Apple released a small iPhone software update on Thursday to fix an issue that iPhone users have been facing ever since iOS 15.4 hit the devices. Users have taken to forums, Reddit, social media platforms and Apple’s support channels to complain that their iPhones’ batteries are draining abnormally fast after updating to iOS 15.4. With the update, Apple now says the issue is fixed, along with some issues with accessibility features.

Here are Apple’s brief release notes for the update:

This update includes the following bug fixes for your iPhone:

  • Battery may drain faster than expected after updating to iOS 15.4
  • Braille devices may become unresponsive when navigating through text or displaying an alert
  • Hearing aids made for iPhone may lose connection in some third-party apps

Thursday’s update comes about two weeks after the launch of the new iPhone SE and iOS 15.4, which was likely the last major feature update before iOS 16. iOS 15.4 gave users the ability to use Face ID while while wearing a face mask, introduced a gender-neutral American English voice for Siri, and added a plethora of new emoji, among other things.

Apple also released iPadOS 15.4.1, watchOS 8.5.1, and tvOS 15.4.1. Bug fixes and security updates are important parts of today’s operating system update, but they also add support for Apple’s Business Essentials program. Apple calls Business Essentials “a comprehensive subscription that seamlessly combines device management, 24/7 support, and cloud storage.”
