Background application cleaning method and device, storage medium and terminal equipment

Embodiments of the invention provide a background application cleaning method and apparatus, a storage medium and a terminal device. The method comprises the steps of running a pre-created application identification program on a to-be-tested terminal; when the application recognition program recognizes that the target application exists in the to-be-tested terminal, background cleaning operation is executed on the target application; obtaining a power consumption monitoring log of the to-be-tested terminal in a real-time updating state, and extracting result index data in the power consumption monitoring log; if the result index data shows that the power consumption of the to-be-tested terminal is abnormal, judging whether the result index data is associated with a target application or not; and performing performance updating operation on the application identification program. According to the embodiment of the invention, whether the background application running on the terminal equipment is abnormal or no
