Respuesta a "Why does my Kindle DX battery run down within 3 days?"the dx should keep its charge 4 - 6 weeks. if it drains in 2 or 3 days with a new battery then the display was most probably replaced with an oem version from Ebay. You can open it up and search for traces like broken lids on flatcable clamps etc. Often it shows somewhere. Manufacturers can sell rejected production units online.
