What I’m implying is whether or not the AW4 (or any AW really), could get this feature via some hack.Not sure what you are asking. Yes the software tells the display hardware to be dimmed, the screen refresh rate to be lower, the CPU/GPU chipset to go into its new low power mode, the watch faces to go into their dark versions, complications to be disabled (or into their own low-power modes), etc. The software is what controls when it all happens (based on the hardware that tells it the watch orientation and a timer) and it controls what happens.
This isn't the type of thing that would be done automatically in firmware or anything, it's definitely part of Watch OS 6.
Yeah I realize that. Given how similar the two series are, I was just wondering how someone with an S4 might get that feature.I mean, I’m sure it’s possible. Whether such a hack is feasible is another matter altogether, though. The very nature of the Watch makes this…really difficult.
My understanding is that the Series 5 has hardware which allows it to reduce the display’s refresh rate down to 1 Hz when not actively in use. Not qualified to comment on whether that’s in the display or the S5 chip, but it seems like either or both have been updated to be more energy-efficient and allow this feature to work without slaughtering the battery.Yeah I realize that. Given how similar the two series are, I was just wondering how someone with an S4 might get that feature.
Nope. Apparently the S5 has a whole new hardware display driver that allows it to refresh the screen as little as once a second.Yeah I realize that. Given how similar the two series are, I was just wondering how someone with an S4 might get that feature.
Another view of what this question may be asking; will there be a toggle for 'Always-on'?
I believe that there would be -- especially if you have to put the watch in power reserve.
Enabling the Theatre Mode also disables the always-on display.There is indeed a toggle for 'Always On', in Settings->Display and Brightness (that's also where you can tell it to hide "sensitive complications" in dim mode, so others can't see your health readouts).
