Problems solved by technology

However, since the power of the backup battery 102 is very low, when the operation time for the user to replace the main battery 101 is relatively long, and the power consumption of the current application program is large, the power of the backup battery 102 is easily exhausted quickly, resulting in the replacement of the backup battery 102. The voltage drops seriously, and then the voltage is too low, causing problems such as automatic shutdown or power failure of the mobile phone system

Embodiment Construction

[0020] see figure 2 , figure 2 It is a structural schematic diagram of an embodiment of the mobile phone of the present invention. Such as figure 2 As shown, the mobile phone 200 of this embodiment includes a backup battery 201, a first P-MOS tube 202, a second P-MOS tube 203, a main battery 204, a magnetic device 205, a power management unit 206, a magnetic induction device 207, and a baseband processing chip 208 , memory 209 and input device 210 .

[0021] In this embodiment, the baseband processing chip 208 is connected to the power management unit 206 , the memory 209 and the input device 210 . The backup battery 201 and the main battery 204 are connected to the power management unit 206 through the first P-MOS transistor 202 and the second P-MOS transistor 203 respectively, and supply power to the power management unit 206 . Specifically, when the main battery 204 is inserted into the mobile phone 200, the main battery 204 is mainly responsible for powering the pow...

Abstract

The invention discloses a cellphone and a control method thereof. The cellphone comprises a main battery and a stand-by battery. The stand-by battery is used for supplying power for the cellphone when the main battery is removed, a magnetic device is arranged on the main battery, and a magnetic induction device is arranged on a circuit board of the cellphone. The control method includes detecting intensity of magnetic fields generated by the magnetic device by utilizing the magnetic induction device; outputting a first level signal when the intensity of the magnetic fields is lower than a preset threshold value; and responding the first level signal to control the cellphone to enter a sleep state. By the control method of the cellphone, removal of the main battery can be inducted automatically, the cellphone is controlled to enter the sleep state when the main battery is removed, so that sudden power-off or power-failure of the cellphone caused by fast consumption of the stand-by battery can be avoid effectively.

Description

technical field [0001] The invention relates to the communication field, in particular to a mobile phone and a control method thereof. Background technique [0002] Such as figure 1 As shown, many smart phones currently design a main battery 101 and a backup battery 102 in the power supply system of the mobile phone. unit 105, and supply power to the power management unit 105, and the power management unit 105 converts the voltage of the main battery 101 or the backup battery 102 into the voltage required by each power receiving unit. When the user replaces the main battery 101 , since the backup battery 102 can continue to supply power to the power management unit 105 , the application programs currently running in the system can continue to be maintained. [0003] In the above design, although the user generally replaces the main battery 101 , the currently running application programs of the system can continue to be maintained. However, since the power of the backup b...
