In the most unlikely circumstance, Wistron has vocally spilt the beans about the upcoming iPhone 7 Plus. The company's chief executive has recently told the press that Apple is finally putting the controversial wireless charging capability into the frame as well as an improved waterproofing technology.

Wistron's Robert Hwang on Wednesday revealed at the company's annual shareholder assembly that the iPhone 7s Plus is coming soon with the much-awaited wireless charging technology. In addition, the Cupertino firm has also been said to make a few alterations in its design to accommodate an improved water resistance smartphone.

In the words of Hwang, he says, "Assembly process for the previous generations of [iPhones] have not changed much, though new features like waterproof and wireless charging now require some different testing, and waterproof function will alter the assembly process a bit".

Speaking to the reporters, Hwang mentioned of new testing schemes that Apple will use for the next iPhone model. The iPhone 7s Plus is expected to be dropped in the fall alongside the iPhone 8 and iPhone 7s. Rumours suggest that the wireless charging technology will not only be available to the iPhone 7s Plus but to the iPhone 7s and iPhone 8 as well.

Apple Insider has a few details about the supposed wireless charging and improved water resistance. According to the publication, one way to accomplish wireless charging is by placing the device onto a pad or surface. The iPhone 7 has an IP67 water resistance rating so Apple could go beyond that with the upcoming iPhone releases.

The executive's revelation is an apparent violation of the non-disclosure agreement entered into by these companies. However, there have been no confirmation if Apple is taking a disciplinary action over the Wistron executive's move.

Following the failed attempts of some tech firms to produce wireless charging regardless of which device to use, analysts see it immature for Apple to deliver such an innovation on top of an existing one. Gizmodo reports, "But what's the harm in having both wired and wireless charging? There's not really a downside apart from the aforementioned extra bulk and cost".
