something is seriously wrong with my battery.
took 3.5 hours to charge to 100% and now I'm 40 minutes off the charger and down to 70%.
There was 1 10minute GTalk video call in there.. but otherwise just basic stuff, webpages texting etc.
also, my display is 32%... I have it on auto dimming
Try to drain battery all the way down again and recharge and see if it still does the same.
