Method for Reducing Power Consumption of Location Based Applications Running on Mobile Devices

A method of conserving battery power in a device running a location aware application and being carried by a user, comprising:

• the location aware application using sensor or receiver information to determine locomotion characteristics of the user;
• in a first mode in which the locomotion characteristics are presumed accurate, performing limited data gathering of sensor or receiver information;
• and
• in a second mode, performing more extensive data gathering of sensor or receiver information for purposes of updating the locomotion characteristics.

A non-transitory computer-readable medium for conserving battery power in a device running a location aware application and being carried by a user, comprising instructions for:

• causing the location aware application using sensor or receiver information to determine locomotion characteristics of the user;
• in a first mode in which the locomotion characteristics are presumed accurate, performing limited data gathering of sensor or receiver information;
• and
• in a second mode, performing more extensive data gathering of sensor or receiver information for purposes of updating the locomotion characteristics.

A device running a location aware application and being carried by a user, comprising:

• one or more sensors or receivers for determining location information;
• a processor for running the location aware application, the location aware application being configured to:
• use sensor or receiver information to determine locomotion characteristics of the user;
• in a first mode in which the locomotion characteristics are presumed accurate, perform limited data gathering of sensor or receiver information;
• and
• in a second mode, perform more extensive data gathering of sensor or receiver information for purposes of updating the locomotion characteristics.
