Garmin Watch Frequently Disconnects From Your Smartphone

Fitness fanatics and outdoor adventurers find Garmin smartwatches to be a great choice because of their reputation for accuracy and GPS functionality. 

However, some owners have experienced a bothersome problem with their Garmin watch frequently disconnecting from their smartphone. 

The synchronization of data, notifications, and other smart features may be affected by this disconnect. 

Here are some common causes of this issue:

  • The connection between your Garmin watch and smartphone may be interfered with by nearby Bluetooth devices. 
  • On your Garmin watch or smartphone, outdated firmware or software can cause connectivity issues. 
  • Disconnections might be due to low batteries in your smartphone or Garmin watch. 
  • Your smartphone’s network signal quality can affect the Bluetooth connection if it is poor or unreliable. Data synchronisation might be interfered with by poor cellular or Wi-Fi connectivity.
  • Your Garmin watch’s Bluetooth range with your smartphone is constrained.

Let’s now look at some troubleshooting techniques to fix the Garmin watch regularly disconnecting from your smartphone issue:

Make sure the most recent software and firmware upgrades are installed on your smartphone and Garmin watch.

To update your Garmin watch’s firmware, follow these steps:

  1. The first step is to connect your watch to Wi-Fi or Garmin Connect Mobile.
  2. Launch your smartphone’s Garmin Connect app.
  3. Choose your watch from the list of devices.
  4. Check whether there are any updates available and apply any outstanding firmware updates.

Syncing Problems Caused by Bluetooth Issues on Your Garmin Watch

Many people have found themselves annoyed by not being able to sync their workouts and other information onto the Garmin Connect app because of an unstable Bluetooth question.

You must sync your watch with the Garmin Connect App on your phone if your steps or the activity you recorded on your device do not appear in the Garmin Connect app or your Garmin Connect account. 

A green dot from the My Day view of the Garmin Connect App should appear on your Garmin device to show that it is connected to your phone or another mobile device.

However, if that doesn’t work, your Garmin won’t connect, claims it’s not connected, or the app says it couldn’t connect, we have useful tips to fix this.

Before we get started with the troubleshooting, it is important to double-check the following:

  • Ensure that both your phone and your Garmin are not in airplane mode. Turn off airplane mode if it’s active.
  • If your Garmin is connected to two or more mobile devices (such as a phone and a tablet), make sure they are not close to one another, turn one of them off, or disable Bluetooth on one of them.
  • Remove additional Bluetooth-enabled gadgets from your phone for the time being. Try turning off any other Bluetooth-enabled devices, such as speakers, headphones, etc.
  • Confirm that power saving mode is not active on your Garmin.
    • On your Garmin device, go to Menu > Power Manager > Battery Saver > Off or Menu > Activity Settings > Power Save Timeout and select Extended rather than Normal to access these settings. 
  •  Check to see if Garmin Connect is updating or running in the background. The Connect app must be running in the background for it to function.
    • For Apple devices, turn on Background App Refresh under Settings > General > Connect.
    • On Android, turn on Background data by going to Settings > Apps > Connect > Mobile data & Wi-Fi.

Once you’ve verified the above, you can use these steps to sync your Garmin watch and your smartphone:

  1. Open the Garmin Connect app on your phone.
  2. Select the My Day tab from the bottom menu if necessary.
  3. Look for your Garmin device’s image at the app’s top.
  4. You must first enable Bluetooth on your phone if you see a red dot. Wait for your Garmin to show up connected after opening the Bluetooth settings on your phone and turning them on.
  5. If there isn’t a dot, turn Bluetooth off in your phone’s settings, wait 20 seconds, and then turn it back on. Watch to see if your phone’s Bluetooth can connect to your Garmin.
  6. A green dot should appear next to the image of your Garmin watch or tracker.
  7. To sync data from your watch, tap the manual sync button (the circular arrow icon) in the upper-right corner of the Garmin Connect App. 
  8. If your device hasn’t been connected for a while, syncing may take a while.

Bluetooth is Causing Excessive Battery Drain

The majority of Garmin watches come standard with Bluetooth connectivity. 

It makes it possible for functions like call and message notifications, music management, and data syncing via Garmin Connect to work between your watch and smartphone.

While Bluetooth is a great way to improve your Garmin experience, if it’s not used properly or there are other issues, it can also significantly contribute to battery waste.

By its own nature, Bluetooth is made to be energy-efficient.

Most Garmin watches use the Low Energy (LE) version of Bluetooth, which has been designed to use as little power as possible. 

However, how you use the Bluetooth functionality on your watch will determine how much of an influence it has on your battery life.

Here are the main Bluetooth-related causes that can cause battery drain:

Continuous Connection: Your watch will use more energy if it keeps your smartphone connected continuously. When features like phone alerts, notifications, or continual data syncing are enabled, this occurs. 

Music Playback: Using your Garmin watch to manage Bluetooth music playback on your smartphone might significantly reduce battery life. 

Data Syncing: Data syncing between your watch and the Garmin Connect app frequently, especially if it happens automatically and without interruption, might drain your battery. 

The following tips will help you prolong the battery life of your Garmin watch without sacrificing the convenience of Bluetooth features:

Create Custom Notifications: Choose the notifications that are most important for your daily activities and workouts. The power consumption caused by Bluetooth can be considerably decreased by turning off pointless notifications.

Control local music playback: Consider downloading music straight to your watch or utilizing Bluetooth headphones directly attached to your watch for a more power-efficient experience.

Smart Data Sync: Use the Garmin Connect app to change the syncing frequency of your watch. To save energy, it can be wise to switch to manual syncing or less frequent automatic syncing.

Regular Updates: Keep the Garmin Connect app and the firmware of your watch up to date. Updates from manufacturers that increase power efficiency are frequently released.

Battery Saving option: A battery-saving option is available on several Garmin watches, which restricts functionality and increases battery life. Use this option when your battery life is at stake or when you aren’t actively tracking a workout.

Bluetooth Interference From Other Devices

Any Bluetooth-enabled device, including your Garmin watch, may have connectivity issues as a result of Bluetooth interference from other devices. 

Multiple Bluetooth-enabled devices nearby may interfere with one another, resulting in problems including poor connectivity, disconnections, and weakened signals.

Here are some useful tips you can use to lessen Bluetooth interference and enhance the functionality of your Garmin watch:

  • Search for nearby Bluetooth devices by identifying and locating them. Phones, tablets, laptops, headphones, fitness trackers, and other smartwatches fall under this category.
  • Make sure your Garmin watch is within the associated device’s recommended Bluetooth range. If you move too far from a connected device, connectivity problems may occur.
  • To lessen overall interference, disconnect or, if possible, turn off unused Bluetooth devices.
  • Since 2.4 GHz Wi-Fi and Bluetooth share the same frequency range, utilizing Wi-Fi may result in interference. If you have control over your Wi-Fi router, think about switching the channel or, if possible, switching to a 5 GHz network.
  • Remember that physical obstructions like metal items and walls can block Bluetooth transmissions. 

Pros and Cons of Using Bluetooth On Your Garmin Watch
