I've noticed lately that my Kindle is chewing through its charge at an alarming rate. I don't leave the wireless on, so ideally it should be good for 10 days or so. At a minimum it should last for 7 days. My most recent charge lasted 4 days.
So today I called Amazon customer service. Apparently, I have an astonishing number of files on my Kindle, more than almost anyone the rep has seen in the 3 years he's worked for Amazon. There were only 837 files on my Kindle at the time, almost half of them samples. And the K2 (the version I have) is supposed to hold 1,500 books. So even if a sample takes up as much space as an entire ebook, I'm still only a little over half full.
I didn't really understand all the tech-speak, but I guess the problem isn't the number of files on my Kindle per se. The problem is with one of the 837 files. There's a glitch in one of them, and it's making the Kindle continuously try to index itself, which is eating up power. Supposedly there's no way to figure out which file it is, so the only thing to do is delete as many excess files as possible. Either the bad file will be deleted and the problem will stop, or with fewer files it will spend less time indexing. As the number of files goes down, hopefully the battery life will go up.
I accept that there's probably no way to know for sure which file is causing the problem, but this still annoys me. I barely ever leave my room, let alone the house, so it's not like I'm ever in great danger of being Kindle-less. But the charge really should last longer, and I don't want to have to clear that much stuff off my Kindle!
It kind of boggles me that the customer service guy was so surprised by the number of samples I have. I can't be the only weirdo who uses her Kindle the way I do. I find shopping directly from the Kindle to be a bit of a pain. Also, I spend a lot of time cruising around reading websites, so I probably hear about another 2-3 books I want to check out every day. I pop on over to Amazon, download the sample, and move on with my day. When I want a new book I go through the samples until I find something interesting, and then with a couple of clicks I can purchase directly from the Kindle. I can be anywhere to do this, including a doctor's office or the bathroom (prime book buying locations for me, btw). As far as I know, the Kindle can't tap in to your Amazon wishlist, so adding all those books I'm interested in to my wishlist just won't work as well for me. (I do wishlist books that haven't been released yet, since there are no samples for those. Then, I check the wishlist every once in a while, and anything I'm still interested in I'll sample.)
I spent a good bit of my reading time today working my way through samples and deleting books that I didn't love and won't be reading again. But the rest of my day was spent trolling Goodreads and adding more samples. So I'm only down to 829 items-- a net decrease of 8 files. Unless I got really lucky and deleted the problem file, I'm pretty sure that's not going to make a difference to my battery life. I guess I'm going to have to spend the next couple of days reading samples. That's fun in its own way, I guess, but I'd rather do it on my own schedule!
