Apple has rolled out iOS and iPadOS 15.4.1, an update that fixes several accessibility bugs, enhances security and resolves a power drain bug that affected some people’s phones and iPads after updating to iOS 15.4.
It’s unknown how common the problem was, but earlier this month, Apple Support’s Twitter account informed users experiencing battery loss that it was “standard for your applications and functions to require adjustment up to 48 hours following an upgrade.” Even more than two weeks after the update’s release, it’s not difficult to locate current threads complaining about low battery life.
Even if your battery has been functioning normally, it may be worthwhile to update it as soon as possible. According to Apple, iOS 15.4.1 contains security updates for problems that may have been abused in the wild. Unfortunately, this type of warning has become rather common in Apple’s security advisories, and although putting off upgrades forever is never a good idea, it appears that it’s more crucial than ever to ensure your devices are running the most recent version of their operating system.
To update your iPhone with the latest 15.4.1 upgrade, you can go to Settings > General > Software Update. In addition, to update your Mac with the latest upgrade, go to System Preferences > Software Update.
