Briefly: While Apple showed off most everything about the new iPhones last week, it didn't tell us about one thing: how much RAM is crammed inside the new phones. Thanks to some clever sleuthing in Xcode, we now know the numbers.
Not much of a surprise but Xcode confirms 2GB of RAM for the 6s (and 6s plus), and 4GB for the iPad Pro pic.twitter.com/X8Ym4DtamS

2GB is the obvious upgrade from the 1GB found in the 6. It's not going to win the specs war against the 3GB of RAM you'll find crammed into top-end Android phones, but that's not made iPhones run slow in the past.
