Hi everyone,
Since the global blue triangle screen issue on January 28th, my Forerunner 965 has been experiencing excessive battery drain. Over the past week, it got worse: the heart rate sensor stops working intermittently, and the battery now drains completely in less than 8 hours—even with no activity.
Details:
-
Previously normal battery life (~5 days) dropped significantly post-incident.
-
HR sensor fails during workouts (no data gaps before).
-
Latest software/firmware updates installed (version X.X.X).
-
Factory reset performed—no improvement.
Has anyone else faced this? Any fixes or advice before contacting Garmin support?
Thanks!
