Show battery's time recharge to 100% in iPhone's lock screen?

Is there a way to show battery’s recharge time to 100% on my iPhone 12 mini’s iOS v26.2 locked screen? So, I don’t have to unlock and click on settings’ battery to see its details?

Thank you for reading and hopefully answering soon. :)

When my iPhone (26.2) is connected to a charger, the lock screen shows time to 80% then switches to time to 100% after 80% is reached.

I only see the optimized charging overnight, but no estimated time to 80% and 100% in my old 12 mini. :/

All I can think of now is to set a stopwatch, on the 12 or otherwise, and observe the device to find out how long it takes to reach 100%. Maybe a Shortcut could be built to make a sound happen when the battery reaches 100%. Even then, I’m not sure the time it takes to 100 would be consistent over time. As I understand it some fancy stuff is going on out of users control with battery charging. But even those ideas don’t do what you’re seeking if I understand right.

Mine is variables. Like right now in iOS v26.2’s settings’ battery. It says it will take 23 minutes to charge from 88% to 100% during daytime. It doesn’t say slow charge or anything. iPhone isn’t hot too.

Woah, I see it in v26.2.1 but only for a second. It would be nice if it was up longer than a second like forever during recharge.
