Other New iPhone Air... Always On Display Not Working

[Stingfello]

As title says. Definitely on in settings, but display going black after about 30-45 seconds. Any ideas?

Is your phone in bedtime or wind-down mode (is bedtime soon)?

Indeed! Didn't know that would cause this.

I set my iPhone Air up as a new phone (I like it clean and fresh, re-downloading and organising stuff).

I noticed the Always On display wasn't on and went into Display & Brightness settings and found it was turned off - not on by default. Not sure why this is, but once I turned it on it's worked great.
