Apple's iPhone 6 Plus phablet also comes with 1 GB of RAM
The 5.5-incher carries roughly the same specs as its 4.7" iPhone 6 counterpart, such as an A8 processor, in-cell touch display, and an 8 MP iSight camera, but upgrades significantly in several departments. It adds more pixel density to the screen - 401ppi, against the iPhone 6's 326ppi - but also equips the camera with optical image stabilization, and provides a much larger, 2915 mAh battery, to keep the lights on for longer.
Judging from the screenshot here, however, it still keeps the 1 GB of RAM amount that the Apple iPhone 6 carries, so Apple stays true to its tradition not to overdo the iPhone's specs without a tangible reason. Given the way that iOS 8 multitasks, and the fact that all the software in the App Store runs fine with this amount of RAM, Apple's approach seems to be working, so it won't be at least until next year when we see an iPhone with more than 1 GB of RAM on board.
