Here is the graph for yesterday/today...
during my hours at work u can see I was doing heavy usage throughout the day, surfing and texting through GV plugin over wifi, with gsm radio on and off at times to check my voice mails...
All settings like in my previous post, but also I was always connected to two Irc channels, one of which has medium to heavy traffic.

1:30 am got home, switched off gsm, left xchat on with the same channels and all other settings the same... all on wifi.
woke up an hour ago, turned on gsm, made a phone call, installed an app, I'm reading the forums now, and sending these posts with images etc...

**EDIT** Failed to add my screen is set to 3 brightness, I have 4 desktops enabled, and I have vibration turned off. And I was also running the facebook chat plugin during this time.
