Their concern isn’t wholly unfounded. It has been shown that GPS and geofencing apps consume battery power throughout the day.
In a recent study, a GPS app depleted battery life by 13% in an area with good signal strength and 38% in an area with weak signal strength.
The two main reasons for this additional battery drain are that the apps must determine your location and then periodically refresh it.
1. Determining location
GPS tracking technology uses satellites to determine a contractor’s location, which is slow compared to fiber optics. In an area with a good network signal, this usually takes an average of 12-30 seconds. However, this can take up to 12 minutes in an area with poor signal.
During this time, your employee’s phone is active, consuming battery power, even if their screen is off. That means the longer it takes to find and upload a current location, the more battery the app will drain trying to complete its function.
2. Refreshing location
Geofencing apps regularly refresh employees' location to determine when they enter or exit defined areas. This constant refreshing can prevent a phone from entering a prolonged sleep period, making it unable to conserve battery life.
However, the app must do this periodically to ensure accurate data. So, there must be a balance between overworking the processing systems and risking slow or inaccurate tracking data.
Add in any screen time checking the app, weak signal, regular changes in location, and an old battery, and you could have a battery-sapping location-tracking app. But that doesn’t have to be the case.
