Fortunately, this unfortunate 2020 has ended but it has led to Xiaomi many satisfactions. Until the end, the brand held out and its efforts paid off. But not only the company's coffers are repaid, but also the developers. As usual, in fact, a ceremony was held for the "Million Dollar Technology Award“, Or the event aimed at rewarding the best technologies of the past year. For the first time they were given two first prizes to two particular teams which have just won a million dollars (yuan of course). Let's see what they are.
These are the two Xiaomi technologies that have won the Million Dollar Technology Award 2020: 120W charging and privacy protection of MIUI
Based on what the company itself said this morning, Durante it second event held by the company's foundation, a total of four awards were given for Xiaomi's best technologies of 2020. Naturally, the team of developers who contributed to improve MIUI and the technology on board our devices. For the first time in two years, however, two first prizes were awarded. The technologies in question are the 120W wired charging for smartphones and the most advanced feature of the MIUI 12 in terms of privacy protection. Curious to see how one regards the hardware side and one the software side.
120W wired charging
Xiaomi Mi 10 Ultra first adopted the 120W ultra fast charging and it was the first with this technology to be mass-produced. Thanks to the research of the development team, the device with 4500 mAh battery is able to recharge to 100% in just 23 minutes. The new high-efficiency charging architecture 4: 2 it allows the current to enter with a high voltage and to be divided not only by reduce its impedance but also to improve the overall conversion efficiency. To understand what we are saying, just look at the image below (from left to right). A custom chip is integrated into the charge pump Qualcomm .
Important feature of these technologies is the Battery Sense monitoring: this type of monitoring made possible by the Qualcomm chip allows the voltage not to reach maximum power for too long. In fact, we know that 120W are not continuous, but they are only the maximum peak reached by charging. Combined with this there are 34 levels of protection and security which allow automatic shutdown due to a technology anomaly.
Privacy on MIUI 12
In 2020 the brand released two versions of the custom skin: MIUI 12 e MIUI 12.5. The improvement in security features has been widely recognized by users and national institutions. Data protection has been at the center of attention since last September when the company presented MIUI 12. Although there have been some minor road accidents, it seems that the situation has stabilized.
As we know the brand has independently developed the MACE framework (Mobile AI Compute Engine), or an AI framework built specifically for mobile terminals. Thanks to it all data that is processed by our device is not sent to the cloud, but on site, i.e. offline on the terminal itself. In addition to this, Xiaomi has provided the so-called "Differential privacy“, That is a protection algorithm that is simple as an idea but very effective. This algorithm will include "interference "when the data will be uploaded, so that no attacker can get hold of it.
That said, these two technologies have won $ 1 million each while the second and third place they fell to the teams that were behind the projects MIUI, IoT and photography. They receive a bonus of $ 300.000 and $ 200.000 respectively.
