Disclosed are a power management system and a method for mobile applications using location based services. Generally described, the system and method manages power of a wireless device by adjusting the sampling rate of mobile applications that use location based services. In one illustrative embodiment, the power can be managed by establishing a schedule. The schedule can include settings such as a start time, end time, interval, and duration. These settings can be used to establish a window of time whereby multiple location samplings can take place. The schedule can minimize the user's involvement on a continual basis by allowing manual and automatic scheduling. The power manager can include, but is not limited to, three features to provide better power management for the wireless device. These can include scheduling for location sampling, automatic and learned scheduling, and frequency and duration dynamic modification. Through the power manager, the power supply on the wireless device can be maximized.
