Is Larry Page Lying to Us?

The leak says the Moto X has a 1500 mah battery which is kind of pathetic.

Yesterday, Page said Moto's upcoming device would have great battery life.

Hopefully Page isn't lying to us, right?

Is it possible for both of them to be right?

Or is the tipster just wrong considering other leaked images actually measured the screen at 4.7" not 4.5"?
