The great thing about new flagship phones is that they often comes with new features we can all get excited about. The Galaxy Note 3, announced a few days ago, is no exception. While Samsung made a point of featuring Category 4 LTE with Carrier Aggregation, which can achieve 150 Mbps, the company neglected to mention the Note 3 also includes the Qualcomm QFE1100 chipset which should significantly reduce power consumption and heat associated with the LTE radio.
Qualcomm achieves these enhancements in the QFE1100 by using a technology called Envelope Tracking. Essentially, the hardware tracks changes in the radio frequency and adjusts the power amplifier accordingly. Unlike traditional methods which perpetually run at full power, this technology can limit power usage only to what is necessary at the moment of transmission. This reduces the amount of energy consumed for communication and significantly reduces unnecessary power consumption that results in heating. Qualcomm claims this can reduce radio power consumption by up to 20% and heat production by up to 30%, all while improving the speed and reliability of the cellular signal.
Considering the Note family already has a reputation for great battery life, this can only make it better. Based on Qualcomm’s marketing, it seems likely that only the LTE-enabled Note 3 will be equipped with the Envelope Tracking technology.
