Battery Scenario 2

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 Life Scenario 2 is below. In my sons backpack during school. Battery lasted 1.5 days.

Day 1

Device has been powered overnight, was unplugged from power at around 7:45am and put in my sons backpack.

Michael had late start school today so I can see in history as he traveled to school and looks to be a minute or so late to school… hmmm.


At 9:48am I look at the PocketFinder app and see that his device had been locating every 10 minutes right when I took it off of power for about 30 minutes, went into sleep mode, then woke up and started tracking just after 9am through now. Because he takes his backpack with him from class to class, the PocketFinder+ isn’t going into power conservation sleep mode, it’s staying active. Power level is now 90%.


At 9:52 am device is updating its location regularly. Battery now at 88%.


At 1:16pm I update the icons with pictures from my phone and add names.


This is the “List” view.


At 1:17pm battery level is now 66%. Michael’s device was locating pretty regularly through the school day except for 1 hour when he had his backpack in his locker during lunch.


This is what the history looks like of the stacked up locates while he’s moving around at school from class to class.


The device tracked home and then was mostly in sleep mode with just a few more locates when his bag was moved (hopefully getting homework done!) while at home. Its last locate before going into sleep mode is at 6:21pm with 46% battery.


Day 2

The next morning he went to school at 8am and then to a Dr. Appointment. At 10:23am battery level was at 41%.


By 4:34pm battery level was at 16% and this was the last locate. In situations where your children are taking the device with them to school and they are keeping it with them to where it’s not going to be in sleep mode much you’ll want to plan on charging it like you would your cell phone. Even though a full subsequent charge only takes 2 hours, most customers’ will power it overnight.

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.
