I have been using Forerunner 935 with the latest version of Garmin connect and there was never an issue with the battery consumption (I have a brand new Samsung S24 Ultra). The battery lasted whole day of video watching and still 20% left. Now I got a new Epix Gen2 Sapphire Pro and on the first day at 6PM the battery on the phone was dead. Garmin connect consumed 25% of the battery. What is going on? Just by switching the watch what might have changed?
