Instinct 3 45mm Solar Charging Issue

Sorry if I ask. How you managed to have 33 days? Do you have HR and Pulsox on or off? I only manage to have 11 days with a full charge with both on all day. It seems low to me. The epix 2 gave 21 days in the same situation.Thanks.

Yes, I have all that off as I have an AW Ultra 2 and Fenix 8 that have better sensors.

Disable PulseOx. It is the biggest battery consumer, and appart of the Altitude Acclimation feature it is not used for anything, so practically useless (unless you need to continuously monitor your SpO₂ for some reason). I get the estimation of 31d with more or less the default settings (PulseOx off, HR and BT on). The reality is worse, though, anyway, but that's another topic.

Thanks for the answer. I will.

But to me the battery of this I3 solar seems disappointing. I am trying to change from EPIX 2 pro 51 to I3 50 because i absolutely love the I3 MIP display but with my epix i do 21 days (no AOD) with the same settings of the I3 and here I do only 9 days. Maybe in summer with the sun the situation will change.

With I3 50mm I get 39d estimate at 100% charge (with more or less the default settings; again, no PulseOx!), so that's still quite a bit more that the 21d of the Epix.

Yep but the 21days on EPIX are with the POx on all day. I will try to deactivate and see in the EPIX how much it will do.

I would not rely much on the estimates. They are usually way off. Personally, I only use the battery percentage, which is the only relevant value. 

However, Epix 2 51mm has the max battery life in smartwatch mode specified as 31 days (no AOD, no PulseOx), while at I3 50mm it is 40 days, so still more. And I doubt that the PulseOx on Epix 2 consumes less power than on Instinct 3, since they both use the same sensor. 

Infact this is the point. I don't understand how it's even possible. The only reason I can think is that the SW in I3 is really not optimized for battery usage. The next thought is: the SW would be in big part similar to I2X or not? Why all this bugs and inefficiencies?

When I tell 21 days on EPIX they are real days. I tracked each charge (a bit empirical but you can see where i reached almost 0 battery and 19 days passed).

I assure that I do exactly the same lifestyle with the I3 and exactly the same option enabled. The only differences is that epix has the AOD off but still i play a lot with it.

I will say that the battery on the I3 is worse (with the exact same settings) than a model from a few years ago:

Does disabling PulseOx have any effect on other values? Like the sleep score? Or is it a single score and you can just enable it once a month to check if everything is okay and disable it again?
