Google is betting consumers will pay slightly more for a sleeker, more powerful version of its Nexus 7 tablet as the Internet company escalates its rivalry with Apple and Amazon.com in technology's key battleground - the mobile computing market.
The fancier devices unveiled Wednesday in San Francisco will go on sale in the U.S next Tuesday in Google's online store and numerous retailers with brick-and-mortar stores.
Among other things, the souped-up line of Nexus tablets will boast a higher-definition 7-inch display screen and a processor that promises to be nearly as twice as fast. Dual stereo speakers have been added for richer sound, and the device's battery duration has been extended to 10 hours for Web browsing, an increase of about an hour.
The extra firepower added to the second generation of the tablets will come with a higher price. A model with 16 gigabytes of storage will sell for $229, a $30 per increase from the current Nexus 7 released a year ago. That's still 30 percent below the $329 that Apple Inc. charges for its iPad Mini. A comparable Kindle Fire HD tablet from Amazon.com Inc. currently sells for $199.
A 32-gigabyte version of the Nexus 7 will sell for $269, a $20 price increase.
The price hike for the Nexus 7 comes at a time when more people have been showing a preference for less expensive tablets. Google helped propel the trend with last year's introduction of the Nexus line, contributing to pressure for Apple to come out with the iPad Mini as an alternative to its top-selling tablets with a 10-inch screen.
Google is confident the Nexus 7 will still look like a great value once consumers see how much more powerful the new models are, said Sundar Pichai, an executive who oversees the company's Android and Chrome software.
The iPad Mini has driven down the average selling price of Apple's tablets, hurting the Cupertino, Calif., company's profit margins.
Even at a lower price, the Nexus tablets haven't been as popular as the iPad. Pichai said the Nexus products account for about 10 percent, or 7 million, of the roughly 70 million tablets now running Android software.
In the first half of this year alone, Apple sold 34 million iPads, including full-size models.
Amazon.com doesn't disclose its sales of Kindle Fires, which run on a modified version of Android. The research firm IDC estimates about 1.8 million Kindle Fires were sold during the first three months of this year.
The Nexus 7 will be the first device to get the 4.3 version of its Android software. It's a relatively minor upgrade from the "Jelly Bean" flavor of Android. Google still hasn't said when it will release a more comprehensive Android overhaul, currently known as "Key Lime Pie."
As with the original line of Nexus 7s, the new devices are being made by AsusTek Computer Inc., working from Google's design.
Google is still tinkering with a new line of Nexus tablets with 10-inch display screens. The Mountain View, Calif., company also hasn't updated its Nexus 4 phones, though it worked with phone makers to release variants of Samsung's Galaxy S4 and HTC's One this summer. The variants run a pure version of Android, without the customizations added by the phone makers.
