Back when the 4S came out I heard lots of theories around why *some* people had bad battery life, and one of the things people commonly turned off was Siri's "raise to speak" on the theory that it was using a lot of power to run either the proximity sensor or the accelerometer or both. I can't find any evidence on the interwebs that this was ever proven to *actually* be an issue, but.. Does anyone know if this feature is now considered "is/is-not a battery hog" on the new iPhone 5 and/or iOS 6 in general? Did they improve it? Are you using it? I'm torn because for some reason Apple has certain features only work the way I'd expect if this is ON. For example: With raise to speak ON, if i hold it to my ear and ask for the nearby restaurants, Siri tells me all about them in my ear. If I have raise to speak OFF, I can still get Siri to tell me that there *are* restaurants nearby (in my ear, once I've activated it and THEN put it to my ear) but she then won't speak them - but rather displays them.
