Thanks for the feedback, NuggetHoarder. Some interesting observations.

The revelation the other day that the new Android 4.3 will continue scanning for Wifi nodes by default even when Wifi is turned off reminds me that "features" are not always what they seem to be. Google seems like it is sacrificing battery life (your battery life) with this default setting but I guess they feel like they are gaining something in return by gathering location and metadata about Wifi hotspots from "everyone"

At over $4 a minute, I wasn't willing to risk it. The battery came out and stayed out.

I'm no expert on Android but in Airplane Mode the radios are supposed to be turned completely off for FAA regulatory compliance.

I'd be pretty steamed, though, if I turned WiFi off and it didn't turn off.

That's a good point about airplane mode and I don't know if this "feature" applies when airplane mode is turned on, but if wifi is turned off, it's actually still secretly on by default unless you go in and change a sub-setting. I believe these guys were the first to report on this behavior of version 4.3 here.

From Arney's link:
Quote:
...Google wants you to leave your Wi-Fi on, or at least partially on, all the time. Now I know you might immediately scream "MY BATTERY LIFES!!11" but this will probably save battery. Google wants you to leave Wi-Fi on so that apps can get your location, but consider that the other option for location is firing up the GPS chip, which is a battery's worst enemy. ...

Hmmm, WiFi transceiver uses less battery power than a GPS receiver? I'm thinking that transmitting and receiving is a bigger battery drain than just receiving, but maybe the GPS chip is a power hog relative to a low powered WiFi -- dunno. Anybody know the answer?

BTW, another option is to turn location services OFF.
