**iOS 12.3.1 Update Released**

For everyone who has iOS 12.3 or any device that supports iOS, there is now an update available. This update is significant as it brings iOS 12.3 to version 12.3.1, which is the latest stable release for devices running this operating system.

The update comes in at approximately 77.9 megabytes on my iPhone X and will vary depending on the device you are using. It's essential to note that if you're currently running iOS 12.4 beta software and want to go back to version 12.3.1, you'll need to plug your device into a lightning cable and then connect it to iTunes to perform the downgrade. Without the IPSW file, you won't be able to downgrade, so patience is advised until the next beta or final version of iOS 12.4 is released.

The build number for this update is 16F203, which indicates that it's a point-one release addressing minor issues. The first issue it fixes is related to voice over LTE or multi connectivity on certain phones, where it wouldn't work properly. This should resolve the issue for users experiencing problems with these connections.

Another issue addressed by this update is in the Messages app. When filtering out unknown senders from the conversation list, messages from unknown senders would sometimes appear in the main text messaging window, even though they were supposed to be filtered out according to the settings. This has been fixed, ensuring that messages from unknown senders only appear in the junk section.

Furthermore, this update also fixes an issue related to the "Report Junk" feature in Messages. It had a tendency to not show up on certain devices, which should now be resolved with the latest version of iOS 12.3.1.

**Modem Updates for Newer Devices**

While there are no new security updates available for this release, modem updates have been released for newer devices such as the iPhone 8, X, XS, XS Max, and XR. These updates aim to fix issues on these devices, so they should now work more efficiently than before.

**Battery Life**

iOS 12.3's battery life was reported by the author of this article to be relatively good, with approximately five and a half to six hours of screen time on their device prior to testing iOS 12.3.1. However, since it has only been out for about an hour or more when this video was recorded, actual results may vary.

When putting the newer iOS 12.3.1 through its paces on the author's XR, it showed a battery life of 4 hours and 32 minutes with one hour and 22 minutes of screen off time. When compared to the original iOS 12.3, there was a noticeable difference in terms of actual battery performance.

**Geekbench Scores**

To get an idea of the overall performance of these devices running iOS 12.3.1, some Geekbench scores were taken. The iPhone X scored 4246 for single-core and 10,066 for multi-core, indicating its relative performance capabilities. The iPad Pro 12.9, which also ran this update, showed much higher scores in the multi-core tests, at 17,535.

The older devices, such as the iPhone X and 8 Plus, should perform similarly or just as well as these newer versions, given that this is more of a maintenance update with bug fixes rather than any significant performance enhancements.
