Power off 5s????

[Max(IT)]

That's actually debatable. All iPhones since the original have been running with under clocked components. They may run at the maximum "performance" allowed by the configuration, but it's well within the design spec.

Not to mention, if there is actual stress, it's a lot shorter than when someone streams video for a long period, or uses their phone as a hotspot. The heat output alone is a lot higher from those two actions than simply starting up or shutting down.

Following the "reboot causes stress" logic, one should never, ever update their software, as that process requires one or two reboots.

Anyway, continuing to argue this isn't really worth it. The phone will be just as happy NOT rebooting often, anyway, and I agree that's the way to go since rebooting often is just a waste of time.

I didn't say it is an unbearable stress. I just said it's another thermal stress so, since it's not necessary to do that every day, I can't see any reason to suggest it.

I recommend rebooting using the fibonacci method. Beginning when the device is new, reboot it on day 1, day 2, day 3, day 5, day 8, day 13, day 21, and so on until you replace it with a new device. This is proven to keep the iPhone chakras maximally aligned for ultimate power.
