I just recently purchased myself a shiny new Oasis 3 (thank you Amazon Prime day) and I also purchased new Paperwhites for my wife and son.
I've been using the Oasis 3 for just over a week now and the battery is really really bad! I tend to charge my Oasis every 2nd day with about 3 hours of reading a day (light on a mid setting for 50% of the reading time). WiFi is off. I also only have 3 books loaded.
I did a full reset of the device and the battery is still the same
The battery even seems to drain about 5-10% overnight... Doesn't make sense.
My wife and son haven't even charged their Paperwhites once yet over the past week.
Is the battery on the Oasis supposed to be this bad?
