Reason Why Your iPhone Battery is being destroyed

While going through some articles, I came across one from Business Insider that was saying your iPhone battery is dying because there are 2 types of bugs in your phone. If you have an iPhone and happen to updated your phone to the iOS10, its making your battery die much faster than normal. Another reason is that the iPhone 6s switches off although you have plenty of battery left. I myself, never had to deal with these problems with my phone, but now it makes sense as to why it is doing it to other peoples iPhone.
