Your wish may come true…
iPhone 14 will have a smaller obstruction on the top of the display, replacing the notch.
With the added space it creates, maybe, just maybe. Apple will bring the battery % icon back on a future version of iOS.
In the meantime, a workaround is to use the gigantic battery widget on your Home Screen. I have an 8 Plus that still has the battery % indicator on the top but I still use the giant battery widget too.
