We are still far away from the official announcement of Apple's next-gen iPhones. Over the last few days, we have heard a lot of things regarding the new iPhones, including the possible delay of iPhone 8 until 2018, while the iPhone 7S and iPhone 7S Plus are on track.
An analyst firm Trendforce has now published its predictions, saying that phone will have 3.2 GB RAM on average by the end of 2017, which is a decent increase over 2016's 2.4 GB. The report also predicts that the 10th anniversary iPhone, also known as iPhone 8, will have no more than 3 GB RAM, 4.7-inch iPhone 7s will retain 2 GB of RAM, while the larger 5.5-inch iPhone 7s Plus will maintain 3 GB.
One of the main reasons behind this is due to the rising prices of DRAM and NAND. To be honest, iPhones perform really well with the current amount of RAM, but we'll have to wait to see if Trendforce's predictions are correct.
