Garmin Fenix 6 users report severe battery drain after software updates

Users of the Garmin Fenix 6 series are reporting significant battery life degradation following recent software updates. According to reports on official Garmin forums, some owners have seen their device autonomy drop from approximately 13 or 14 days to less than 40 hours per charge.

Specific complaints involve the Fenix 6 Pro and Fenix 6X Pro models. One user noted a battery consumption rate of 2% to 3% per hour after installing version 26.00, while another reported that a Fenix 6 Pro Solar went from 10-12 days of battery life to nearly a single day, with discharge rates reaching 5% per hour even without GPS or music active. Further issues have been linked to subsequent update version 28.2.
