I don't know if this is an issue, but I've noticed ever since I got my phone in December that the display brightness dims and brightens very frequently, especially if I'm playing Angry Birds. I have my brightness settings on auto. Also I noticed yesterday that when I click on "battery use" I see that 96% of the usage is for the display and 3% is for cell standby. Is this normal to have that much battery usage for the display?
