Google Inc will slash 20 percent of the workforce of Motorola Mobility in the Internet search giant's largest job cuts ever as it moves to make more smartphones and fewer simple mobiles.
The news sent Google's shares up nearly 3 percent but analysts said it was unclear if the cuts were enough to restore the fortunes of Motorola, whose last hit was the Razr flip-phone launched eight years ago.
"I think it's still going to be challenging to navigate the waters (of the handset business); how do you keep your partners happy and how you push your own smartphone devices at the same time," Morningstar Inc analyst Rick Summer said.
"This is the obvious step. The things that are harder are how do you drive profitability, how do you carve out a niche for Google devices, how to end up delivering solid returns on capital."
Google bought the money-losing cellphone maker for $12.5 billion last year - its largest acquisition ever - aiming to use Motorola Mobility's patents to fend off legal attacks on its Android mobile platform and expand beyond its software business.
By pairing Motorola's smartphone hardware business with its Android software, Google may have a better chance of mounting a direct challenge to Apple Inc's popular iPhone, technology market observers believe.
