Thank you for the destruction of CTOnews.com netizens and the delivery of the clues! CTOnews.com, December 20 (Xinhua)-- Apple today pushed the iOS 17.2.1 update (build number: 21C66) to iPhone users, 14 days after its last release.

It should be noted that due to the cache configuration problem of Apple node servers in various regions, the upgrade and update time may be slightly delayed in some places, usually within half an hour, not too long.

"this update contains important bug fixes and addresses battery depletion in some cases faster than expected," Apple wrote in its update log. "

"this update contains important bug fixes and is recommended to be installed by all users," it was written in the overseas English version of the update log.

According to the update log, iOS 17.2.1 is a small update that is mainly used to fix some errors and security vulnerabilities.

IOS 17.2.1 is probably just a transitional update that paves the way for the upcoming iOS 17.3. It is reported that iOS 17.3 will introduce a new "stolen device protection" security option and re-enable the ability to collaborate to create Apple Music playlists.
