iOS 18 vs. iOS 18.1: Here's How the Two Updates Compare

As a result of the first Apple Intelligence features being delayed, iOS 18 and iOS 18.1 are currently in beta testing simultaneously.

Generic iOS 18 Feature Real Mock
Below, we explain the differences between the two upcoming software updates, including new features and estimated release timing.

New Features

iOS 18.0

iOS 18 introduces new customization options for the Home Screen and Control Center, a redesigned Photos app, numerous enhancements to the Messages app, an option to lock apps behind Face ID or Touch ID, and much more.

The highlight of iOS 18 is Apple Intelligence, but the rollout of these artificial intelligence features was pushed back to iOS 18.1.

Read our in-depth iOS 18 roundup to learn more about the update.

iOS 18.1

The first iOS 18.1 developer beta added some Apple Intelligence features for testing, including new writing tools for generating and summarizing text, suggested replies in the Messages app, email summarization, phone call recording and transcribing, and a few others.

Apple Intelligence General Feature
The third iOS 18.1 developer beta added a few more Apple Intelligence features, including a "Clean Up" tool in the Photos app that "can identify and remove distracting objects in the background of a photo," and notification summaries for additional apps beyond Mail and Messages.

Apple Intelligence features that are still not available to try include Image Playground for custom-generated images, Genmoji for custom-generated emoji, and several enhancements to Siri, including ChatGPT integration, richer language understanding, deeper per-app controls, on-screen awareness, and personalized context.

Release Timing

iOS 18.0

iOS 18 will likely be released in mid-September, based on the timing of previous major releases:

  • iOS 17: September 18, 2023
  • iOS 16: September 12, 2022
  • iOS 15: September 20, 2021
  • iOS 14: September 16, 2020

iOS 18.1

iOS 18.1 will likely be released in late October, based on the timing of previous similar updates:

  • iOS 17.1: October 25, 2023
  • iOS 16.1: October 24, 2022
  • iOS 15.1: October 25, 2021
  • iOS 14.1: October 20, 2020

Latest Versions

As of August 28 at 12:55 p.m. Pacific Time, the latest iOS 18 and iOS 18.1 betas are as follows:

How to Install Betas

Developer Betas

iOS 18 and iOS 18.1 are both available as developer betas.

To enroll in Apple's developer beta program, visit developer.apple.com, sign in to your Apple ID, and accept the terms and conditions of the Apple Developer Agreement.

Since 2023, installing iOS developer betas no longer requires being enrolled in the Apple Developer Program for $99/year. Anyone with an Apple ID can accept the Apple Developer Agreement and access the betas for free.

After accepting the agreement, open the Settings app on your iPhone and tap General → Software Update → Beta Updates. This is where the iOS 18 and iOS 18.1 developer betas are listed, and you can tap on one to begin the installation process. Note that the iPhone must be signed in to the same Apple ID set up as a developer account.

Due to software bugs and other potential issues, we recommend installing the iOS 18 or iOS 18.1 betas on a secondary iPhone, rather than the device that you use daily. We also highly recommend backing up your iPhone to your Mac before installing beta software on the device, to prevent data loss in the event something goes wrong.

Public Betas

iOS 18 is available as a public beta, but iOS 18.1 is not currently.

To enroll in Apple's free public beta program, visit beta.apple.com, sign in to your Apple ID, and accept the terms and conditions.

After signing up, open the Settings app on your iPhone and tap General → Software Update → Beta Updates. This is where the iOS 18 public beta is listed, and you can tap on it to begin the installation process. Note that the iPhone must be signed in to the same Apple ID enrolled in the public beta program.

We also highly recommend backing up your iPhone to your Mac before installing beta software on the device, to prevent data loss in the event something goes wrong.

The first Apple Intelligence features are now available to test ('https://www.macrumors.com/2024/07/29/ios-18-1-apple-intelligence-features/') in the iOS 18.1 developer beta, which is only available for the iPhone 15 Pro and iPhone 15 Pro Max currently.
I really want to be excited for Apple Intelligence, but between it being available only for the latest phones, and Apple being behind on AI compared to a lot of other companies, I get the feeling it'll be a while before it's something most people can really enjoy. 😩

Seeing that iOS 18 has so many radical changes, the likelihood that lots of stuff will be broken makes me not want to buy a new phone - since it will come with it pre installed. Too much aggravation.

I see ZERO reason to install iOS18 ever
As they decided to make me buy a new phone to use the AI features, and that is what I really wanted, why would I install this on my 13 pro max.
Nonsense.
Eventually I will upgrade my phone, but this was a garbage way to force upgrades on people in a crap economy.

New iOS versions have been flaky in general, and there also tend to be more hardware manufacturing issues in the initial batches (e.g. screen quality issues). It’s a good idea to upgrade mid-cycle, there’s no reason to rush, and moreover you won’t have to pay full price then.
I agree with you about there being no reason to rush, and yes, by mid-cycle, manufacturing issues have been worked out, as well as a lot of software bugs. But I don't get your statement about not having to pay full price then. iPhones don't reduce in price by mid cycle. An iPhone 15 costs the same today as it did the day it was released. Previous versions of phones will be reduced in price a bit, but not at mid cycle.
