I have started getting complaints from users regarding battery life on android devices when connected to our campus wifi. 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?
