I have an iPhone 15 Plus running iOS 26.6. When I charge it sideways in StandBy mode, the display eventually turns black. Is there a setting to change how long the StandBy screen stays visible? Also, can StandBy be used while the phone is charging in a vertical or otherwise non-horizontal position?

Go to Settings > StandBy > Display. Depending on the options shown on your phone, you can set the display to turn off automatically, stay on for a while, or remain on continuously. StandBy still requires the iPhone to be locked, connected to power, and positioned sideways on a stable surface.
StandBy is intentionally limited to a sideways charging setup. Plugging the phone in while it is upright, or simply holding it sideways without a suitable stand, will not activate the full StandBy interface. For upright charging, you would need to use the regular Lock Screen and its widgets instead.
That clears up the screen timeout part. I was hoping there might also be a way to use the same display while the phone is upright.
