Ditto that. I've seen that on both my current Android and the Palm I had previously.
One other thing concerning wireless. We use WPA2 Enterprise. My Droid (HTC Incredible) had a credentials storage password. Every reboot required that I enter that password before the 802.1X credentials were provided for wireless. Continually trying to associate and failing before I entered that password would drain my battery quickly. That behavior seems to have changed on one of the recent updates.

Ask him to turn off wifi for a day and see if battery life improves, my guess is that it won't be much better. On 07/08/2012 10:26 PM, Scott Smith wrote: I have not seen such an issue, yet. I have seen that our campus buildings "suck" the battery life as the cellular signal levels are very low and in-turn the Android device is searching their primary signal carrier all day. I'm not at all dismissing your question or the possibility of this happening, I'm just putting out there what I've seen so far in our buildings. If I get other reports I'll let you know.

He claims his droid lasts all weekend on his home wireless, but runs down in a day on our campus. I'm not sure why this would be, assuming he runs the same apps all the time. My only thought was that his wi-fi driver was actively scanning (aggressive roaming) the other access points he would see here looking for better signal.

The issue is being seen when you install a type of bandwidth meter app on the device. The one I use is android status and I look at the network section to see the Rx and Tx statistics. Once connected to wireless the device still receives bursts of traffic, at least according to the app on the device. We are cisco wifi shop and I'm running 7.2mr1 code on the wlc's. Has anyone else heard or seen this issue? I found this post http://forum.xda-developers.com/showthread.php?t=1738171 which states... This is simply because your wifi antenna still "hears" the data going through the wireless network on which you are connecter. Even if your phone doesn't asks for any data at the moment the traffic there is on the network will still be counted by the wifi chip on your phone. It will be the same on any public network or if you have another phone or a computer connecter on the same wireless router and generating traffic. I have tried to increase the DTIM setting on one of the wlans and it didn't help. Any suggestions?
