[Engadget]Student's tech promises 12x the battery life in your iPhone, BlackBerry

post #1 of 12
Thread Starter 

Feeling the hurt of endlessly dying batteries on your BlackBerry (or iPhone, if that's what you're into)? Atif Shamim, a PhD student at Canada's Carleton University might have the medicine for that pain of yours. He's cleverly hacked such devices, removing all the wires that connect the electrical circuits to the antenna, and developed a module for the connection to operate wirelessly. The result, he estimates, is that his modified devices use almost 12 times less power than they normally do -- which of course means longer battery life. A paper about the device has won an award at the European Wireless Technology Conference, and Shamin has filed for a patent in both the US and Canada. There's no indication of when we might start to see tech like this on actual commercial devices, but we're pretty sure plenty of companies are going to want to get a hold of this technology like, yesterday.

So...our wireless phones are...now wireless?

The power source will become wireless, as opposed to batteries.

Wait what? I'm confused.

This has to be a joke.

Basically, they are saying that there are no wired connections attached to the antenna. So there has to be a transmitter from the phone that transmits the signal to a modulator for the antenna, and then used the antenna to transmit the signal!?!?!?!

Almost sounds like it requires more circuitry, but who knows that article just sucks and doesnt say enough.

I think what they are implying is that he made the transmitter it's own separate wireless module with it's own power source, so that the power hungry transmitter won't drain your device and the device won't drain the transmitters new batteries.

Yeh, but at the end of the day, the antenna is still being used, and youre adding in more circuitry, which will use more power.

I am wondering the writer was completely drunk when he wrote this and he meant to write about how people are trying to use antenna's to receive all the signals that surround us and charge phones with them.

I always did wonder why those things' batteries died so quickly. Lots of other smartphones last for 1week+ without needing a charge.
