The present invention provides a method and an apparatus for adjusting a voltage carried on a phone set, and a system. The adjustment method includes: detecting, by an adjustment apparatus, a working state of each phone set in N phone sets, where N is an integer greater than 1 (S101); determining, by the adjustment apparatus according to a preset mapping relationship, a required voltage that corresponds to the working state of each phone set (S102); using, by the adjustment apparatus, a largest voltage value in the N required voltages as a target voltage, and instructing a power supply to adjust an output voltage to the target voltage (S103); and adjusting, by the adjustment apparatus according to the target voltage, a voltage carried on each phone set to the required voltage that corresponds to the working state of each phone set (S104). By means of the present invention, a quantity of power supplies and costs can be reduced. |
