A smaller battery isn't necessarily bad news. Perhaps Samsung made enough power management improvements that they no longer need such a large battery. A smaller battery means less weight, smaller form factor (or more room for other advancements in the same form factor) and lower cost. So long as the battery capacity is commensurate with the power demand, so it can comfortably get through the day, over a period of 2-3 years, before I charge it at night, then I'm happy.
