Battery Scenario 3

PocketFinder+ 3G GPS, Wi-Fi, Cell ID Personal Tracker

"How long does the battery last?" is one of the most common questions that we get asked and the accurate answer is…it depends! I’ll give you 3 different scenarios below along with full information about how it works so that as a prospective buyer you can apply the information here to your specific need and form your own expectation of battery life. Our customer service team would also be happy to talk with you about your use case and provide an estimate.

The following tests were done using the default power setting of: “locates” every 10 minutes with option for Track Mode to start in less than 2 minutes and instant SOS. Images are from both our App and web login. Details on other “Power” setting options with more frequent locates or settings for longer battery life and how it all works can be found below the real test case examples.

3 Battery Life Scenarios:

  1. In my 2nd grade daughters backpack tracking her to and from school. Battery lasted 4 days.
  2. In my sons backpack during school. Battery lasted 2 days.
  3. On my key chain in my pocket with frequent movement during the day. Battery lasted 10 hours.

Battery Scenario 3 is below. On my key chain in my pocket with almost constant movement during the day. Battery lasted 10 hours. See below for different power settings to further extend battery life in this scenario. In this case, I have the setting for 3 minutes of locates every 10 minutes.

I disconnect my PocketFinder+ from power at approximately 7:45am and connect it to my key chain.

At 9:51am I take a look at my app and view history of morning locates. I can see the different 3 minute locate bursts as I left my home, went to each school and traveled to the office.




This device is in my pocket and we can see me moving around the office with new locates every 10 minutes.


At 9:57am battery level is at 76%. The blue dot is where my iPhone thinks it is inside our office.


At 1:16pm I update the images for my family’s devices and can see that they are all recently displaying new locates.


I can see that both kids are still at school.


I kept moving at the office and left at around 6pm. My battery lasted until 6:41pm which is just over 10 hours.

Important: If you choose a power setting to allow your battery to last even longer like the 20 min locate setting you can still press “Track Mode” from the app at any time between locates and it will begin to track in less than 2 minutes. J An SOS button press also automatically starts the device sending location information.

Details on how a PocketFinder+ tracks utilizing all three location technologies:

When a PocketFinder+ gathers location information it will gather 3 minutes of as many quality location points as it can. These location points are typically 10 seconds apart. We call these “locates”. Our system will filter poor locates so sometimes in history you will see many locates and other times just a few. If GPS signals are not available, like when you are indoors, your PocketFinder+ will sense Wi-Fi and Cellular ID signals to triangulate its location.

With the next app update you will see the following locate options under the “power” tab:

  1. Constant locates when not connected to power. These locates will typically be approximately 10 seconds apart. When connected to power, it will locate every 10 minutes when sensing movement.
  2. Locates every 4 minutes
  3. Locates every 10 minutes
  4. Locates every 20 minutes

*Pressing “track mode” from the app or web will start your PocketFinder locating in less than 2 minutes during the time between locates

*If the SOS button is pressed three times, the LED will turn red and it will immediately begin sending as many accurate locations as it can for the next 3 minutes

*If your PocketFinder does not sense movement for 30 minutes it will go into what’s called “sleep mode”. While in sleep mode, pressing “Track Mode” will not start the device locating. It will again automatically locate when it starts moving and wakes up.
