Nothing makes the present-day generation happier than buying a new phone. But shopping does not end here you also have to buy a new phone case. Each and every manufacturer try hard to keep their handsets unique. Thus, it is almost impossible that a case designed for one model can fit another perfectly. Even if the phone is of the same brand however there are some exceptions to this. For example, are the iPhone 6s and 6 the same size. the iPhone 6 and iPhone 6 S can adjust well in each other’s case.
There are companies, like Speck, who have announced that their iPhone 6 cases will fit the new iPhones too.
Yet I suggest you personally have a look at the new iPhones in order to make sure that your old Phone case fits well. But we can expect the statement true by considering the looks of both models as they look similar.
Both models are the same in height and width except for the difference of some fraction of millimeters. The iPhone 6S is slightly bigger than it preceded. And the 6s weighs more, too.
If you have a flexible silicone case or a leather case there are chances that you can save money on that as their flexibility allows them to stretch a little bit to accommodate iPhone 6S.
iPhone 6s Plus
The iPhone 6S Plus is bigger than its predecessor model in all aspects it is taller, wider, deeper, and weighs more too. But same as in the preceding case it is also a matter of some millimeters.
So, here the answer is yes. There is a great chance that all iPhone 6 models either it is an iPhone 6, iPhone 6S, or iPhone 6 Plus they all can fit in the same case if your mobile case is made of silicone or any other stretchable material.
