Truth is,they’re not that different.
In fact, almost every major element of the iPhone 6S and 6S Plus is the same.
But there are a few differences some subtle, some very obvious that set the two models apart.

Screen Size & Resolution
Apple Inc. You should know pretty quickly whether the 6S Plus will be too big for your pockets and hands.
And they are, except for one crucial difference: The 6S Plus offers optical image stabilization.
Image stabilization reduces that shaking and delivers better photos.

The 6S stabilizes images using software.
That’s good but not as good as image stabilization delivered by hardware built into the camera itself.

The size difference is driven almost entirely by the screen sizes of the two models.
Those differences also affect the weight of the phones.
