My iPhone is recommending a charge limit

[DeanL]

Is this new? I’m running 18.1 bets on an iPhone 16 Pro Max and I had this notification recommending a charge limit.
I’ve never seen this before on my 15 Pro Max!

Yes, it's new in iOS 18.0. Previously, 80% was the only option.

Haven't had this on my launch day 16 Pro Max yet!

I did set it to 80% charge limit out of the box so I'm unsure I would get that notification anyway?
