I think a 4 GB iPhone 11 (replacement for the XR) is fine. 6 GB is mandatory for the 2019 iPad Pros though, and would be nice for the OLED iPhones too. In fact, 6 GB may be necessary for the OLED iPhones because of the new tri-lens camera, but I'm not sure.4GB DRAM is just catching up to 4GB Moto G7 that has been as low as $200. For $750 starting price the iPhone Xr should really come with at least 6GB if not 8GB since it competes price wise with more feature rich Galaxy Note 10 256GB storage version.
While they're at it also put 4GB in the base iPad since it's gimped with only 2GB.
BTW, in a supposed Apple internal document leak, the new 2019 iPhones are supposed to ship with iOS 13.1, the same OS as what is running in the Geekbench entry.
