Various new technologies are emerging one after another, which surprises people. With the blessing of new technologies, mobile phones have also developed more possibilities and improved the performance of all aspects. So what surprises will we have in the new year? Let’s imagine 2023 together today.
High-quality sound quality, OPPO self-developed Bluetooth chip Mariana Y
At the OPPO Future Technology Conference in 2021, OPPO officially announced its first self-developed imaging chip Mariana X. The birth of this imaging chip raised OPPO’s imaging technology to a higher level.
At the Future Technology Conference last year, OPPO also officially announced its second self-developed chip Mariana Y. With the rapid development of mobile audio, product homogeneity, high-end user needs, and refined experience are constantly impacting major manufacturers, and it is time to “break the ice” in terms of audio. OPPO’s self-developed chip is a technical chip in Bluetooth audio.
The innovation of the Mariana Y chip in Bluetooth audio is first of all the transmission rate. Through the first ultra-high-speed Bluetooth solution, it integrates a 12Mbps Bluetooth rate that is 400% faster than traditional Bluetooth and is currently the fastest in the industry. In addition, OPPO’s customized R&D performance is leading The unique URLC lossless encoding realizes wireless transmission of 192KHz/24bit lossless audio for the first time.
This technical innovation of OPPO directly realizes the freedom of transmission of the “limited” lossless audio.
On the image, AI computing power has been widely used and the technology is very mature. OPPO’s Mariana X is an AI algorithm chip used on the image, which can make the image even better. However, the AI algorithm in the audio field has not been popularized, so OPPO’s self-developed chip Mariana Y has added the AI algorithm.
As the first Bluetooth audio SoC with integrated NPU unit, the computing power of Mariana Y’s high-performance NPU unit has reached an advanced 590 GOPS, but the integrated high-performance DSP computing power of Mariana Y is 25 GOPS, but it is also an industry One of the strongest DSP performance.
With its super computing power and advanced AI algorithm, Mariana Y has achieved good results in audio, and Mariana Y has also realized the sound separation technology on the audio side for the first time.
Based on the 6nm process technology, Mariana Y has further expanded to the world’s most advanced N6RF radio frequency chip process. This is the first time that OPPO has applied the world’s most advanced process, which also means that OPPO has mastered the ability to apply advanced processes to radio frequency systems.
The two self-developed chips have made OPPO take a big step forward in self-developed technology. The maturity of OPPO’s new technology will also bring performance breakthroughs on mobile phones and continue to surprise users.
Breakthrough in flash charging technology, realme supports 240W flash charging
Realme announced that it will hold a flash charging technology communication conference on January 5. The theme is “The Final Chapter of Mobile Flash Charging”. At the conference, realme’s new flash charging technology 240W fast flash charging will be introduced.
Domestic mobile phone brands have always been obsessed with flash charging technology. From 67W fast charging to today’s millions of fast charging, it can be said that the flash charging technology of mobile phones has become more and more perfect. The real 240W flash charging will reach the highest power of the Type-C3.1 protocol at this stage, which is a major technological breakthrough for mobile phones.
According to previous information, Realme GT Neo5 will be the first mobile phone equipped with this 240W flash charging technology. The standard version of Realme GT Neo5 supports 150W wired fast charging, while the high-end version of Realme GT Neo5 will support 240W wired fast charging.
Realme 240W super flash charging uses a universal USB-C charger with an output parameter of 24V10A, which is directly output to the dual-string battery pack by two charge pumps.
After entering the mobile phone, the power is converted into 10V/24A by the charge pump for high-voltage direct charging. The new generation of batteries supports higher rate charging, and the current of a single battery can reach 12A. With the blessing of 240W super flash charging, a mobile phone with an equivalent 4500mAh battery capacity can be charged to 100% in 9 minutes, and the charging time of the mobile phone has entered single digits for the first time.
Realme’s 240W fast charging technology is a comprehensive upgrade of the entire charging link. It has been upgraded on the adapter, wire and battery cells, which can ensure temperature control and safety during charging throughout the process, and can also reduce heat generation.
Realme mobile phones have always been mid-to-low-end models in China, just like the Realme GT Neo3 launched last year, which introduced 150W flash charging into the mid-range market. Many models have also begun to popularize 200W fast charging. It is believed that the continuous improvement of flash charging technology will reduce consumers’ charging anxiety.
3nm process, a new level of mobile phone chips
Earlier news said that the iPhone 15 will use the A17 chip, and the A17 chip will use TSMC’s 3nm process. Samsung also announced the production of the 3nm process in the first half of last year.
TSMC said that under the 3nm process, the power consumption will be reduced by 25%~30%, the performance can be improved by 10%~15%, and the transistor density will be increased by about 70%. The area of the SRAM cell of the N3 process is 0.0199 square microns, which is 5% smaller than that of the N5.
In terms of process selection, TSMC’s 3nm chip has chosen enhanced Fin FET technology, the SRAM density has increased by 20%, and the analog density has increased by 10%, and TSMC has started mass production.
It can be seen from TSMC’s 3nm process that this time the 3nm focuses on reducing the energy consumption of mobile phones and improving the battery life of mobile phones, but the improvement of mobile phone performance is not very high.
This can be said to be a strong blessing for e-sports mobile phones. It reduces the energy consumption of mobile phones and enhances battery life, and the heat and heat of mobile phones will be alleviated.
Every process upgrade represents an upgrade of mobile phone chips. Although the current news shows that only Apple is now using TSMC’s 3nm process, but with the continuous improvement of TSMC’s 3nm process technology, I believe that the two Android chip giants Qualcomm and MediaTek will also When it is added to the use of 3nm process technology, the chip of the mobile phone will usher in another upgrade at that time.
Variable refresh rate in different areas of the Samsung screen
Samsung’s display technology has always been at the forefront. The Samsung S20 is the first product to adopt a fixed refresh rate of 120Hz. The S21 Ultra and the subsequent S22 both use variable refresh rate screens. The variable refresh rate screen can be adjusted according to the display. Adjust the refresh rate of the content to achieve the ability to increase the battery life of the mobile phone.
Not long ago, Samsung applied for a new patent on the display, which can simultaneously apply display technologies with different refresh rates to multiple areas on a screen.
According to Samsung, this technology can “drive the display at multiple refresh rates” to allow the display to “drive multiple display areas at different drive frequencies.” That is to say, part of the screen can be presented at a refresh rate of 30Hz or 60Hz, while the other part is presented at a frequency of 120Hz.
The research and development purpose of this technology is to reduce power consumption and improve energy consumption ratio. The current flagship phones basically have a screen refresh rate of 120Hz. If the mobile phone is always in a high refresh rate of 120Hz, the power consumption will be very fast.
If a part is displayed at a lower refresh rate, and the other part of the screen that uses the most runs at 120Hz, it can not only increase the display capability, but also further optimize the battery life of the mobile phone.
If this technology can actually be put into use, it will be a good way to reduce the energy efficiency of mobile phones. However, this technology also has a big problem. There are more than a thousand popular and universal APPs in the world. It is too much work for Samsung to debug each software.
However, this patent was submitted in early 2021 and was only recently published. Perhaps Samsung has found a solution.
Summarize
In terms of new mobile phone technologies, mobile phone manufacturers are getting more and more involved. So far, the performance of mobile phones has been improved by chips with a 3nm process.
In terms of mobile phone accessories, OPPO’s self-developed Bluetooth chip Mariana Y, 240W flash charging technology, and Samsung’s variable refresh rate display technology in different areas have all pushed mobile phones in a more advanced direction. Let’s look forward to what new technologies will come in the future.
