Battery Life

Battery Life is the top concern for users- and for good reason! Below is a breakdown of proper charging and the 3 factors that most affect battery life.

On average, customers see 12-16 hours of battery life from a full charge. As you will read below, use case and environmental factors will determine if you will see longer or shorter battery life.


The PF+ utilizes a rechargeable lithium-ion battery. These batteries are designed to be charged to 100% and then let drain down as much as possible before being charged again. This will aid in the overall life of your battery. We recommend setting a low battery alert at 20% and not leaving plugged in to charge for more than 24 hours at a time. 

When charging via a computer, please make sure the computer is plugged in as well. This will provide a trickle charge and takes around 3-4 hours to reach a full battery. 

When charging via a wall outlet or portable battery, please make sure it is NOT a rapid charger cube. The charger cube should NOT have an output higher than 5V / 1A. Charging with a rapid charger can lead to overheating, internal device damage, and shortened battery life. 

When initially plugging in to charge, you should see a solid blue light appear. This will eventually turn off but does not indicate a full charge. You can always wiggle your device around on the charger to get an updated locate and battery level.

3 Factors Affecting Battery Life

- Frequency: This relates not just to Power Mode but how often Track Mode and SOS are enacted. The more frequent the check in, the more potential for locating; but that also means using more battery. Track Mode and SOS are emergency locate functions allowing for 5 minutes of locates outside the normal cycle. The more frequently these are enacted, the quicker the battery will drain. 

- Awake vs. Sleep:  Sleep Mode is how the device saves the most battery as it is a fully dormant state. If the device is always on the move, its only chance for a battery break is the rest period. But even then, it is still checking in every 2 minutes to the server for diagnostics/ see if Track Mode has been pressed. So, if the device is being used in a way where it will rarely go into sleep mode, you will see shorter battery life than if it experienced periods of sleep mode throughout the day.

- Environment: This is the most overlooked factor. Like all GPS trackers, ours is designed for outside use. This is because GPS signals come down from satellites. As those signals rain down, they bounce off every surface. So, open areas provide the most accurate locates and best battery consumption. When in and around buildings, these materials interfere with the signals. If too much interference is experienced, the device will switch to WiFi Touch or Cell ID to locate. But, every time it starts a locate cycle, the device always tries GPS first. So, if indoors or in and around large/ thick structures, this can impact locates and battery. To combat this, there is WiFi Touch when indoors. But it takes multiple WiFi Touch signals to generate a single locate; it only takes one GPS signal to generate a single locate. Because of this, being used indoors will see expedited battery drainage (sleep mode will help combat this). 

Partnered with environment is cell service. The PF+ communicates on the 3G GSM network. This is how it sends data to the servers. When the servers update, you see this reflected on your app/ online interface. If the device is being used where cell service is limited or non-existent, the device will whirl in the background trying to connect until it does connect or the battery dies.
