Question: what is the difference between the iphone xr and the iphone xs max?
Answer: Where there is a difference is RAM. The iPhone XS Max has 4GB RAM while the iPhone XR has 3GB. But don't worry, while multitasking may be slightly faster in a year or two, the primary reason Apple gives the XS models 4GB is to drive their dual cameras while the iPhone XR has one (more in the next section).
