How can I schedule power on and off on my iPhone 16?

There is no current feature on iPhone to schedule an iPhone to power on or off.

If this is a feature you'd like to see (I certainly wouldn't want such a feature), you can share your thoughts with Apple here --> Feedback - iPhone - Apple

I didn't go there, because even with an automation to power the phone off, it requires a confirmation step. Not quite what the Author is looking for if they really want to have the phone power off at a specific time and power on at a specific time on a schedule.

And the link with the discussion suggests this is a feature which had never existed. The second link takes you to user guides. So again, it's a feature which has NEVER existed on iPhone. And it doesn't today, so arguing about this will get you nothing.

If you sent feedback that’s all you can do. There is NO option in iOS to do what you want. There are NO alternatives either. An iPhone cannot be set to power down or power up on a time schedule, period.

Rather than turning the iPhone off, consider suppressing notifications and other activity through the Focus feature. The Focus mode can be automatic based on time or based on location.

Rather than turning it off to save battery, put it on the charger instead.

Force-quit buggy apps, or better yet uninstall them.

This is the RIGHT advice. Powering off the phone won't preserve the battery in any meaningful way. I NEVER power my phone off. My phone is iPhone 16 Pro Max, which I've owned since launch day and my battery health is 99%. My phone is plugged in to charge when I go to bed at night EVERY night with a sleep focus enable on a schedule. I wake to a phone charged to 100%, good for a full days use.

I believe that Mac OS X / macOS may once have supported scheduled power-up and power-down times on some Macs. (I think that I may once have seen controls for that on an old iMac.)

But that was a different operating system running on a different hardware platform.

If it is truly off, how can any software turn it on? If you turn your car off, can it turn itself on?

And if it can turn itself on, it couldn’t possibly be completely off.

Well......there you go, just being logical and stuff. Logic is so often not seen on this forum.

The closest you'll get is iOS's Inactivity Reboot feature where if your iPhone is inactive for 3 days, it will automatically reboot and bring it back to the Before First Unlock State.

Again, something I didn't address (but I am aware of) as it doesn't come close to what the Author is looking for and of course what they are looking for doesn't exist.

FWIW, unless Find My Network is turned off, it uses battery and isn't really off.

And some folk report here that their phones spontaneously turn on.

Seems that I’m almost a year-late in discovering this feature … and it’s a “biggie” for me.

I'm curious. Why is this important to you? Why would I want or need to do this? No snark, just curiosity.

Well … fair question … maybe not THAT important … 🫣

I have a few devices which are infrequently used (all usually kept running in Airplane Mode).

One device (for now, more next month) is an iOS 18 iPhone. [It’s actually the “hot spare” for my primary “carried” device]

I generally get to all of them within 72 hours … but not always.

I had noticed the iOS 18 iPhone asking me for the passcode unexpectedly. (I think to myself … “Hmmm, has it really been a week already … ??? … it’s asking so I guess so.”

It hadn’t happened enough for me to detect the trend … but I’m sure it would have “triggered” me soon enough; esp. once there are multiple iOS 18 “spares.”

Hello~ I will reiterate what our other knowledgeable members have stated… there is absolutely no way currently to do what you are asking for in iOS. What else can be said?
