Any idea on the reason for this battery drain ? Or how to fix it ?

Some tips are for example here:

• Troubleshooting guide for high battery drain
• Why is My Fēnix Watch Battery Draining Quickly? | Garmin Customer Support
• Features that Affect Battery Life on Outdoor Wearable | Garmin Customer Support

Hi, I did a soft restart (turn off the watch for a few min) then turn it back on, and it seems to have solved the problem. Strange.. I hope it will remains like this.

I have nearly all turned off and my battery drain is about 9% a day with no activities...

Did you soft-reset the watch and went through the full charging cycle (twice if necessary) as advised in the Sync / Connection Troubleshooting Guide ?

I did a soft reset couple of times and charged it to 100% and left it for an hour or two pluged to a charger. As for now, the drain is still about 8% daily.

8% a day may be quite fair, depending on the features you use.

I forgot to mention that I have a Fenix 7 PRO SS. My former Fenix 7 Solar had about 4% daily usage in the same configuration.

So if it shows 8% per day, it does not seem like you already went through the full charge-discharge cycle twice as advised in the guide, since it would take almost a month. Or did you really do the soft-reset a month ago, and already completed both charging cycles?

I have it for three days now, so I just charged it to 100% and did some soft resets. During the first two days my battery went from 45% to 20 which made me feel uneasy. I will follow your advice and let you know in a couple of weeks if it worked. :) Thx for your effort!

After the cycle nothing changed, battery usage is at about 7% daily. Maybe you have some other advice? Thank you for your help.
