iPhone's Battery Symbol - UI/UX failure?

iOS 16 battery symbol, flat inside and the % within. 

It's ok, but not so clear when it's in charging mode. 

Have to keep the batter widget on the screen to see the progress. It looks ok, may be if the % inside is set to exclusion or division or empty to see background, it can be more visible. As of now light green and text white while charging has less visibility than while it's not. 

​Hope they can fix it.
