Power supplying method, power supplying system, and electronic device

Abstract

The present disclosure discloses a power supplying method, a power supplying system, and an electronic device to address the technical problems in the related art that the structure of an electronic device is complex, thereby achieving the technical effect that the internal structure of an electronic device is simplified and the cost for manufacturing the electronic device is reduced. The method comprises: detecting and acquiring current voltage of a power supplying battery in an electronic device as a first voltage if the power supplying battery is in a first power supplying state where a first operational circuit comprising a Real-Time Clock (RTC) and a second operational circuit are supplied with power, wherein the power supplying battery is connected to the first operational circuit and the second operational circuit via a regulator, and wherein the second operational circuit is a power-on circuit comprising a power switch; determining whether the first voltage is lower than a preset voltage to acquire a determination result; and controlling the power supplying battery to switch from the first power supplying state to a second power supplying state where only the first operational circuit is supplied with power if the determination result is yes.
