Yes it could be. Even if the problem didn't occur with my reader i've seen enough posts on this topic. Nobody knows why a SD-Card should drain the battery when the reader is in sleep-mode. If the problem still exist, i would backup the contents and reformat the SD-Card - even if there is no lucid explanation why this could help.
