1. Garmin smartwatches often require pairing with the Garmin Connect app for full functionality, but connection issues with iOS devices have been reported.
2. Many users experience persistent sync problems, especially after iOS 26 updates, with some unable to connect at all for weeks.
3. Alternative synchronization via wired connection is available for workout data, but it does not support notifications, making the device less useful.
4. The impact of these issues varies based on the specific model and usage, with some features becoming nearly unusable.
5. It remains uncertain if iOS 26.5 will resolve these connectivity problems for all users.
Garmin Smartwatch and iPhone Connection Troubles
Depending on the exact model, Garmin smartwatches can be used without a phone but mostly need to be connected through a smartphone app or Garmin Connect to work that’s fully. The connection between iOS devices and Garmin watches, however, has been problematic for many users. Reports from users indicate significant sync issues especially after updating to iOS 26, effecting many features. It’s hard to tell how many are affected, but it’s not just a small number of weird isolated problems, this is a broader issue.
Persistent Connection Problems
Some users say the connection problems have been ongoing for weeks now, to a point where their iPhones cant connect with Garmin watches at all. For instance, a Reddit user shared they haven’t been able to connect their Garmin Forerunner 255 Music with their iPhone 16 running iOS 26.4 since February. Several others have confirmed they face the same problem. Re-pairing devices and deleting Garmin apps didn’t seem to fix the problem at all. The issue is quite frustrating for those impacted.
Limited Functionality and Potential Fixes
On Garmin’s support forums, someone with a Garmin Fenix 8, an iPhone 15 Pro, and iOS 26.3 also reported connection troubles. Depending on what model you own and how you use it, this can make the smartwatch pretty useless. Interestingly, syncing workout data over a wired connection still works without Wi-Fi, so at least that part functions. But, of course, notifications won’t arrive that way. It’s uncertain if updating to iOS 26.5 will fix the issues for all users though, yet there are some alternatives for notifications directly on the watch which might help.
