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.
