The Garmin vivosmart 5 fitness tracker has been confirmed as officially supporting Body Battery TrueUp. This latest version of the feature was announced at the start of this year for wearables like the Fenix 7, Fenix 8, Forerunner 255, Venu 3 and vivoactive 5.
Now, a Garmin support page for the Body Battery feature lists the vivosmart 5 as a compatible wearable for Body Battery TrueUp. This appears to be a relatively recent development, though the exact date of the update is unclear. Body Battery TrueUp has not been mentioned in any releases for the fitness tracker; the change log for the last update, version 3.29, simply stated that there were stability improvements. However, one Reddit user suggests that the Body Battery TrueUp feature is already working on the vivosmart 5 (curr. $149.99 at Amazon).
As a reminder, the Body Battery feature helps users of the vivosmart 5 to monitor their energy levels throughout the day. The score, a number from 5 to 100, is calculated using data like heart rate variability (HRV), stress and activity. The latest version, Body Battery TrueUp, syncs your Body Battery data across multiple Garmin devices. It is also calculated using data collected by your various Garmin wearables, which should make the metric more accurate.
