320W fast charging? My true self is going to break through the sky!

Needless to say, fast charging is really an eternal topic in the mobile phone industry.



Looking back at the biggest upgrade point of Android phones in recent years, in addition to screen refresh rate, processor performance and camera pixels, it must be the soaring charging rate.


From 18W in the early days to 65W in previous years, to today’s high-power fast charging of more than 100W. In just a few years, we have shortened the charging time from one hour to more than ten minutes, which made Xiao Lei think that we could really charge it thoroughly and say goodbye to the long wait.


However, after entering 2024, mobile phone manufacturers have never launched products with ultra-high charging power, let alone 200W, 150W are very few, and they are sold for six or seven times. The thousand-yuan flagship phone only comes with a charging power of about 90W as standard.


This also makes people wonder: "Could it be that the super fast charge has ended like this?"


Fortunately, I really didn't think so.

On August 14th, Realme held a new fast charging technology communication meeting at Shenzhen Excellence Houhai Center to introduce to us the brand’s mobile phone charging technology The latest breakthrough.


Just like the warm-up before, the world's first 320W fast charge became the focus of this communication meeting. Xiaolei naturally rushed to the scene, ready to personally experience the latest achievements of Realme's flash charging technology. By the way Look at the paper data that is almost three times that of the common 100-watt fast charge on the market. How can the already convenient blood recharge experience be raised to a new level?


Based on technology, it only takes 4 minutes to fully charge



To kick off the 828 True Fan Festival, the first person to speak on stage was Xu Qi, Vice President of Realme and President of China.


We briefly introduced the achievements of the Realme GT6. It has been ranked first on the JD.com Snapdragon 8 Gen3 mobile phone best-selling list for seven consecutive days, which is enough to prove that the phone is very popular online and is worthy of its peers. A highly sought-after performer.

As for the after-sales aspect that Zhen fans are most concerned about, Kaizi also emphasized the future construction plan. By the end of 2024, Zhenwo will expand offline service outlets to 500 Home, covering 80% of university towns across the country, and will provide users with worry-free backup machine services.

When it comes to the technical part, it is customary for Fu Qi, the person in charge of Zhenwo’s technical planning, to give the lecture.


First of all, we will introduce some new breakthroughs in technology of Realme, such as AI game super score. This is the first AI game super score technology in the industry that uses the end-side AI model to increase the resolution in real time. It can use NPU super score band for a clearer visual experience.

As for the effect, I personally think it is much better than simple sharpening.


There is also the industry's first solid-state button that supports sliding and pressing. In actual testing, it can slide to zoom and press the shutter while taking pictures, bringing a camera-like silky touch. The press-to-photo shooting experience is indeed good, but the speed of sliding and zooming is a bit slow. Slow, I hope it can give users some room for adjustment during future implementation.

In addition, there is also a self-developed anti-reflective film that can significantly reduce the reflectivity of the screen, providing clear visual effects in bright external environments; it can adjust sound positioning holographic audio technology, and AI Tusheng video technology that can convert a single image into a dynamic 25-frame video.


The release of these technologies further demonstrates Realme’s strength and determination in innovation.


Of course, what everyone at the scene is most concerned about is definitely the unprecedented 320W super-light speed charging technology.

In order to achieve 320W fast charging, Zhenme, who has long been exploring the field of flash charging technology, has made a trade-off between "high power, high security and miniaturization". It has successfully brought about a breakthrough in power and achieved a balance among the three through technological innovation.


First of all, it is a breakthrough in battery technology. By cutting a battery into four cells, and using flexible circuit boards and high-density stacking technology, we successfully folded the four cells and put them inside the mobile phone, bringing it to the world. The first foldable smartphone battery.

折りたたみ式バッテリーの各セルは、厚さわずか 2.9 mm ですが、容量が従来のデザインより 10% 増加し、バッテリー容量が向上します。同時に、バッテリーの安定性と安全性も確保します。


次に、充電の安全性の保証があります。フラッシュ充電の分野のパイオニアとして、Realme は今回、高電力密度の磁気結合 DCX 降圧技術である「空中電力伝送」を開始しました。回路に重大な障害が発生した場合でも、電圧はバッテリーから絶縁され、これまでに市販されているアダプター、インターフェース、過負荷保護、バッテリーヒューズ保護などの多くの安全保護手段と組み合わせて、高電圧充電を保証します。急速充電の安全上のリスクを効果的に回避できます。

最も重要な充電器、今回 Realme は、Realme 240W 充電器と同じサイズで、電力密度 3.3W/ の 320W デュアルポート窒化ガリウム充電器を発売しました。立方センチメートルでコンパクトで持ち運びが可能で、UFCS (最大 320W)、SuperVOOC、PD、PPS、その他のプロトコルを含む、市場の主流の高速充電プ​​ロトコルと互換性があります。

これはライブデモンストレーションであり、Apple の 140W 窒化ガリウム充電器よりも本当に小さいです。

非常に多くのテクノロジーを使用した 320W フラッシュ テストのパフォーマンスについては...


一言で言えば、素晴らしいです。


サイトに展示されているrealmeテスト機は1分で28%、2分で53%充電可能で、その後の繰り返しテストでは4分58秒でフル充電できることが測定されました。 、4分23秒のレベルも達成可能です。

4420mAhバッテリー、4分で完全に健康になります...


本物の赤い角が3倍早く来ているとしか言えません。


しかし、誰もが最も懸念しているのは、いつ量産可能になるかという問題です。ドライバーは現場で不注意で、具体的な製品計画を与えませんでした。

テクノロジーの実装はそれほど簡単ではないとしか言​​えません。


バッテリー寿命または急速充電が必要ですか?



携帯電話の急速充電技術の変化という点では、Realme は実際に業界をリードしてきました。


Realme GT Neo3 は、2022 年にはすでに世界初の 150W 光速 2 番目の充電テクノロジーを導入しています。 Realme GT Neo5は2023年に240Wのフルレベルの2回目の充電で世界で量産開始され、公式は「9分でフル充電できる」と主張しています。

さらに詳しく言えば、Xiaomi の Redmi ブランドは実際に 300W 充電技術を実証しましたが、これも Realme のように実験室レベルにとどまった技術実証であり、実際には発表されていません。多くのメーカーが急速充電技術を公然と披露しています。


つまり、最近の私はパワーチャージがとても上手なんです。


しかし、多くの主流メーカーが100W急速充電の提供を中止したのには、実は理由があります。現在の市場技術では、充電電力が増加するにつれて、本体スペースと発熱という二重の制限と相まって、バッテリーのエネルギー密度が必然的に影響を受けるため、急速充電とバッテリー容量はシーソーの両端のようなものです。矛盾した関係：一方の端が高ければ、もう一方の端は下がります。


メーカーがしなければならないことは、急速充電電力とバッテリー容量の間のユーザーエクスペリエンスのバランスを見つけることです。


例えば、Realme GT Neo5は、リリース時に「4600mAh+240W」と「5240mAh+150W」の2つのバージョンを提供しました。RedmiやRed Devil もすべて、さまざまなユーザーのニーズを満たすために、同様のデュアル構成の製品設計を採用しています。

主力製品に関しては、プロモーションの焦点は一般的にバッテリーにあります。昨年末以来、「金沙江」と「青海湖」を筆頭に、100ワットの急速充電を維持しながらバッテリーのエネルギー密度を高めることができる新しいバッテリー技術が多数市場に登場しました。携帯電話のバッテリー寿命を延ばしません。


In other words, 320W fast charging is definitely worth looking forward to, but how can we organically adjust the three almost mutually exclusive factors of large battery, high-power fast charging and thin and light body to ensure the implementation of fast charging technology? At the same time, inserting a larger-capacity battery will be a greater attraction of this future mass-produced machine.


Looking back, charge pumps, dual cells, gallium nitride... the progress in charging technology is actually no smaller than that of other parts of mobile phones. It can even be said that a revolution has been completed quietly.


Nowadays, even a simple brushing of teeth and face, a light meal or even a game can fully charge a large-capacity battery, greatly alleviating the battery life anxiety caused by intensive use of mobile phones, and every ordinary person can Enjoy technological advancements.

From the current point of view, Realme is indeed relatively far ahead in the industry, but judging from the actual products, other manufacturers may also achieve similar results within a few months. experience, eventually the entire industry will return to the same starting line.


At that time, how to continuously, stably and equally provide mobile phone fast charging to the public will become a new topic that constitutes the competitiveness of each brand's product line.


As for the charging time after entering within five minutes, can wired charging of mobile phones be faster? After the restrictions are lifted, how can higher-end wireless charging bring changes beyond just speed? We can just wait and see for more good shows to come.
