It took me a long while to figure out why my 735XT (and previous 235) battery would sometimes drain unusually quickly, when the watch wasn’t being used to track exercise(GPS). I finally noticed that it was rapidly connecting and disconnecting to Garmin Connect...even though the app was closed. The only way to stop it, was opening the app and then closing it again
iPhone 6-Plus. This has happened intermittently on last 3 major iOS versions. Just installed iOS 12 today, still happening. In fact, with iOS 12 opening and closing the app does not stop the connect/disconnect
