Kindle owners rejoice: Amazon announced an upgrade and an add-on that should please current owners of the device and tempt a few more consumers into the fold.
Kindle engineers have been hard at work on a firmware upgrade that will increase the life of the device when wireless is turned on. Instead of lasting four days, Kindle will now last 7 — an 85% increase. Battery life with wireless off remains around 2 weeks.
Amazon is also adding a native PDF viewer. Now Kindle owners don’t need to convert PDFs to Kindle files in order to read them on the device. This works for both files loaded via the USB cable from the D5318 or those emailed to @Kindle.com addresses.
These updates will come via an automatic Whispernet update for current Kindle owners.Inspiron 6000 battery，Inspiron 9300 battery，Inspiron 9400 battery.
