The lines on the back of the iPhones are a topic of discussion for many of those who own the Apple handset. And these conversations are mostly polarizing to the point that some absolutely hate the stripes, while some adore their impact on the design of the device.
But very few actually have a clear idea about why they are present on the iPhone. The 6 and 6 Plus models which were introduced by Apple last year were the first two offerings to come with these lines on their backs, and the new 6S and 6S Plus variants have carried forward the legacy.
These lines are white in color on the gold and rose gold iPhone models, and gray in color on the silver and space gray versions. They are contrasted by an aluminum body unlike the devices from the previous generations which used ceramic and glass and had no space for such lines.
Though we’re not sure about the exact reason behind the presence of these stripes, it can be concluded that they have something to do with the iPhone’s antenna or signal. Jeff Snyder from iFixit has told Business Insider that these lines may be present on the devices for providing a clean escape route for the signal out of the body.
The iPhone 5 and 5s have glass sections on their backs for serving this purpose, whereas the 4 and 4S models had glass backs. Rumor has it that the next-gen iPhones will be built with a composite material which will enable radio signals to escape without the need for such lines.
For now, those who hate the stripes on their iPhones will need to make do with them, and those who love them must enjoy them while they last.
