Standby Mode not staying on iPhone 15 Pro

I have a 15pro with the most up to date version of IOS. I want to use the standby mode as a clock at night


No matter what I do with settings the screen goes off after approximately 30 seconds and I have to tap or move my hand to get it back on.


I have tried forcing restart, resetting the phone, checking the settings but I can’t understand why.


It seems to be an intermittent issue for many users?


I’m also using an apple mag safe charger and genuine apple mag safe case

I was having the same problem intermittently and found that when the phone was in low power mode (which it often is at night) the screen shut off after about 20 second even though it was set to never. Turning off low power mode resolved the issue. This is still a bug in my book as the phone has to be charging to go on standby.

i to have this problem! Mine goes one issue further! In the middle of the night it stops being in standby all together, meaning if I tap the screen to get it to come back up it’s the normal login screen! This only happens later in the night though, if I tap the screen earlier in the night it will show the standby clock and calendar in Red….


Although, again, some time durning the night it’s as if it looses connection with the stand and reconnects on its own, although it doesn’t go back to the standby mode! Kinda sad!

Just done hard reset, see how it goes. I also think, when 15pro is charging standby clock stays on, once fully charged then display goes off….also on the big digital clock which shows time, date, temp and any alarm set (very cool) the temp is stuck on Fahrenheit and I’ve tried everything to get it to change to Celsius but no luck 🤦🏻‍♂️

My 15 ProMax will show the correct clock/time in red for about 10sec and then defaults to a clock that never moves showing 10:10/30 sec. The screen doesn’t respond to movement🤷🏻‍♂️🤦🏻‍♂️


I’ve tried a soft and hard reset, tried deleting the clock widget and adding it back in, etc…all with negative results.

I've done all the above

Followed Apple recommendations precisely

And STANDBY still works perfectly, a delightful red image

Until suddenly it disappears...😱


I've been trying for a while and still haven't found a fix!

The best phone on the market and they can't fix this irritating issue...!!!

And now I'm on 17.3.1 and it's still no better...

C'mon Apple, make this work please. The third party nightstand alarm clocks work perfectly well, Standby is a better solution but please resolve this irritating issue.

Security issues seem to be the issue. I can get parts working since Lock Screen widgets allowed but only weather is available nothing but clock and weather we should be able to allow on a separate screen when standby is allowed after messing around with it not all options normally there can be allowed like reminders is a scroll option but can’t allow
