I read a couple of other sites that had previously mentioned the infrared sensor being active for Siri. I still think there is a flaw in the programing that keeps this sensor active whenever the screen is on-even if Siri is turned off. When Apple is under the gun to make the 4S live up to it's battery claims, I would like to know why they have the phone designed this way. Even if it required 3% cpu usage to monitor, it's a waste.
Actually, the sensor is really easy to see with a facetime camera on my iPad or MBP (which pick up infra-red), and I can confirm it is only on when the screen is active. It switches off when the screen is off.
And of course, if you don't like the feature, as it undoubtedly does drain battery, then just turn it off. The setting is right there...
That's the issue. The IR source stays on after turning Siri off and rebooting the phone. I tested that yesterday.

Even on 5.0.1? Wow. My bad.
What setting? The screen? You can not turn off the sensor on the 4S while the screen is on.
Apple messed up. And while the IR source may not be drawing a lot of power, I am really curious what app gets loaded to monitor its function while on and how much power that app is using.
It is supposed to turn off with Settings > General > Siri > Raise to Speak OFF, but I was unaware that was not fixed.

NewdestinyX said:No, Rocko. No JB for 5.0.1. And there won't be for quite some time. They barely found the firmware exploit in 5.0 recently and Apple plugged that tight in 5.0.1. And now the window is closed to downgrade to 5.0. If you're still at 5.0 and can live with the battery thing - STAY there. From all I'm reading jailbreaks to ios5 will be much harder and longer to wait to get them.
Do you think the proximity sensor and some unknown app is behind the battery drain?
