Student's Antenna Tweak Leads to Vastly Improved Battery Life
Dec 19, 2008, 2:55 PM by Eric M. Zeman
A student at Canada's Carleton University has discovered a new way to drastically improve battery life on mobile phones by changing the way the antenna is connected to the device. The method eliminates all the wires used to connect the electronic circuit board of the phone with the antenna. Rather than wires, the antenna communicates with the circuit board via a small RF transmitter embedded in the circuit. The method reduces power draw on the battery by 12 times, and will be less-costly to produce when compared to traditionally wired configurations. The inventor, Atif Shamim, an electronics PhD student at Carleton University, has filed for patents on the technology.

Reception vs. Battery Life
My first question is how is the reception compared to a "wired" antenna? If the reception is less, then what good is a longer charge on the battery? Most phones kick up the power as the signal becomes weaker (to keep connection to the tower) until the handoff. Thus, if the reception is weaker with this new finding, then the extra battery power becomes moot.
with the saved battery life I'm sure they could have the antenna run at 100% all the time and still have a significantly longer lasting battery

I hope this works
12x times more battery life would be a big improvement for any 3g phone on the market. Especally with 4g right around the corner on Sprint's WiMax network. 😎

Why, does WiMax draw 12x the battery po...

I believe the article says it reduces the battery draw by 12x, referring to the amount of power the antenna draws. This will most likely not increase battery life 12-fold since the screen and other functionality will still draw quite a bit of power fr...

Thats why I said I hope this works. We wont know if it works until its actually tested till then I'll keep my fingers crossed. 😎

Kudos to This Person!
Whoever you are, you have made a huge discovery! As newer phones carry more apps and place greater demand on batteries used to power them, it's good to know that someone has made this amazing breakthrough.
Good job and props! 😁

Probably, but dying early is a part of cell phone ownership right? 🤣
I would be more concerned with living under an FM Radio tower than I would the emissions from a cell phone.

"Verizon said it will immediatly implement it in all its future phones and will start advertising it immediatly, however the feature will be disabled for the users protection" 🤣
Yeah if it don't have Verizon's brand name on it then they won't support it. I've been a Verizon customer for years and defended their network but I'm probably going to open my mind to AT&T and see how they work. I like wireless freedom and not havi...

This is a Wonderful advance
😁 This is a Wonderful advance and it will not take 10 years to implement... Think about it, probably under 2 years and this along with the Lithium battery advances coming down the pike could make daily charging into a Weekly charging system...
And the idea, has other applications including the blue tooth and other electronics. Not to mention the "James Bond" ideas this could help come to life...
I wish him well. Well done...

Good, not great
It sounds like 12x power savings is misleading. From reading the article, this won't be a 12x savings in total power. It won't even be a 12x savings in the power consumption of the transmitter (transmitter + power amplifier).
The student has reduced the power loss in the antenna/circuit board interface by 12x. The loss at this junction is just a fraction of the total power consumption of the device.
Power consumption is important, and every bit helps, so this sort of innovation is important, but it will be a much more incremental improvement than the article seems to suggest.
