As you can see there are not expected major changes in either the design or functionality of the new iPhone. It is rather a disappointing upgrade from Apple.

So I will say it does not make any sense in upgrading your current iPhone 6s Plus to the iPhone 7 Plus unless you have lots of extra money to throw away.
