And because the user does not know how long the battery can provide the electric quantity of the mobile terminal, the mobile terminal is shut down when the user uses the mobile terminal to operate the service, the service in operation is interrupted, and data generated in the operation service is lost.

Example two
Referring to fig. 2, an embodiment of the present invention provides a method for prompting battery power, including:
In step 201: detecting the remaining power of the battery of the mobile terminal in real time, and executing step 202 when detecting that the remaining power of the battery is reduced to a preset power threshold.
The remaining capacity of the battery of the mobile terminal is continuously reduced during the operation. In this step, the remaining power of the battery of the mobile terminal is collected in real time, the detected remaining power is compared with a preset power threshold, and when the detected remaining power is equal to the preset power threshold, the subsequent steps are executed.
the preset power threshold is generally small, for example, the preset power threshold may be 15%, 10%, 9%, or 8%, and when the remaining power of the battery of the mobile terminal decreases to the preset power threshold, it indicates that the remaining power of the battery is small, and the mobile terminal may be automatically powered off after waiting for a period of time. In order to enable a user to complete the ending work of the currently-performed service before the mobile terminal is powered off and to timely store data generated in the service process, the remaining time of the mobile terminal from the power-off state can be displayed according to the following flow, so that the user can arrange the ending work according to the remaining time.
In step 202: the current remaining capacity of the battery and the current capacity consumption rate of the mobile terminal are periodically acquired.
The method comprises the following steps: when detecting that the residual electric quantity of the battery is smaller than a preset electric quantity threshold value, starting to collect the current residual electric quantity of the battery once every preset period length; and calculating the electric quantity consumption of the mobile terminal in the current period according to the current residual electric quantity acquired in the current period and the residual electric quantity acquired in the last period, and calculating the current electric quantity consumption speed according to the electric quantity consumption of the mobile terminal in each period or partial period.
for example, assuming that the preset charge threshold is 10%, the preset period length is 10 seconds, and the current period is the third period, i.e., the first period and the second period have elapsed before the third period. The method comprises the steps that a first period starts when the fact that the residual capacity of a battery of the mobile terminal is reduced to 10% is detected, the 10 second time after the first period is the first period, the current residual capacity of the battery is collected to be 9.7% when the first period is ended, and the 9.7% of the residual capacity collected in the first period and the 0.3% of the electric quantity consumption of the mobile terminal in the first period are obtained; the 10 second time after the first period is finished is a second period, the current residual capacity of the battery is collected by 9.2% at the end of the second period, namely the residual capacity collected in the second period is 9.2%, and the electric quantity consumption of the mobile terminal in the second period is 0.5% according to the residual capacity 9.7% of the battery collected in the first period and the residual capacity 9.2% collected in the second period; the 10 second time after the second period is the third period, the current residual capacity of the battery is collected at 8.5% when the third period is finished, namely the residual capacity collected in the third period is 8.5%, and the electric quantity consumption of the mobile terminal in the third period is 0.7% according to the residual capacity 9.2% of the battery collected in the second period and the residual capacity 8.5% collected in the third period; and then calculating the current electricity consumption speed according to the electricity consumption of the mobile terminal in the first period of 0.3%, the electricity consumption of the mobile terminal in the second period of 0.5% and the electricity consumption of the mobile terminal in the third period of 0.7%.
The current power consumption rate can be calculated in two ways, including:
First, according to the power consumption of the mobile terminal in each period and a preset period length, the power consumption speed of the mobile terminal in each period is calculated, and the maximum power consumption speed is selected as the current power consumption speed of the mobile terminal.
Optionally, the amount of power consumption of the mobile terminal in a partial period may be selected, the selected rate of power consumption of the mobile terminal in each period is calculated according to the selected amount of power consumption of the mobile terminal in each period and the preset period length, and the maximum rate of power consumption is selected as the current rate of power consumption of the mobile terminal.
For example, according to the electric quantity consumption of the mobile terminal in the first period being 0.3% and the preset period length being 10 seconds, the electric quantity consumption speed of the mobile terminal in the first period is calculated to be 0.03% per second; calculating the electric quantity consumption speed of the mobile terminal in the second period to be 0.05% per second according to the electric quantity consumption of the mobile terminal in the second period of 0.5% and the preset period length of 10 seconds; calculating the electric quantity consumption speed of the mobile terminal in the third period to be 0.07% per second according to the electric quantity consumption of the mobile terminal in the third period of 0.7% and the preset period length of 10 seconds; the maximum power consumption rate of 0.07% per second is selected as the current power consumption rate of the mobile terminal. Or selecting the second period and the third period, and selecting the maximum power consumption rate of 0.07% per second as the current power consumption rate of the mobile terminal from the calculated power consumption rates of 0.05% per second and 0.07% per second of the second period.
and secondly, calculating the average electric quantity consumption according to the electric quantity consumption of the mobile terminal in each period, and calculating the current electric quantity consumption speed of the mobile terminal according to the average electric quantity consumption and the preset period length.
optionally, the power consumption of the mobile terminal in a partial period may also be selected, an average power consumption is calculated according to the power consumption of the mobile terminal in the selected partial period, and the current power consumption speed of the mobile terminal is calculated according to the average power consumption and the preset period length.
for example, an average power consumption amount of 0.5% is calculated based on 0.3% of the power consumption amount of the mobile terminal in the first period, 0.5% of the power consumption amount of the mobile terminal in the second period, and 0.7% of the power consumption amount of the mobile terminal in the third period, and a current power consumption rate of the mobile terminal is calculated to be 0.05% per second based on the average power consumption amount of 0.5% and a preset period length of 10 seconds. Or selecting a second period and a third period, calculating the average electric quantity consumption of 0.6% according to the selected 0.5% electric quantity consumption of the mobile terminal in the second period and 0.7% electric quantity consumption of the mobile terminal in the third period, and calculating the current electric quantity consumption speed of the mobile terminal to be 0.06% per second according to the average electric quantity consumption of 0.6% and the preset period length of 10 seconds.
among them, it should be noted that: and executing subsequent steps when the current residual capacity of the battery and the current capacity consumption speed of the mobile terminal are acquired in each period.
Step 203: and calculating the remaining time of the mobile terminal from shutdown according to the current remaining power of the battery and the current power consumption speed of the mobile terminal.
the mobile terminal automatically shuts down when the remaining battery capacity reaches a preset value, wherein the preset value can be a default value or a value set by a user in advance.
the method comprises the following steps: and calculating an electric quantity difference value according to the current residual electric quantity of the battery and the preset value, and calculating the residual time of the mobile terminal from shutdown according to the electric quantity difference value and the current electric quantity consumption speed of the mobile terminal.
for example, assuming that the current power consumption rate of the mobile terminal is 0.05% per second, the remaining time of the mobile terminal from power-off is calculated to be 170 seconds according to the current remaining power of the battery of 8.5% in the third period and the current power consumption rate of the mobile terminal is 0.05% per second.
Step 204: the remaining time is displayed.
a countdown display according to the remaining time may be performed at a preset position on the screen of the mobile terminal. The preset position may be a position of the top, the bottom, or both sides of the screen of the mobile terminal.
The preset countdown time threshold value can be set in advance, can be a default numerical value, and can also be set by a user according to the requirement of the user. And when the countdown time is less than or equal to a preset countdown time threshold value, displaying the countdown time.
In this embodiment, the preset time threshold may not be set, so that when the remaining capacity of the battery decreases to the preset capacity threshold, the countdown display is performed according to the above steps 202 to 204.
Since the above steps 202 to 204 are performed at each cycle, when the obtained remaining time is different from the currently displayed countdown time, the countdown time display is performed again according to the remaining time.
In step 205: and acquiring the working frequency corresponding to the preset electric quantity consumption speed according to the preset electric quantity consumption speed, and controlling the working frequency of the mobile terminal not to exceed the acquired working frequency.
the mobile terminal comprises an electric quantity management module, and the electric quantity management module is used for managing the electric quantity of the battery in the working process of the mobile terminal. The power management module may monitor a power consumption rate of the mobile terminal with respect to the battery power when the mobile terminal operates at different operating frequencies, and may store the power consumption rates at different operating frequencies and different operating frequencies in a correspondence relationship between the operating frequency and a power message rate, where the operating frequency includes a CPU (central Processing Unit) operating frequency and a GPU (Graphics Processing Unit) operating frequency.
the method comprises the following steps: according to the preset electric quantity consumption speed, acquiring corresponding working frequency from the corresponding relation between the working frequency and the electric quantity consumption speed, controlling the working frequency of the CPU of the mobile terminal not to exceed the working frequency of the CPU included in the acquired working frequency, and controlling the working frequency of the GPU of the mobile terminal not to exceed the working frequency of the GPU included in the acquired working frequency. Therefore, the remaining time of the mobile terminal from power-off can be prolonged, so that the user has enough time to finish the ending work.
In order to prolong the remaining time of the mobile terminal from power off, the power consumption speed of the screen of the mobile terminal can be reduced. Specifically, the method can be implemented in any one or more of the following two ways, including:
Firstly, the current display brightness of the screen of the mobile terminal is reduced.
a brightness threshold may be preset, where the brightness threshold may be the lowest brightness of the screen of the mobile terminal or slightly greater than the lowest brightness, and if the current display brightness of the screen of the mobile terminal is greater than the preset brightness threshold, the current display brightness of the screen of the mobile terminal is adjusted to be less than or equal to the preset brightness threshold.
And secondly, reducing the current contrast of the screen of the mobile terminal.
A contrast threshold may be preset, and if the current contrast of the mobile terminal screen is greater than the preset contrast threshold, the current contrast of the mobile terminal screen is adjusted to be less than or equal to the preset contrast threshold.
In the embodiment of the invention, because the current residual electric quantity of the battery of the mobile terminal and the current electric quantity consumption speed of the mobile terminal to the battery are obtained, the residual time of the mobile terminal from shutdown is calculated according to the current residual electric quantity and the current electric quantity consumption speed; and performing countdown display according to the remaining time, so that the user knows the remaining time when the mobile terminal is powered off currently, the user can reasonably arrange that the user is performing service ending work at the mobile terminal, and data loss is avoided.
