6+ really isn't my cup of tea despite better specs and premium features. It is huge. Humongous.
IMHO Apple made a mistake by giving premium features to its larger phone. You need to have your flagship phone in one size Apple. Some people just prefer smaller phones and don't want to feel like they're not buying the latest and greatest. I'm still struggling to settle with buying a 4.7" phone and you're cutting away features? Mistake. Don't underestimate small phone wanting people looking at Samsung Note etc. (phablets) sales.
- Better battery
- Better screen (more ppi)
- Horizontal use just like the iPad (and apps take advantage of it too)
- Possible better RAM (waiting for ifixit teardown this Friday for confirmation)
The bigger screen I can understand that is already big enough of a differentiating factor and with that comes more room for a battery housing.
But if infact the 6+ has 2GB ram and the 6 just 1gb ram it is a real slap in the face to people who don't want a giant iPhone but would like to have sufficient ram and we all know there is enough room in both models to have 2gb of ram
