vivoactive 4/4s (now running sw 6.90) powers off randomly, including when interacting with Wi-Fi

I got the latest software update: version 7.20. Result:

- If I try to connect to a wi-fi network the watch shuts down with 100% (no power supplier plugged)

- [APPARENTLY] after an activity (cardio) when Save is tapped it saves and doesn't shuts down. I'm saying apparently because this was a cardio activity 10 secs long. Tomorrow I'll test it with something longer and I'll report back.

For me it's not a big trouble the need of being plugged to the power supplier when connecting to the wi-fi. The problem with this is that it tries to connect to sync with the music provider and then the watch shuts down. This happens mostly during the night so you lose the sleep tracking.

I'll report back the results of tomorrows activity.

More info after a real activity.

I did a Cardio (light walking) activity involving GPS. Finished it with aprox 70% of battery. After saving the activity in the watch, it powers off.

I tried to set the watch a Bike riding activity, involving GPS. Battery was aprox 60%, the watch powers off, when I tap the "Bike" option in the activities selector.

Also, during the night, the watch also powered off with the battery above 65%.

So, not a big improvement with this new version. Very sad.

Please feel free to email me and I would gladly give any information you may need.

In addition to this I noticed that when ever the watch is not connected to my phone, it shuts down when saving an activity.

Same here,

It started after last software update,

Definitely it is related to Wi-Fi.

Hope Garmin will release a bug's update for that...
