I want my battery heath to bring percentages

Hi Teefund,

Welcome to Apple Support Communities. It looks like you'd like to see your battery percentage on your iPhone 11 Pro Max. We'd like to help.

iPhone models with Face ID show the battery percentage in the Control Center rather than on the display. Check out this resource to get that information on your iPhone: Show the battery percentage on your iPhone, iPad, or iPod touch

Find battery percentage on iPhone 13 and other models with Face ID

On iPhone 13 and other iPhone models with Face ID (iPhone X and later), the battery percentage appears in Control Center. Just swipe down from the top-right corner of your display.

If you're like to see this information in the Menu bar, you can leave product feedback for that here: Product Feedback

Hope that helps.

Cheers!
