Should i buy an iPhone 6s Plus iPhone 6s iPhone SE iPhone 6 What's the difference? - 1

6s is the most modern of the 3
technically there all just the 6 but the 6s has force touch as does the 7 and the 8, the 6 and the SE do not support force touch and force touch is a big part of IOS now

The 6s Plus has the largest screen, best camera and best battery life.
Both 6s phones have the pressure sensitive Force Touch screen.
The SE is the same size as the 5s but has the 6s's faster processor.
The plain 6 is a year behind the others.

Both the iPhone 6S Plus and the iPhone 6S look nigh-on identical to their immediate predecessors, which means that they also look very similar to one another - with one notable difference… Just like the last generation, the iPhone 6S has a 4.7-inch screen while the iPhone 6S Plus has a larger 5.5-inch one.

Buy a 6s, 6can bend, SE is small
