The remainder of the changes that will be introduced in iOS 16.4.1 are uncertain, but there are some clues. Some users have reported their phones heating up while charging, as well as decreased battery performance. While some in the Apple Community forums suggest that this may be a feature and not a bug, as the device may take up to 48 hours to complete all necessary background tasks post-update, others point out that battery drain has been a persistent issue since the launch of iOS 16, suggesting that it may be an oversight on Apple’s part.
