Forerunner 945 - Battery Life while running a GPX file

Former Member over 4 years ago

Hi there,

I would like to know how long the maximum battery life will be when in full GPS mode while running a GPX file on the FR 945?

in other words: Full GPS mode they say is 36 hours but how is that reduced while running a GPX file?

Thank you. I would keep Heart rate on, but don't need wifi or bluetooth or ox meter.

Thank you, this is most helpful. so it would be around 30hours. Is Ultratrac fairly accurate?
