Good point. But that also means waiting much longer while it starts up before you can use it. I’ll see if turning off Bluetooth makes it last any longer. I also put it in Airplane mode, and low power mode.
Aside: I’m not sure how to even turn it off! When I press and hold the power button (which USED to give me a power off option), the border of the display window glows, which is probably some Siry/AI thing. I’m sure there’s a setting to turn that off, and also to power off without doing that…ok, there’s a power off option in Settings / General. Is there still a physical way to power down?
