The invention provides a charge-discharge circuit, a mobile terminal and a battery charge-discharge control method, relates to the technical field of electronics and solves the problem of singleness of the existing battery charge-discharge mode. The charge-discharge circuit comprises a charge input terminal, a discharge output terminal, a grounding terminal, at least two batteries and multiple switches, wherein the multiple switches are connected to a connecting circuit of the at least two batteries, the charge input terminal, the discharge output terminal and the grounding terminal; the charge-discharge circuit forms a series-connection charge circuit, a parallel-connection charge circuit, an independent charge circuit, a series-connection discharge circuit, a parallel-connection discharge circuit or an independent discharge circuit by controlling connection or disconnection of the multiple switches. According to the scheme, the charge-discharge mode is enriched, compatibility with a charger is improved, the problems such as high charge heat, high discharge loss, high requirements for interfaces and channels and the like of a single charge-discharge mode can be solved, and charge-discharge experience is improved.
