1. A method for detecting device power comprising:
detecting, by a monitoring terminal, power information of a monitored device;
setting, by the monitoring terminal, a monitoring time interval according to the power information of the monitored device and a preset time interval; and
detecting, by the monitoring terminal after setting the monitoring time interval, the power information of the monitored device according to the monitoring time interval;
wherein, prior to setting the monitoring time interval, the power information of the monitored device is detected at two consecutive times;
wherein setting the monitoring time interval further comprises:
calculating a power decline rate of the monitored device according to the power information of the monitored device detected at the two consecutive times and the preset time interval;
comparing the calculated power decline rate to a preset power decline rate; and
setting the monitoring time interval to be greater than the preset time interval in response to the calculated power decline rate being less than the preset power decline rate, or setting the monitoring time interval to be less than the preset time interval in response to the calculated power decline rate being greater than the preset power decline rate.
