In recent years, manufacturers have already developed fast charging technology to a level that most customers can be satisfied with, but the operating time has not improved significantly. In Xiaomi's R&D center, specialists are said to be working on this as well, and a significant improvement can be expected.
Today, a typical smartphone has a 5,000mAh battery, which can be charged at 80-120W. According to leaked information, Xiaomi has set a goal of increasing the battery capacity by one and a half times, while retaining fast charging. At the R&D center in Nanjing, the company is working to achieve higher and higher capacity by developing battery technology.
The company wants to move forward gradually, and in the future it will be possible for batteries with a capacity of 6000-6500 mAh to gain space, while maintaining a charging power of 120-100 watts. Larger batteries can always be charged with slightly lower performance, and this is what the Chinese developers are counting on.
There is currently only one such configuration among conventional mobile phones, namely the OnePlus Ace 3 Pro. This smartphone, announced at the end of June, has a 6,100 mAh battery and supports fast charging with a power of about 100 W. In this case, in principle, a full charge from a discharged state takes 36 minutes. Oppo has always been among the best in the development of battery and fast charging technologies, so it is not surprising that it already has a commercially available configuration that Xiaomi wants to achieve in the next generation.
The really important thing won't be the change when 6000-6500mAh batteries start to become widespread, of course this will also bring some improvement in operating time. But Xiaomi's goal of packing 7000-7500mAh batteries into mobile phones promises to be more interesting. And even then the company will maintain 120-100W fast charging. Increasing capacity and maintaining fast charging is particularly difficult, but you have to see that it is necessary to maintain the experience.
According to the leaked information, Xiaomi's calculations indicate that a smartphone with a 7,000mAh battery will take about 40 minutes to fully charge from a discharged state to 100 percent when charged at 120W. On the other hand, a 7,500mAh battery takes just over an hour to charge at 100W. So, at this level, the implementation of such a powerful charge is fully justified.
It is not possible to know in detail what exactly Xiaomi is preparing for the innovations, but it is likely that, for example, the application of silicon carbide will also appear. Honor has already made a splash with it in the case of foldable smartphones, and batteries using SiC technology have already appeared in BBK Electronics brands. In addition, there may be other developments in terms of battery chemistry.
Rumors did not mention when Xiaomi could come up with innovations. We hope that other manufacturers will start moving in this direction, and in the coming years, mobile phones equipped with slightly larger batteries than usual, which users have been waiting for so long, will indeed come.
