Embodiment 1
[0037] like Figure 4 , this embodiment is a single CPU solution.
[0038] 1. When the main power button is pressed to turn on the machine, if the CPU detects that there is an electrical connection to the auxiliary machine, the CPU controls the power supply control circuit to make the CPU work in the low-power auxiliary machine working mode, open the public circuit part, and turn on the auxiliary machine power supply circuit At this time, the mobile phone only has the most basic low power consumption functions such as calls and short messages, because most of the power consumption functions of the smart phone are not powered at this time, so as to achieve the purpose of ultra-long standby. If the CPU does not detect that there is an electrical connection of the auxiliary machine, the CPU controls the power control circuit to make the CPU work in the touch screen mode, open the common circuit part, and open the host power supply circuit. At this time, the mobile phone only has ...
Embodiment 2
[0042] like Figure 5 , this embodiment is a dual-CPU solution.
[0043] 1. When pressing the main power button to turn on the machine, if the low-power sub-CPU detects that a mobile phone sub-machine is plugged in, the low-power sub-CPU controls the power supply control circuit, turns on the public circuit, and turns on the power supply circuit of the sub-machine. At this time, the mobile phone It only has the most basic low power consumption functions such as calls and short messages, because most of the power consumption functions of the smart phone are not powered at this time, so as to achieve the purpose of super long standby time.
[0044] 2. When the auxiliary power button is pressed, the main CPU controls the power control circuit, turns on the public circuit, and turns on the host power supply circuit. At this time, the mobile phone only has the function of a smart phone.
[0045] 3. When the main power button is pressed and the low-power sub-CPU does not detect...
