What is a Fitbit?

Calling Fitbit a step tracker would be a gross understatement—it is a widely popular fitness product that allows you to track all your fitness activities over the course of your day. It also has features normally associated with smartwatch and smartphone devices.

Different Fitbits offer different features for users; one can track things such as sleep, heart rate, menstrual cycles, steps walked, etc. The company has created multiple variants of this health tracker to ensure there is a Fitbit for everyone.

Among the many variants that are popular among many global users are:

  • Fitbit Luxe
  • Fitbit Ionic
  • Fitbit Charge 3
  • Fitbit Charge 4
  • Fitbit Versa
  • Fitbit Versa 2
  • Fitbit Versa 3
  • Fitbit Inspire 2

Fitbit Premium membership allows you to purchase features like SPO2 measurement, heart rate variability, breathing rate fluctuations, and skin temperature, something that other devices in the domain do not offer.

Your Fitbit experience will depend a lot on your own device, its features, and your budget, as well as your dedication to achieving your health goals. Here is more details about Fitbit in case you were interested

What is Fitbit Charge 4

Launched in March 2020, the Fitbit Charge 4 comes packed with features that include “Active Zone” minutes that alert you when you are close to fulfilling your customized work-out target, focusing on the following, among others.

  • Cardio
  • Heart rate and its fluctuations
  • Calorie burning

These minutes give you a measure of the amount of effort you’re putting into your workout sessions and track your progress too.

It also comes with smartwatch features such as call alerts, notifications, and replying to texts (for Android users only). It just needs a Bluetooth connection to your mobile device.

It has a long battery life that can power your Fitbit Charge 4 for 7 days; if you use its built-in GPS tracker, the battery lasts 5 hours. It is waterproof up to 50 meters.

The trendy fitness tracker comes in Black, Rosewood, and Storm Blue colors.

Setting up your Fitbit

Step 1

Charge your Fitbit till fully charged. This is highly recommended for first-time users.

Step 2

Download the Fitbit app from the Play Store app on your Android device. Once downloaded, install the app.

Step 3

Switch on your Fitbit. To do this, long press the button on the side of your Fitbit device.

Step 4

Set up your Fitbit account on the app. To access your profile, click on the profile picture. You can set up your device using the option, “Set up a device.” Once complete, this will connect the app to the device.

Step 5

How to Sync your Fitbit with your Android device

Syncing your Fitbit to your mobile device is the fastest and easiest way of connecting your Fitbit device to the app—this loads your daily work-out/health details to the app on its own without any action required on your part.

However, as I go on to discuss later, if you have trouble syncing your device/app, it is one of the most common issues faced by all Fitbit users. Read on to know more about solving it.

Your Fitbit device can store 7 days worth of your information. Health tracking is important to keep track of your progress, so to avoid any loss of data, it is important to back up your updates to the Fitbit app.

After your initial setup, the tracker routinely syncs with your Android smartphone and updates your data in the background itself. This allows you to fit it and forget it.

There are 5 simple steps to manually sync your Fitbit device to the app.

1. Switch your Fitbit device on.

2. Switch on your Bluetooth, in your Android phone. You will find the Fitbit device and other devices in the list. Select and connect with your Fitbit device. 

3. Open the Fitbit app on your Android phone, and open your Fitbit account.

4. Select the tiny Fitbit icon on the app’s homepage, which should either be at the upper or lower corner of your screen depending on the Android smartphone you use.

5. A pop-up menu will appear with the time, with your time of last synchronization (last sync time). On the same pop-up, you will find a sync icon. Selecting that will synchronize the data from your Fitbit device with the Fitbit app.

Fitbit Losing Bluetooth connection: How to Fix it

The most common issue faced by Fitbit Charge 4 users

The Fitbit Charge 4 is one of the most popular Fitbit devices in the market. However, many users have complained about facing a common issue: the device keeps losing the Bluetooth pairing, and often smartphones cannot successfully pair with the device. 

Now, there can be a few reasons for it.  

In an Android device, once the Fitbit tracker gets paired, it is automatically listed as a trusted device. Therefore, it does not show up as ‘connected’ in the traditional way. So, there is no way for the user to check if the device is connected to their phone or not.

For use, the app and the device need to connect as well. On your Android device, you will be requested to accept the connection between the tracker and your phone. Follow the following steps to pair your device with Android.

How to Add Fitbit tracker as a Trusted Device

The Fitbit tracker can’t pair with Android phones using Bluetooth but instead is automatically added as a trusted device. Every time a user logs out of the app and logs in again, the app prompts the user to accept the connection all over again. 

In case of a sync issue, try to remove the Fitbit device from your list of other devices and re-adding it. Some features and processes on the Fitbit differ from standard Bluetooth devices as it uses Bluetooth 4.0.

Sync regularly and be on top of your goals!

How to Fix Lost Bluetooth Pairing Issue

This issue, while common, can be solved. My research has given me insights into fixing this problem, and all you have to do is follow these steps carefully.

  1. Go to Bluetooth settings on your phone and select/long-press Charge 4. A popup menu for forgetting this device will be displayed. Select it.
  2. Turn off your other Bluetooth devices that may be nearby. This will ensure there is no interference over the process.
  3. Restart both your phone and tracker.
  4. Once restart is complete, switch on your Bluetooth and open your Bluetooth device list.
  5. An option to pair your device should appear. Tap on the pair option to connect your Bluetooth. Resynchronize your Fitbit app to sync your data.
