Future 2nm chip will boost battery life, speed in iPhone 18

When Apple releases its iPhone 18 lineup, the models will move to using a new two-nanometer processor from Taiwan Semiconductor, according to one prominent analyst.

The current iPhone 16 uses a 3nm A18 processor, with the Pro models using an A18 Pro processor. Analyst Ming-Chi Kuo originally published his prediction in September of 2024, believing that the iPhone 17 — expected in fall 2025 — will use an improved 3nm chip dubbed the A19.

He added at the time that the next-generation 2nm chips would be ready in time for only the high-end iPhone 18 Pro release, which should come in the fall of 2026. Other analysts were more confident the chip would be used across the lineup.

Due to the strong test yields of the forthcoming 2nm chips, Kuo is now on board with the idea that they will be used throughout the iPhone 18 lineup. He reported that TSMC's yields on the 2nm chip are above the 60-70 percent range, according a new tweet posted on March 22. He noted that the yields hit those benchmarks three months ago, those yields are now "well above that."

Reiterating my prediction from six months ago: the 2H26 new iPhones (iPhone 18) will be powered by TSMC's 2nm chips.

Worth noting, TSMC's 2nm R&D trial yields reached 60-70% three months ago, and they're now well above that. https://t.co/ZoWXFqfUnS

Changes for the iPhone 17 and iPhone 18

While the chipmakers are focused on 2026's iPhone 18 lineup, Apple and its customers are eagerly awaiting the debut of the iPhone 17. Rumors suggest that Apple will drop the idea of an iPhone 17 Plus in favor of introducing a notably thinner model, potentially to be called the iPhone 17 Slim.

This new model would likely use the same chip as the regular iPhone 17, which is expected to be powered by the A19 chip. In addition to the performance boost of the new chip, Apple has also been seeking to use faster RAM in the next iPhone.

Accomplishing this would also help improve the responsiveness and performance of Apple Intelligence.

Cosmetically, Apple has also been said to be trying to create a bezel-free iPhone. It has come close with the current iPhone 16, but the iPhone 17 may succeed in reducing the existing bezel to near-zero in size.

In addition, Apple may use the opportunity presented by the new iPhone model to change up the suppliers of the camera sensor. Samsung has been reported to be lobbying hard for the opportunity to supply sensors for the iPhone.

When the iPhone 18 debuts, analysts expect the smaller die size of the 2nm A20 could translate to a 10 to 15 percent boost in performance over the iPhone 17, while also reducing energy requirements. If true, the latter feature could lead to better battery life for the iPhone 18 line.

With 2nm this means less power requirements. I’d think this opens some serious options for a new mini phone.

My 13 mini is still going strong but one day it will break and I sure don’t want anything bigger than this. Nor do I look forward to folding phones, whatever great breakthroughs are being made. I just don’t care. For me the mini is the sweet spot. I’d actually like it to be even smaller, like the 5S.

Ah well, it never hurts to keep dreaming, even if it’s in vain.

I’m in the same boat. My 12 Mini died last year and I bought a 16 Pro 256gb for $1100 hoping I’d just get used to the size but I hated it and returned it after 14 days. Ended up with a used 13 Mini off eBay for $350. Apple is leaving a lot of money on the table by not offering a new Mini. I’m holding this until I can’t use it anymore unless Apple releases another mini.

No one buys (enough of) the smaller iPhones, or the cheaper iPhones many people keep asking for them and from time to time over the years Apple will offer something and it doesn’t sell not even a little bit….. Apple folding phones when Apple finally gets around to offering one will suffer the same fate, particularly when the bend, fold, crease problem can’t be solved, In short it doesn’t hold up for six or seven years of continuous use/abuse.
