Apple iPhone 6 is going to be released next month and there are a number of tumors that what it might feature and what will it be look like. According to a recent image posted by a trusted Chinese source Weibo there is a reason to believe that iPhone 6 will have only 1 GB of RAM just like iPhone 5 and 5S.
Some of the Android phones today have 3 GB of RAM and they are are said to reach 4 GB this year. Windows Phone has also reached 2 GB of RAM. And in this world Apple is going to release its next smartphone with only 1 GB of RAM. But when it comes to optimization, Apple phones do not hang as Android phones do even with 2 GB of RAM. But iOS 8 will offer developers to develop more bigger and heavier apps so we have to see how do they optimize their apps to run smoothly on 1 GB of RAM.
There is a strong possibility that Apple will release two versions of iPhone 6 this year. Both will have different battery capacities and different screen sizes. So there is a possibility that both of iPhone models will have different amount of RAM. But we have to wait to see.
