iPhone 7/Plus Launches, Teardowns And Stress Tests Ensue

Today is the launch day of the iPhone 7 & 7 Plus. Some people prepare their new device for day to day use, while others go about finding out what makes these new devices tick. First off, iFixIt is back with a teardown to reveal what’s in place of the the headphone jack. Apple used the area to put in the taptic engine for the redesigned home button. There’s also room for a barometric vent to help gauge your altitude with varying air pressure, especially because the rest of the iPhone is sealed for water resistance.
The iPhone 7 Plus teardown in particular shows new 3GB of RAM, a bump up from 2GB on the 6S Plus. The battery has been increased from 2,750 man to 2,900. The iPhone 7 on the other hand has the same 2GB of RAM as the 6S. The battery of the iPhone 7 is rated at 1,960 mAh, which is a nice bump from the 1,715 mAh battery of the 6S, which was actually down from the 1,810 mAh battery of the 6. The A10 processor of the iPhone 7/Plus is made by TSMC, and is one of the thinnest system on a chip that Chipworks has seen. The die size is roughly 125 square millimeters for 3.3 billion transistors. The A10 chip takes up the same space as the A9 chip, but vastly improves the number of transistors and performance.

Beyond the teardowns, there are also users posting videos of stress testing the iPhone 7. The iPhone 7 is water resistant, and of course people have tested that. The first video below shows the iPhone in a glass of water still able to receive notifications, calls, and texts. Later in the video, the iPhone is then tested in soda and even hot coffee, and the iPhone 7 continues to perform normally without any distortions. Another user took their iPhone 7 to the beach to test the device lasting 20 seconds submerged in the ocean. The outdoor salt waterproof test came up just as good for the iPhone 7. Finally, iFixIt has a live video of an iPhone 7 in a fish tank with a timer running. As of publishing, the iPhone 7 has lasted five hours, and is still running, which is much longer than the 30 minutes of submersion that Apple suggests.

The video below tests the iPhone 7’s ability to withstand scratching and bending. The iPhone 7 glass front and matte black back hold up well to everyday items like keys and coins. The device can also handle 10 seconds of direct flame from a lighter before the pixels go black and overheat, but will return to form over time. The bend test also showed the iPhone 7’s aluminum chassis doesn’t bend like the iPhone 6, and is a substantial improvement.

Personally, I thank others for tearing apart, scratching, burning, and submerging their new iPhones so I don’t have to.
