Hello Fc0171,
Thank you for reaching out to Apple Support Communities, and we'll be happy to help in any way we can. We understand you're having issues with your screen locking to fast. You can adjust the time it takes to lock as described here to resolve the issue: Keep the iPhone display on longer - Apple Support
"Change when iPhone automatically locks
You can set how long it takes iPhone to automatically lock.
Go to Settings
> Display & Brightness > Auto-Lock, then choose a length of time.
Keep your Lock Screen visible
On iPhone 14 Pro and iPhone 14 Pro Max, the Always On setting allows a dimmed version of your Lock Screen to stay visible, even when your iPhone is locked, so you can glance at your Lock Screen to check essential information, like alerts, the date, time, and information in your widgets.
The display automatically turns off when iPhone is face down or obstructed from view, not near a paired Apple Watch, when a CarPlay session begins, while Continuity Camera is in use, while Low Power Mode is on, while Sleep Focus is on, or at your usual bedtime.
Always On is on by default. To turn it off, go to Settings > Display & Brightness, then turn off Always On."
We hope this helps.
Cheers!
