So I've had few issues after my upgrade to ics, (followed the dark Knight recommended full wipe), but wifi has been killing my batt. If set to "always on", it's on when my phone sleeps. If set to "only on when charging" it disconnects damn near constantly while I'm using it. My fix was this:
1. Set wifi to always on, (wifi settings, hit the menu button, select "advanced")
2.in Llama, (you DO have llama right? If not, download it now, best app out there), set a condition for "when at home and screen on, turn on wifi"
3. Set another for "when at home and screen off, turn off wifi"
You can do the same for any other location where you regularly use wifi. This way, as soon as my screen comes on, my wifi comes on. It shuts off when my screen does. Connection quality is great and uninterrupted when I'm using it.
Hope this helps someone.
