But many people wonder why their Kindle's battery depletes in a period much shorter than that. I used to too, but not anymore.
Here's everything explained.
The new, touchscreen Nook recently came out. Barnes & Noble advertises it's new e-reader to have a battery that lasts upto 2 months with wireless off. Amazon felt that B&N calculated the battery using an equation that assumed half-hour reading a day, with wireless off the whole time.
Amazon simply updated its own numbers on the Kindle's promotional page. They now say that the Kindle battery also lasts upto two months, just in the same way as the Nook.
"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. Keep wireless always on and it lasts for up to 10 days. Battery life will vary based on wireless usage, such as shopping the Kindle Store, Web browsing, and downloading content. In low-coverage areas or in EDGE/GPRS-only coverage, wireless usage will consume battery power more quickly."This explains everything. The Kindle's battery used to last upto a month with wireless turned off if you read an hour a day. If you cut down by half an hour a day, you can make it last for two months. But if you keep wireless on the entire time, you need to charge after 10 days.
This just makes sense. If you feel that your battery lasts for less than advertised, think about all the extra time that you read, browse the web, or shop in the Kindle Store.

However, whether the Kindle's battery is on par or superior to the Nook's or not is still an issue that is not yet clear enough as of this writing. Jamie Iannone of Barnes & Noble claims that in side-by-side tests, the Nook's battery was longer-lasting than that of Kindle.
