Edge 840 now takes very long to sync

One of the reasons I upgraded to an 840 was reviews about the sync time being much faster than my previous device. For a long time, this has been the case. The device has synced activities within a minute of me ending the activity. 

Over the past couple of updates, something has changed. My activity now doesn't sync, takes forever to sync or requires I do a dance of turning BLE/syn off and back on on my phone and Garmin Edge. 

Are there any steps I can take to make this better, like it was when I purchased my device? 

  • How are you syncing. My 840 syncs one of three ways: to iPhone thru bluetooth; or via WiFi; or thru a cable to a Mac. Usually it is to the iPhone using bluetooth. Once in a while that iPhone bluetooth sync doesn't happen immediately and I just open Garmin Connect on the iPhone and click the little circle in the upper right next to the word "Home" and it sync immediately. I suspect this has to do with the iPhone bluetooth connection as it almost always happens before I can even take my iPhone out of the seat bag on the bike. The other two ways also work quickly. If your sync works quickly thru a cable to a computer, that would point to a bluetooth RF connection vagary, and bluetooth does have once in a while interruptions as anyone using bluetooth headphones can tell you.
