Announced today, Kindle now has an improved battery life when the wireless connection is turned on. Compared to its previous 4-hour battery life, the Kindle can now run up to seven days with the wireless activated. Battery life with the wireless connection turned off still remains, which is about two weeks.
“Battery power management for portable wireless devices is a complex technical area, and the battery life improvement announced today is the result of a six-month firmware improvement and testing program,” according to the press release.
In addition to the battery boost, Amazon has also added native PDF support to the Kindle. The company says users can now “read professional and personal documents in their original PDF format without conversion.” In order to read these PDF files, you can either email the files to your Kindle email address or transfer them via the USB connection. You can also easily convert your PDF files to the Kindle format by typing the word “Convert” in the subject of your email.
According to a press release, all new Kindles will be shipped with the battery boost and native PDF support. Users who already bought the Kindles before will be receiving the new enhancements via a firmware upgrade which will automatically be sent to them when the wireless connection is turned on.
