Sometimes delay when turning off screen ios 16.1

Thanks for the reply, AppleUserFFFFFFD.

We'd like to have you use the steps below to adjust how your iPhone responds to touch, then test to see if that helps:

1. Go to Settings  > Accessibility > Touch > Touch Accommodations, then turn on Touch Accommodations.

2. You can configure iPhone to do any of the following:

• Respond to touches of a certain duration: Turn on Hold Duration, then tap  or  to adjust the duration. (The default is 0.10 seconds.)

• Prevent unintended swipe gestures: To increase the amount of movement required before a swipe gesture begins, tap Swipe Gestures, turn on Swipe Gestures, then adjust required movement.

• Treat multiple touches as a single touch: Turn on Ignore Repeat, then tap  or to adjust the amount of time allowed between multiple touches.

• Respond to the first or last place you touch: Choose Use Initial Touch Location or Use Final Touch Location.

If you choose Use Initial Touch Location, iPhone uses the location of your first tap—when you tap an app on the Home Screen, for example. If you choose Use Final Touch Location, iPhone registers the tap where you lift your finger. iPhone responds to a tap when you lift your finger within a certain period of time. Tap or  to adjust the timing. Your device can respond to other gestures, such as a drag gesture, if you wait longer than the gesture delay.

On a supported iPhone model, you can prevent touches on the display from waking iPhone. Go to Settings  > Accessibility > Touch, then turn off Tap to Wake.

If this persists, Contact Apple Support for next steps.

All the best.

Greetings AppleUserFFFFFFD, 

We’re understanding you to say that when waking your iPhone, there is a delay in the display waking up. We’d like to have you test a few things - 

1. Waking your iPhone with the side button

2. Waking your iPhone by tapping the display

3. Waking your iPhone by raising the device. 

Then note whether the delay happens in all circumstances. 

If you haven’t already, we also want to make sure you have restarted your iPhone since the update was installed. Restart your iPhone

Thanks.
