Hello,
I have recently changed my old iPhone X to a new iPhone 15 Pro and noticed something that I consider abnormal.
About 10% of my daily battery usage is caused by Garmin Connect app running in the background.
During nighttime hours when the phone is iddling, Garmin Connect is causing 100% of its battery usage.
I have never experienced that on iPhone X - battery usage by Garmin Connect was negligible.
I have only one device - Garmin Instinct 2 connected.
iPhone 15 Pro is brand new and on the latest iOS update.
Any clues?
For now, the only solution is disabling background app refresh and manually killing Garmin Connect after each use.
But that changes the thing to be completely manual and I have to wait some time (a minute or two) after starting app until it synchronizes with the watch.
