Looks like some kind of accessibility setting.
This happens when text size is over 55%.

You’ve got Larger Text turned on.
Go to Settings > Accessibility > Display & Text Size > Larger Text.
If it’s on and the slider is past halfway, you’ll see a big text box when you tap the clock or battery. Helps people with vision issues.

It was a setup all along.
That’s actually really useful for people with bad eyesight.
What kind of sorcery is this?
What you’re looking at… is an iPhone.
Am I the only one wondering how OP got that scar on their hand?
A phone…?
Still waiting for someone to confirm the real answer.

Checked my settings. The battery percentage thing is separate from accessibility, but my iPhone 14 on iOS 18 has been doing this for a while now.
That wallpaper looks nice, anyone got a link?

Might be the new Black Unity wallpaper. Should be available in a software update soon.
