Some Forerunner 945 users may experience battery drain issues after firmware updates. This is a common issue. To resolve battery drain issues on a Forerunner 945, you may use the following two-step process below:

  • Perform a soft reset of Forerunner 945 – Reboot your Forerunner 945 running watch to perform a soft reset of the watch. A soft reset is sufficient to resolve the battery drain issues on a Forerunner 945 device post a firmware update.
  • Hard reset of factory reset – if a soft reset fails to resolve the battery drain issue, you may perform a hard reset or factory reset of the Forerunner 945 smartwatch. Factory reset will cause data loss. Therefore, we suggest backing up user data and smartwatch settings through the Garmin Connect app. After the factory reset, you can restore data and settings by syncing the device with the Garmin Connect app.

Firmware update on Forerunner 945 is an automatic process. You cannot roll back the firmware update or go to a previous version of firmware on the Forerunner 945 on your own.

For this, you require a manual process of reverting the firmware files to an earlier option. Sadly, the nature of automatic updates prevents the firmware from being rolled back automatically.

Manual download of firmware files for Forerunner 945 is no longer available through the Garmin website for the stable release firmware versions.

However, if you participate in the beta program of firmware updates, you can download the beta version of firmware updates for the Forerunner 945.

We strongly discourage manual upgrades of firmware for any Garmin smartwatch, including the Forerunner 945.

Forerunner 945 is currently on firmware version 13. The firmware update process is completely automated and the software update is sent to your device by Garmin automatically.

The last firmware update for Garmin Forerunner 945 happened in July 2023.
