The iPhone 18 may get a big redesign you won’t be able to see

The design of the iPhone can only be described as iconic. That rectangular shape has been a major influence on phone aesthetics and design since the first iPhone came onto the market back in 2007, and that isn’t likely to change. The internal design of the iPhone might radically shift, however. Apple is supposedly planning to change how the iPhone hardware is designed to accommodate better AI performance.

Essentially, Apple wants to use discrete memory rather than integrated memory. Those are technical terms that basically mean separate and together. On the internal system on a chip (SoC), any memory that is stacked on top is considered integrated memory. Discrete memory would be RAM that is packaged separately from the SoC. If reports are correct, Apple will begin using discrete memory in 2026, and the shift would result in faster memory and better AI performance, according to The Elec.

The current integrated memory build was introduced with the iPhone 4, and it quickly became a fan favorite because it resulted in a much more compact build. However, it also means there are fewer connection points and, therefore, lower speeds.

By swapping to discrete memory, the iPhone 18 (the first model likely to see this change) could transfer more data at a higher rate of speed. An added bonus is that separating the RAM from the SoC can mean better heat regulation. Given the amount of energy used to perform on-device AI calculations, the phone will likely generate a lot of heat.

Unfortunately, unless the iPhone begins to get physically larger, a few things will have to shrink in size. Namely, the battery. Battery technology is advancing quickly, but reliable battery life is still a struggle for phone manufacturers. If Apple has to shrink the size of the iPhone 18’s battery to accommodate a greater amount of RAM, overall usage time could take a hit.

Will my iPhone get iOS 26? Here’s every supported model
We've got the full list of iOS 26 supported devices - find out if you're getting the new iPhone update
iOS 26 features on a series of iPhone screens

Apple announced iOS 26 at WWDC 2025, and the new iPhone update comes with a fresh new 'Liquid Glass' look and plenty of features - and there are loads of iOS 26 supported devices, which is great news.

And no, you haven't missed a volley of updates since iOS 18 in 2024. Apple has skipped a bunch of numbers, so instead of giving us iOS 19 in 2025, we got iOS 26 alongside iPadOS 26, macOS 26, watchOS 26 and tvOS 26. In short, Apple's brought its operating system numbering into line. Nice.

3 big iOS 19 changes that I hope Apple reveals at WWDC 2025

We’re less than two days away from Apple’s big WWDC 2025 keynote, where the company will reveal new versions of each of its software platforms. One of the biggest changes this year is the expected shift from iOS 19 to iOS 26, with new versions of macOS, iPadOS, tvOS, watchOS, and visionOS also set to follow suit. We're also expecting to see the evolution of Apple Health, including a new AI doctor and Health subscription.

iOS 26, if it is to be named that, is expected to introduce one of the biggest evolutions in design for Apple software since the first iPhone was launched. Inspired by visionOS and the Apple Vision Pro, it’s expected to be a monumental redesign, but I hope that Apple also takes the time to make a few improvements.

iOS 26 rumored to go back to basics with four intriguing upgrades

In just two days from now, Apple will take the stage at WWDC 2025 and showcase the big yearly upgrades for its entire software portfolio. I am quite excited about the platform-wide design update and a few functional changes to iPadOS, especially the one targeting a more macOS-like makeover for the iPad’s software. 

Of course, analysts will be keenly watching for Apple’s next moves with AI, but it seems some of the most dramatic features have been pushed into the next year. Apple can afford some of those delays, as long as the company serves enough meaningful updates to its user base. Apple won’t exactly be running dry on AI, though.
