Why won't my iPhone 16 Pro Max screen turn off when idle?

I'm with the same problem(iphone 16 pro) even with the always on display when a notification appears while locked the screen keeps awake until i manually lock the phone, i've checked and the raise to wake is also turned of.

• Tap Settings
• Tap Display & Brightness
• Scroll down to Always On Display
• Turn it off

I was in this position too. Noticed yesterday that my phone was quite warm after being supposedly asleep in my bag. Didn’t think anymore about it till this morning when I noticed the screen wasn’t sleeping as it should after 30 seconds.

After reading this discussion I went to check my settings, but rebooted first.

I remembered changing my display zoom settings to larger text the previous day, so I switched back to default. Unfortunately now I’m not sure if the reboot or reverting this setting fixed it 🤦🏻 Turning larger text back on didn’t cause the same issue to reoccur though 🤔

Because you have the Always On feature enabled in Settings/Display & Brightness.

Nope like I said earlier that’s the FIRST thing I checked. What else could it be ? Because it’s NOT that

You said "Nope it’s set to default 30 seconds"

There is no time setting at all for Always On Display, it is ON or OFF, which is why I assumed you checked “Auto Lock” which DOES have a 30 second setting, and did not check Always On Display.

Yes this is driving me nuts, display just wakes up and refuses to go off till phone is manually locked.

Always-on display is off. Raise to wake is off too. Auto-lock is 30sec

Thank you. That fixed it. 😊

it was the always on feature. I disabled it.

facing this exact issue. i have always on display off and set auto lock to 30 seconds. but when a notification comes, the display doesn’t turn off.
