My Vivoactive 4 is not 2 years old (purchased 23/10/20) and after removing any non garmin apps & multiple resets, I have just about had enough!
It worked great for about 10- 12 months then just started randomly shutting down every couple of days. Did some research and advised that non Garmin apps can cause an issue, so I deleted anything that wasn't Garmin, maybe 2 items it total. No changes.
I tried charging more regularly even when watch says battery 60%, I tried to see what I was using to cause it to shut down, no pattern just random shut down.
Today I cannot keep on, I start it up & with in 20 seconds shut down even when battery is 48%.
I paid $AU600 to purchase and expect far more from my Vivoactive4 than what I have received
