iOS 15.4.1 is released with minor bug fixes and an important security update

Apple has released iOS 15.4.1 and iPadOS 15.4.1, a minor update to iOS 15.4 that fixes a few bugs. Interestingly, Apple Support just recently explained that battery drain is normal and expected for a short time after an iOS update, but this release fixes a problem where battery drain may be excessive on some devices after updating to iOS 15.4. I guess it wasn’t that typical this time after all?Other fixes include an issue with braille devices become unresponsive or some MFi hearing device
