How can I adjust settings for auto sleep mode on my iphone11?

Hello deggie,

Thanks for clarifying! This can be done by going to: Settings > Display & Brightness > Auto-Lock > Then, you can select the time you'd like.

This link will provide you more info on changing Auto-Lock Settings: Adjust the brightness on your iPhone, iPad, or iPod touch - Apple Support

Cheers!

Hello riverboat-dave,

Thank you for using Apple Support Communities! I understand that you need help with adjusting your settings. I am happy to help the best I can.

Set Do Not Disturb for bedtime on iPhone

• To silence iPhone when you’re going to sleep, you can turn on Do Not Disturb. This setting dims your display, silences calls, and sends notifications to Notification Center until you unlock your iPhone in the morning.

Turn on Do Not Disturb for bedtime

• Go to Settings > Do Not Disturb.
• Turn on Do Not Disturb, then turn on Scheduled.
• Tap From, then set the beginning and ending times for your sleep. During these hours, a moon logo will appear in the status bar.
• Turn on Dim Lock Screen.
• To silence incoming calls, tap Allow Calls From, then select No One.

Do Not Disturb turns off automatically at the end of the quiet hours you specify. To turn it off sooner, tap the Do Not Disturb notification on the Lock screen, then tap Turn Off. When Do Not Disturb is off, notifications resume.

To set a regular bedtime schedule, see Set an alarm or bedtime schedule on iPhone - Apple Support.

Cheers!

Change the settings on Auto Lock.
