The Apple iPhone 6S is going to be the very first handset from the Cupertino firm to feature a faster 2 GB LPDDR4 RAM. The iPhone 5 came with 1 GB of RAM and since then all the handsets that have arrived after it are featuring the same amount of RAM. However, the iPhone 5S came with an upgraded memory technology -- the LPDDR3 instead of the LPDDR2 1 GB of RAM present inside the iPhone 5. The LPDDR3 RAM is also present under the hood of iPhone 6 and the iPhone 6 Plus phablet.

According to G for Games, the LPDDR4 RAM was expected to arrive on the recent iPhone 6 models that came out in September 2014. However, it did not happen. The LPDDR4 is twice faster than the predecessor RAM technology: the LPDDR3 RAM. Also, it consumes less power. Speculations have it that the Apple did not feature the LPDDR4 RAM on iPhone 6 models because of its high price and low production that could not have met the high demand for iPhone 6 and iPhone 6 Plus units. G for Games adds that the LPDDR4 is 35 percent costlier than the predecessor RAM technology.

The next edition of Apple smartphone that is rumoured as iPhone 6S is expected to arrive with 2GB of LPDDR4 RAM. It has been revealed Apple will be hiring Hynix, Samsung and Micro-Elpida to manufacture the LPDDR4 RAM for the next iPhone.

Hynix is expected to manufacture 50 percent of the 2 GB LPDDR4 RAM, 30 percent of the new RAM units will be built by Samsung and lastly Micron-Elpida will handle the remaining 20 percent order. It adds among the three, Microsn-Elpida was the one that had faced low production issues but there is no such issue now. G for Games says that because of this very reason Apple is considering to use 2 GB LPDDR4 RAM on iPhone 6S.

Apple has not confirmed anything on the usage of LPDDR4 RAM on iPhone 6S. In fact, the name of the next iPhone has not been announced yet. Apple is also rumoured to be working on a 4-inch iPhone called the iPhone 6 Mini.
