The loss is based on the current power consumption and the average power consumption per function -amp;~^, the power management program calculates the remaining use of one of the mobile communication devices. For example, the remaining usage time of the mobile communication device is calculated by Equation 2, which is described in the formula 2. In the formula 2, the pinitial is the initial power of the battery, which can be defined as the following two The first case: the battery is full, the initial battery charge can be assumed to be P. · 100% of the charge state; the second case: the mobile communication device has been used for two days' and it is assumed that 15 has been used. % of electricity' and 85% of the remaining power after rebooting, you can assume the battery The initial power Pinitial is 85% of the state of full charge. In addition, the battery level of the battery 201214100 can be known from the battery's specifications, for example, the battery capacity used is 8GGmAh. _ initial power = wire In the past - the sum of the past power consumption in the past, you can get the sum of the current power divided by the average power consumption of each function Ca ~ Ce ~ and '. The remaining usage time of the mobile communication device ^ electricity. After calculating the action rail device _ Yu (4) ^, the electricity will compare the remaining usage time Trest with a preset use time, / mileage time Trest is the ship paste T_ng ( ^ The time management program will = 1: the target power of the pool (return to step S12). ... When the remaining usage time τ is lower than the preset usage time Tsettmg, the power supply program will compare each of the subordinate functions. And the force sPe~Pe and - the first preset power consumption 'to determine whether each of the subordinate Wei's past power consumption PC~PQ is greater than the first pre-1# power consumption (step S20). When the past power consumption Pc~p_ When any one is greater than the first preset two-time, the power management program will close Corresponding subordinate function (step milk). In this embodiment, the __Tsetting and the first preset Wei can be preset values or set by the user. For example, suppose the preset usage time T y is 8 hours. The first preset power consumption is millimeter milliwatts, the past power consumption of the multimedia and body playback functions is Pc# 120 watts, and the past power consumption Pd of the game function is 8 〇 milliwatts' while the past power consumption of the navigation function is (9) milliwatts. When the remaining usage time of the 201214100 communication device is less than 8 hours, the multimedia power consumption function is due to the past power consumption Pc (120 milliwatts) of the multimedia playback function being greater than the first preset power consumption 〇〇〇 milliwatts) It will be turned off to extend the usage time of the necessary functions (the standby function and the call function are necessary functions in this embodiment). After the partial slave function is turned off, the power management program controls the mobile communication device to issue a message to prompt the user that the partial slave function has been turned off (step S24). That is, after the multimedia playing function is turned off, the mobile communication device can send a text message, vibrate or audible to prompt the user that the multimedia playing function has been turned off. After the partial shutoff is turned off, the power supply manifold will calculate the remaining time Trest', and again determine whether the recalculated remaining time ^ is greater than the preset use time Tsetting (step S26). If some subordinate functions are turned off, the remaining usage time will exceed the default setting. The Tsetting will continue to monitor the battery's target power (return to step S12). Conversely, if the remaining usage time U is lower than or equal, the pre-stay Tsetting 'the power management program will determine whether there is an unclosed slave function (step S28) e if there are still subordinate functions that have not been turned off, then Going back to step 20, the power g-hearted comparison compares the past power consumption Pd~Pe and the second preset miscellaneous (for example, 5() milliwatts of each subordinate function that have not been turned off, and the second power consumption is less than the above - Cai Miscellaneous). When the past pd~p_ towel is __ greater than the second preset power consumption, the power management process side _ should be a function and issue a prompt message (steps = 22 and S24), thereby achieving the extended fiber use time Trest, the goal of. In the same way, the pre-" power consumption can also be preset for the system or set by the user. 201214100 II: Base: Hair: = one:: Widely used as _ genus ^ As for the number of pre-mixed μ and the step size, the actual embodiment should be pre-described.

The subordinate functions that have not been closed are the game function and the navigation function. The past power consumption Pd of the game is 8 〇 mW, and the past power consumption of the navigation function is 60 mW. When the remaining usage time of the mobile communication device is still less than 8 hours, since the game skill _ past miscellaneous Pd (10) red) and navigation Wei _ de-power consumption (60 mW) are greater than the second preset power consumption mentioned above ( 5 〇m), so the game function and navigation function will be turned off' to extend the usage time of the necessary functions (in this embodiment, the standby function and the call function are necessary functions). After all the slave functions are turned off, the recalculated remaining usage time Trest is still lower than the preset usage time Tsetting', then the power management program will control the mobile communication device to send a message to prompt the lowest battery level (step S3〇) ). In other words, when there is no slave function that can be turned off, but the remaining usage time of the mobile communication device is still lower than or equal to the preset usage time Tsetting (for example, less than 8 hours), the mobile communication device will send a message. The user knows that the current battery level is close to the minimum power (eg 201214100 such as: 1G% of the battery full state or the battery voltage is 3 5V), and reminds the user to charge the mobile communication device. Then the power management program determines whether the current power is lower than the minimum power (step S32). When the current battery capacity is still greater than the minimum power, the power management program will continuously monitor the current battery power (return to step S12). If the user still does not charge the mobile communication device, the battery power is gradually consumed. When the current battery level is lower than the minimum battery level, the power management program will turn off the necessary functions (step s34). In this embodiment, since the standby function and the call function are necessary functions, the mobile communication device is turned off after the standby function and the call function are turned off. Referring to Figure 2, there is shown a flow chart of a power management method in accordance with another embodiment of the present invention.

When the remaining usage time 1' is lower than or equal to a preset usage time Tsetting (the judgment result of step 18) Yes)) The source management program compares the power consumption of each slave function to the power consumption Pc~Pe and the preset power consumption to determine whether the past power consumption of each slave function is greater than the preset power consumption, and the power management program will Comparing the past usage times Nc~Ne of each subordinate function with the preset usage times to determine whether the past usage times Nc~Ne of each subordinate function is greater than the preset usage count (step S2〇). When the past power consumption Pc~ If any of the Pes is greater than the preset power consumption and/or any of the past usage times Nc~Ne is less than the preset number of uses, the power management program will close the corresponding slave function (step S22'). In the default, the preset usage time can be set by the system φ value or set by the user. For example, 'Assume that the preset usage time Tsetting is 8 hours, the preset power consumption is 1 〇〇 milliwatt, and the preset usage frequency is 5 times 'multimedia playback function's past power consumption Pc is 120 mW and past usage times Nc is 8 times' game function's past power consumption Pd is 8 〇 mW and past usage times Nd is 6 times' navigation function's past work Consumption Pe is 60 mW and the number of past uses is Ne 3. When the remaining usage time of the mobile communication device is less than 4 hours, the past power consumption of the multimedia playback function Pc (12 〇 mW) is greater than 13 201214100 Preset power consumption (100 mW) 'The past usage count Ne (3 times) of the navigation function is less than the preset usage count (5 times), so the multimedia playback function and navigation function will be turned off. It should be noted that 'except the first picture and the first In the exception shown in the figure 2, when the remaining usage time is lower than or equal to the preset usage time, the power management program of the present invention may first compare the past usage times and the preset usage times of each subordinate function to determine each Whether the past usage of a subordinate function is greater than the preset usage count. When the number of used times is less than the preset number of uses, the power manager will close the corresponding slave function. § In the past, the responsibility of the fiscal amount - greater than or equal to the preset number of times ❿ when the 'power supply program is screaming again — to do Wei's past miscellaneous and preset power consumption, to determine whether the past power consumption of each of the woven functions is Greater than the preset power consumption. When the power consumption of the past is greater than the power consumption, the power management program will turn off the corresponding slave function. In summary, when the remaining money time of the electronic device is lower than the preset time, the money management method of the present invention can be borrowed by __ (that is, the power consumption of the past time period = peach) is larger and / Or subordinate functions with less usage in the past (that is, in the past period of time: the number of times used), with ___, thereby extending the usage time of the necessary functions. Duck Patent Range 14 201214100 [Simplified Schematic] FIG. 1 is a flow chart of a power management method according to an embodiment of the present invention. 2 is a flow chart of a power management method according to another embodiment of the present invention.
