Feniks 3 firmware rollback

Good morning

My old Feniks 3 has just been replenished with new battery after the first did not last longer than a day or two. Unfortunately, the new battery exibits the exact behaviour. I have uninstalled everything that could cause drain, switched off wifi and bluetooth connections, and deactivated my Strava account. Still the same.

Today I tried rolling back the firmware to pre-V9 but cannot get it to work. Each time it restarts, the version is upgraded to 9.6.

Any suggestions?

Nothing to add other than the fact that my Fenix 3 running FW 9.6 still gets at least a couple of weeks with no activities on the original battery.

My Fenix 3 is also still going strong on FW 9.6, I don't think going back to an older FW will fix this.

If a hard reset didn't work, maybe the new battery was not really new (happened to me a few times). Did the battery arrive more than half full or totally flat? If it was flat, try another one from a different source.

Otherwise, give it a week or two with normal use and charge cycles. There is power management logic in the watch that should adapt to the characteristics of the new battery.

Possibly the battery gauge just needs to be calibrated. Do a soft-reset, and then fully charge the watch (keep it on the charger ~1hr more, after the indicator shows 100%), then use the watch till it shuts down. Repeat the cycle twice.

Thanks trux, very useful indeed. And thanks for the link to the guide. In all my searching I never came across this page.
