Nexus 5 comes with Qualcomm QFE1100 Envelope Tracking chip for 20% more battery life


Google released the Nexus 5 last week, that is coming soon to India. We already know that the phone is powered by the latest Snapdragon 800 chip from Qualcomm. The company has announced that Nexus 5 also features the Qualcomm QFE1100 Envelope Tracking chip, the innovative Qualcomm RF360 front-end that allows OEMs to develop a single, global 4G LTE design. The Samsung Galaxy Note 3 that was launched back in September was the first phone to use the world’s first envelope tracking (ET) technology for 3G/4G LTE devices.

Qualcomm says that this tech offers significant performance improvements, including reduced heat by up to 30 percent and decreased power consumption by up to 20 percent. The Nexus 5 packs a 2300 mAh battery, which is just a minor increase from the Nexus 4’s 2100 mAh battery. Even though the phone packs just a 2300 mAh battery, users can get a longer battery life when they are using it on 3G/LTE with this new feature.

The QFE1100 chip adjusts the PA power supply to track the envelope of the PA output signal level which results in a more reliable amplified signal with up to 20% improvement in PA power efficiency and up to 30% improvement in heat dissipation. Here is a infographic that details this feature.
