Understanding Common Fitbit Alta Sync Issues

Before diving into solutions, it’s important to recognize the typical symptoms of Fitbit Alta connection problems:

  • Device won’t pair with the Fitbit app
  • Continuous “syncing & refreshing” message with no progress
  • Manual syncing required instead of automatic syncing
  • Device appears in the app but won’t complete connection
  • Pairing code appears but connection fails to complete

These issues can occur on both Android and iOS devices, with some users reporting more problems after switching between operating systems.

8 Proven Solutions for Fitbit Alta Connection Problems

1. Reset Your Bluetooth Connection

One of the most effective solutions is resetting your phone’s Bluetooth connection:

  1.  1  Turn off Bluetooth on your phone
  2.  2  Wait at least 15 seconds
  3.  3  Turn Bluetooth back on

This simple step often resolves temporary connection issues by reestablishing the Bluetooth link between your devices.

2. Restart Your Fitbit Alta

There are two methods to restart your Fitbit Alta or Alta HR:

Method 1: With Original Charging Cable

  1.  1  Connect your Alta to the charging cable
  2.  2  Press the button on the charging cable three times within 8 seconds
  3.  3  Wait for the Fitbit logo to appear, indicating a successful restart

Method 2: Without Button/Non-OEM Cable

  1.  1  Connect your Alta to the charging cable
  2.  2  Unplug and plug it back in three times in quick succession (within 8 seconds)
  3.  3  Wait for the Fitbit logo to appear

3. Force Close and Reopen the Fitbit App

Sometimes the app itself needs to be refreshed:

  1.  1  Double-tap your phone’s home button (or use the appropriate gesture for your device)
  2.  2  Swipe up to close the Fitbit app
  3.  3  Reopen the app and try syncing again

4. Check for Interference from Other Devices

Your Fitbit can only sync with one device at a time:

  • Ensure your Alta isn’t paired with other devices nearby
  • Uninstall the Fitbit app from other devices signed into the same account
  • Turn off Bluetooth on other nearby devices that might be interfering

User Tip: One user discovered their Kindle Fire’s Bluetooth was interfering with their iPhone’s ability to connect to their Fitbit. After turning off Bluetooth on the Kindle, the connection issues were resolved!

5. Update Software and Apps

Outdated software can cause connection issues:

  • Check for pending updates on your phone
  • Update the Fitbit app to the latest version
  • Ensure your Fitbit device firmware is up to date

6. Set Up as a New Device

Resetting the connection completely often works when other methods fail:

  1.  1  In the Fitbit app, tap your profile picture
  2.  2  Select your Alta device
  3.  3  Scroll down and tap “Remove This Device”
  4.  4  Follow the prompts to set up your Alta as a new device

Don’t Worry! This won’t delete your data from your Fitbit account. Any previously synced information will remain safe in your account.

7. Check App Permissions

On Android devices, ensure the Fitbit app has all necessary permissions:

  1.  1  Go to Settings > Apps > Fitbit
  2.  2  Tap Permissions
  3.  3  Enable all required permissions, especially Bluetooth and Location
  4.  4  For Android users, make sure the app has unrestricted background access

8. Let the Battery Run Down Completely

A unique solution reported by some users:

  1.  1  Allow your Fitbit Alta’s battery to drain completely
  2.  2  Once fully discharged, charge it back up
  3.  3  Try connecting again

Success Story: One user reported this method worked after trying all other troubleshooting steps without success!

Real User Experiences with Fitbit Alta Connection Issues

iPhone vs. Android Experiences

Users report varying experiences across operating systems:

“It was fine when I had Android. Switched to iPhone 15 a month ago. The issue is with iPhone.”

“It improved somewhat after I switched to iOS. It happened regularly on Android.”

iPhone 12 Pro Compatibility Issue

A notable case study:

“My Fitbit Alta worked perfectly with my iPhone 11 but couldn’t be found when trying to add it as a new device on iPhone 12 Pro.”

This suggests potential compatibility issues with newer iPhone models that might require additional troubleshooting.

Hardware vs. Software Factors

Hardware Factors

  • Bluetooth signal strength differences between phone models
  • Physical condition of the charging port
  • Battery health and performance

“I have an Inspire 2 that was flaky with syncing on one phone, but when I started using it on another phone it works perfectly. I suspect that the Bluetooth on the new phone is stronger.”

Software Factors

  • App updates sometimes improve or worsen syncing
  • Operating system differences between Android and iOS
  • Background app restrictions on newer OS versions

“After the update the sync is really good it used to be an issue before.”

Frequently Asked Questions

Why won’t my Fitbit Alta sync automatically?

Your Alta may not sync automatically due to disabled all-day sync settings, Bluetooth connectivity issues, or interference from other devices. Enable all-day sync in the Fitbit app settings, ensure Bluetooth is on, and check that your Alta isn’t trying to connect to another device nearby.

How do I know if my Fitbit Alta needs to be reset?

Consider resetting your Alta if it won’t sync despite multiple attempts, shows incorrect data, is unresponsive to button presses, or won’t track activities properly. A reset often resolves these issues without losing your data.

Will I lose my data if I reset my Fitbit Alta?

No, resetting your Fitbit Alta or setting it up as a new device won’t delete data already synced to your Fitbit account. However, any unsynced data on the device itself may be lost during the reset process.

Can using a non-original charging cable affect syncing?

While non-original cables can charge your device, they may lack the button needed for the standard reset method. However, you can still reset your Alta with a non-OEM cable by unplugging and plugging it in three times in quick succession.

Why does my Fitbit Alta sync with one phone but not another?

This could be due to differences in Bluetooth signal strength, operating system compatibility, or app permissions between phones. Some users report better success with iOS than Android, while others experience the opposite.

Can a low battery cause syncing problems with Fitbit Alta?

Yes, when your Alta’s battery is very low, it may have difficulty maintaining a stable Bluetooth connection. Charge your device and try syncing again. Interestingly, some users report that completely draining the battery and then recharging can resolve persistent syncing issues.

Connection issues with your Fitbit Alta or Alta HR can be frustrating, but most sync problems can be resolved with the troubleshooting steps outlined in this guide.
