They can probably be replaced if the cases can be opened. There is a trend nowadays to make a case out of two parts, and then glue the parts shut so no screws are necessary. It can make a device a milimeter or two thinner. Maybe they did that with the Oasis, maybe not. I don't know.

I think the best thing about the Oasis is NO ONE IS FORCING ANYONE TO BUY IT! It's totally optional! Not mandatory! If you don't like it, you don't have to buy it! That's why Amazon offers 3 other Kindles! You don't even have to buy a Kindle! Hate Amazon? Buy a Kobo or other brand!

Choice is a wonderful thing.

Now, back to reading on my Oasis ...

P.S. Apologies to those who respect that the Oasis has its merits, even if it's not for you. This rant and show of temper is not directed at you.

The problem that concerns me is that reading the Oasis without it's cover will use up that little battery almost 6 times faster than reading on a Paperwhite, leaving a very expensive paperweight.

If the cover is on while reading there might be a better situation if the device runs off the cover battery and not the internal battery. I think I read somewhere that that's the way it works but I don't recall where I read it and I can't find it again so I'm just not sure.

Anyway if that is the way it works, if reading it in the cover uses only the cover's battery as long as the internal battery is charged, that means it will probably be a long lived device as long as you leave the cover on.

On the other hand if it always runs off the internal battery and the cover just keeps that charged, the Oasis is doomed to an early death. Just as it would be if you read it out of the cover all the time.

I have no way of knowing for sure which of these is the true situation and I find it difficult to believe that Amazon didn't think of this, but I guess that's possible. They don't miss much but things happen.

Anyway, I'm not buying an Oasis until I know more about this and if I already had one I'd keep it in the cover to try to protect it as much as possible. This is a scary situation.

I did send some feedback to Amazon and hopefully they'll let me or everyone know something about this. It looks to me like a pretty nice device but right now I'm afraid of it and I think it's something Amazon needs to explain.

Let us know what they say Barry. I think a lot of people would as well. Thanks !

I think most of this is Amazon's fault. I buy Kindles (as well as other brands of ereaders) and I'm already very attached to the Oasis but I think Amazon is arrogant and stubborn and it annoys me enough that I almost hate buying Kindles.

I'm annoyed that after all these years and all these generations and all the improvement in screen resolution there are still only eight font sizes and few other ways to customize the look of the pages in books.

I'm annoyed that their quality control is so lacking that hoping for a good screen is like buying a lottery ticket.

I'm annoyed, and also worried, that there is so little information provided about the split battery system on the Oasis. Neither the product page nor the user guide has one word about how the split battery works -- the conditions under which the cover will recharge the Oasis, and the amount of reading time to expect from a fully charged onboard battery (not even the weeks-at-half-hour-a-day ad-speak).

Saying that it works as it's designed to work doesn't seem very sensible to me; we don't yet know either how it was designed to work or how it does work.

Well, I'm glad to get all that off my chest.

Why not chime in with Useful Information about the Oasis?

I Noticed No One has done a Review on MR that Owns an Oasis. Most every Fire Tablet Phone & Several of the e-ink reader have Very informative Review on here BUT Not One person with an Oasis has done a review on it. I was even told by one person that did a Review BEFORE they even had the Oasis he was going to come back when he got his & do a Review. Yes he does have it But the only review hes done was How to unbox the thing its been weeks!

I get your point, Barry. Personally I am not that concerned, though. You say a lithium-ion battery typically will last between 500 and 1000 charges. Let's assume the built-in battery lasts only 500 charges.

I read about 6-7 hours with the built-in battery of the Oasis before I have to recharge it. So 500 charges with a minimum of 6 hours reading time give me about 3000 hours of reading.

Simple math tells me, that I could read 1 hour a day for the next 8.22 years.

Or 2 hours a day for the next 4.11 years. If the battery lasts 1000 charges, you can double the values.

That is a lot of reading time! I'm pretty sure I will own the next generation Kindle before the battery of the Oasis will be running out.

It would be worth everyone's time to go take a look at Battery University to learn about batteries rather than guess.

Did the K1 have a 250mAH battery? No, it had a ~1350 mAh battery. Your experience with the K1 is irrelevant to the discussion on the 250mAh battery on the Oasis main device.

Do not dismiss that which you are ignorant about. If you cannot contribute anything meaningful, stay out and let those who know what they're talking about talk.

But what concerns? That it is a device designed to do what it does? What concern is there with that? That wild speculation about a battery? Is that a concern or lack of understanding?

I think those of us that own the device have posted useful information. Just seems that some don't want to hear it.

I don't do reviews, period. Rarely do I review things I purchase. Just not my thing. I think there are lots of info bits, better than reviews, in all the Oasis threads by those that own it.

I'm a little puzzled by your remarks, Katie. Many people who've bought an Oasis have posted their opinions of it.

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.

Perhaps you like the device, and you'd like to replace the battery when it dies, rather than buy a new reader. There's a market in third-party replacement batteries for all Kindles. Some models are easy to change the battery, others (where everything is glued together) less so.

Perhaps because people feel, as I do, that MR is a very hostile environment for those wanting to report positive reviews of their Oasis. Lots of people here wanting to disagree with you, without themselves owning the device. Just not worth the time and trouble.
