I have a feeling these things are heavily related to both WiFi (congestion/protocol/support for sleep & awake/distance to AP) and cellular (if enabled), in addition to other usage (like Bluetooth, including distance to host phone). This is also (educated) speculation.

Also device age. My Series 3 originally lasted about a day and a half but is under a full day now with a couple years of cycles on the battery.

  Well of course battery age, but the GPs were talking about the latest watch, so I assumed it was more about battery life from the start. From what I understand, impact of radio on battery life is very real but often invisible / not thought about. Cellular really can chew through battery when the base stations are far away.

    IMO battery age is still part of the discussion when talking about the shiny new model. If I buy a Series 7, two years from now it's going to be two years old. That seems obvious but people seem to gloss right over it. When the AirPods first came out there were a lot of reviews saying "Battery life is about 5 hours, this is just barely acceptable but it's not a problem." And then two years later the same authors were writing articles complaining that their AirPod battery life has gotten unacceptably short as if they'd never owned anything with a non-removable battery before and had no idea it was going to happen.

    This. The battery life on my phone, which I typically just leave laying around my desk, just about doubled after I switched providers. I used to have almost no signal with the previous provider, going up to 2-3 bars with the new one. I'm sure the modem was pushing maximum tx power trying to stay associated (and it would typically alternate between minimum signal and no coverage states). Maybe I should have bought a signal booster for my office instead. I got one for my car because I would consistently drop calls in one spot; with the booster I had 5 bars the whole commute. Before COVID, anyway.
