It doesn’t look like much this new version of iOS available since this evening, with its anonymous number. Corn iOS 15.4.1 contains two important things. First of all, it brings battery consumption back into line: users have indeed complained that the autonomy of their iPhone has taken a hit after installing iOS 15.4.
A few days ago on Twitter, Apple support had split from a response to an iPhone owner lamenting the speed at which the device’s battery was draining. In response, the assistance had explained that the autonomy could indeed be degraded in the 48 hours following the installation of the update, the system having to adjust apps and functions.
But obviously there were other battery management concerns in iOS 15.4, prompting a tightening of the bolt with iOS 15.4.1. This update stuffy also a “0 day” flaw that could be actively exploited. Better to install this version quickly.
