v9.36 Official Software Fast Battery Drain

Thank you very much!!

And now I should reach out the support here in France?
Because of an update ?

Yes, you need to contact the support, and get a replacement watch, so that the engineers can diagnose your watch and find out why the suggested solutions, working well for others, did not work for you. They may perhaps do the diagnostics remotely, without sending in the watch, but you have to contact them anyway.

I would prefer an official answer from Chris or the Garmin crew to my question

That's why the best thing is contacting the Product Support, exactly as Chris advised you already. 

BTW, Garmin also offers sending you a replacement watch in advance. They just ask a caution deposit for the time being until receiving your watch.

Personally, in addition to the suggestions from Chris, I'd recommend also just letting the watch completely discharge untill it shuts down, and then fully recharge (or even letting it on the charger longer). Although it is not the best practice doing it all the time, when you do it occasionally, you won't kill the battery. One of the often discussed possibilities of the issues with battery after a firmware update, is the case when the battery calibration data gets reset during the update. The watch then needs to see the full charging cycle to recalibrate the battery gauge. It is quite well possible that there is in fact no unusual drain at all, just the battery level indicator does not work accurately.

It is done. ;-)

Nope. Not now anyway. I have provided screen capture of two different widgets that this does seem like a calibration (knowing the minima and maxima) issue but a consumption issue by hour. But... You are perhaps on a good lead. Of well... I'll wait for Garmin France answer.
But thank you for the idea.

but a consumption issue by hour

If the battery calibration data is lost or wrong, and needs to be reacquired, then the consumption by hour will be wrong, of course, too. You can only find the true battery stamina if you overcharge the watch for a few hours, and then let it discharge until it shuts down. Any battery indicators, regardless whether the built-in gauge, or 3rd party apps, are just estimates based on the calibrated min, max, and the current voltage of the battery. And besides that, the battery voltage is influenced by the temperature, so the gauge will always be just a raw estimate (unless you permanently keep the watch at the same temperature).

This is super-confusing.

If the drain issue comes up and persists that means my hardware is broken? So it does not make sense to wait for the next software update, because the issue will come anyways with the next update?

If you really tried all the suggested solutions, then nobody can answer that without a detailed diagnosis of your watch, and searching why it behaves differently than at the most other owners. That's why the last suggestion is contacting the Product Support, who is the only one who can do the diagnosis directly on your watch.

However, guessing from another post of yours in another thread, it looks like you did not upgrade the firmware yet, hence I do not quite understand where your concerns about faulty hardware come from. The issue was fixed practically for everyone with one of the suggested fixes (disabling Strava and long Garmin segments, reboot, soft reset, hard reset to factory defaults, full charge-discharge cycle,...)
