Why does the battery become the biggest pain of the mobile phone?

Unexpectedly, the battery became the most photogenic word of the year for mobile phones.

On December 2, Apple released "information about the iPhone and accidental shutdown" on its official website(including the Chinese website), explaining the reason why iPhone 6s users have repeatedly reported that the iPhone has half or even 80 % of the power of the iPhone. It also stated that it will replace the batteries of the affected equipment for free.

Besides the iPhone 6s, which phones have fallen on the battery?

Apple officials found that in a handful of iPhone 6s devices produced between September and October 2015, a battery element was exposed to air in a controlled environment for too long before it was loaded into a battery package, causing the battery to consume power faster than normal, causing an accidental shutdown.

Another fruit fan and eating melon crowd did not expect that Apple also fell on the cell phone battery.

So the question is, what other phones have fallen on the battery besides the iPhone 6s?
