The selling point of the device is that it can be used separately from the case.
A single charge on the device battery lasts 6-7 hours because it's a puny 250mAh battery.
Batteries have limited charging cycles.
A smaller battery will use up those limited charging cycles much faster than a bigger battery and lose it's staying power on a charge much faster, and dies sooner too
Charging cycles are charging cycles, and it makes no difference if the puny battery is being charged from a power outlet or USB or the case - as far as it's lifecycle goes - they're all equivalent. Just because you use the case to recharge, as opposed to USB, it makes absolutely no difference to it's inexorable march towards death (do you finally understand why it makes such a huge difference when a battery is 250 mAH as opposed to 1350??)
What you're going to have is an Oasis where the case battery will chug along merrily for long, but when your device battery itself stops holding a long enough (or any at all) charge, it completely takes away the option of using the device on it's own (which was a major selling point).

It's certainly a fact but is it a relevant one? Let's introduce another fact. Batteries DO NOT just die. Their ability to hold a full charge slowly diminishes.
Let's use 500 charge cycles although it is likely to be greatly in excess of that.
Relevant fact A. 6 hours. 500 charge cycles. 3,000 hours, at 30 mins per day, 6,000 days. It's over16 YEARS!!!
Relevant fact B. If you read for 6 hours a day (greatly exceeding the design parameters and claims (non-Amazon) for the device) then you get 500 days. Should the battery ONLY give you 500 charge cycles, the battery will begin to dimish slowly over another 500 charge cycles.
So for A, let's say you'll get 10,000 days and then the battery ceases to hold a meningful charge. Well, who cares. It's a very long time.
So for B, you've still had exactly the same reading time out of the battery if you call its life two years. Therefore, if you read 6 hours a day every day then maybe you may, and I emphasise may, wish to consider a different device if you realistically consider your reading timeis that significant.
So there are facts. When these facts are applied to the Real World(tm) are they relevant. Application of relevancy will give you a rational answer and prevent pontless outrage.
For the "normal" reader the screen battery life is totaly irrelevant as a very simple calculation tells you it is more than adequate and will likely outlive the device. For the heavy reader then the application of quiet plain common sense should prevail and not wild assertions.
Fact: Caffeine is a diuretic.
Irrelevant apple tree logic assertion: If you drink a cup of coffee it will dehydrate you.
