By default, SMS Tracker attempts to track the phone’s location using the GPS services. This feature consumes a lot of power and you should consider turning it off. If you are running SMS Tracker 4.004 or higher, you can turn this feature off if location tracking isn’t something you need to have ON all the time. To turn this off, go to the Settings page and click the “Edit this phone” link. Toggle the setting for “Enable GPS Polling” to off.
