Motorola boss: I would love a battery tech breakthrough

Motorola's president has said that he would love there to be a battery tech breakthrough, but believes it will be a long time before his industry can offer a phone that lasts for a week or longer.

Rick Osterloh was speaking to the BBC to mark the launch of the Lenovo-owned firm's latest handsets.

They include two new Moto X models, which are marketed as being the "the world's fastest charging smartphones".

In the clip above, Mr Osterloh tells the BBC's Leo Kelion why he still hopes for an "unforeseen" leap forward.
