iOS 16.4 official version is released, it is recommended to upgrade!

Early this morning, Apple pushed the official version of iOS 16.4 to all iPhone users. Users who want to upgrade can directly open Settings-General-Software Update and upgrade to the latest official version of iOS 16.4 online OTA.

The size of this official update package is 5.4G, and the internal version number is (20E247). As the fourth major version update of the iOS 16 system, what new features does this official version of iOS 16.4 bring?

According to Apple's official update document, the main updates of iOS 16.4 include:

In addition to the above updates, the official version of iOS 16.4 also includes the following updates:

Added "Test Update" feature

According to feedback from users who have upgraded, the iOS 16.4 beta version has quite a lot of updates. First, Apple has added a "beta update" option in iPhone's Settings-General-Software Update, making it easier for beta users to choose whether to upgrade to the latest beta or public beta.

Apple said that starting with the iOS and iPadOS 16.4 beta, Apple development testers will be able to enable developer betas directly in the software update settings... See the picture for details:

In addition, Apple also emphasized that in future versions of iOS and iPadOS, this new setting will be the way to enable developer betas, and configuration profiles will no longer grant access.

​To put it simply, the method of upgrading to the beta version by installing a description file may not work in the future. iPhone users who want to upgrade to the beta version must first use their Apple ID to register a developer account on the Apple Developer website before they can receive Beta version update push notifications.

Supporting 5G for broadcasting and television

According to feedback from friends who use China Radio and Television SIM cards, after upgrading to iOS 16.4, China Radio and Television's SIM cards already support 5G networks. Users can first open Settings-General-About this device, update the operator configuration, and then choose to use 5G network in the cellular network.

Warranty Check Upgrade

The "Warranty Status" function in this device has also been upgraded. Now in addition to checking the warranty status of the iPhone itself, you can also directly check the warranty status of devices connected to the iPhone (such as Apple Watch, AirPods, etc.).

​New Safari web page notifications

iOS 16.4 allows websites added to the iPhone or iPad home screen to send web push notifications, similar to notifications on the Mac. Users will be prompted to give web apps permission to send notifications , and notifications can be managed for each web app in the Notifications section of the Settings app.

As early as last June at the WWDC conference, Apple announced that it would add this new feature to iOS 16, but it was not officially added until today's iOS 16.4 push. It should be noted that in order to receive push notifications from a website, not only do you need to add it to the home screen, but web developers must also add support for this feature.

At the same time, notifications from home screen web apps can also be displayed in the daily summary in focus mode, and web apps added to the home screen can also display badges to let users know about alerts and notifications.

New "Filter Conditions" added to Focus Mode

When setting the focus mode, a new "Filter Conditions" option is added at the bottom. Users can manually add some App and system function filters, including calendar, Safari, low power mode, all-day display, dark mode, etc.

HomeKit Architecture Regression

Apple also reintroduced the HomeKit architecture update in iOS 16.4, iPadOS 16.4, and macOS Ventura 13.3. It was previously removed in iOS 16.2 due to numerous vulnerabilities. The new HomeKit architecture improves the reliability and efficiency of communication between smart home accessories and Apple devices.

Since the RC version released last week has a different version number from the official version of iOS 16.4, this also means that even if you have upgraded to the official version last week, you can now upgrade to the official version online OTA without flashing the phone.

It is recommended that all iPhones that have been upgraded to the iO​S 16 system can be upgraded to the latest iOS 16.4 official version. As for the signal and battery life performance, further testing is needed. The editor will share relevant test data with you later~

In addition to the official version of iOS 16.4, Apple also pushed the official version update of iOS/iPadOS 15.7.4 for devices that cannot be upgraded to iOS 16 and iPadOS 16. This version does not have major functional improvements, but only bug fixes and optimizations.
