Battery life

Note: GPS 1 (AT&T device) guidance is available here 

The battery can last up to 24 hours with continuous monitoring. The battery life can be impacted by poor cellular reception, being in unnamed locations, long transits, and use of Runner Mode and calls.
 
Note: GPS devices typically have long battery life in standby mode. We do not support this mode since it is not effective for keeping the child safe as querying the GPS for its location after waking up from standby is not reliable. The location is highly inaccurate in this mode. AngelSense patent pending power management algorithms assure longer battery life with continuous monitoring.

Why Your Child with Autism Needs a BIGGER GPS Device 

Proactive alerts to routine deviations and providing consistent location updates in poor GPS and cellular conditions are indispensable features. Supporting these capabilities require enough power to sustain the device and can only be achieved with larger battery size and an equally accommodating device.
