Anyone experiencing high battery drain should start with a hard reset (holding the power button for up to 15 seconds). If this does not resolve the issue, more information will likely be needed from you…

hello Former Member,

what i can tell for sure is that currently (with only spo2 activated during night and daily steps tracking) the battery life of the 945 is way worse compared to the 935. with 1-2 workouts…

Can't we have statement from Garmin if they have noted that there is an issue with battery drain and they plan to solve it?

I think my problems start with the upgrade to 2.80 Firmware.

Does someone have 2.70 firmware for downgrade and test this old version.

downgrade is not so easy, because there was a sensor update too and downgrading sensor updates i am not sure if possible, it could be, that the problem comes from the sensor update and not from FW 2.80

I just bought a 945. It's currently running FW 2.80, and I'm having similar battery drain issues to everyone on this post. Interestingly, though, I notice that the excess battery drain only occurs when I connect my watch to my phone. Before connecting to my phone, the battery is on track to last around 2 weeks, as promised. The worst part, though, is if I first connect my watch to my phone and then disconnect it, the battery drain still persists. Anyway, I thought I'd add my input as another data point.

unfortunaly downgrade to FW 2.70 didn't solved the problem

In my opinion 2.60 was the last good FW where the battery consumption was still not increased.
