More Kindle Battery Advice

And another thing about the Kindle battery: I only charge with the wall socket adapter. I plugged the USB cord into my computer and let it charge while in sleep mode one day, and it actually ran out of power while it was supposed to be charging! Maybe this approach to charging would work if the Kindle was in the “off” position, but it was discouraging to see the battery go dead while connected to a power source under any conditions.

Oh, yeah, even plugged in to the wall, I find that my Kindle charges faster when in the “off” position. That’s recommended (by me).

The rule of thumb is that if you are not 1) using your Kindle like an iPod, 2) using an SD card with a couple thousand books on it, or 3) leaving the whispernet on all day, then anything short of three or four days on a charge is abnormal and should be reported to the authorities immediately.

From what I hear, they will replace the faulty battery for you.

    Issue isn’t having a particular type of SD card inserted according to Tech Support. It’s the fact that the Kindle is designed such that it CONSTANTLY re-indexes the contents of the SD card. Personally, I have well over 2000 books that I picked up for Palm Reader over the years. If I insert a card with NOTHING installed, the battery will last for a week. If I install THE SAME card with all 2000 books on it, the Kindle will die after 4-5 hours on STANDBY with the wireless link turned OFF (i.e., nothing SHOULD be drawing power). To me, this is the most ridiculous design flaw I’ve ever heard of–Tech Support’s response is not to use the SD slot and simply swap books in and out of main memory. Fine, but if that is the case, why the hell include the SD slot in the first place???? Personally, I think I was suckered into buying the damned thing based on the fact that it could hold my entire library, when what they actually meant was that it could hold my entire library as long as I wasn’t interested in actually READING it. Heck, I could have done THAT with a $5 SD card!

    After going back and forth with Amazon for a few months with a Kindle whose battery often could not hold a charge, a manager in their tech support group finally told me today that the SD card I am using was causing the problem.

    According to this manager, mini-SD cards are not supported and *will definitely* cause problems with battery life, and I was using a mini-SD card. Tech support has also indicated that some other SD cards might cause problems.

    To me, it seems safest at this point to only use an SD card bought directly from the Kindle accessories page ( Amazon even decided to send me a new, supported SD card free of charge, since the problem continued without resolution as long as it did.

    I am testing now without the mini-SD card (i.e., just using main memory), to see how things go.
