Inside an iPhone Battery Factory - in China

[Pete_UZ]

Even though iPhone battery is no more a secret part for most end users, since we can easily buy third part one and replace it by ourselves, an on-site visit of iPhone battery factory is still new to most people.
This video is a great intro for those have curiosity on this topic  
It should be noted that besides the factory mentioned, of course there are other manufactures on this job and it is easy to google them out.
