Physical Activity Setting
Allowing access to the physical activity setting will improve battery life. Physical activity uses the accelerometer to determine motion instead of constantly looking for GPS location data changes to determine when you are actually moving. The less activity by the GPS sensor in your phone, the longer your battery will last.
You can enable or disable this setting at anytime but it is recommended to keep it on, especially during a disaster where charing may not be readily available.
