Battery drain after firmware update

There is a chance that your Epix Pro (Gen 2) smartwatch battery may drain faster after updating the firmware on the smartwatch. This seems to be a known issue.

It can easily resolved by performing a soft reset. To resolve battery drain issues on the Epix Pro (Gen 2), you may follow the process below:

Perform a soft-reset of the Epix Pro (Gen 2) smartwatch. In other words, reboot or restart the Epix Pro (Gen 2) smartwatch. Most battery drain issues arising out of firmware updates of the Epix Pro (Gen 2) get resolved with a soft reset of the smartwatch.

If the soft reset of the smartwatch does not resolve the battery drain issue on the Epix Pro (Gen 2), you will need to perform a hard reset or factory reset. Before proceeding with a hard or factory reset, you must back up the smartwatch settings and user data. All user data and settings are lost after a factory reset. We suggest backing up the watch data using the Garmin Connect app to prevent data loss. Once the hard reset is complete, you can sync your smartwatch with the Garmin Connect app to restore data from the backup.

If the hard reset also fails to resolve the battery drain issue, we suggest contacting Garmin customer support for further help.

The manual download of firmware 15.77 for Epix Pro (Gen 2) is not possible. The update can be installed using the Garmin Express or the Garmin Connect applications only.
