Apple are rather infamous for not revealing the RAM or Battery tech specs for their devices. Instead we find out from sites like Forbes and GSMArena that that the iPhone XS and iPhone XS Max have 4GB RAM while the iPhone XR will have 3GB of RAM. All of them will utilize Apple’s new 7nm A12 Bionic Chipset with Neural Engine for more AI (Artificial Intelligence) driven features along with dual SIM (nano + eSIM) connectivity.
