Patent ID: 11860705
Assignee: VIVO MOBILE COMMUNICATION CO., LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 6:
7. An electronic device, comprising: hidden function key circuits and a processor, wherein
the hidden function key circuits comprise: a sub-control circuit, and a plurality of key sensors electrically connected to the sub-control circuit, an amplification filter circuit, and an ADC sampling circuit,
the sub-control circuit is configured to:
obtain a current state of the electronic device transmitted by the processor, wherein the current state comprises: a shutdown state, a standby state, and a use state;
determine a target integration time of the ADC sampling circuit based on the current state; and
adjust an integration time of the ADC sampling circuit to the target integration time, and adjust a power-on time of the hidden function key based on the adjusted integration time to control actual power consumption of the electronic device, wherein the integration time is positively correlated with the power-on time.
