Sensationalist headline alert: They forgot to finish the sentence with "if you leave Wi-Fi turned on".

How many people actually bother to turn their WiFi off? I don't know of any who do it manually (although I do have Juice Defender to do it for me, based on location).

I don't turn WiFi on. It wastes battery life, and I don't download enough to worry about caps etc.

PS: I also tend to go a few days between charges so my usage patterns are far from the norm.

I do. I believe it saves battery, and it's really quick. In Touchwiz, the WiFi/GPS/4G controls are built into the notification pulldown. I believe the same is true of cyanogenmod.

Having it automated might be better, but it's never bothered me enough to look into that.

It only saves battery if your wifi is continuously scanning and not actually getting on a network. Otherwise, wifi is preferable to using a mobile network for data traffic as far as battery life is concerned.

WiFi is a big battery hog on my phone. I can go three days on one charge without it, but if I connect up to my home network with WiFi I get less than two.

Are you running an app that's configured to perform a particularly data-intensive activity only on wifi? That's the only way I can reconcile your experience with ryandvm's comment (sibling to yours).

Nope. That's with virtually no data usage at all. Just turning it on and connecting to my home network.

I run CyanogenMod, and have the pull-down. I agree that it saves battery. I probably wouldn't bother turning WiFi on and off manually though -- and my wife definitely wouldn't (and didn't, before I set up JD on her phone). That's why I like Juice Defender...

Funny. I don't know of any who don't do it manually.

And it's not easy to identify you...yet. I thought about rewriting the headline, but stuck with the original guidelines and didn't.

Good for you, though as we can see the no-tampering-with-the-original-headline rule definitely comes with tradeoffs.

Gosh, for the nth time, there is no "don't tamper with the original headline" rule. There's just a "don't sensationalize headlines" rule.

ComputerGuru is right. From the guidelines:

You can make up a new title if you want, but if you put gratuitous editorial spin on it, the editors may rewrite it.

Absolutely. Oversimplified to the point of being false.

I'd have thought this would be fairly easy to do, you just need a sufficient amount of WiFi access points. Someone should add this DD-WRT or Tomato so it can be done with cheap/consumer routers easily.

Sensationalist headline alert: It's hardly "anyone". The title makes it sounds like I could track your every move.
