Fenix 6 sleep tracking starts just before or just after 4am each nigh/morning & GPS update issue

I know sleep tracking isn't supposed to be mega accurate but this week I have had sleep ofless than 4 hours for the past 3 days yet the body battery is over 95% which indicates a sound nights sleep.

No tracking has occurred prior to just before or just after 4pm. Prior to this all was well though this isn't the first time I've seen the same problem. Last time I just happened to wake around 2.30am and I saw the watch display lighting up then turning off in a regular loop. There was an issue with a GPS update failing and the watch was restarting. I reinstalled the software which didn't help but then I turned off auto update and wifi connectivity and the problem wen away.

Now its back again even with wifi and auto update still off. Anyone else having issues with thes or the 'stuck' GPS update issue which after 'install' still shows as being there to update again?

I have slep for 6 to 8+ course, but less than 4 hours logged! Sorry if that wasn't clear.

I have the same issue. Every night between 3am and 4 am, there is no record of HR and sleep. Furthermore, the fenix 6 consume between 15 and 20% of battery. I already call Garmin, they told me to do a hard reset. It worked but each time a connect the watch to garmin express for firmware update, the issue happens again. Their solution is to send the watch back ... but with maybe 1 month for the replacement :-(

Coming to the F6 Pro via the Fenix 5 Plus I find sleep tracking on the F6 Pro far more accurate, the F5+ would often report I was getting 12 to 13 hours sleep, often thinking I went to bed hours before I actually did, and not really tracking waking period.

The F6 Pro is far better at sleep tracking.

I've not had any update loops, but my policy is never to connect to Garmin Express and turning off auto-update is one of the first settings I change when I get new watch.

Try setting altimeter auto calibration not during activity to off., it worked for me. You will find this in the sensor parameter of the altimeter
