iPhone connection to the computer LOST when the iPhone auto-locks during Back-up

Is there a way to keep the iPhone connected to the computer when it auto-locks during Back-up?

Main Issues:

iPhone Backup to Computer stops when iPhone Screen Auto-Locks

iPhone disconnects from computer when it auto-locks

I am trying to do a full encrypted backup.

I CANNOT do an encrypted backup if Screen Auto-Lock is turned off.

(Why? If auto-lock is off, protected data is deleted for security)

I am Using Apple Devices App....... NOT iTunes.

Computer: Windows 11

iPhone: 12 Mini, iOS 27.0.1

Connecting iPhone and Computer with USB-C to Lightning cable

I am presuming all Apple Experts will give me this quote from the HAL 9000,

“I'm sorry, Dave. I'm afraid I can't do that.”

I want to go do something else while it's backing up!!!!!

Dang it, Apple!!!!

The iPhone stays connected during a local encrypted backup while you walk away by adjusting your display sleep settings and Windows USB power options.

How to Keep the iPhone Awake and Connected

Change Auto-Lock Temporarily (or Keep the Screen On):

- Go to your iPhone Settings > Display & Brightness > Auto-Lock.
- If you are worried about the data protection claim, note that you can run a backup while Auto-Lock is active as long as the phone remains unlocked and plugged in during the start of the transfer, or you can temporarily set Auto-Lock to a longer time (like 5 or 10 minutes) to let the initial handshake complete.
- Alternative: If you need the screen to stay on without locking yourself out of security requirements, simply tap the screen or let an app that prevents sleep run while plugged in, or use a physical/software method to prevent the PC from going to sleep.

Disable Windows USB Selective Suspend

- Windows 11 often cuts power or puts USB ports to sleep when it thinks a device is idle or the screen changes state.
- Open Device Manager on your Windows 11 PC.
- Expand Universal Serial Bus controllers.
- Right-click your USB Root Hub / Controller properties, go to the Power Management tab, and uncheck "Allow the computer to turn off this device to save power".
