| |

Apple has released iOS 15.4.1 and iPadOS 15.4.1 updates for its devices in just over two weeks after the debut of iOS 15.4 and iPadOS 15.4. The new software versions fix battery drain issues that were introduced with the release of the previous iOS and iPadOS updates. Alongside iOS 15.4.1 and iPadOS 15.4.1, Apple released the HomePod 15.4.1 update to fix an issue related to Siri. Apple Watch users have also received watchOS 8.5.1 as a minor update that brings a number of security fixes. Similarly, Mac users have received macOS Monterey 12.3.1 with fixes to address Bluetooth and external display connection issues.

iOS 15.4.1, iPadOS 15.4.1: What’s new?

Last month, Apple introduced iOS 15.4 and iPadOS 15.4, which caused battery drain issues for some users. User reports surfaced online suggested that the issues reduced battery life on the iPhone 13 Pro Max to half a day for some users, while the iPhone 11 models lost 80 percent of the battery in 24 hours for some users. Apple has addressed those concerns through the introduction of iOS 15.4.1 and iPadOS 15.4.1, which include fixes for the issues that cause batteries to drain faster than expected, the official said Release Notes.

In addition to battery drain issues, iOS 15.4.1 and iPadOS 15.4.1 fix a bug that caused braille devices to become unresponsive when navigating through text or displaying an alert. The updates also fix an issue related to Made for iPhone and Made for iPad hearing aids that became unresponsive with some third-party apps.

Separately iOS 15.4.1 and iPadOS 15.4.1 fix a security issue within the AppleAVD media decoder that would allow an attacker to run arbitrary code with kernel privileges. Apple has mentioned that the zero-day vulnerability could be “actively exploited” by some attackers in the wild. It affects devices namely iPhone 6s and later, iPad Pro (all models), iPad Air 2 and later, iPad 5th generation and later, iPad mini 4 and later and iPod touch (7th generation).

HomePod software version 15.4.1: What’s new?

Alongside the latest iOS and iPadOS versions, Apple has released HomePod software version 15.4.1, which fixes an issue that causes some HomeKit-enabled accessories to become unresponsive when controlled via Siri. The update also includes bug fixes for the company’s HomePod devices called in his changelog.

watchOS 8.5.1: What’s new?

Apple also released watchOS 8.5.1 as a minor update to watchOS 8.5. The new software version includes security updates and bug fixes for compatible Apple Watch models, the company said. Exact details about the security updates and fixes are not yet known.

macOS Monterey 12.3.1: What’s new?

Mac users have received the macOS Monterey 12.3.1 update that fixes an issue that causes Bluetooth devices, such as game controllers, to disconnect after playing audio through some Beats headphones. The update also fixes an issue that caused the USB-C or Thunderbolt external display not to turn on when connected to the Mac mini (2018) as a second display.

The new version of macOS Monterey also fixes the issue that caused some 2021 MacBook Pro models not to update or restore to macOS Monterey 12.3, Apple called in its release notes.

Additionally the version macOS 12.3.1 carries two security fixes. One of them concerns the zero-day vulnerability related to the AppleAVD media decoder, which also existed for iOS and iPadOS users. The software update also fixes a vulnerability that existed within the Intel graphics driver that could allow an attacker to access kernel memory.

Apple said it was aware that both issues may have been actively exploited.

How to download iOS 15.4.1, iPadOS 15.4.1

You can download iOS 15.4.1 or iPadOS 15.4.1 to your device by going to settings > General > software update. The updates are available for all devices running a recent version of iOS 15 or iPadOS 15.

The updates also reach your devices automatically if you have activated the auto-update function. However, Apple typically delays seeding updates for devices set to auto-update.

Craig Federighi, Apple SVP of Software Engineering apparently confirmed in a reply to a Reddit user, the delay in automatic updates. The manager said in his alleged response, shown in a screenshot, that the company delays automatic updates for one to four weeks after receiving user feedback and makes its software updates available first to users who opt for the manual method.

Federighi’s supposed answer doesn’t provide any clarity as to why Apple is doing this. However, this can have two reasons. First, the delay would help the company not put a massive strain on its servers to push software updates to a large number of devices at once. Second, it can help reduce the impact of any bugs that an update might contain.

How to download HomePod software version 15.4.1

Unlike iPhone and iPad devices, Apple automatically pushes software updates to HomePod and HomePod mini. However, you can check for the HomePod software version 15.4.1 for your device by going to Home Settings > software update from the Home app. Make sure your connected Apple device is running the latest software version.

How to download watchOS 8.5.1

You can download watchOS 8.5.1 on Apple Watch Series 3 and later by going through General > software update in the Watch app on your iPhone. Alternatively, you can download the update directly from your Apple Watch when connected to Wi-Fi by going to settings > General > software update.

How to download macOS Monterey 12.3.1

Apple has released macOS Monterey 12.3.1 for all eligible MacBook Air, MacBook Pro, iMac, Mac mini and Mac Pro. You can check for the update manually by going to system settings > software update after clicking the Apple menu icon in the top left corner of your computer screen. Alternatively, you can get the update by going to the About This Mac preference in the Apple menu.
