My gut feeling is that my iPad3 discharges the battery slightly faster than my iPad2. My daily iPad routine is very consistent and I replaced the iPad2 with the iPad3. I am not unhappy at all with its battery life. I may do back to back comparison. I noticed that the display on the iPad 3 needs to be at least 30% for the color to look normal. The iPad2 had a more linear dimming effect. Above 40% the new iPad blows the iPad2 away. Bellow 35%, the iPad 2 looks more accurate.
