Kindles have background processes which do drain the battery badly. To support their search feature, they will index all of your books that are downloaded onto the kindle. They will also regularly poll the network to download new books you've purchased. And then there's bluetooth (on the Kindle Oasis). I've had an "off" kindle drain itself dry in a day from these.

  That's your right, but it's a pretty useless comment. New kindle oasis, downloaded as much of my library as I could. Once downloaded, I pulled it off power (not realizing there was an indexing process). Battery goes dry, internet searches reveal the indexing process occurs with a download. Even now the Oasis can't stand up to a long-ish book's worth of reading if the network's on.

> I've had an "off" kindle drain itself dry in a day from these. I find that hard to believe. I've left my in non-airplane mode and maybe after a week it drops 40%. Since I always leave it in Airplane Mode I'm probably seeing different behavior than OP. Plus it is an older kindle, not a fancy new one. But still: screw active Wi-Fi.

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).
