Ok I think the battery is not holding a charge as long as it should be... I thought the battery lasts 2 weeks without using the whispernet... Well it lasts only 4-5 days... I'm not suprised that the battery is losing it's charge, since Kathy's daughter had the K1 since Oct 25... So almost a year now... However tonight I noticed something very odd... See I charged the battery lastnight... Tonight when I used it, after a few minutes, a quick message popped up saying that the Battery Is Low nd the Kindle shutdown... Hmmm Strange indeed... So I put it on charge again... After 10 minutes the light turned off... Just as I thought since I charged it already... And then I had no more problems... I guess I'll start using that extra battery now! lol... And it looks like I'll have to buy another one though as a spare... But anyways has anyone else had this certain problem with the battery?
