Wondering Why The Headphone Jack Missing In The iPhone 7? Here's Why

With every new iPhone release, it is now a tradition for iFixit, the device repairing site to break the device apart and look what has changed inside. Through the teardown process, they found out just what replaced the headphone jack exactly.

So as expected, iFixit performed a complete teardown of the iPhone 7 and iPhone 7 Plus to dole out information about internal parts that Apple preferred to leave out in its keynote speech during the iPhone 7 launch event.

iFixit says the process of tearing down the iPhone 7 Plus is quite similar to the previous models. It found that the classic pentahole screws are still there along with two familiar screws holding each side of the lightning connector.

Because the iPhone 7 Plus is now water resistant, the device opens to the side once the display is removed.

Coming to the headphone jack, the geeks at iFixit found that the newly introduced Taptic Engine takes up most of the space reserved for the 3.5mm headphone jack. However, interestingly there is now a plastic bumper where the headphone jack used to be.

While the Taptic Engine that powers the home button in the iPhone 7 Plus is the reason for the headphone jack going kaput, iFixit notes that water proofing is also one of the major reasons for ditching it.

Apart from this, iFixit also found out the exact amount of juice the new iPhone batteries have. While the iPhone 6 Plus ran on a 2750mAh battery, the new iPhone 7 Plus features a 2915mAh battery. During the keynote speech, Apple only revealed the new iPhone 7 Plus will give an hour of battery more than its predecessor. With the exact figure revealed, it seems it is indeed the battery that has become larger along with OS-level optimizations.

The dual camera setup was also examined by the team at iFixit. It noted that the camera has "dual lenses, dual sensors and two little connectors."

There are two 12-megapixel cameras, one with a wide-angle lens along with optical image stabilization similar to the iPhone 7 and another, a telephoto lens for optical zoom.

There are also two sensors that Apple claims is 60 per cent faster and 30 per cent energy efficient than the predecessors.

The cameras are built into a chassis to enable waterproofing and dust protection. This chassis is the reason behind the ugly camera bump in the iPhone 7 Plus.

The website still hasn't started the teardown of the 4.7-inch iPhone 7. As for the new Apple Watch Series 2, the teardown process has just started which iFixit notes is now much easier thanks to the new ZIF connectors.
