit 14 to estimate the remaining power will be described in detail below by way of specific examples.
The control unit 14 may set a default operation for the active schedule of the smartphone 1, i.e. during the active schedule, the control unit 14 estimates the usage time of the remaining amount of power by the default operation regardless of the expected operation of the smartphone 1, i.e. the control unit 14 estimates the usage time of the remaining amount of power according to the default operation and the operation during the non-active schedule.
Taking the above-mentioned activity schedule information "10 am to 12 am meeting today" as an example, assuming that the current time is 9 am and the user is browsing the web page using the smart phone 1, the control unit 14 can estimate 9 am to 10 am(start time of the activity schedule) period (during which the control unit 14 assumes that the user continues the same operation) the power consumption I of the smartphone 1 due to the user browsing the web page1(power consumption per unit time for browsing web pages × 1 hour). Further, the control unit 14 may set the standby operation as a default operation of the active schedule, i.e. default to the smartphone 1 remaining in standby during the active schedule. The power consumption of the standby operation per unit time is known to the control unit 14. Further, the control unit 14 subtracts the power consumption amount I from the remaining power amount detected by the battery power amount detection unit 131The remaining power I to the beginning of the activity schedule can be estimated2Then the remaining capacity I2Dividing the power consumption of the standby operation in unit time to obtain the remaining power I2The smartphone 1 may be made to support this standby operation time. The usage time of the detected remaining power can be estimated by adding the time to the time (1 hour) from the current time point to the start time point of the schedule.
In the above example, how the smartphone 1 obtains the power consumption for browsing the web page in the unit time and the power consumption for the standby operation in the unit time is a known technology in the art, and the details are not described here.
Although the standby operation is set as the default operation in the above example, the present invention is not limited thereto. Operations such as calling, browsing a webpage, watching a video and the like can also be set as default operations.
Alternatively, the control unit 14 may set the power consumption amount during the active schedule period only according to the length of the active schedule period without setting the default operation for the active schedule period. In the above-mentioned case of the activity schedule information "meeting at 10 pm to 12 pm today", it is assumed that the control unit 14 sets the power consumption amount of the activity schedule period (10 pm to 12 pm) to 20% (power consumption 10% per hour), it is assumed that the battery power detection unit 13 detects that the current remaining power amount is 50%, the control unit 14 estimates that the power consumption amount of the 9 pm to 10 pm smartphone 1 caused by the user browsing the web page is 40%, and the control unit 14 may estimate that the usage time of the current 50% remaining power amount is 2 hours.
Alternatively, the activity schedule information stored in advance in the storage unit 12 may further include an activity schedule keyword associated with an operation to be performed by the smartphone 1 during the activity schedule. Still taking the activity schedule information "10-12 am today's meeting" as an example, where "meeting" is a keyword for the activity schedule, it means that during 10-12 am today, the user of smartphone 1 will be in a meeting and smartphone 1 will be in a standby state during this time. For another example, the activity schedule information preset in the smart phone 1 by the user is: "cell phone read email" at 10-12 am today, wherein "cell phone read email" is a keyword for the activity schedule, which means that during 10-12 am, the user of the smartphone 1 will use the smartphone 1 to read email and the smartphone 1 will be in use and display, send and receive email during this time.
The control unit 14 estimates the use time of the remaining power according to the operation corresponding to the active schedule keyword and the operation during the non-active schedule period. Specifically, the control unit 14 can obtain the power consumption of the smartphone 1 for the standby operation per unit time and for reading the e-mail per unit time according to the above-mentioned well-known technique. In addition, the control unit 14 estimates the power consumption from the current time point to the start time point of the activity schedule (9 to 10 points), which is similar to the above-described example and will not be described again. Thereby, the control unit 14 can estimate the use time of the remaining power detected by the battery power detection unit 13. It should be noted that the above-mentioned "operation during non-active schedule" may include not only the operation from the current time point to the start time point of the active schedule but also the operation after the end time point of the active schedule. For example, when the user sets a plurality of activity schedule information, the control unit 14 may estimate whether the detected remaining power can support the smartphone 1 to operate until the plurality of activity schedules end. The case of the plurality of activity schedule information will be described in detail later.
Although two examples of keywords of an active schedule are shown above, the present invention is not limited thereto. The smartphone 1 may also store in advance in the storage unit 12 an association table of the activity schedule keywords with the operation of the smartphone 1. When the user sets the activity schedule information in the smartphone 1, the control unit 14 may automatically determine the operation of the smartphone 1 during the activity schedule with reference to the association table, and further estimate the usage time of the detected remaining power. In addition, when the user sets the activity schedule information in the smartphone 1, the user may also manually select an operation to be performed by the smartphone 1 during the activity schedule, and the smartphone 1 may also provide a plurality of activity schedule operation options for the user to select. Therefore, the operation of the smartphone 1 during the active schedule can be more accurately and intelligently determined based on the active schedule information, thereby further improving the accuracy of estimating the usage time of the detected remaining power.
It should be noted that, in some cases, the control unit 14 may estimate the usage time of the detected remaining power without the need to estimate the usage time of the remaining power according to the operation of the smartphone 1 during the active schedule. Still taking the above-mentioned activity schedule information "meeting at 10 pm to 12 pm today" as an example, assuming that the current time is 9 pm and the remaining power of the smartphone 1 is 50%, at this time, the user is watching a movie using the smartphone 1 (the power consumption of the smartphone in a unit time during playing the movie is known according to the above-mentioned well-known technology), the control unit 14 estimates that the remaining power cannot enable the smartphone 1 to operate to the activity schedule starting time point (10 pm), that is, the use time of the remaining power is less than the first time period, so the control unit 14 controls the smartphone 1 to enter the low power consumption mode, or prompts the user to charge.
Further, when the start time point of the active schedule is closer to the current time, the control unit 14 may estimate the usage time of the detected remaining power only from the operation of the smartphone 1 during the active schedule, without considering the operation of the smartphone 1 during the current time point and the start time point of the active schedule.
The storage unit 12 may also be pre-stored with at least one second activity schedule information, wherein the second activity schedule information includes a second activity schedule start time point and a second activity schedule end time point, and the second activity schedule start time point is later than the first activity schedule end time point, the time length from the end time point of the second activity schedule to the current time point is a second time period, and if there are a plurality of second activity schedules, the plurality of second activity schedules do not temporally overlap with each other, wherein if the usage time is greater than the first time period, the control unit is further configured to compare the usage time with the second time period, wherein if the usage time is less than or equal to the second time period, the control unit controls the electronic device to enter a low power consumption mode.
For example, the user sets the following two pieces of activity schedule information in the smartphone 1: "this morning at 10-12 am", "this noon at 12-1 am work brief meal". The control unit 14 will predict the detected remaining power according to the two activity schedules by using the prediction method described above, so as to support the smartphone 1 to work until the second activity schedule is finished.
It is worth mentioning that, in view of the standard capacity of the battery 11 and the timeliness of the user using the mobile phone calendar, the control unit 14 preferably predicts whether the detected remaining power can support the operation of the smartphone 1 to the end of the activity schedule with respect to the activity schedule information(s) recorded in the mobile phone calendar in the current time point of the day.
A method 200 of adjusting a power management policy according to an embodiment of the invention is described below with reference to fig. 2. Fig. 2 is a flow diagram illustrating a method 200 of adjusting a power management policy applied to the electronic device 1 according to an embodiment of the present invention. The method 200 for adjusting the power management policy will be described with reference to the electronic device 1 shown in fig. 1, and therefore, in order to make the description more concise, a detailed description of each component in the electronic device 1 will be omitted here. Also, a smartphone will be described hereinafter as an example of the electronic apparatus 1.
As shown in fig. 2, in step S201, the smartphone 1 is powered by the battery 11.
In step S202, first activity schedule information is stored in the storage unit 12 in advance, the first activity schedule information including a first activity schedule end time point, wherein a time length from the first activity schedule end time point to a current time point is a first time period.
In step S203, the remaining capacity of the battery 11 is detected by the battery capacity detection unit 13.
Specifically, the battery level detection unit 13 may be a battery voltage detection circuit that obtains the remaining level of the battery by detecting the voltage of the battery at predetermined time intervals. However, the battery level detection unit 13 is not limited thereto, and those skilled in the art can select the configuration of the battery level detection unit 13 as needed as long as the remaining level of the battery can be detected. Further, the predetermined time interval is preferably 1 second, however, the present invention is not limited thereto, and the predetermined time interval may be set as needed by those skilled in the art. Further, the operation of the battery level detection unit 13 to detect the remaining level may also be triggered by the user as needed. The detected remaining capacity may be a percentage of the current capacity of the battery 11 to the full state capacity of the battery 11.
In step S204, the usage time of the remaining power is estimated by the control unit 14, and the usage time is compared with the first time period, wherein if the usage time is less than or equal to the first time period, the electronic device is controlled to enter a low power consumption mode.
The control unit 14 may be a processor such as a Central Processing Unit (CPU). However, the control unit 14 is not limited thereto, and may be implemented by any type of processing unit, micro-processing unit, or the like. The low power consumption mode may be one or more of reducing the brightness of the display screen of the smartphone 1, reducing the frequency of the processor of the smartphone 1, turning off the wifi element of the smartphone 1, and turning off the specific application program that the smartphone 1 is running, but the low power consumption mode is not limited thereto as long as reduction of the power consumption of the smartphone 1 can be achieved. In addition, if the use time is less than or equal to the first time period, the control unit can also prompt a user to charge the smart phone.
In step S204, the estimation of the usage time of the remaining amount of power by the control unit 14 can be generally considered based on the two periods of the first active schedule period and the period from the current time to the start time point of the first active schedule. For example, the prediction may be performed by performing a default operation of the smartphone during the first active schedule, or may be performed according to an expected operation condition of the smartphone 1 during the first active schedule, and simultaneously considering an expected operation condition of the smartphone during a period from the current time point to the start time point of the first active schedule. In some cases, the estimation may also be performed according to only one of the two periods, for example, when the starting time point of the first activity schedule is far away from the current time, it is determined that the remaining power cannot support the smartphone 1 to operate to the starting time point of the first activity schedule; or when the starting time point of the first activity schedule is closer to the current time, it is determined that the remaining power can support the smartphone 1 to work until the first activity schedule is finished. The estimation of the usage time of the detected remaining capacity by the control unit 14 will be described later in detail by way of specific examples.
The control unit 14 can read the first activity schedule information stored in the storage unit 12 and extract a first activity schedule end time point included in the first activity schedule information, and further determine a first time period based on the first activity schedule end time point and a current time point by comparing. The extraction of the end point of the active schedule by the control unit 14 may be performed based on time node information in the active schedule information (for example, time node information such as "10-12 points" appears in the active schedule information), or a corresponding point of time may be selected by the user as the end point of the active schedule when the user sets the active schedule information. Similarly, the extraction of the start time point of the active schedule by the control unit 14 can also be performed in a similar manner.
Further, the control unit 14 can also read the detected remaining power from the battery power detection unit 13. It is worth mentioning that the above operations of the control unit 14 (i.e. reading the first activity schedule information and determining the first time period, reading the detected remaining power) may be performed at predetermined time intervals, may be performed when the user stores the activity schedule information in the storage unit 12, or may be triggered by the user as desired.
The method 200 for adjusting the power management policy will be described in detail below with specific examples.
Suppose that a user presets an activity schedule message in a mobile phone calendar of a smart phone: "this morning at 10-12 pm in the morning". It should be understood that the activity schedule information is stored in the storage unit 12 in the form of activity schedule information data. The schedule information includes an end point of the schedule, i.e., 12 points, and further, it is assumed that the current time is 9 am. Therefore, the length of time between the end time point of the activity schedule and the current time point is three hours, that is, the first period of time is three hours. The battery level detection unit 13 detects the remaining level of the battery and assumes that the obtained remaining level is 50%. The control unit 14 estimates the usage time of the remaining capacity and compares the usage time with the first time period, and selects further processing according to the result of the comparison. Assuming that the estimated time of use is 5 hours, the control unit 14 will not further process this situation since the estimated time of use is greater than the first time period; assuming that the estimated usage time is 2 hours, since the estimated usage time is less than the first time period, the control unit 14 controls the smartphone 1 to enter the low power consumption mode.
Through the method, the method 200 for adjusting the power management policy according to the present invention determines whether to enable the electronic device to enter the low power consumption mode by estimating the usage time of the remaining power of the battery 11 and determining whether the usage time can cover the whole activity course corresponding to the activity schedule information based on the pre-stored activity schedule information, so that it is not necessary for a user to subjectively determine whether the remaining power of the electronic device is sufficient or actively operate to enter the low power consumption mode, and the power management policy of the electronic device can be adjusted more intelligently, thereby avoiding the situation that the power of the smartphone 1 is exhausted during the activity schedule, and effectively improving the usage experience of the user.
The details of the usage time of the control unit 14 estimated the remaining capacity in step S204 will be described below by way of specific examples.
The control unit 14 may set a default operation for the active schedule of the smartphone 1, i.e. during the active schedule, the control unit 14 estimates the usage time of the remaining amount of power by the default operation regardless of the expected operation of the smartphone 1, i.e. the control unit 14 estimates the usage time of the remaining amount of power according to the default operation and the operation during the non-active schedule.
Taking the above-mentioned "10 am-12 am meeting today" as an example, assuming that the current time is 9 am and the user is browsing the web page using the smartphone 1, the control unit 14 can estimate the power consumption I of the smartphone 1 caused by the user browsing the web page during the period from 9 am to 10 am (the start time of the activity schedule) (the control unit 14 assumes that the user continues the same operation during this period)1(power consumption per unit time for browsing web pages × 1 hour). Further, the control unit 14 may set the standby operation as a default operation of the active schedule, i.e. default to the smartphone 1 remaining in standby during the active schedule. The power consumption of the standby operation per unit time is known to the control unit 14. Further, the control unit 14 subtracts the power consumption amount I from the remaining power amount detected by the battery power amount detection unit 131The remaining power I to the beginning of the activity schedule can be estimated2Then the remaining capacity I2Dividing the power consumption of the standby operation in unit time to obtain the remaining power I2The smartphone 1 may be made to support this standby operation time. The usage time of the detected remaining power can be estimated by adding the time to the time (1 hour) from the current time point to the start time point of the schedule.
In the above example, how the smartphone 1 obtains the power consumption for browsing the web page in the unit time and the power consumption for the standby operation in the unit time is a known technology in the art, and the details are not described here.
Although the standby operation is set as the default operation in the above example, the present invention is not limited thereto. Operations such as calling, browsing a webpage, watching a video and the like can also be set as default operations.
Alternatively, in step S204, the control unit 14 may set the power consumption amount of the active schedule period only according to the length of the active schedule period without setting a default operation for the active schedule period. In the above-mentioned case of the activity schedule information "meeting at 10 pm to 12 pm today", it is assumed that the control unit 14 sets the power consumption amount of the activity schedule period (10 pm to 12 pm) to 20% (power consumption 10% per hour), it is assumed that the battery power detection unit 13 detects that the current remaining power amount is 50%, the control unit 14 estimates that the power consumption amount of the 9 pm to 10 pm smartphone 1 caused by the user browsing the web page is 40%, and the control unit 14 may estimate that the usage time of the current 50% remaining power amount is 2 hours.
Alternatively, in step S202, the activity schedule information pre-stored in the storage unit 12 may further include an activity schedule keyword, wherein the activity schedule keyword is associated with an operation to be performed by the smartphone 1 during the activity schedule. Still taking the activity schedule information "10-12 am today's meeting" as an example, where "meeting" is a keyword for the activity schedule, it means that during 10-12 am today, the user of smartphone 1 will be in a meeting and smartphone 1 will be in a standby state during this time. For another example, the activity schedule information preset in the smart phone 1 by the user is: "cell phone read email" at 10-12 am today, wherein "cell phone read email" is a keyword for the activity schedule, which means that during 10-12 am, the user of the smartphone 1 will use the smartphone 1 to read email and the smartphone 1 will be in use and display, send and receive email during this time.
In step S204, the control unit 14 may estimate the usage time of the remaining power according to the operation corresponding to the active schedule keyword and the operation during the non-active schedule period. Specifically, the control unit 14 can obtain the power consumption of the smartphone 1 for the standby operation per unit time and for reading the e-mail per unit time according to the above-mentioned well-known technique. In addition, the control unit 14 estimates the power consumption from the current time point to the start time point of the activity schedule (9 to 10 points), which is similar to the above-described example and will not be described again. Thereby, the control unit 14 can estimate the use time of the remaining power detected by the battery power detection unit 13. It should be noted that the above-mentioned "operation during non-active schedule" may include not only the operation from the current time point to the start time point of the active schedule but also the operation after the end time point of the active schedule. For example, when the user sets a plurality of activity schedule information, the control unit 14 may estimate whether the detected remaining power can support the smartphone 1 to operate until the plurality of activity schedules end. The case of the plurality of activity schedule information will be described in detail later.
Although two examples of keywords of an active schedule are shown above, the present invention is not limited thereto. In the method 200, an association table of the active schedule keyword with the operation of the smartphone 1 may also be stored in advance in the storage unit 12. When the user sets the activity schedule information in the smartphone 1, the control unit 14 may automatically determine the operation of the smartphone 1 during the activity schedule with reference to the association table, and further estimate the usage time of the detected remaining power. In addition, when the user sets the activity schedule information in the smartphone 1, the user may also manually select an operation to be performed by the smartphone 1 during the activity schedule, and the smartphone 1 may also provide a plurality of activity schedule operation options for the user to select. Therefore, the operation of the smartphone 1 during the active schedule can be more accurately and intelligently determined based on the active schedule information, thereby further improving the accuracy of estimating the usage time of the detected remaining power.
It should be noted that, in some cases, the control unit 14 may estimate the usage time of the detected remaining power without the need to estimate the usage time of the remaining power according to the operation of the smartphone 1 during the active schedule. Still taking the above-mentioned activity schedule information "meeting at 10 pm to 12 pm today" as an example, assuming that the current time is 9 pm and the remaining power of the smartphone 1 is 50%, at this time, the user is watching a movie using the smartphone 1 (the power consumption of the smartphone in a unit time during playing the movie is known according to the above-mentioned well-known technology), the control unit 14 estimates that the remaining power cannot enable the smartphone 1 to operate to the activity schedule starting time point (10 pm), that is, the use time of the remaining power is less than the first time period, so the control unit 14 controls the smartphone 1 to enter the low power consumption mode, or prompts the user to charge.
Further, when the start time point of the active schedule is closer to the current time, the control unit 14 may estimate the usage time of the detected remaining power only from the operation of the smartphone 1 during the active schedule, without considering the operation of the smartphone 1 during the current time point and the start time point of the active schedule.
In step S202, the storage unit 12 may also store at least one second activity schedule information in advance, wherein the second activity schedule information includes a second activity schedule start time point and a second activity schedule end time point, and the second activity schedule start time point is later than the first activity schedule end time point, the time length from the end time point of the second activity schedule to the current time point is a second time period, and if there are a plurality of second activity schedules, the plurality of second activity schedules do not temporally overlap with each other, wherein if the usage time is greater than the first time period, the control unit is further configured to compare the usage time with the second time period, wherein if the usage time is less than or equal to the second time period, the control unit controls the electronic device to enter a low power consumption mode.
For example, the user sets the following two pieces of activity schedule information in the smartphone 1: "this morning at 10-12 am", "this noon at 12-1 am work brief meal". The control unit 14 will predict the detected remaining power according to the two activity schedules by using the prediction method described above, so as to support the smartphone 1 to work until the second activity schedule is finished.
It is worth mentioning that, in view of the standard capacity of the battery 11 and the timeliness of the user using the mobile phone calendar, the control unit 14 preferably predicts whether the detected remaining power can support the operation of the smartphone 1 to the end of the activity schedule with respect to the activity schedule information(s) recorded in the mobile phone calendar in the current time point of the day.
