Earlier this month, Fitbit updated the Sense and Versa 3, its two most recent smartwatches. While this update brought several new features to both smartwatches, the Fitbit Sense has been suffering from a battery drain issue for a few months. According to Gadgets & Wearables, the issue has been present since late March 2021.
Fitbit has acknowledged the issue, which does not stem from the smartwatch itself. A Fitbit Community moderator explains:
Our team is aware of the Sense not holding charge when syncing with iOS devices and they're working to bring a fix as soon as possible. In the meantime, we recommend force quitting the Fitbit app on your iOS devices to prevent the battery from draining when syncing.
Switching off Bluetooth on your iPhone will improve the Fitbit Sense's battery life, but that is true of any Bluetooth-enabled smartwatch. Currently, the Fitbit Community post has amassed over 350 replies, which you can read here. However, Fitbit has not stated when it plans to release a fix. The company published version 3.43.1 of the Fitbit iOS app yesterday though, which supposedly includes 'bug fixes and performance improvements'. It remains to be seen if this update addresses the battery drain issue, mind you.
