Qualcomm QFE1100 Envelope Tracking Chip To Improve Nexus 5 Battery Life

/ 3 years ago


According to latest news, Qualcomm has revealed that the new Google Nexus 5 not only features the company’s fastest mobile processor, the Snapdragon 800 SoC, but also features a certain Qualcomm QFE1100 envelope tracking chipset, which is a front-end for OEMs to design global 4G LTE compatible devices, like the Nexus 5. This isn’t the first time that the QFE1100 is being used in a Smartphone. Samsung was first to the finish line with the Galaxy Note 3, launched nearly two months ago.

“The Nexus 5 also utilizes the Qualcomm QFE1100 feature, an important component of the upcoming Qualcomm RF360™ Front End, a comprehensive, system-level solution that allows OEMs to develop a single, global 4G LTE design.”


Qualcomm states that the new chipset offers 30% lesser heat and 20% decreased power consumption. Thanks to the improvements made by the chip designer, the Nexus 5 will last longer while being used over 3G/4G networks than any other device with a similar battery capacity and internal specifications.

“The QFE1100 feature is the world’s first envelope tracking (ET) technology for 3G/4G LTE devices and offers significant performance improvements, including reduced heat by up to 30%t and decreased power consumption by up to 20%, enabling thinner form factors with longer battery life.”
