According to Taiwan media reports, Apple (hereinafter referred to as "Apple") will release the iPhone 7 in the second half of next year with new composite materials, which can be waterproof and can hide ugly antenna strips. Apple may want to integrate the antenna into the shell, making it part of the shell.

Compared with previous models, the waterproof performance of Apple iPhone 6s/6sPlus has been greatly improved due to the addition of gaskets and silicone seals at many places. However, in Apple's view, the new iPhone 7 still needs to be completely redesigned in terms of waterproof performance, including how to solve the waterproof problems of ports, switches and buttons.

In June this year, it was also reported that Apple had applied for a new patent, which described a new composite metal material. The appearance and touch of this material is almost the same as that of anodized aluminum, but it has the ability of signal penetration. This means that the iPhone can be made of all metal materials in the future, thus eliminating the current plastic antenna strip, but the phone signal will not be weakened.
