Thanks to a new Qualcomm chip, buyers of the Galaxy Note 3 will be able to keep the 4G pedal to the metal without sacrificing endurance. The reduced power draw should also allow the Galaxy Note 3 to run much cooler than comparable devices.
This new chip is called an envelope tracker, and Qualcomm says that it reduces the amount of power the Galaxy Note 3 uses to maintain an LTE connection by 30%. LTE requires a high-powered amplifier to keep its signal clean enough to use. The mobile signal waveform oscillates, though, and current devices output a wide, linear envelope that can catch its highest peaks. Qualcomm’s tracker matches up the envelope with the LTE waveform — so the radio draws less power when the peaks are smaller.
