Embodiment 1
As shown in Figure 5, the mobile phone of embodiment 1 has radio frequency unit, baseband circuit, central processing unit (CPU), FLASH, RAM, LCD, keyboard and mobile phone power-saving device.Wherein, LCD display and keyboard are by CPU and mobile phone power-saving device exchange control or shows signal.FLASH, RAM use for mobile phone power-saving device or other correlation function by the CPU managing access to data.
Select the part selected cell of powering by keyboard in cell phone system, the power supply selected cell is transferred to LCD display with shows signal and shows, selects or multinomial power supply the in the middle of the partial function by keyboard in the part power supply unit.
As shown in Figure 8, LCD display has shown selective partial function option, and these partial functions comprise: call function (comprising address list), SMS, vibration function of cell phone, Bluetooth function, USB function, partial function options such as GPS function.The display screen right side has a moving slider, can choose selected partial function option by the up-down adjustment of this moving slider, so that under energy-saving mode, only is selected part cell-phone function power supply.
Selected partial function is in the present embodiment: call function and SMS." determining " button of screen below is finished the selection of part function of supplying power is confirmed.
The setting of electric weight threshold values can unify to set before mobile phone dispatches from the factory, and also can be set up on their own by the user in mobile phone.The operational formula of electric weight threshold values is:
The stand-by time of the unit interval power consumption * expectation of electric weight threshold values=mobile phone partial function
Therefore, as long as the stand-by time of the expectation when the unit interval power consumption of input handset partial function and this partial function work independently just can obtain corresponding electric weight threshold values.
The dump energy of the real-time detection of handset battery of dump energy detecting unit of battery saving arrangement, electric weight threshold values comparing unit compares detected dump energy and preset electric quantity threshold values, if described dump energy is lower than described electric weight threshold values, the mobile phone power-saving device then triggers the power supply switch unit battery of mobile phone only is the call function of mobile phone and SMS power supply from switching to for mobile phone bulk supply.Also call function power supply unit and the power supply of SMS power supply unit that promptly only sets for present embodiment.
Shown in Fig. 9 A, the power supply switch unit sends to trigger command closes non-call function unit, and brightness reduces the unit, dominant frequency reduces the unit, and volume reduces the unit, and make said units carry out associative operation: the non-call function of mobile phone is closed in non-call function unit, non-call function comprises the WIFI function, Bluetooth function, USB function, GPS function, multi-media player function, vibration function of cell phone, basket tooth function, the USB function, the GPS function, WIFI function, sound-recording function and reception broadcast capability etc.; Brightness reduces the unit and reduces the LCD display brightness of mobile phone to lowest visible brightness; Dominant frequency reduces the unit to be adjusted the mobile phone dominant frequency, makes CPU frequency≤50MHz; Volume reduces the unit and reduces mobile phone volume to the minimal volume value.
Shown in Fig. 9 B, the mobile phone power-saving device calls the partial pixel that pixel drive unit is lighted the LCD of mobile phone display screen, pixel drive unit makes the regional area of part display pixel on the LCD of mobile phone display screen of being lighted form a viewing area, and this viewing area only shows by power supply switch unit default call function and SMS and power supply switch unit function.
As shown in Figure 5, the mobile phone of embodiment 2 has radio frequency unit, baseband circuit, central processing unit, FLASH, RAM, LCD and dump energy detecting unit, electric weight threshold values comparing unit, power supply switch unit, pixel switch unit, non-call function closing unit, brightness reduction unit, dominant frequency reduction unit, and volume reduces the unit.
As shown in figure 10, the user selects the partial function powered by the part selected cell of powering.Mobile phone is set in the present embodiment switches to when powering, only support call function and the SMS and the USB function of mobile phone into partial function.
The user is provided with default electric weight threshold values by the power supply switch unit, and this electric weight threshold values draws by following formula: the stand-by time of the unit interval power consumption * expectation of electric weight threshold values=described mobile phone partial function.
The dump energy of the real-time detection of handset battery of mobile phone, detected dump energy and preset electric quantity threshold values are compared, if described dump energy is lower than described electric weight threshold values, then make described battery of mobile phone from switching to for mobile phone bulk supply only for supporting call function, SMS and the USB function of mobile phone.
Close the non-call function of mobile phone simultaneously, comprise the WIFI function, Bluetooth function, the function that GPS function, multi-media player function etc. are not chosen at interface shown in Figure 8; The LCD display brightness that reduces mobile phone is to lowest visible brightness; The mobile phone dominant frequency is adjusted to minimum dominant frequency, for example makes CPU frequency≤50MHz; The volume that reduces mobile phone is to the minimal volume value.
As shown in figure 11, after finishing above-mentioned steps, the switch mobile phone display screen, light the partial pixel of handset displays screen by pixel drive unit, make the regional area of part display pixel on mobile phone display screen of being lighted form a viewing area, this viewing area only is presented at the power supply switch unit call function, SMS, USB function and the power supply switch unit function that sets in the interface is set.
In sum, mobile phone power-saving method of the present invention by closing peripheral non-call function module, reduces the mobile phone dominant frequency, and modes such as display brightness and minimizing viewing area reduce the power consumption of mobile phone, have increased the stand-by time of mobile phone.
Above-described embodiment; purpose of the present invention, technical scheme and beneficial effect are further described; institute is understood that; the above only is the specific embodiment of the present invention; and be not intended to limit the scope of the invention; within the spirit and principles in the present invention all, any modification of being made, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
