Apple has not officially disclosed the amount of memory (RAM) that the iPhone will have. Therefore, it will be clarified later by disassembling iFixit and so on.
Introducing the US media 9to5Mac, which summarizes the types and capacities of RAM from the original iPhone to the current iPhone 13 series.
Why Apple doesn’t disclose RAM capacity
Why doesn’t Apple list the RAM capacity of the iPhone in the spec table in the first place? 9to5Mac explains that there are multiple reasons, and the biggest reason is that there are many cases where the performance of Android smartphones with a large amount of RAM exceeds the performance of iPhones with a small amount of RAM.
By optimizing both hardware and software, Apple has achieved high efficiency and performance even with a small amount of RAM.
Below is a list of RAM capacities installed in successive iPhones.
