Notable exception would be cordless phones. Their batteries seem to last 2 years or so (NiCad). How long do you most people keep cellphones/mp3 players laptops? While some exceed 5 years, I think that's a small group. I think this would be great for hybrid and electric cars]]>Apr 7th 2010 3:18AMhttp://www.engadget.com/2010/04/07/hitachi-claims-secret-chemical-formula-will-improve-cathodes-do/http://www.engadget.com/2010/04/07/hitachi-claims-secret-chemical-formula-will-improve-cathodes-do/
oh. better example. i've had a play-and-charge kit for my xbox 360 for almost 4.5 years. that battery lasts at best 1/3 the time it did when i bought it new. also, many people are speculating that the new generation of consoles won't come until about 2015, which would give the 360 a life of about 10 years. the next generation of consoles might last even longer. there are plenty of uses for this tech. not to mention, if it makes batteries cheaper too, why not?]]>Apr 7th 2010 3:32AMhttp://www.engadget.com/2010/04/07/hitachi-claims-secret-chemical-formula-will-improve-cathodes-do/http://www.engadget.com/2010/04/07/hitachi-claims-secret-chemical-formula-will-improve-cathodes-do/
Yup... When I first got my laptop, I was actually getting the advertised eight hours of life from the battery... just seven months later, it's probably closer to six (though I'd probably get more time if I didn't leave my browser open with 20 tabs all the time). At this rate, I'm gonna have to drop $70 on some sketchy off-brand replacement (Acer doesn't seem to have batteries for my model for sale).]]>Apr 7th 2010 11:03AMhttp://www.engadget.com/2010/04/07/hitachi-claims-secret-chemical-formula-will-improve-cathodes-do/http://www.engadget.com/2010/04/07/hitachi-claims-secret-chemical-formula-will-improve-cathodes-do/Apr 7th 2010 12:27PMhttp://www.engadget.com/2010/04/07/hitachi-claims-secret-chemical-formula-will-improve-cathodes-do/http://www.engadget.com/2010/04/07/hitachi-claims-secret-chemical-formula-will-improve-cathodes-do/]:]]>Apr 7th 2010 3:29AMhttp://www.engadget.com/2010/04/07/hitachi-claims-secret-chemical-formula-will-improve-cathodes-do/http://www.engadget.com/2010/04/07/hitachi-claims-secret-chemical-formula-will-improve-cathodes-do/Apr 7th 2010 3:59AMhttp://www.engadget.com/2010/04/07/hitachi-claims-secret-chemical-formula-will-improve-cathodes-do/http://www.engadget.com/2010/04/07/hitachi-claims-secret-chemical-formula-will-improve-cathodes-do/like a day*]]>Apr 7th 2010 4:00AMhttp://www.engadget.com/2010/04/07/hitachi-claims-secret-chemical-formula-will-improve-cathodes-do/http://www.engadget.com/2010/04/07/hitachi-claims-secret-chemical-formula-will-improve-cathodes-do/

Laptops on the other hand have gotten quite a bit better (I have an old Toshiba laptop from 3 or 4 years ago that only gets a pitiful 1.5 hours of battery life, and that's unheard of these days). But as more and more people adopt smart phones, MIDs, and tablets, we're going to need better battery performance.

Seriously, fuck putting a 2.0 GHz Snapdragon and 2GB of RAM into the latest and greatest smartphone. How about a battery that isn't destined to die before noon if it isn't fully charged the night before?]]>Apr 7th 2010 12:15PMhttp://www.engadget.com/2010/04/07/hitachi-claims-secret-chemical-formula-will-improve-cathodes-do/http://www.engadget.com/2010/04/07/hitachi-claims-secret-chemical-formula-will-improve-cathodes-do/
Either better battery performance or - probably more likely - better processor performance. For instance, except for gamers, most people can now be perfectly happy using desktop PCs which run relatively low-power CPUs (compared to the fastest CPUs, that is). And netbooks run on chips that use 2W compared to 65W+ for desktop chips, and though they're noticeably slower (about like a 5-year-old desktop?), you know, they're really pretty much okay for a small portable computer.

Haven't quite reached that level yet with smartphones, but it probably isn't too far off. (I mean, lots of phones today can play 720p video without breaking a sweat, and we *really* don't need phones to do that.) Give it another couple years and the power requirements for something with a Cortex A9 - which like bill gates said, should be enough for anyone - will be lower than current high-end phones. Screens are getting more efficient too.

(Reduced power consumption will also mean smaller batteries are good enough, which means those of us who don't like the current large phones can get smaller phones that are still 'smart'; and with smaller screens, which use less power too...)

In summary, typically battery performance improves a lot less quickly than processor performance, so I'd plan on phones that use less power sooner than batteries which provide more. And take any claimed battery improvements with a pinch of salt. Would certainly be nice if phone batteries worked for more than a couple years though...
