Aug 13 (Reuters) - 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 as much as 2 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 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 loss-making cellphone maker for $12.5

billion last year, aiming to use Motorola Mobility's patents to

fend off legal attacks on its Android mobile platform and expand

beyond its software business.

Motorola's mobile devices unit has lost money in 14 of the

last 16 quarters. In the second quarter, Motorola reported an

operating loss of $233 million on revenue of $1.25 billion.

While many questions remained over whether Motorola's

strategy, Morgan Stanley upgraded Google to "overweight" after

the cuts.

"We believe that Google is planning to reduce Motorola

Mobility's smartphone portfolio to a few reference Android

devices, and perhaps a couple of tablet devices," analysts at

the brokerage said.

Google had evaded questions about its plans for Motorola

Mobility when it reported quarterly results last month, saying

it had yet to complete its homework on the various businesses.

Recent media reports have suggested that Google is shopping

Motorola Mobility's television set-top box business which is not

the best fit with Google's high-profit-margin Internet business.

WHAT SIZE FITS?

Morningstar's Summer said he does not expect mass layoffs at

Motorola, but said things might change as Google reviews all of

the cellphone maker's units and tries to sell the TV unit.

Others were similarly unclear about the right size for

Motorola, which will close nearly a third of its offices.

"They are still learning what makes it a leaner meaner

machine. I think as we move into the new year, there maybe more

right-sizing," said Susquehanna Financial Group analyst Herman

Leung.

Google said in a regulatory filing it expects to take a

severance-related charge of up to $275 million mostly in the

third quarter, but with some possibly trailing through to the

end of the year. It warned there could be some other significant

charges yet to be calculated.

Google shares were trading up 2.2 percent at $656.30 in

early afternoon trade on the Nasdaq. They touched a high of $655

earlier.

One-third of the jobs lost will be in the United States, but

the company has not specified where or what facilities would be

affected.

Earlier the New York Times reported Google's plan and said

it was looking to shrink operations in Asia and India, by not

just exiting unprofitable markets, but also stopping making

low-end devices and focusing on a few cellphones instead of

dozens.

Motorola Mobility, which has 94 offices throughout the

world, will center research and development in Chicago,

Sunnyvale, California and Beijing.

In addition to the planned cuts, Google has downsized

Motorola Mobility's management, letting go 40 percent of its

vice presidents, but has also hired new senior executives, the

New York Times said.
