WOW, The Kindle's battery life doubles overnight
it is magical.

apparently Amazon not to be out done with how to caluclate and stretch the spec sheets now claims the Kindle has 2 month battery life.

http://reviews.cnet.com/8301-18438_7...?tag=cnetRiver

Does anyone really take the battery life specs on any device totally serious anymore?

I'm happy with the extended battery life of my Kindle but there is no way it would last for a full month never mind two.

I know I don't. You can calculate it any way you want to make it seem longer than it is in practical use, but marketing folks keep doing it so I suppose some folks must take it seriously. It's kinda like printer and copier manufacturers when they tell you you'll get X number of copies out of a toner cartridge.


The battery on my Kindle might last 2 months if I hardly read on it. As it stands in practical use I get about a week with WiFi off and reading quite a bit. I'd expect I'd get similar from the nook.

battery life is to ereader specs to what contrast ratio is to HDTV specs. You hope for a somewhat ballpark figure but don't think in the least they are accurate or not fudge

so I think it's safe to say you'll get a good battery life out of these and call it a day.

but this does go to show you Amazon is keeping a very very close eye on BN and maybe a bit worried as well.

A single charge lasts up to two months with wireless off based upon a half-hour of daily reading time. If you read for one hour a day, you will get battery life of up to one month.
That sounds about right. I haven't been reading much at all lately, and it's lasted me about 1.5 months so far (wireless turned off). They were trying to make it an apples-to-apples comparison, which I can't fault them for, but really it only makes sense to include the blurb above when talking battery life. When I'm really into reading, I'm lucky if the K3 lasts a week without a charge.

I'd say so.

B&N has to be their closest competitor so I'd hope they're keeping an eye on them, I'm sure B&N does the same with Amazon.

No, not in the slightest. I'll read them, and I take them with a grain of salt.

Battery life based on minutes per day of reading time.

Amz (old): 1 month = 60 min/day = 30 hours

B&N (new): 2 months = 30 min/day = 30 hours

Amz (new): 2 months = 30 min/day = 30 hours

When Amazon releases the Kindle Touch later this year, I fully expect a 4 month battery life (15 min/day = 30 hours)

Isn't marketing great? Personally I still prefer knowing the number of page turns, but that seems to be dying out.

I don't pay too much attention to battery life. Most of my reading is done at home where I have a wall outlet and I don't take 8+ hour flights either. Since practically every eReader I've tried gets ~8 or more hours of reading time, battery life isn't a factor for me.

I'm not surprised. Last summer when B&N dropped the price of the 3G model and debuted the Wifi model, Amazon dropped their prices by exactly $10 within hours. :P

I don't think it shows any fear on Amazon's part to keep up with B&N. Apparently, the power draw and battery capacity are the same for both devices, and B&N was trying to pull a marketing advantage, so Amazon countered. I don't especially like it but I understand it and don't think it shows fear.

Also, with more people expecting to use other features, like wifi for shopping and social features, etc, I don't think page turns would be a very valid measure of battery life anymore, either. People will be doing a lot more than turning pages.

I like that way too, and Kudos to Kobo for using that method.
