Barnes & Noble clarifies battery life on new Nook, calls out Kindle

Wondering which electronic reader reigns supreme when it comes to extreme battery life? If you ask Amazon, it's the Kindle, but Barnes & Noble begs to differ -- and it has some numbers to back that up. Earlier today we received a statement from the company explaining just how thrifty the new Nook is when it comes to sipping from cells. With WiFi disabled on both devices, B&N says it managed 150 hours on the new Nook when turning a page every minute. The current-gen Kindle, meanwhile, petered out after 56. That's almost three times as long and maybe, just maybe, enough to finally get you through Anna Karenina on one charge -- or at least through the Cliffs Notes version. More details on the testing overview below, which we promise can be rather more rapidly ingested.

With up to two months on a single charge, the All-New NOOK has the longest-battery life in the industry and superior battery performance to Kindle 3. In our side-by-side tests, under the exact same conditions, continuous use of the device resulted in more than two times Kindle's battery life. While reading at one page a minute, the All-New NOOK battery lasts for 150 hours where the Kindle battery, using the same page-turn rate, lasts for only 56 hours (both with Wi-Fi off). We've also done a continuous page turn test and at one page turn per second, the All-New NOOK offers more than 25,000 continuous page turns on a single charge.

Barnes & Noble announces new touch-enabled Nook for $139

Not to be outdone by Kobo which just unleashed it's latest E Ink reader yesterday the folks at Barnes & Noble are back with the latest update to their line of Nook devices. The "all new" Nook is touch enabled and lasts up to two months on a single charge. The Pearl E Ink screen boasts "80-percent less flashing" during page turns, something that many fans of the devices have resigned themselves to having their eyes assaulted by. And B&N is quite proud of its streamlined interface which it brags has 37 less buttons than the Kindle 3. Around the back is a soft-touch rubber surface that should feel great in the hand while reading, though, we'll have to wait to manhandle one ourselves to be sure.

The new Nook has a redesigned home screen with your current reading list and suggested titles and adds a few features like FastPage Zoom forward, which lets you jump to any page in a title, and (finally) displays the number of pages left to go. Inside is a microSD slot and a WiFi radio, but sadly no 3G. You'll also be able to share quotes, lend books, and update your status on social networks using Nook Friends, which debuted last year with the Nook Color.

You can pre-order online and in stores now and the updated Nook should start shipping to customers June 10. You'll also be able to pick one up at BestBuy, Walmart, Books-A-Million, and Staples for $139 at the same time.
