Tip to sync Charge 2 with iPhone

[Blitzenk9]

For those of you who have Charge 2 with iPhone. My Charge 2 was CONSTANTLY unsyncing. After weeks of struggling, I figured out that by just turning my phone off and then back on it synced back up again. Works every time now. I was going days without using my Fitbit 😔. It’s worth it to me to be able to use it. Just thought I’d pass this song for those of you who are still struggling with this

Hey there @Blitzenk9, it's nice to see you around the forums! Sorry to hear you've been having constantly syncing issues between your Charge 2 and your iPhone. Thanks a lot for sharing the tip that has worked for you, I'm pretty sure this will be of help for other users. 

I'd like to add to anyone who come across with a syncing issue to verify each requirement before moving on to the troubleshooting steps.

• The Fitbit app is installed on a supported iPhone or iPad. To check, see http://www.fitbit.com/devices.
• The latest version of the Fitbit app is installed on your phone or tablet. 
• Your iPhone or iPad has a cellular data or Wi-Fi connection.
• The software on your iPhone or iPad is up to date. To check, tap Settings > General > Software Update.
• The Bluetooth setting on your iPhone or iPad is on. To check, tap Settings > Bluetooth.
• Your iPhone or iPad isn't managing other Bluetooth connections. For more information, see Is the Fitbit app for iOS interfering with other Bluetooth devices?
• If you use more than one device to sync, make sure the other device isn't nearby. If the device is nearby, turn off Bluetooth on it. For more information, see Why won't my Fitbit device sync to another phone or computer?​
• Your Fitbit device's battery isn't critically low.
• The firmware on your Fitbit device is up to date as described in How do I update my Fitbit device?

If your device still won't sync, try these steps:

1. Force quit the Fitbit app. 
2. Go to Settings > Bluetooth and turn Bluetooth off and back on.
3. Open the Fitbit app.
4. If your Fitbit device didn't sync, restart your iPhone or iPad. 
5. Open the Fitbit app.
6. If your Fitbit device didn't sync, restart it. For more information, see How do I restart my Fitbit device?
7. If your Fitbit device won't sync after the restart, log in to your Fitbit account on a different phone, tablet, or computer and try to sync.
8. If your Fitbit device still doesn’t sync, remove all other Fitbit devices from your account and from the list of connected Bluetooth devices on your iPhone or iPad and try to sync.

Hope this also helps, I'll be around. Keep me posted anytime!
