Since updating to Connect 2.0 my watch no longer goes into auto sleep mode. I find that whenever the watch is remotely close to my iPhone, it connects to the phone & then stays on, effectively draining the battery. The only way to put it to sleep is to press the clock button, and even I have my suspicions if that is effectively putting it to sleep.
My watch used to be able to go nearly a week without a charge & that included going on 4-5 runs with it. Now, it barely lasts 2-3 days unless I consciously put it to sleep.
What is causing this? I am not actively engaging with the Garmin app, nor is the watch sending or receiving any data to/from the app. The watch used to go to sleep like clockwork after sitting idle. Now, it never does.
