The base iPhone 18 model that Apple is expected to release by March 2027 will be equipped with 12GB of RAM, up from 8GB in the iPhone 17, according to analyst Jeff Pu.

Pu’s latest assessment conflicts with the most recent report on the subject from analyst Ming-Chi Kuo, who said both the iPhone 18 and iPhone 18e would have only 9GB of RAM.
However, Pu agrees with Kuo that the lower-cost iPhone 18e – also coming in the spring – will come with 9GB of RAM, based on his own sources and supply chain information. Both models are expected to be powered by the A20 chip.
Interestingly, Pu additionally believes that the regular iPhone 18 will feature a narrower Dynamic Island. Most of the rumors about a smaller Dynamic Island have pertained to the iPhone 18 Pro models, but Chinese leaker Ice Universe has also claimed the smaller Dynamic Island will be adopted across the iPhone 18 lineup.
