The invention discloses a user behavior analysis-based low-power scheme and system of an intelligent Bluetooth remote controller. The method comprises the steps of obtaining one-time power consumption through performing statistics analysis on key pressing behaviors, used for operating a remote controller device, of a user by utilizing a two-way communication technology of the Bluetooth remote controller; performing statistics on the power consumption of the key pressing behaviors of the user in a single cycle; comparing the power consumption in multiple cycles to obtain average power consumption per cycle; performing calculation according to the average power consumption per cycle of the remote controller to obtain the number of residual power usage days of the remote controller; displaying the number of the residual power usage days on a main control device to remind the user; and meanwhile, setting power-saving threshold time, and when the number of the residual power usage days of the remote controller is smaller than the power-saving threshold, entering a power-saving mode. Therefore, the problems in power pre-warning reminding and power consumption reduction of the remote controller are solved.
