No screen usage equals longer battery charge. But if you turn on the LCD, which after all is what makes the iPt4 worth having, then the time goes down exponentially. I see that @LiquidGear has the same issue of short battery charge, as do lots of people judging from the huge numbers of complaints over the past two years. After all that Retina display requires a lot of energy, so they need to add a larger capacity battery.

And for the record, my iPad 3 battery runs down a heck of lot faster than the 6 to 8 hours advertised. I haven't run it down all the way to 20% yet, but it easily depletes to 50% in 2 hous or less when reading with the screen brightness at about 30% (somewhat dim).
