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.
