[Wear OS Software and Hacking General] Nazo:
Perhaps I shouldn't have given a specific example since that seems to have caused confusion. It's everything that uses voice. Including, for another example, Messages. And like I said, it will show the correct text on the screen then put in the wrong thing in the actual input. I haven't had time to test how it will do now, but so far everything -- including voice -- handles a lot better with TicSystem disabled, so so far so good, but the real testing won't come for a few days at the very earliest depending on how I need it.

I have WiFi and location enabled but tilt-to-wake is off. Other than tilt-to-wake, the watchface would be the biggest battery user of anything active, but if you have any background apps that use a lot that may play a part. Of those settings tilt-to-wake is probably the biggest killer since no one holds their hands completely still. I use touch-to-wake so if I need to wake it I only have to touch the screen rather than tilt and there are a lot fewer accidental wakes (though not none since a lot of things have just the right resistance or whatever to fool a modern touchscreen if you bump or touch them. I find cables in particular are the worst.)

That won't help longevity. But it shouldn't make a lot of difference anyway. The main things that affect battery longevity are total charge cycles (which ultimately works out the same whether you charge at ~50% twice or whether it's at, say, ~10% once,) voltage (and if your charging more frequently resulted in it being at maximum voltage for longer periods of time that would be worse, but even that probably works out about the same really,) and finally temperature (if you do a reset and it starts working overtime updating all the components and apps then it gets really hot and it probably is best to have it plugged in so it's hopefully drawing most of its power from the USB source rather than the battery.) Overall longevity is the one thing there's not a lot of point in worrying about since there isn't much you can do about it one way or the other with a watch. (Now, with your phone that is a different story.)

Oh, I see. I thought you were talking about really heavy usage or something. Nevermind then I guess. I'm such a light sleeper that I could set the watch next to me if I wanted it to be my alarm, but of course my phone works so much better that I just place it next to me on a charger. (Better still, it has a LED screen like this watch, so I can run "Night Clock" or whatever configured to have a really really dim clock while on the charger that I can look at when I wake up and need to know the time.)

There isn't much else that can be done. Even if you reset and prevent the update to Wear OS for a higher overall system efficiency it's not going to get a lot better. You can turn off the ambient display if you haven't already, but the cool thing about a LED screen is only the pixels being used use power and even that is based on their actual brightness since there is no backlight, so a good ambient display doesn't use a lot. If you want any better than that you'll have to give up using a watch like this and go to something like the Pebble with an eInk or whatever they call it display, but that one lacks access to services like Google Assistant. I'm hoping Garmin or someone else will do one similar to the Pebble with modern capabilities one of these days, but don't have high hopes considering. (Fitbit bought them, but it looks like they just wanted to eliminate a prospective competitor and pretty much tossed everything they paid for into the trash bin. Garmin has some watches that are getting at least closer to what the Pebble was, but last I looked they didn't have any that actually were true smartwatches yet.)

Most can do shortcuts. Pujie Black has configurable buttons you can add to the watchface where you want including one that can show a radial menu to select multiple shortcuts from. It's not the only one that can do this by any means and the free one I had before had configurable buttons too (though no radial menu. That's kind of a cool feature IMO. That way I can have one button that does multiple things instead of a bunch of buttons all over the watchface.)

Anyway, I don't want to get too much further off-topic here. I just wanted to verify that it wasn't something going really wrong with the setup. I guess it is ultimately your usage -- particularly the fact that you wear it while sleeping.
