From the function machine that smashed everything in the past to the smart phone that connects everything now, the performance of mobile phone is more and more powerful, and the degree of customization is higher and higher. Even the output power of the processor can be adjusted manually. In addition, the addition of high refresh rate, 5g, large pixel and large bottom lens makes the mobile phone more multifunctional and easy to use. But there’s one thing that doesn’t seem to be a significant boost. Yes, it’s endurance. < / P > < p > if you’re using a mobile phone that has been released in the last two years, you should feel something about this. Although judging from the parameters, the battery capacity of the mobile phone has improved significantly compared with that in the past. 4000mAh batteries have become the starting point of battery capacity, which was only possible for top flagship in the past. However, the battery life did not seem to be significantly enhanced, and even four hours became a common occurrence. < / P > < p > in this regard, the manufacturer has provided a solution — super fast charging, 100 watt fast charging. In July this year, oppo, iqoo, Xiaomi, realme and other brands have launched their own 100 watt fast charging solutions. For example, oppo has not only come up with 125w super flash charging technology, but also launched a number of charging devices that support multiple charging protocols. However, some users didn’t buy it and said, “shouldn’t the simplest way be to increase the battery?” As a non famous editor, I just want to say that In fact, I think so. But for manufacturers, can they say that consumers are wrong? This will, on the contrary, provoke discontent. As the saying goes, “history is a circle,” Henry Carter, founder of Ford, once asked consumers, “what kind of transportation do you need?” “A faster horse,” the respondents said In the end, Ford built a car. < / P > < p > I also think a lot about this issue, so I put forward a “fulcrum” here – not that the batteries are not enough, but they are used in other places. < / P > < p > I can draw this conclusion, which is directly related to my actual experience. In March of this year, I had the honor to experience a top Android flagship, with high refresh rate of 120Hz, high-tech snapdragon 865, 2K screen, 65W fast charging Oh, it’s hard to talk with colleagues when I go out. I’m more willing to discuss mobile phone topics with people. < / P > < p > at this moment, the inside and outside of the store are full of happy atmosphere, which is really amazing. However, with the depth of use, it is found that the endurance is not very good. I like to use 2K + 120Hz screen parameter combination, but relatively, it is a very big test for the endurance, especially the power consumption caused by high resolution. On August 1, I was ordered to go to Shanghai on business. I watched cosplay, performances, handmade and miss (this one is not) I took a few photos along the way and tasted them by myself. But I didn’t use it for an hour, and the power was 70%. If I took a few more videos, the power would be less than 50%. Someone asked, “why don’t you fill it up?” I was in an environment where there was no place for charging. To be honest, I was a little flustered and the venue was getting hotter. < / P > < p > after a bit of groping, I finally found a socket in a cafe. There is a saying that at this time, the advantage of fast charging is shown. After charging for less than half an hour, the battery power of the mobile phone becomes very “safe”. Well, I’m glad. Thanks to the existence of fast charging, mobile phones can quickly re-enter the battle. But in the afternoon, the situation happened again, and my brain was boiling with the continuous decline of electricity. I can’t help but shout: “why do you treat me like this Say, countless people look at me < / P > < p > the next day, I had a brainstorm and turned off some functions that I couldn’t use temporarily, such as 2K resolution, HDR video, display brightness, etc., and only kept 120Hz, because the high refresh rate is really enjoyable. Sure enough, when the function is turned off, the power consumption will be reduced, and the super long endurance will occupy the high ground again. < / P > < p > I will encounter such embarrassment, which is related to my usage habits to a certain extent. On the one hand, I like the freshness brought about by new functions. On the other hand, I can accept charging once a week in the era of functional machines. Now it is not difficult to accept the charging of more functional smart phones every day. < / P > < p > but it is undeniable that with the development of technology and the increase of function points, the battery of mobile phone must pay more than before. In 2020, higher resolution, higher refresh rate, faster network speed, stronger performance and a series of new technologies will bring consumers a solid and high-quality user experience, but they will also compress the service life of mobile phones. Furthermore, in order to support these function points, manufacturers have to place more components in the limited fuselage of mobile phones, such as cameras with large pixels and big bottoms, periscope modules, dual speakers, etc., so as to objectively reduce the possibility of placing large batteries. This is very obvious on the current flagship mobile phones, but relatively, I also enjoy the benefits of these hardware and features, especially the periscope long focus camera. I really love it. < / P > < p > from another angle, if we start from the battery itself, it is easy to think of an old saying that battery technology has not improved. Strictly speaking, this is not all true. Even limited by the size of mobile phones, the energy density of lithium batteries has improved in recent years, which is why ultra-thin 5g mobile phones can accommodate at least 4000mAh batteries, such as Huawei Nova 7 Pro, oppo Reno 4 pro, glory 30 pro, etc. < / P > < p > if we want to see the breakthrough development of lithium battery, or battery technology, and bring more capacity in the same volume, we must make obvious progress and breakthrough in basic disciplines and theories such as materials, chemistry, physics, and so on. The top-level application development will be driven by the basic disciplines. It is expected that the battery will have a different appearance at that time. At the same time, most of the mobile phone processor chips adopt advanced process technology such as 7Nm, which brings about a stronger energy efficiency ratio and extends the life of the mobile phone to a certain extent. < / P > < p > in conclusion, unless the battery technology adapts to the progress of hardware or surpasses the development speed of the latter, the battery life of our smart phones will make significant progress, but relatively, the service life is relatively good Upgrade provides a good space for hardware development. Therefore, I think that the coordinated development of the two is undoubtedly the most appropriate. But from now on, it’s a bit idealistic. < / P > < p > from 5W, 10W, 18W, 22.5w to 40W, 65W, and now 125w, the charging time is from 2 hours before to the fastest 15 minutes to complete 4000mAh battery charging. With the development and popularization of fast charging technology, we will be more and more indifferent to charging, just as I used that mobile phone for the first time. < / P > < p > in July, I purchased oppo find x2 pro at my own expense. In addition to the amazing screen, the 65W ultra fast flash charging of this mobile phone may be more in line with the pace of my life now. Although the MAH battery is a little small in my normal residence, company and shopping mall, it is enough for me to use. When I get home, I habitually plug in the power supply and charge it. It can be fully charged in about half an hour, and then it is a pleasant time to play. Of course, everyone has bad luck. On the evening of July 26, I was slightly drunk, more or less conscious. As a result, I forgot to charge my mobile phone. The time in the morning was tight. What should I do? There is a saying that at this time, the benefits of high-power charging are highlighted. 4260mah Battery + 65W super flash charging can charge about half of the power in 15 minutes, which is enough for commuting on the road. As for how the power consumption on the road depends on your usage. < / P > < p > just like taking photos of flagship mobile phones, the benefits of fast charging can be seen, which is called “strong perception”. Generally speaking, the situation of “fully charging after the battery is used up” is more likely to occur in extreme situations, because according to the current usage habits, 20% of the power is almost “the limit of human endurance”. How can it be Allow your mobile phone to run out of power? After all, mobile phones play an important role in social networking, payment, games and communication. < / P > < p > assuming that the charge starts from 0% to 100%, oppo find x2 Pro can be fully charged in about 40 minutes. If the battery is charged at 125w, a 4000mAh battery can be charged from 0% to 41% in 5 minutes. What can you do in five minutes? Make a cup of coffee? Take a call? Fish at work? In addition, for the scene with tight time in the morning, sometimes it needs not to be fully filled. What’s the maximum charge? < / P > < p > in my opinion, this is one of the significance of the existence of 100 watt fast charging solutions such as 125w. Like wireless charging, you can use your fragmented time to charge your mobile phone, which can not only be used for emergency, but also a kind of preparation. If you think about it, you can do more things with your mobile phone, such as doing things you love. < / P > < p > but there is one point. When we experience that from 2 hours to 40 minutes, and then to about 15 minutes, it will be shortened to 10 minutes, 5 minutes, or even shorter in the future. At that time, can super fast charging bring us such a big surprise today? < / P > < p > in July this year, I saw the application of fast charging technology. It is only a matter of time before commercial use. Moreover, there are already 100 watt fast charging mobile phones on the market. < / P > < p > but when we are glad to have a stronger fast charging technology applied to mobile phones, we should also pay attention to the battery life of the mobile phones. As I have encountered in the meeting hall, in the face of scenarios that cannot be charged, we rely more on our own endurance ability, or we can increase the load, bring the power bank or charging clip and other products. < / P > < p > but on the other hand, for manufacturers, they can fully highlight mobile phone products with large batteries and long endurance, but make compromises in the aspects of screen, photo taking, performance, etc., but this may sacrifice the user experience of consumers, such as clearer photos, stronger performance, etc. < / P > < p > therefore, when you plan to buy a new phone, the endurance must be taken into account. Even if you are in a rechargeable place every day, sometimes the battery capacity can not fully represent the life of the mobile phone, but with a large battery, the battery life will not be too bad. As for fast charging, the changes brought about by fast charging are very obvious, especially in flagship phones and medium and high-end mobile phones. A 4000 MAH mobile phone can be filled in about 15 minutes. Isn’t it fragrant? From a large perspective, the advent of electricity has greatly promoted the development of social productivity and the completion of the second industrial revolution. Nowadays, electricity has been integrated into all aspects of life, including the compact type-C interface. It all happens before you know it, and the advent of new charging technologies will deepen that change and shine in the next technological revolution.
