Apple fixes iOS battery drain bug with 15.4.1 update

Apple has released iOS and iPadOS 15.4.1, an update that fixes some accessibility bugs, improves security, and fixes a battery drain bug that plagued some people’s phones and iPads after they were updated. updated to iOS 15.4.

It is unclear how widespread the problem was (no one on the Edgestaff reported noticeable battery issues), but earlier this month the Apple Support Twitter account told customers complaining of battery drain that it’s “normal for your apps and features to need to adapt for up to 48 hours after an update.” Still, more than two weeks after the update was released, it’s not hard to find recent posts reporting poor battery life. Hopefully the update fixes those issues – iOS 15.4 brings the very handy update of being able to use Face ID while wearing a mask, so it would be a shame if people didn’t want to update for fear of battery issues.

Even if your battery was working fine, it might be worth updating it fairly quickly. Apple says iOS 15.4.1 (and macOS Monterey 12.3.1, also released today) contain security fixes for issues that Apple says could have been exploited in the wild. Unfortunately, this type of warning has become quite common in Apple’s security bulletins. While postponing updates indefinitely has never been a good idea, it seems more important than ever to make sure your devices are running the latest version of their operating system.

To update your iPhone, go to Settings > General > Software Update. To update your Mac, go to System Preferences > Software Update.
