Fenix 8 51mm SOLAR Battery Drain

I’ve had to raise a support ticket in the end. My Fenix 8 51mm Solar is performing significantly worse than my old Fenix 7 47mm Solar.

100% charge on Friday

6 Hours of GPS activity over the weekend in sunny weather and 150-200k LUX each day. Finished Sunday night at 65%. Woke up this morning to 50% (15% drain over night!).

It’s typically draining 8-10% a day when there is no activity as well.

Steps I’ve tried (not that any are acceptable, as they differ from my 7).

1. Latest BETA software

2. WiFi Off

3. PulseOX off.

4. Backlight is at lowest setting.

5. Gesture Backlight off.

    Yup same here, F8 51 Solar is draining more than my AMOLED without ANY use!

    my Tactix Delta Solar lasts 30 days WITH activities... Something is really wrong here and especially since they said they fixed it and now its broken even more..

    Well I guess I'll wait for some sort of statement and most importantly a fix from the Garmin team and if it doesn't improve quickly then I'll return my F8 51mm Solar. I am really disappointed and I am a long time user of both the Fenix and Enduro series. I would probably switch to another brand.

    I bought the 51mm SOLAR to see if it would stack up well against my AMOLED - battery life wise. It's worse. Hopefully they will fix this but this is simply unacceptable especially when all the product specs + marketing advertises something else.

    I think it's the perfect time for Garmin to say something, anything OFFICIALLY! To be honest I'm really p....d and regretting my decision to give them a credit. Firmware in current state is pure rubbish, missing a lot of good functions from F7, unstable and with huge battery drain. I was shocked when I checked battery consumption a while ago - 1.59%/h when totally idling, without any activity at all, watching movie. In simple calculations - 1,59%/h gives 38%/d and a little above 2 days of usage... AW Ultra performs better! Garmin dev team - it's time to do and say something or you will loose more and more customers! It's over 1k USD watch, not a toy Rage

    Same issue here. 47mm fenix 8 solar, battery only lasts a few days and I'm not even doing anything with it. Extremely disappointed and will return it

    Does anybody tried turning off incident detection for all activities? This should helped with 18.14FW for F7 and this bug seems similar.

    Problem continue after 11.89 for me. 13% of battery lost  in 12 hours after an activity.

    WiFi on

    PulseOX off.

    AOD off

    no use during night.

    F8 51 Solar and I am loosing about 10% of battery every 24 hours with about 1 hour of gym activity a day.

    I also created a support ticket for my F851 Sapphire Solar.
