Yeah, but it's still extremely impressive given the upgrade in capability. I'm sure a designer has to make major compromises to optimize for battery life to level of the original. Though, for something like this, it might have made more sense to target something like the Casio W800H-1AV; which is another cheap classic Casio, but it has a bigger battery, more display capability, and a 4th button.
