In 2014, OPPO launched vooc flash charge, the power reached 25W, advertised charging for five minutes, two hours of call, the release of this technology, let the market began to shock, after all, voOC flash charge did solve the problem of slow charging of mobile phones. Subsequently, in 2017, Meizu announced the 55W fast charging PPT, which further surprised the world, and since then, the fast charging technology has begun to rapidly popularize in the mobile phone circle.
As of January 30, 2022, the maximum charging power of the mobile phone industry reached 120W, including Xiaomi 10 Extreme Commemorative Edition, Xiaomi 12 Pro, Xiaomi MIX 4, iQOO 5 Pro, iQOO 9 and other models, they are fully charged between 15-25 minutes, compared to the 65W dual-cell mainstream half-hour charging speed, it has not achieved a particularly large breakthrough, including a brand of 80W, 100W, full also need 30 minutes.
From the end of 2021, there has been news that in 2022 there will be a more powerful flash charge launch, the recent data on the 165W super fast charge was officially exposed, it takes 10 minutes to fill the 4500mah battery in the laboratory, and after mass production, for safety considerations, the fully charged time still takes 13 minutes, compared with the 15 minutes required for the fastest 120W fast charge now, the full charge time is only increased by 2 minutes.
Although the improved charging time is only 2 minutes, there are many things to sacrifice for consumers. First of all, in terms of safety, the greater the charging power, the higher the heat, and the current will be greater, although the safety of the product produced can certainly reach the standard, but compared to the lower power of the mobile phone, the possibility of security problems in 165W fast charging is definitely greater.
Then there is the clichéd problem of battery energy density, the higher the charging power, the lower the energy density of the battery, the energy density of the 100W fast charge compared to the 30W fast charge battery energy density is reduced by 20%, and the energy density of the 165W fast charge compared to the 100W fast charge battery will be further reduced. At present, the internal space of the mobile phone is limited, and the low battery energy density means that while maintaining the battery capacity, it will inevitably increase the volume, resulting in the mobile phone being extremely thick.
In addition, it is a matter of cost, in order to increase the charging power of two minutes, it is necessary to share a large number of material costs and research and development costs, which is obviously a very uneconomical thing for consumers. From the above we can see that at this point in time, the composition of the 165W fast charging gimmick is larger, and even does not rule out that it is only the overclocked version of the current high-power fast charging, which has no practical use for consumers. Of course, it may also be a breakthrough technology, but this possibility is really unlikely for now.
