Did you miss a "resistance" test for the iPhone 7? If so, then in the video clip below you can see an Apple smartphone frozen in toothpaste. The terminal is completely covered with target paste and left overnight in the freezer to adjust to the substance that surrounds it.
Although you might think that toothpaste could at least affect the charging of the iPhone 7 after a night in the freezer, well, the video clip below shows us the opposite. You can notice that in reality the terminal not only works without problems, but also charges as soon as the cable is inserted into the Lightning port.
