All you Need is an iPhone or iPad capable of running Siri (iPhone 4s or iPad 3 and newer), Internet or Cellular Connection, and an *external battery case.
This is a way for Siri to compete with the always on “Ok Google” android feature.
Your iPhone does not need to be jailbroken!
Such a great feature of the new OS that Apple didn’t mention.
If you have any questions, comment below!
Great work around.
Id love to yell HEY SIRI in class to fuck with anyone using this "hack"
What a twat… an external battery is still a power source
