iPhone 18 Expected to Get Major Upgrade in Key Specifications

Key Takeaways

1. The entry-level iPhone 18 may receive a 50% increase in RAM, potentially reaching 12 GB.
2. Apple is sourcing LPDDR5X RAM from suppliers like Samsung, SK Hynix, and Micron for the iPhone 18.
3. The current iPhone 17 has 8 GB of RAM, while the iPhone Air, 17 Pro, and 17 Pro Max have 12 GB each.
4. Increased RAM is necessary to support enhanced AI capabilities in future iPhone models.
5. The official reveal of the iPhone 18 is expected in Fall 2026.


The iPhone 18 could be significantly improved in its capability to run Apple Intelligence.

According to a report from Korean source The Bell, MacRumors has shared that the entry-level iPhone 18 may see a 50% increase in RAM. The Bell indicates that Apple has approached suppliers such as Samsung, SK Hynix, and Micron to order more LPDDR5X RAM for next year’s iPhone models. It’s important to mention that Samsung currently offers LPDDR5X RAM only in 12 GB or 16 GB options.

Potential RAM Increase

If this upgrade occurs, the base iPhone 18 would feature 12 GB of RAM, aligning it with the more advanced Pro versions and the possibly forthcoming (though unlikely) iPhone Air 2. For context, the existing iPhone 17 is equipped with just 8 GB of RAM, while the Air, 17 Pro, and 17 Pro Max all have 12 GB of RAM each.

Speculation and Future Needs

Naturally, this information remains speculative and should be viewed with caution. Nonetheless, as Apple continues to enhance its Apple Intelligence (its unique AI offering) and on-device AI capabilities, the smartphones will require additional RAM. While 8 GB of RAM is likely adequate for the majority of users and their everyday needs, AI applications are known to be very demanding on memory, so advancing the base iPhone 18 to 12 GB of RAM to support an on-device model seems reasonable.

We will find out for sure when Apple officially reveals the iPhone 18, which is expected to happen in Fall 2026.
