Amazon And Barnes & Noble Fight Over Battery Life

Ever since Barnes & Noble came out with their new


Nook Touch, which can apparently hold one charge for two months (measured as 60 hours on half an hour a day with Wi-Fi off), the retailer has been participating in a oneupmanship with Amazon.

Amazon responded to the Nook news by introducing a 3G version of the ad-supported Kindle for $164 and changing its battery life description on the Kindle product page. The site reads: “A single charge lasts up to two months with wireless off based upon a half-hour of daily reading time. If you read for one hour a day, you will get battery life of up to one month.”

B&N retaliated, defending their self-proclaimed longest battery life claim. The retailer released a statement attributable to Jamie Iannone, President of Barnes & Noble Digital Products. He stated: “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.”

It seems the numbers keep changing.
