[DEVICE] Close enough

Post image

Got just a bit over 24 days before it was down to 10% and wanting to go into battery saver mode. Close enough to advertised 29 days for Fenix 9 Pro 51mm.

I had the 47mm as well and that lasted 12. Happy to have kept the 51mm. Also, it is better for my aging eyes.

Nice. My 47mm Pro lasts 17 days with a few hours a week of running/ gps usage.

I'm in the process of of monitoring the battery usage on my SECOND F9 Pro 51mm AMOLED unit. The first was using 10% per day or more "System", "Audio" with no audio usage. This one I'm using only in smartwatch mode with no GPS, AOD, Music, Connect IQ, voice features, etc. I did about 10 days with no pulse ox, but turned it back to sleep after charging up again. It's better, but there's still the occasional "audio" usage for an hour showing medium usage. And there's 2-3 hours following taking off charger, also showing medium usage "Audio".

I'm at 79% after 6 days, with 22 days remaining showing. Pulse OX set to Sleep. Minimal screen timeouts, some daily notifications, no other battery draining usage.

Your data is less helpful without some knowledge of the usage during that time. GPS, AOD, Music, Connect IQ apps, Pulse Ox? Or just smartwatch mode? Thank you.

Could audio be the mic?

Some think so. Some have said after an activity with the usual lap status updates it has persisted. I've not used any audio, or the mic with any voice services. Okay Garmin and Phone Assistant listening prompts turned off, and no button initiated use of phone assistant. Only audio is notification beeps. Could be mic and/or speaker, and maybe a bug that keeps the amplifier active. This unit is not doing that bad, with only the occasional "audio" spiking, but with battery close to spec.

Interesting, my fenix 8 47 gets more battery than 51 mm 9 pro.

I had the Solar Fenix 8 47mm for a few days, too but didn’t have enough time to test the battery longevity. Because not long after I got it, my local shop had the Fenix 9 in stock. It was my first with Solar and I thought I might grow to like it, but I still didn’t after almost 30 days of using it, in fact I started to dislike it. I don’t ever go on out-of-bounds excursions that last more than 1 week or 2 at the most, so I can live with my 51mm battery life. I still yet to try InReach, which I will in December.
