iOS 18.4 Coming Soon With These New Features for Your iPhone

Apple is expected to release iOS 18.4 to the general public as soon as next week, following more than a month of beta testing.

Generic iOS 18
Apple's website says some iOS 18.4 features will be released in "early April," so the update should be out as early as Tuesday, April 1.

Apple this week seeded the iOS 18.4 Release Candidate, which is typically the final beta version, barring the discovery of any major last-minute software bugs. iOS updates are typically released one week after the Release Candidate, and next week will be early April, so that would align with the timeframe that Apple has provided.

There is always a possibility of a Release Candidate 2, however, which could push back the release schedule by up to one more week.

iOS 18.4 is compatible with the iPhone XS series and newer, and it will be available in the Settings app under General → Software Update once it is released.

While the personalized Siri features that were originally expected to launch as part of iOS 18.4 have been delayed, the update still includes a handful of new features. There are a few Apple Intelligence additions, including Priority Notifications, along with an Ambient Music feature in Control Center, new emoji options, support for lossless audio and low-latency audio on AirPods Max with a USB-C port, and more.

Other software updates like iPadOS 18.4, macOS 15.4, watchOS 11.4, tvOS 18.4, visionOS 2.4, and more should also be released as soon as next week.

Where did you read this? I hope it’s true. If they can have their own private compute and claim that it is completely safe, then they ought to go that route for Siri. Yes, on device is great, especially when you don’t have Internet, but private cloud compute may be the answer to really getting Siri going. If you still have the info source, please share.

Apple will probably use those server racks to implement Siri LLM, which they might introduce with this fall's OS updates (iOS 19, etc.), but as you say, fuller implementation isn't supposed to happen until spring 2026. But the current/long-standing problems with Siri that people experience don't involve needing more server processing power, but rather are due to poor implementation of its on-device capabilities. But the latest rumor is that Apple may be planning to hand off some of Siri's tasks that have until now been handled on-device, to this Siri LLM, so it'll be interesting to see how much of that happens.

A mere month of "beta testing"?

I think we all know it'll end up the usual 6 months post-release until iOS 19, then rinse and repeat.

Every release more emoji’s! It’s Apple’s virtue signaling that innovation is dead.
