Tag: QC 5

Qualcomm recently unveiled its next-generation fast charging technology, Quick Charge 5+, boasting a faster and cooler charging experience with up to 140W of power. Compared to the previous Quick Charge 5, which supported 100W charging, the updated Quick Charge 5+ maintains the ability to charge a device from 0% to 50% in 5 minutes, supporting up to 20V/7A for 140W charging. It also incorporates more advanced temperature control and intelligent power distribution technologies, aiming for a better balance between charging efficiency and safety. Qualcomm explains that the Quick Charge 5+ design utilizes a low-voltage, high-current approach to reduce heat generation during charging and prevent devices from overheating, allowing for faster charging and stable performance output. By adjusting voltage and current in real-time, Quick Charge 5+ dynamically adjusts power output based on device usage, ensuring stable performance during work, gaming, and streaming, and reducing thermal stress on the battery during prolonged charging, thus extending battery life. Beyond speed and temperature optimization, Quick Charge 5+ technology also incorporates "intelligent power allocation," which identifies the type of connected device and automatically allocates power between the system and battery to ensure that charging does not affect the device's operating experience. On the other hand, the low-voltage strategy can reduce accessory costs by approximately $2 on average, making high-power charging solutions more readily available for a wider range of devices. In terms of compatibility, Quick Charge 5+ is backward compatible with Quick Charge 2.0, 3.0, 3.0+, 4, 4+, and 5, and is also compatible with the USB PD charging standard, providing an equivalent fast charging experience on non-Snapdragon computing platform devices, eliminating concerns about accessory compatibility. Qualcomm plans to unveil the first wave of devices supporting Quick Charge 5+ at the Snapdragon Summit in 2025, coupled with the accessory ecosystem launching at the end of the year, allowing users to complete daily charging faster, cooler, and more stably.

With mobile phone manufacturers including Xiaomi, OPPO, and vivo announcing the launch of fast charging technologies with charging power exceeding 100W, Qualcomm, which has previously proposed several QC fast charging technologies, recently announced its Quick Charge 5 (QC 5) fast charging technology, which supports charging power of over 100W. According to Qualcomm, Quick Charge 5 is the first commercially available design solution with charging power exceeding 100W, offering up to 70% improvement over the previously released Quick Charge 4 technology. For a 4500mAh battery, it can charge to approximately 50% in about 5 minutes. In terms of details, Quick Charge 5 is still compatible with the previously released Quick Charge 4+, Quick Charge 4, Quick Charge 3, and the earlier Quick Charge 2 specifications, and is also compatible with the USB-PD design protocol proposed by the USB-IF. With 12 voltage, current, and temperature protection mechanisms, Qualcomm emphasizes that Quick Charge 5 technology generates heat during charging, approximately 10 degrees Celsius less than its predecessor, Quick Charge 4. It also supports USB input overvoltage protection and external input voltage control. Furthermore, through Qualcomm's charging power identification technology, it ensures charging safety at maximum power conversion efficiency and potentially extends battery life. Qualcomm expects Quick Charge 5 technology to be implemented in commercially available products in the third quarter of this year, and it will be compatible with products using Snapdragon 865 and higher processors. Xiaomi, which has a deep partnership with Qualcomm, is confirmed to adopt this charging technology in its products.
