Hands On with the HTC One X and Sense 4

Well, the big things with the Snapdragon S4 chip in AT&T's One X is that it puts the processor and LTE modem on one chip, which should help battery life enormously.

Most Qualcomm chips do put the modem and processor on one chip, which helps battery life and size. But Qualcomm hasn't made such a chip with LTE before now. That's why LTE phones have been known for large size and having poor battery life; they had to cram two big, power-hungry chips in there.

But this year, phones like the One X with a single Snapdragon S4 should be smaller and more power-efficient.
