joutei: I for one find it sad that a network carrier should get blamed for the manufacturers fault.
Anyway, realistically speaking smartphones mostly give you around 8 - 10 hours.
If you expect more for a $1000 phone then that is something you should bring up with apple.
Even the new Nokia Lumia 920 baterry life isnt impressive.
From what I understand, the 'network carrier' is the 'retailer', and under NZ law they must sort out problems with the product. It's not sad at all, it is the law. They can of course choose not to be a retailer and not sell phones to consumers.
