Boffin hacks Wi-Fi to double mobile gadget battery life
Want to significantly boost your smartphone's battery life? US Duke University researcher Justin Manweiler reckons he's worked out how. Manweiler's work centres on Wi-Fi, specifically when the phone - or tablet or laptop, for that matter - is operating within range of more than one wireless access point. If access points are …

Zzzzzz
I went into sleep mode about halfway through the explanation.
Anti-climax
There's me going into the article thinking of some quirky code to be inserted into the WiFi function to make my phone last 3 times as long and all I got was a three page article summarised into "less WiFi = more battery".
Nice!
Awesome idea. And kudos for releasing it in an academic paper, rather than immediately attempting to patent it.
Probably a dumb question...
...but can't the phone periodically check your connected AP and /ignore/ all the others?
It's something to do ...
... with having to open the box to see what's in the box, or the cat will die.
What does it take to impress people these days ?
A neat elegant efficient idea. Openly shared .. I thought that sort of thing had died out.
And yet people respond with "meh" ?
You probably should go back to commercial TV.
Their content is undoubtedly more suited to your attention span.
Logical but really it's nothing new
Logical but, I'm afraid the fundamental principle has been around GSM handsets for ten years plus. Wake the device up less == less power consumption. I like hayrick's idea, needs further investigation. Could be even be optional thing "When authorised on one hotspot ignore others to increase battery life", check.
So how long is the sleep then?
What I didn't get from the article is how long does my WiFi radio sleep between calls on average vs this new method?
Are we talking millisecond-level intervals of swithcing power to the rado on and off? Just curious...

Someone get this very clever bloke a pint. Sounds like this idea could be a runner...
Nothing new...
Old tech.. My company has been doing this with our WiFi equipment and Clients for the last 9 years.
In fact our WiFi clients run in a single lithium cell battery for 6-8 months before they need re-charging.
Lo-Q.
