Garmin has issued a new beta software update for Forerunner 945 LTE smartwatch. The Latest 6.04 beta version brings plenty of new features to the smartwatch with other fixes. It is massive firmware that counts in many new functions, fixes, and improvements. The first notable feature is the Real-Time Stamina tool that helps users to measure pace during running or cycling.
Further, it added a Sleep insight feature, which tracks your sleep quality, score, and duration. Moving ahead, you will notice auto workout detection has been provided for the run/walk exercises. It could have been provided since launching, though it is most welcomed here. The Forerunner 945 LTE gets cross-country ski power zone editing support and idle time to activity summary has been added.
