Poor battery life

I have been very disappointed in the supposedly upgraded kindle. I bought it to replace my seven year old paper white which finally gave up the ghost. While lightweight, the formatting is not particularly user friendly. And while the touch screen is ok, it frequently skips pages or jumps sporadically ahead. My biggest concern however is the battery life. I find that I need to charge this device daily while my old paper white could last a week on one charge. Perhaps I received a defective device because this is certainly not an improvement.
