Nov 19, 2011 2:37 PM in response to megakai132by philter123,Wow. I also managed to reproduce the problem. Here is what I did. I noticed the purple light with a seperate camera. Then I turned off Siri altogether but the light was still on. Then I did a hard reset and the purple light is now off. Fingers crossed. Also, I noticed that my bluetooth setting was on but I never use it and the bluetooth indicator was never on the status bar section(next to battery percentage on home screen).

Nov 19, 2011 2:47 PM in response to philter123by drStrangeP0rk,Glad to see that you got a 4s,
What ever happened, did you get that second hand iphone?
Note, the previous post about resets.Thanks and best of luck. -
Nov 19, 2011 2:50 PM in response to megakai132by drStrangeP0rk,This is know, with a cheap camera you can see infra red, like on the phone. Not a issue, make sure to do the resets and than the recharge.
Again, no 5.0.2 released to developers
Thanks and best of luck.

Nope..
This is normal. Try the recommendations related to resetting, make sure that your first charge is 24 hours.
Good Luck and Thanks

Nov 19, 2011 2:58 PM in response to megakai132by Steve2828,This is simply the "Raise to Speak" Siri sensor. It's not a "problem" or "malfunction" or "defect" or anything like that.
When you have Siri "Raise to Speak" on, that sensor is active whenever your phone is unlocked. That sensor detects when your phone is next to your face and makes siri listen automatically.
Also, when you are on a call, there is another similar sensor that is used to shut off the screen when you put the phone to your ear.

Nov 19, 2011 6:29 PM in response to Steve2828by MacDevil7334,Steve, the issue is that the proximity sensor is remaining active even when the Raise to Speak option is disabled in the Settings app. I have been able to reproduce this issue on my phone as well. I don't know whether or not this sensor consumes enough power to account for the poor battery life I am seeing on my phone. But, there is no reason this sensor should be active if Raise to Speak is disabled.

Nov 19, 2011 7:27 PM in response to MacDevil7334by Galaxyboyx,Exactly. Why is it even on when Siri is off or Raise to Speak is off?
Whatever it is, just raise this up to Apple and let them know about it.
Whether they reject or not, at least we've tried.

Nov 19, 2011 7:50 PM in response to megakai132by Galaxyboyx,If this is the cause, that does not explain why those using iPhone 4 is experiencing battery drain after the iOS 5.0.1 update.
iPhone 4 does not have battery problem before, only antenna.
Do not scare youself, it may not be hardware bug.

Nov 19, 2011 8:25 PM in response to megakai132by mkiitmr2,I tried it on my iphone 4s too. I used the front facing camera on my ipad2 to check it. You can clearly see it lit up when raise to speak is ON, then I turn OFF raise to speak and it still lights up. So I think you are correct this is a bug.
Also, I found that if I toggle the siri raise to speak off, then I power down the iphone and power it back on, it will turn off, so no need to fully drain battery I guess. I'm curious to see if this helps my battery. Thanks.

Nov 19, 2011 9:04 PM in response to megakai132by W. Raider,I've noted the same thing with my iPhone 4s and my GF's. We've both turned off Siri and then rebooted our iPhone 4s's so we'll see how this affects battery life since I have a very good since of how fast it drains.
You can EASILY see the light with the front facing camera on an iPad2. I noticed that the light comes ON when you intimate a call, blinks faster when you put your hand over it as if your face is there and then turns OFF whe you end the call.
A phone you call, in this case my GF's iPhone 4s, will turn this light on when it receives a call, then OFF when the call is over. Fingers crossed!

Nov 19, 2011 9:08 PM in response to drStrangeP0rkby W. Raider,No, the sensor is only on when you make or receive a call or Siri is on. Tested on two iPhone 4s's and both show same behavior.
I can activate the screen on both phones and the sensor remains off until a call is made or received. This is after turning Siri off e rebooting and verifying the light is off.

Nov 19, 2011 9:16 PM in response to W. Raiderby JPBOSS,Ok, so here's what I have found. This does in fact prove that there is a bug and it's fairly easy to replicate on the iPhone 4S.
Turn on Siri Raise to speak. IR sensor is active. Turn off Siri Raise to speak, IR still on (should be off.)
Do a graceful power off of phone, power back up and IR sensor is now off when screen is on/lit.
Now, here is where it gets interesting.
Do another graceful power off. After phone is off. Do a two button power cycle holding both buttons continuously until Apple logo comes up and dissapeares twice. Now the phone is fully off. Now, power the phone back up. You will see the IR sensor come back on from a cold boot for some odd reason and it makes no sense. Why would a warm boot cause the sensor to act diiferently than a cold boot?
Don't flame unless you understand the difference between a warm power cycle and a full power cycle on an iDevice.

Nov 19, 2011 9:18 PM in response to philter123by Terrence Mcatamney,It's a bug. The light stays on regardless. http://macsmind.com/wordpress/2011/11/14/iphone-4s-battery-drain-due-to-infrared -sensor-staying-on-even-when-not-needed/

Nov 19, 2011 9:21 PM in response to JPBOSSby JPBOSS,Let me also clarify and add that this IR sensor behavior is not the "Phantom" drainage some folks are having but could cause increased batt. depletion during the course of using the phone normally if you indeed wanted Siri raise to speak turned off.
