In the era of excess performance of mobile phones, the battery technology of mobile phones has not been greatly improved, and the battery capacity and battery life have become a major bottleneck for the improvement of smart phone performance. In the case that the battery technology cannot be upgraded in a short time, many mobile phone manufacturers use rapid charging as a breakthrough to improve the charging efficiency and alleviate the problem of insufficient battery capacity.
On September 15, Qualcomm launched its latest QuickCharge 3.0 fast charging technology in Hong Kong. Compared with the previous generation, QuickCharge 3.0 The smart voltage collaboration algorithm is adopted for the first time, which has more than doubled the charging time of the same platform, and reduced the power loss by 45%. An ordinary smart phone charges from zero to 80%. The second generation technology takes 90 minutes, and the third generation technology only takes 35 minutes. The improvement of charging efficiency can also extend the service life of the battery, and the charging speed is increased by twice. According to the details published on Qualcomm's official website, the so-called best voltage negotiation only technology is a new algorithm developed by Qualcomm Technologies, which aims to help portable devices have the ability to select the required power level, so as to achieve the best power transmission at any time and maximize efficiency. On this basis, QuickCharge 3.0 can provide a flexible choice of voltage from 3.6V to 20V in 200mV increments, which will allow the phone to obtain the right voltage and achieve the expected charging current, thus minimizing power loss, improving charging efficiency and improving thermal performance.
Qualcomm Snapdragon 430 and Snapdragon 617 were also a highlight of yesterday's launch. They also support Qualcomm's new QuickCharge 3.0 fast charging technology. Both are upgraded in baseband function.
Snapdragon 430 adopts X6 LTE modem, supports Cat 4 for downlink, the maximum transmission speed is 150 Mbps, and supports 2x10 MHz carrier aggregation; In addition, by supporting 64-QAM in this level of processors for the first time, the uplink supports Cat 5, with a maximum transmission speed of 75 Mbps. On the graphics processor, Qualcomm Snapdragon 430 is equipped with Adreno 505 GPU, which supports Open GL ES3.1, Android Extension Pack, OpenCL 2.0 and other features. Qualcomm Snapdragon 617 includes features previously limited to high-end products, which is more comprehensive than Snapdragon 430's connectivity and capabilities. In order to meet the global demand for faster LTE data rates, Snapdragon 617 integrates X8 LTE modems, supports Cat 7 with two-way 2x20 MHz carrier aggregation, with downlink speeds up to 300 Mbps and uplink speeds up to 100 Mbps. In addition, Qualcomm Snapdragon 617 and Snapdragon 620 and 618 share the same software upgrade, dual ISP and camera architecture.
In terms of core configuration, Snapdragon 617 and 430 processors both use high-performance ARM ® Cortex-A53 eight core CPU configuration, both processors use high-performance, low-power Qualcomm Hexagon DSP, which supports low-power sensors and advanced audio functions. The introduction of these two processors complements Qualcomm's position in the mid tier product line in 2016. This faster and more efficient chipset is undoubtedly what major OEMs want to see.
With the official release of Snapdragon 430 and Snapdragon 617, the connectivity related parameters of Snapdragon 820 have also been officially exposed. Snapdragon 820 will be equipped with the new X12 LTE modem for the first time. This makes it the first SOC chip in the industry to publicly announce its support for downlink LTE CAT12 and uplink CAT13. The downlink supports up to 600Mbps and 4 * 4 MIMO, and the uplink supports up to 150Mbps. In terms of Wi Fi connection, it supports 2 * 2 MU-MIMO (802.11ac) and multi gigabit 802.11ad standard. WiFi/LTE antenna sharing technology is adopted to realize the call continuity of Wi Fi, LTE, 3G and 2G networks. The terminal equipped with Snapdragon 820 processor is expected to be officially launched in the first half of 2016.
The popularity of Qualcomm's QuickCharge 3.0 has eased a major bottleneck in the development of smart phones to some extent. Although there are not many Quick Charge 3.0 chargers available on the market, with the popularity of large batteries, Quick Charge 3.0 will soon be widely adopted by manufacturers. Moreover, because Quick Charge 3.0 supports Snapdragon 430, Snapdragon 617, Snapdragon 820 and other processors, almost all flagship models launched this year and last year will support 3.6V to 20V voltage. Users holding the previous generation of flagship models can also use Quick Charge 3.0 chargers with confidence to save valuable charging time. Qualcomm's next-generation processor, Snapdragon 820, publicizes its support for downlink LTE CAT12 and uplink CAT13. However, in China, China Mobile and China Telecom are still popularizing 4G+. At the level of CAT6, South Korea, which has the most developed telecommunications network, has only developed to CAT9. So we still have a long way to go.
