7X Solar battery life is ridiculous

With a number of issues I've had with the Fenix 7 lately, I thought I'd post something a bit more positive today.

My experience with the battery life on this watch has been absolutely insane. Absurd, even. I last charged it 6 days ago, last Tuesday morning. Right off the bat, I used quite bit of battery while I was going through all the settings, configuring my activities, etc, which took several hours and drained the battery down to 95% by that evening. But it's now Monday morning the following week, 6 days later, I've used around 2 hours of multiband GNSS and used the flashlight countless times, and my battery is at 82% (showing 23 days remaining) - more than my 6X had on a full charge!

I cannot imagine any scenario where I could ever possibly have to worry about the battery dying. And for that reason, I know I definitely picked the right watch for me. Looking forward to a summer of adventure with this watch! Hopefully the firmware stability issues get worked out before then ;)

    That’s really nice! Did your watch receive some sunlight in this time? Smartphone notifications? Right now I am at 75% after four days in which I had three hours of multi band GNSS, one hour indoor cardio, many buzzes because of notifications and lots of tinkering around and using flashlight. Almost no sunlight. So a little less efficient than yours. Hopefully it’ll improve over the next few weeks!

    Good questions! It didn't receive much solar - the widget says I averaged 21k lux hours per day. Some days I had as much as 50k lux hours, but others I only had like 10k.

    Yes, smartphone notifications are turned on (vibrate only), and I probably get about 20 notifications a day.

    Your battery life sounds about right - it sounds like you used a bit more GPS than I did, and probably got less sunlight to offset it.

    Thanks for the info! Yeah my battery seems alright now that I think about it. I played with the maps a lot and I use touch a lot as well, which somehow activates the backlight, even though it is turned off in the settings. And I average at 40-60 notifications a day, so a bit more buzzing. Anyway, coming from an Apple Watch 7 (sold it after three months… I missed Garmin), this is one heck of an improvement in almost every way.

    Finding exactly the same regards the battery. Absolutely crazy.

    There we have him again. How many watches you have changed al the way? And how is it going with your real long hikes?

    Hello, is your heart rate sensor activated continuously?

    And the oxygen measurement too?

    Thanks for your feedback.

    My heart rate sensor is on constantly.

    Oxygen sensor is only on when I trigger it manually, which is a few times a week at most.

    My first week was adjustment , ended up with 8 days after setting up. I was on battery downloading Spotify etc. around 9 hours of running for 91 kms , with stryd foot pod and vibrating power setting. Gps is all system , smart recording. I use the red led blink when i run pass sundown.  I have battery saver on when I sleep with spo2 and ohr working. Spo2 only at night , notifications are beep only with calls vibration. 

    Now on week 2 and at 6 days in im at 61%. Less fiddling haha and also I turned of vibrate with my stryd app (not sure if it’s a big impact but it’s less stress for me )  Looking at 12 to 13 days before recharging with my use.  I don’t get much Solar, only once per week at around 76 to 100k.
