Abstract
The invention discloses a method for prompting mobile phone talk time under a state of lacking electric quantity of mobile phone battery. In the method, the remaining electric quantity of the battery, backlight power consumption of corresponding power of backlight brightness and the power consumption required by the talk can be calculated mainly by obtaining the voltage of the current battery, the brightness of the current LCD backlight, the light time of the backlight and obtained intensity of transmitted signals of the current environment during dialling; the remaining talk time of mobile phone under the current conditions is calculated; and the talk time is displayed on a display screen, so that a user can intuitively and clearly know the remaining talk time and carry out reasonable talk arrangements so as to avoid transmitting important information in the remaining time.
Description
Technical field:
The present invention relates to the method for a kind of prompting mobile telephone set air time, particularly a kind of under the not enough state of cell-phone battery electric-charge quantity prompting mobile telephone set residue conversation time method.
Background technology:
Mobile phone is as communication tool commonly used, life with people is closely bound up, and there are much relations the mobile phone communication time with cell-phone battery electric-charge quantity, especially running into emergency, and under the state of cell-phone battery electric-charge quantity deficiency, need clearly know the concrete air time, in the concrete time, important urgent delivery of content gone out guaranteeing, avoid occurring suddenly in the communication process mobile phone and do not have electric situation.
Summary of the invention:
For this reason, purpose of the present invention then be to provide a kind of under the not enough state of cell-phone battery electric-charge quantity prompting mobile telephone set residue conversation time method, to guarantee that the user is under the situation of cell-phone battery electric-charge quantity deficiency, can know and know the remaining air time, to reach the purpose that within a certain period of time information is passed.
For achieving the above object, the present invention mainly adopts following technical scheme:
The method of prompting mobile telephone set air time under the not enough state of a kind of cell-phone battery electric-charge quantity, specifically comprise step: when subscriber dialing, the cell phone mainboard detection module obtains the magnitude of voltage information A 1 of current phone battery; The mainboard detection module sends to the mobile phone cpu chip with magnitude of voltage information A 1, and the battery electric quantity value that cpu chip is corresponding with the standard voltage value in being stored in mobile phone with magnitude of voltage information A 1 compares, and draws the pairing battery electric quantity value of this magnitude of voltage A1 P1; When the user opens LCD when backlight, the cell phone mainboard detection module obtains current LCD brightness degree B1 backlight, and this brightness degree B1 sent to the mobile phone cpu chip, the electric weight power consumption parameter that cpu chip is corresponding with brightness degree in being stored in mobile phone with brightness degree B1 compares, and obtains the electric weight power consumption P2 under this brightness degree; When subscriber dialing, the cell phone mainboard detection module obtains current demand signal strength grade C1, and this signal strength scale C1 sent to the mobile phone cpu chip, the electric weight power consumption parameter that cpu chip is corresponding with the signal strength scale in being stored in mobile phone with signal strength scale C1 compares, and obtains the electric weight power consumption P3 under this signal strength scale; Pass through formula: the air time=power consumption of [remaining battery electric quantity-(the power consumption * backlight lightening time of consuming backlight)] ÷ conversation, calculate the remaining air time under battery electric quantity P1 state; CPU sends to display screen with the air time that calculates by the handset displays module, shows on display screen.
The present invention calculates detected remaining battery electric quantity, the power consumption that consumes backlight and conversation power consumption by mobile phone CPU, obtain the residue air time under current battery electric quantity and backlight power consumption, and should on mobile phone display screen, show the time, make the user can intuitively clearly know the remaining air time, thereby reasonably converse arrangement, avoided important information in remaining time, to pass.
Description of drawings:
Fig. 1 is a flow chart of the present invention.
Embodiment:
Core concept of the present invention is: obtain the voltage (unit is mV) of current battery by the mobile phone detection module, and according to the discharge curve of battery, calculate remaining battery electric quantity (unit is mAH) by CPU; By obtaining current LCD brightness backlight and backlight lightening time, the parameter according to the corresponding power of the different backlight illuminations of prior test obtains the power consumption that consumes backlight (unit is mA); Obtain the intensity that transmits under the current environment during dialing, according to the parameter of corresponding transmitting power under the prior test unlike signal intensity, the required power consumption that obtains conversing (unit is mA).When subscriber dialing, mobile phone CPU can obtain the current magnitude of voltage of system, LCD brightness degree, LCD lights the time, parameters such as signal strength signal intensity, the parameter list that obtains according to prior test, converse battery dump energy, LCD power consumption, the conversation power consumption, calculate by following formula then:
The air time=power consumption of (remaining battery electric quantity-(the power consumption * backlight lightening time of consuming backlight)) ÷ conversation
For setting forth core concept of the present invention and purpose of the present invention, the present invention is described in further details below in conjunction with the drawings and specific embodiments.
