Your concern fails to take into account the fact that frequent shallow discharge/recharge cycles are much better for a Li Ion battery than less frequent deep ones. It seems reasonable to suppose that a typical usage pattern for the Oasis would involve it being returned to the cover relatively frequently, leading to shallower cycles and prolonging the life of the battery. There's also the possibility that the designers of the Oasis could have exploited the dual battery design of the Oasis in ways to further prolong the life of the battery. For example, having the recharging cover readily available could be seen as reducing the need to push the capacity of the device battery to its maximum. Reducing the peak charge level of a LiIon cell dramatically extends its lifetime (e.g. dropping the charge voltage from 4.2V per cell to 4.1 V per cell will typically double the lifetime). I clearly don't know if the designers have actually made such a choice, but there's no reason to assume they haven't. The claim that the Oasis battery will have a shorter lifetime than other Kindles is just conjecture - unless you have inside information about the design and typical usage patterns I'm not privy to, to present it as a fact is misleading.

Even if it was as low as 5 years, I strongly suspect I'd be itching for a new gadget by that time and would love to have a diminished battery capacity as an excuse! ![]() |

It is in any case true that this failure mode is greatly reduced by charging and discharging in small amounts rather than by doing deep discharges, and that's just the operating profile an Oasis battery sees! (At least, that's what it sees unless you're in the habit of not putting it in the charging cover when not in use, or unless you really do usually read in uninterrupted six-hour stretches). In practice, though, 'premium' overpriced product or not (even though I own one and love it, I freely admit its price is ridiculous), this is portable consumer electronics. By the time you notice significant battery degradation the thing will probably be overdue for replacement anyway and probably battered-looking too. If you think you'll need it for longer, get an extended warranty and replace the battery right before the end of it, though they'll only do that if the battery is at half capacity by that point and they'll probably do it by replacing the whole Kindle. |

All of these battery issues/concerns/outbursts/fears/exhortations/predictions/declarations/diatribes/[fill in your affiliation here] would be tucked safely away if Amazon treated the Kindle like cell-phones - regarding the battery. Just pop off the back and put in a new battery.
But it won't happen. In the meantime, enjoy your new ebook reader. And if not....why, just return it. ![]() ![]() ![]() ![]() ![]() ![]() |

I'm of the opinion that everyone should evaluate based on their own usage patterns (or planned usage patterns).
If I was going to use the Oasis because of it's ergonomic design, and based on my reading habits, I would be worried about battery life. I think I would go through a lot of charge cycles. I can appreciate the reader is designed to be put in the cover whenever you aren't using it, but why change my reading habits due to thier design decision? I also tend to pass the reader along to family members (or maybe even sell it), and I'm not sure I would be comfortable doing this with such a limited battery size (1/5 of a typical ereader battery). |

Neither here nor there, but...
I went to use my ~10 year old DSLR the other day (it has lion batteries). I did a full charge before I used it, and I was only able to take about 20 shots before the battery died. My spare battery didn't fare much better. |

I didn't need to change my habits at all: it was certainly a smaller change than, well, reading one-handed was. (I was forced away from reading one-handed about ten years ago by advancing RSI: the ability to go back to that again was a big part of why I got the Oasis. If you always used to read paper books two-handed the Oasis is probably not useful for you.) |

The original poster should note that JSWolf has completely changed the subject so that he could badmouth the Kindle some more. Something he's been doing since before there was a Kindle--when all we knew about it was the FCC filing. You should disregard all the blather about battery life as an attempt to keep you from buying an Oasis. If you're not sure it warrants the expenditure of the money, go to a store that sells them and look, or buy from Amazon and return it if you don't like it.

Anyway that was a bit off topic. I think the OP should buy the kindle that fits his needs and budget. If it doesn't work for him Amazon has a 30 return policy. |

Quite. It's not about the battery life, JSWolf notwithstanding -- that's "effectively forever, get surprised when it runs out of power" just like all e-ink Kindle models. It's all about the ergonomics. If you want one-handed operation and can afford it, go for it! In my case it cost about what I spend on books in two or three months, my existing PW1 was visibly ageing, I liked the look of the ergonomics a great deal, and I had an old birthday present of £100 towards a new Kindle to spend anyway, so I leapt at it: I always bought a cover to go with new Kindles so it wasn't even particularly overpriced.
Others might well have different priorities. This doesn't mean they're wrong (though of course it does of course mean they are *evil* and probably planning to destroy the universe in the next book). |

Thank you for your opinions (divergent as they were).
My key concerns are ergonomics (broadly defined), including weight and the ease of page turning and using the device to read without too much worry that the device will surprise me with a loss of power when I am at a key point in the plot, or just otherwise desperate for a good read. Ideally, I think you should be able to forget you are holding the device at all as you become completely immersed in what you are reading. Your ability to do this will depend on the quality of the book and the device. Everything that distracts from actually reading the text takes away from the experience. I spend a lot on books and an ereader that improves the reading experience is worth the money. And I deserve the occasional splurge. So the kindle oasis will be the next device. Just a question of when. The cover is only available in black right now in Canada and I will probably continue with my paperwhite until they add the walnut brown as a choice. (Black is fashionable but it becomes difficult to see when you toss into your carry-bag. By the way, who is holding their breath to see the booker longlist on Wednesday? I think there are enough books this year for them to redeem themselves from the follies of the last few years. ![]() Last edited by seanyyz; 07-25-2016 at 03:09 PM.
