No battery percentage shown on task bar for iPhone 11??!

battery percentage is only available on the following iPhones:

• iPhone 13, iPhone 13 Pro, and iPhone 13 Pro Max.
• iPhone 12, iPhone 12 Pro, and iPhone 12 Pro Max.
• iPhone 11 Pro and iPhone 11 Pro Max.
• iPhone XS and iPhone XS Max.
• iPhone X.

I'm assuming you're upgraded to iOS 16?

I can't disagree with you, it seems a little odd.
