iOS 17.2.1 Release Notes Mention Battery Drain Fix in Some Countries

Apple on Tuesday released iOS 17.2.1 for the iPhone, and the update supposedly improves battery life in at least some countries.

In the U.S. and most other countries, the iOS 17.2.1 release notes only mention 'important bug fixes,' and do not provide any specific details. In China and Japan, however, the notes also indicate that the update 'addresses an issue that can cause the battery to drain faster under certain conditions,' based on a computer translation of the text.

The release notes discrepancy was highlighted in a social media post on X by Brandon Butch, who runs an iOS-focused YouTube channel. We have reached out to Apple for clarification, and we'll update this story if we receive a response.

Following the release of iOS 17.2.1, Apple continues to beta test a larger iOS 17.3 update, which will likely be released in January or February. iOS 17.3 adds a new 'Stolen Device Protection' security option, and reintroduces collaborative Apple Music playlists, a feature that was originally intended to launch with iOS 17.2 last week.Related Roundups: iOS 17, iPadOS 17Related Forums: iOS 17, iPadOS 17This article, "iOS 17.2.1 Release Notes Mention Battery Drain Fix in Some Countries" first appeared on MacRumors.comDiscuss this article in our forums
