Why iPhone 7 Can Blast
Oh-oh, 7 seems to be an unlucky digit for smartphones! Following the news about fire hazardous Samsung Galaxy Note 7, came the bit about the iPhone 7, that blasted on its way to an Apple fan from Texas. Reddit user kroopthesnoop posted the pictures of an unlucky device to support his short but sad story.
A co-worker of his pre-ordered the iPhone and was so excited to have his hands on the new smartphone that called all the office to have a look at the purchase. But when opened, the package revealed the smartphone scorched remnants.
Apple’s representative already reached out to the disappointed owner and promised to replace the iPhone free of charge and expedite it. But the question remains, whether iPhones 7 is still dangerous for users? With imagination running wild, can the smartphone blast during a talk when pressed against one’s ear? Nightmare scenario.
But let’s be brave and try to find out why smartphones can blast and what circumstances can it happen under. The only explosive matter of the modern gadget is the battery. The LI-Ion battery with long life and numerous charge cycles. Li stands for Lithium – the alkaline metal. Wiki says (and we quote): “Lithium is flammable, and it is potentially explosive when exposed to air and especially to water, though less so than the other alkali metals.”
Can you see the point? The content of the battery is dangerous only when exposed to air. And this can’t happen unless the battery casing is damaged. Now we come to the issue what can cause this and why. Battery casing can be damaged mechanically or chemically, other words, it can be pierced, broken or melted.
Here’s an enlightening video about what happens to the Li-Ion battery pierced by a kitchen knife.
Obviously, in real life no one would mutilate the smartphone battery this way. But punctures and rips can be caused by careless treatment. And coming back to the Texas case, just this could happen to the iPhone 7 package on its way. A careless shove and here we are: the battery damaged and burnt, the smartphone ruined. Of course, you can’t damage the battery casing just dropping your iPhone 7, it must take the bunch of very unhappy circumstances to take place.
The melting scenario is much more probable. Just like this happens to the bad luck Samsung Galaxy Note 7. Users reported, the smartphone turned very hot prior to igniting. And this happened when the gadget was being charged, other words, when the battery was most likely to be overheated.
As we can see now, while for Galaxy Note 7 the fault lies with poor engineering, iPhone 7 blast accident is just a combination of highly improbable factors. Careless packaging and treatment someway between the store and the purchaser.
So, you must not be afraid of your iPhones 7, provided, you won’t pierce it with sharp objects.
