The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

The terms "first", "second", "third", etc. (if any) in the description and claims of the present invention and the above drawings are used to distinguish similar objects and not necessarily to describe a specific order or sequentially. It should be understood that the items so described are interchangeable under appropriate circumstances. Furthermore, the terms "comprising" and "having", as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, a method comprising a series of steps, or a device, a terminal, a system comprising a series of modules or units are not necessarily limited to those steps or modules or units clearly listed, and may also include steps or units not clearly listed. A module or unit may also include other steps or modules or units inherent to these processes, methods, apparatuses, terminals or systems.

Embodiments of the present invention provide a power display method, device, and terminal, which will be described in detail below.

A power display method, which can be applied to a terminal. The terminal includes a battery and a memory. The terminal may be a device such as a smart phone or a tablet computer.

As shown in FIG. 1, the power display method may include the following steps:

S110. Write the first electric quantity of the battery into the memory.

In practical applications, the terminal can detect the remaining power of the battery in real time, and periodically write the current remaining power of the battery into the memory. For example, the terminal may update the power information written in the memory every minute. The remaining power is the first power.

The memory may be a non-volatile memory, that is, the data stored in the memory will not be lost after the memory is powered off.

The remaining capacity can be the actual remaining capacity of the battery (for example, 2000mAh), or the percentage of the actual remaining capacity of the battery to the total capacity of the battery (for example, 80%), or a numerator in the percentage (for example, when the percentage is 80%) , take the value 80).

S120, after the terminal restarts, acquire the current second electric quantity of the battery.

In practical applications, when the terminal is restarted, the current battery power is obtained. The current battery level is the second level.

Referring to FIG. 2 at the same time, in some embodiments, after the terminal is restarted, obtaining the current second power level of the battery may include the following steps:

S121, after the terminal restarts, obtain the current voltage of the battery;

S122. Acquire the current second electrical quantity of the battery according to the current voltage and a preset mapping relationship, where the preset mapping relationship is a mapping relationship between the battery voltage and the battery electrical quantity.

In practical applications, the terminal may pre-store the mapping relationship between the battery voltage and the battery power. The mapping relationship can be a linear relationship or a nonlinear relationship. The mapping relationship can be established by experimentally detecting the correspondence between the voltage and the remaining power of multiple batteries of the same specification. For example, when the battery voltage is 3.9V, the corresponding remaining battery capacity is 70%; when the battery voltage is 3.8V, the corresponding remaining battery capacity is 65%.

After the terminal restarts, the terminal can detect the current voltage of the battery. Then the current remaining battery capacity is obtained according to the detected battery voltage and the pre-stored mapping relationship. For example, when the terminal detects that the current voltage of the battery is 3.8V, it can determine that the current remaining power of the battery is 65%.

S130, judging whether the absolute value of the difference between the first electric quantity and the second electric quantity is smaller than a preset threshold, so as to obtain a judgment result.

In practical applications, after the terminal acquires the current second electric quantity of the battery, it compares the first electric quantity stored in the memory (represented by soc1 hereinafter) with the second electric quantity (represented by soc2 hereinafter). During the comparison process, it can be judged whether the absolute value of the difference between soc1 and soc2 is smaller than a preset threshold (hereinafter denoted by K), that is, judge whether |soc1-soc2|<K holds true, and obtain the judgment result. The preset threshold K may be a value pre-stored in the terminal, for example, K may take a value of 10%.

In some embodiments, before the step of determining whether the absolute value of the difference between the first electric quantity and the second electric quantity is less than a preset threshold to obtain the judgment result, the electric quantity display method may further include the following steps:

S150. Obtain the first electric quantity from the memory to obtain the obtained first electric quantity;

S160. Determine whether the acquired first electric quantity satisfies a preset condition.

In practical applications, after the terminal obtains the current second electric quantity of the battery, it retrieves the stored first electric quantity from the memory to obtain the obtained first electric quantity.

Theoretically, the obtained first electric quantity should be the same as the first electric quantity stored in the memory. However, due to possible objective factors such as system failure and memory failure, the first power quantity acquired by the terminal may also be different from the first power quantity stored in the memory.

After the terminal obtains the first electric quantity, it judges whether the obtained first electric quantity satisfies a preset condition. Wherein, the preset condition may be a condition for checking whether the obtained first electric quantity (represented by soc1 ₀ hereinafter) is normal. For example, when the first electric quantity is a percentage, the preset condition may be whether 0<soc1 ₀ <100% is established. When 0<soc1 ₀ <100% is established, the judgment result is that the obtained first power meets the preset condition, and then step S130 is executed; when 0<soc1 ₀ <100% is not established, the judgment result is that the obtained first power does not satisfy Preset conditions, the terminal can then terminate the process.

S140, displaying the current electric quantity of the battery according to the determination result.

In practical application, after the terminal obtains the judgment result of whether the absolute value of the difference between the first electric quantity and the second electric quantity is less than a preset threshold, the terminal displays the current electric quantity of the battery according to the judgment result. A schematic diagram of displaying battery power on the terminal is shown in FIG. 3 .

In some embodiments, displaying the current charge of the battery according to the judgment result may include the following steps:

S141, when the judgment is yes, determine the first electric quantity as the current electric quantity;

S142, displaying the current electric quantity.

In practical application, when the judgment result in S130 is that |soc1-soc2|<K is established, the terminal determines the first electric quantity as the current electric quantity of the battery, and displays the current electric quantity. For example, when the value of K is 10%, and |soc1-soc2|=5%, the terminal determines the first electric quantity as the current electric quantity, and displays the current electric quantity.

In some embodiments, displaying the current charge of the battery according to the judgment result may include the following steps:

S143, when the judgment is no, determine the second electric quantity as the current electric quantity;

S144, displaying the current electric quantity.

In practical applications, when the judgment result in S130 is that |soc1-soc2|<K does not hold, the terminal determines the second power level as the current power level of the battery, and displays the current power level. For example, when the value of K is 10%, and |soc1-soc2|=15%, the terminal determines the second electric quantity as the current electric quantity, and displays the current electric quantity.

In some embodiments, after determining the first electric quantity as the current electric quantity and displaying the current electric quantity, the electric quantity display method may further include the following steps:

S170, acquiring a preset power adjustment amount and a preset power adjustment time interval;

S180. Adjust the current power according to the power adjustment amount and the power adjustment time interval, so that the current power is equal to the second power.

In practical applications, the startup process of the terminal consumes a part of power. Therefore, after the terminal is restarted, the second electric quantity obtained by the terminal is the actual electric quantity of the battery at this time, but the electric quantity displayed by the terminal, that is, the first electric quantity is not the actual electric quantity of the battery at this time. In order to make the power displayed on the terminal consistent with the actual power of the battery, it is necessary to adjust the power displayed on the terminal. This adjustment can be adjusted up or down.

The terminal determines the first electric quantity (soc1) as the current electric quantity, and after displaying the current electric quantity, obtains the preset electric quantity adjustment amount and the preset electric quantity adjustment time interval, and adjusts the current electric quantity according to the electric quantity adjustment amount and the electric quantity adjustment time interval Adjustment is made so that the current electric quantity is equal to the second electric quantity (soc2).

Wherein, the power adjustment amount may be an adjustment range each time, and the power adjustment time interval may be a period of time. For example, when the displayed power is a percentage, the power adjustment amount can be 1% of the total battery capacity, and the preset time interval can be 1 minute. That is, when soc1 is greater than soc2, the displayed battery capacity is decreased by 1% every minute; when soc1 is smaller than soc2, the displayed battery capacity is increased by 1% every minute. When the battery power displayed on the terminal is equal to the second power (soc2), the adjustment ends.

During specific implementation, the present invention is not limited by the execution order of the described steps, and some steps may be performed in other orders or simultaneously if no conflict arises.

It can be seen from the above that the power display method provided by the embodiment of the present invention writes the first power level of the battery into the memory; when the terminal is restarted, obtains the current second power level of the battery; judges the first power level and the second power level Whether the absolute value of the difference is less than the preset threshold value is used to obtain the judgment result; the current power capacity of the battery is displayed according to the judgment result. This solution judges whether the absolute value of the difference between the first power and the second power is less than the preset threshold after the terminal is restarted, and displays the current power of the battery according to the judgment result, which can reduce the battery power jump before and after the terminal restarts.
