Researchers working on 10x more efficient cellphone batteries
This inefficiency contributes to the growing amount of energy lost when gadgets and household appliances are put into standby mode. The plan is to use nanotechnology to "close" up the leaky transistors. Research on the new transistors is still under way, with a prototype expected to be ready sometime in 2015. If the research teams succeed in their aim of making such devices, they would use far less power than existing transistor designs which typically leak energy even when supposedly turned off.
Like a leaky faucet, today's transistors are never fully closed even when they're off. "It's old technology," Professor Adrian Ionescu from the school's Nanolab told The New York Times. "What we want to use is nanoscience and nanowires, so when you want to close it, you do close it. Our vision is to share this research to enable manufacturers to build the Holy Grail in electronics, a computer that utilizes negligible energy when it's in sleep mode, which we call the zero-watt PC."

Got something to say? Post a comment-
I hope this battery technology will materialize. We can definitely use more battery capacity as smartphones are getting bigger and more complex. By next year we will have dual core processors in smartphones. It's basically a mini computer! I find that battery technology has always lagged behind as compared to other technological advances. Look at laptops. No modern day laptops can claim 4 or 5 hrs of battery life. Netbooks can boast 6 to 8 hrs of batt life only because they use a strip down, low powered CPU (mainly single & dual core only). You're giving up CPU horse power for longer batt life.

They have been talking about making more efficient batteries for years and we have yet to see much come from it. I hope that they finally start to develop longer lasting more efficient batteries

This said the prototype wasn't going to be ready until 2015. It has a lot more than 1-3 years of a wait for something like this.

Yeah, this technology is so far off that its not worth deciding that you cant wait for it. While I agree with the poster who said that battery technology has lagged behind every other aspect of technology, all we can do now is move towards a more efficient state, however long that takes. The effects of paying less attention to battery power will still be felt for another couple years, at least.

Nansistors, yay! That would be awesome, but hopefully business politics won't interfere with it. Imagine the battery companies losing money because they aren't selling as many battery cells.
-
not only more efficient, but more durable please.
-
This would be awesome if it actually got out to the public. We hear about so many cool pieces of tech that would just revolutionize portable electronics, but its always the same old thing.
-
10% is good for now there needs to be more work juice they can squeeze out of the new batteries even for the phones because the phones are doing alot more than years ago
-
really doubt whether they would be commercially viable...
even if they come they would be expensive and by the time it becomes cheap we would be literally carrying smart-computers not smart phones...
-
It's always interesting to read what people's opinions are about things. That's why I think the comments on stories is great. It really opens your eyes to how others think compared to you.

Sounds great but let´s face the truth, we still have to wait few more years plus I´m really curious about the retail price...it´s really a shame that batteries are the very last components that are being innovated, when you compare them to displays or processors for example
-
good news, smart phone nowadays really battery hungry

How awesome would it be to have a battery that could last!
How many times has your battery died before lunch time. It seems as though the technology the battery provides power for has taken precedence over the power that provides the technology.
I think we've all been waiting for advancement in battery life, and it looks like we have to wait a little while longer.

now our phones will cost an additional $100.........
-
yes the current batteries look outdated nowadays in comparison to the fast evolving technology of chips and networks...
