Fix an Apple iPhone XR Won’t Pair or Charge 2 Won’t Sync with Fitbit

So you’ve just procured a new Fitbit and you want to pair it with your iPhone XR but for some reasons, it won’t pair or charge 2 won’t sync with your Fitbit device. If that’s the main reason why you’re here, then I encourage you to read on and try the possible solutions outlined below.

To get started in using a Fitbit device with your iPhone, you need to create a Fitbit account and then set it up. Among other requisites are a Fitbit app to be installed on your iOS device and a stable Bluetooth connection. Considering that you’ve already set up your Fitbit account and a Fitbit app is already installed on your iPhone, you’re all set to pair your Fitbit to your iPhone.

Once your iPhone is paired with your Fitbit, you’re ready to go. But if what you get is a syncing error, then you’ve got a problem to fix. Highlighted below are suggested workarounds you can try to troubleshoot software problems on your iPhone XR that might have halted it from syncing with your Fitbit device. Read on for more detailed solutions.

First solution: Force close Fitbit app on your iPhone then restart it.

Random errors on the Fitbit app usually emerged among the common culprits. Fortunately, such errors can easily be dealt with by restarting the application. Thus, this should be considered among the first potential solutions to try on. Follow these steps to force close and restart Fitbit app on your iPhone XR:

Swipe up from the bottom of the Home screen and then pause slightly in the middle of the screen.
Swipe right or left to navigate through app previews/cards.
Swipe up on the Fitbit app card/preview to quit or close the application.

After ending the application, perform a soft reset or restart your iPhone XR to eliminate minor software issues that might have triggered the Fitbit app to glitch. Here’s how:

Press and hold the Side/Power button and either Volume buttons simultaneously for a few seconds.
Release the buttons when the Slide to Power Off command appears and then drag the power off slider to the right.
After 30 seconds, press and hold the Power/Side button again until the phone reboots.

Wait until the phone boots up completely and then retry syncing it with your Fitbit tracker.

Second solution: Restart your Fitbit device.

Like any other smart devices, random errors transpiring on Fitbit devices can also be rectified by a simple restart. The method to initiate a restart on Fitbit devices may vary on each model. But the good thing about restarting your Fitbit is that it won’t delete any of your tracked activity except for calls, texts, or calendar notifications that are stored on your tracker.

If you need help restarting your Fitbit device, you can visit the Fitbit support page then refer to the outlined steps on how to restart it.

Third solution: Toggle Bluetooth off and back on.

A stable Bluetooth connection is among the key requisites for your iPhone XR and Fitbit device to sync and work as intended. Minor problems affecting the phone’s Bluetooth functions are therefore among the underlying causes. In this case, toggling your phone’s Bluetooth function will likely solve the problem. So here’s what you can try doing next:

Go to your iPhone Settings-> Bluetooth menu, then toggle the switch to turn Bluetooth OFF.
While Bluetooth is turned off, restart/soft reset your iPhone.
Then head back to Settings-> Bluetooth menu and toggle the switch to turn Bluetooth ON again.
Wait for all available Bluetooth devices to populate.
Select your Fitbit device then tap the option to pair or connect.

If that still failed to fix the problem, then you should move on and try the next applicable solutions.

Fourth solution: Forget all Bluetooth devices from your iPhone.

On your iPhone XR’s Bluetooth directory and remove any other Bluetooth devices. Keeping other Bluetooth devices may still cause conflict or halt your iPhone from syncing with your Fitbit device. To forget or delete Bluetooth connections from your iPhone XR, simply refer to these steps:

From the Home screen, tap on Settings.
Select Bluetooth. Make sure Bluetooth is turned ON.
Navigate to the list of Bluetooth devices then tap on the information “i” icon next to the name of the Bluetooth device you want to forget.
Then select the option to Forget this device and confirm action when asked.
You can also delete or forget your Fitbit device so you can set it up again as new. This will help if your current Bluetooth connection is corrupted.

Reboot your iPhone after forgetting all Bluetooth devices. After it reboots, head back to the Bluetooth menu from Settings, enable Bluetooth to view all available Bluetooth devices in range. Select your Fitbit device then retry pairing or connecting it with your iPhone XR.

Fifth solution: Uninstall then reinstall Fitbit app on your iPhone.

This can be the key to fixing the problem if corrupted Fitbit app is to blame. The app might have been totally borked and so it’s no longer able to work. As resolution, uninstall the broken app from your iPhone XR and then reinstall the latest version of the app from the App Store. Here’s how:

Tap Settings from the Home screen.
Scroll down the left menu then select General.
Tap iPhone Storage.
Select the Fitbit app.
Tap Delete App.
If prompted, tap Delete App to confirm.

A faster way to delete apps from your iPhone XR is through these steps:

Lightly touch and hold the Fitbit app icon until it jiggles.
Then tap on the X at the upper-left corner of the Gmail app preview.
Tap Delete when prompted to confirm action.

After deleting the Fitbit app, restart your iPhone XR then reinstall Fitbit app with these steps:

Tap to open the App Store from your Home screen.
From the App Store start page, tap the search icon (magnifying glass) at the bottom right.
Enter Fitbit and then tap the search button.
Select the desired Fitbit app from the search result then follow the onscreen instructions to download and install the app on your iPhone.

Give your iPhone another restart after installing the application. Also restart your Fitbit device before trying to pair and sync again.

If you have several Fitbit devices on your account, remove all other Fitbit devices from the list of connected Bluetooth devices on your iPhone XR and then try to sync with the desired Fitbit device again.

Other options to fix charge 2 won’t sync issue on iPhone

Update Fitbit app and iOS. Verify and ensure that you are using the latest version of Fitbit app on your phone. If you haven’t configured your apps to auto-update, then there may be some critical pending updates that you need to manually implement. To check, navigate to the App Store-> Updates menu. Then tap the Update button next to Fitbit. If multiple app updates are available, you can update all apps simultaneously by tapping on the Update All button. The software of your iPhone must also be up to date. To check for new updates on your iPhone XR, go to Settings-> General-> Software Update menu. Then follow these onscreen instructions to download and install new update available.
Reset network settings. Network-related errors on the phone are also among the factors that can cause syncing errors and other Bluetooth issues. If none of the prior methods is able to fix the error, then software resets can be deemed among the next options. Since the problem involves Bluetooth syncing, network reset is an applicable solution. To reset network settings on an iPhone XR, go to Settings-> General-> Reset menu, then select the option to Reset network settings. Doing so will erase all your current network settings including Wi-Fi and Bluetooth connections, APNs, server information and other relevant data. After the reset, your iPhone should reboot automatically and then loads the default network configuration. This denotes the need for you to re-enable Wi-Fi and Bluetooth in order to use them again. After enabling Bluetooth, retry pairing your iPhone XR with your Fitbit device and then see if it’s already able to sync.

If all else fails, then you can escalate the problem to Apple Support or the manufacturer of your Fitbit device for further assistance. There may be some advanced settings on your Fitbit device that need to be configured or your Fitbit device may need a full reset.
