Following user reports of heavy battery drain on the recently launched iOS 15.4, Apple has rolled out iOS 15.4.1 to the public with a solution for the battery issue. The iOS 15.4.1 release notes also mention some bug fixes for braille devices and Made for iPhone hearing devices. However, as always, upon closer inspection, you would come across other minor changes too. For instance, the Apple world clock widget now shows the Ukraine capital Kyiv’s abbreviation as KYI instead of KIE. Let’s know its reason first.

As Steve Moser, contributing writer at Macrumors notes, “KIE comes from the Russian spelling of Kyiv: Kiev.”

Also, Ukrainian President Volodymyr Zelenksyy recently clarified the correct spelling of the nation’s capital. He tweeted:

High time to finally discard the outdated Soviet spelling of our cities and adopt the correct Ukrainian form. Grateful to Japan and @kishida230 for already doing so and encourage others to follow. #KyivNotKiev
