Background Syncing

[dRuEFFECT]

Can someone please explain if "All Day Syncing" is supposed to persist over several days and/or device rebooting? I has been my experience that the Fitbit devices and the iOS app will not continuously sync week over week without manual interaction with the app. It has been a tremendous disappointment that after all these years, the app will not sync with the device unless I actually open the Fitbit app.

Please do not respond suggesting that I make sure I enable "All Day Syncing" or reinstall the app or relink the device. This has been a persistant experience across 4 generations of Fitbit products and 4 generations of iPhones.

From Fitbit's product perspective can someone please confirm what is the expected syncing behavior if I do not open the Fitbit app for a week? If it's expected that device data will eventually sync on its own, then I can tell you it does not and there's a bug that needs fixing.

I really need this fixed. I'm willing to provide any support or logs to document the issue and ensure this gets into the bug fix backlog.

Bumping this thread.  Been researching this issue for months and your post is the best question on this persistent issue.  Yes, is this SUPPOSED to only sync “all-day” if you open the app every other day or what?  My all day sync just fades out and stops working unless I manually open the app—which I don’t always do.  I seem to get a few days at most.

hoping someone from Fitbit actually explains how it’s SUPPOSED to work.

For what it's worth, I haven't had this problem since I switched to Android. Android has more accessible system settings that you can disable the OS from killing background processes.  ¯\_(ツ)_/¯
