“When the iPhone 6 and iPhone 6 Plus were announced, many Android fans laughed at the “pitiful” 1GB of RAM of Apple’s flagship smartphone, when Android flagships tended to ship with 2GB and sometimes more. But specs don’t always — or even most of the time — tell the whole story. As it turns out, an iPhone 6 with 1GB of RAM runs much faster than a similarly specced Android smartphone with 2GB of RAM. And it all has to do with the fundamental difference in the way iOS and Android handle apps.” [1]
