Embodiments of the present application provide a power consumption anomaly prompting method, a server, and a terminal, for accurately identifying an anomaly in power consumption of an application and reducing the misjudgment rate on anomalies in power consumption of an application. The method in the embodiments of the present application comprises that: a server receives report information sent by a terminal, the report information comprising first application running information of the terminal and first application power consumption quantity of the terminal, wherein the first application is any application on the terminal; the server determines, according to the report information, whether the power consumption of the first application is abnormal; when the power consumption of the first application of the terminal is determined as abnormal, the server sends prompt information to the terminal, the prompt information indicating an anomaly in the power consumption of the first application of the terminal, and the running information at least comprising at least one of foreground running duration, background running duration, download traffic, a multimedia file download format, and multimedia file downloads.
