    Based on 9to5Mac's article here, it appears that "The iPhone 4S has a neurotic tendency of always wondering how close your face is. As long as the screen is activated, that IR sensor will be shining brightly. Siri is ready and waiting to answer her master’s beck and call at any time. So whenever the screen is active, the proximity sensor is active too. Thus, whenever you raise the iPhone 4S to your face, Siri is ready to take orders."

    I've since then disabled the raise to speak function of Siri. I'm just OCD about having something always on that I don't actually use. :) Didn't like how they described "shining brightly" and "at any time" seems like this would use more battery. I don't think it uses that much battery, but since I don't use the feature, I'll turn it off anyways. Just sharing this to those that are in the same boat.

    You can disable the raise to speak by going into Settings -> General - > Siri.

    #2 think it will use more battery but also think it won't use more battery? Good times.

    What I meant was that, it will use more battery, but the additional battery usage should be minimal.

    English is my second language.

    I use it, works fine. I doubt the proximity sensor takes more than 1% away after a days use

    Don't worry, it was clear enough what you meant :)

    Personally I don't worry about it; the thing has a proximity sensor anyway/my iPhone 4/3 both did too.
