Assuming good faith on their part, it's a little more interesting to ask why their experience is so different from yours. It might be something mundane (different models, battery degradation, ambient temperature throwing off the voltage sensors on a partially degraded battery), or it could point to something like careless programming. E.g., I've had phones with 2day battery life in normal use which would fully discharge in 1-2hrs in the presence of weak network connections because of aggressive scanning and reconnecting (and I'd imagine the storage location for an "off" kindle wouldn't have great connectivity).
