Rather than all-or-nothing (full features or Power Reserve) I think there's a decent middle ground.

By disabling Hey Siri and Heartrate Monitoring today I ended the day with 61% battery left which is double my usual level.

I prefer pressing the Digital Crown to using Hey Siri and Heart Rate monitoring is most useful when I am doing cardio and I didn't do the gym today.

So I disabled them and I am amazed how huge their impact is.

So I suggest if you're burning through the battery one day and/or have forgotten your charger disable these two and you can probably squeeze 2 days out of your Watch with minimal adverse impact (especially compared to Power Reserve mode).
 
I mean i guess if you're trying to make it last more than one day that could be useful. But on a normal day, you could have Hey Siri and heart rate monitoring ON and end the with about 30%.
 
So you could have Hey Siri and heart rate monitoring ON and end the with about 30% which is still several hours of battery, or disable two of the main features of the watch and end the day with about 60%. Why would I want to do this? What is the obsession with ending the day with as much battery available as possible?

In case you ever *are* in a situation where your battery is low -

All night party?
Working extra shift?
Business trip and forgot your charger?
Red eye flight?

Use your imagination.
 
I think that HRM is also used to calculate things like calories burned when not actively exercising, so that could also be affected.

I'm also curious what effect turning off the wrist-raise function would have on battery life. It's mostly academic at this point, though, since I don't have any problem getting through the day.
