K3 battery life stinks... what?

Does the Kindle use a lithium-ion battery? If so, does the following advice from the "Battery University" apply:

Do charge the battery often. The battery lasts longer with partial rather than full discharges.

Likewise this:

Avoid full cycle because of wear. 80% depth-of-discharge recommended. Re- charge more often. Avoid full discharge.

Li-Polymer.

>> ... cadex.com for portable power info ...

A very good source. Their book, "Batteries in a Portable World," is mandatory reading for anyone truly interested in portable power.

I'll be keeping hundreds if not thousands of books on my Kindle. I plan to use it as a reference tool as well as a reader. I also look forward to the pleasure of being able to re-read a favorite book, or parts thereof, on the spur of the moment, wherever I happen to be. I can carry two p-books in my backpack; I can't carry two hundred or two thousand.

Can you disable this indexing or make it only relevant to the title of the book?


i don't really want to search the text in the books.i just want the titles to be indexed/found so i can read it.

just as a matter of interest could i index the books on my pc instead and load the index file into the kindle instead so the kindle does not need todo it all??

No, you can't disable it.

Actually, Battery University is a Cadex-sponsored website. The article on Charging lithium-ion batteries is by Isidor Buchmann, founder and CEO of Cadex. He has this to say about priming the battery:

Lithium-ion is a very clean system and does not need priming as nickel-based batteries do. The 1st charge is no different to the 5th or the 50th charge. Stickers instructing to charge the battery for 8 hours or more for the first time may be a leftover from the nickel battery days.
...
The charge process of a lithium-ion-polymer is similar to lithium-ion. These batteries use a gelled electrolyte to improve conductivity. In most cases, lithium-ion and lithium-ion-polymer share the same charger.

If Li-polymer batts required priming, I assume he would have said so. What do you think?

The battery doesn't need priming, but on many devices (and I don't know whether or not the Kindle is among them) it can take a couple of charge/discharge cycles to accurately calibrate the battery meter.

Indeed.
With a new Li-ion battery it's a good idea to deep-cycle by allowing 3 successive discharge--charges. Truer readings will follow.

Tastes differ.

Apparently it is quite a pleasant experience. I have been told by several people that it is quite a thrilling book most the time and that there are only several very technical passages that one could just jump over.

I have it on my "To be read soon" list. Even though I consider myself a nonbeliever, I think it will be a nice experience.


As to the topic, my kindle has discharged roundabout 25% since I got it, and I have 150 books on it now. But since the indexing has been done, the charge icon is stuck where it is, even though I read quite a bit already

you can disable indexing in xp and windows all flavours.

surely you can disable it on linux too?

no need for indexing contact apart from titles.

[whitearrow]

Because Amazon wants to keep things simple. The Kindle OS is not Windows or Linux.

You can click to see which they are, and if they seem to be stuck you can delete and reload one at a time.

Thanks for that info! I did the check and it appeared to be hung up on 83 books, almost all of them books I had bought from Amazon. I had transferred them from calibre and, apparently, the new Kindle didn't like that! The message I got if I tried to open those books was that they were licensed to another user, to delete them and download them from my archives. I just hope they weren't ones with messed up metadata!

Frankly, the main reason I purchased my Kindle 3 WiFi LG is because of the Bible. Amazon sells several Bibles with Direct Verse Jump (DVJ). That is especially valuable in Church services and Bible Studies. Pastors jump around a lot and turning pages of a pBible is just too cumbersome.

The first books I purchased after the K3 were the KJV and NET both having DVJ. The NET has 61,000 footnotes which the K3 neatly indexed for rapid location. I purchased a Bible dictionary as well which the K3 can make into the default dictionary just for Church.

Other books I read are over 800 print pages each and take a lot of time to finish. The first main book I am reading now on the K3 is: "Deliver Us from Evil: The Slavery Question in the Old South" by Lacy K. Ford. The other book I am reading now on my Sony PRS 900 is: "The First Tycoon: the Epic Life of Cornelius Vanderbilt" by T. J. Stiles. I read two at one time and do most of my reading on my PC using eReaders only away from my house.

Carrying already read books makes no sense to me. They just clutter up things. However, with the Kindle 3 keeping highlights and notes and able to search all books may change my doctrine. They may make old, read books, still have value as references. I find the Sony PRS 900 slowed immensely in proportion to the number of notes and highlights. The K3 is not slowed apparently no matter how many notes and highlights one maintains.

So far as the battery life goes, keeping the K3 in Shut Down Mode, not Sleep Mode, when not in use should conserve battery life way past its stipulated period. The battery on my PRS 900 is rated for one month but lasts way past 2 months using that doctrine.

If you truly understand the technology behind e-ink you'll realize that "shut down mode" doesn't save any more power than sleep mode. A tear down of the K2 indicated that when power was completely removed the screen continued to display the last image. That's the way it's designed to work. With Wi-Fi off and no indexing being done, the only time a Kindle uses power while reading is when it does a page turn. It doesn't operate like other electronic devices and there really is no "off".
