Hands On with the HTC One X and Sense 4
Replying to: To Eric by MarryTheNight
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.
