The guys over at Kotaku have listed all of the DS Lite and newly announced DSi specs in a one-on-one showdown. We see all of the expected small upgrades—the screens are a tiny bit bigger, the case ever so slightly longer and thinner. But the big surprise? Battery life bites it big time.

On low brightness, the DS Lite was rated at 15-19 hours of life. The DSi gets only 9-14 in the same conditions. That's a loss of 5-6 hours. Higher brightnesses show less battery loss for the DSi, ranging from 1-5 hours less on "high brightness" and stabilizing to a 1-2 hour reduction on "highest brightness."

Well, no reason you can't get an extra battery, but that doesn't mean Nintendo won't be fixing it either. So let's just wait.
