Is Xiaomi’s 120W Hypercharger technology safe?
Xiaomi first launched the Xiaomi 11T Pro in Europe in September 2021, 120W super fast charging technology He introduced himself. This technology was then introduced in the Xiaomi 11i Hypercharge phone, which was recently made available to buyers in India. According to the company, the 4500 mAh battery of the 11i Hypercharge can go from zero to 100% in ideal conditions in 15 minutes. Although 120W super fast charging is considered a breakthrough technology in the smartphone industry, the question is whether this technology is safe or not.
Website Digital Trends has researched how the hypercharge technology works to see what measures Xiaomi has taken to keep users safe.
The working method of Xiaomi’s 120-watt ultra-fast charging technology called Hypercharge
Xiaomi has announced that Hypercharge fast charging technology by combining new innovations in battery and charging circuit and charger is enabled. Let’s talk a little about the technical issues of this technology and its important technologies. Hypercharge consists of five distinct parts:
- Dual charge pumps
- Dual cell batteries
- Multiple winding technology (MTW)
- Graphene-based battery
Xiaomi first modified its entire charging structure and used dual charge pumps to better control the voltage and current of dual-cell batteries. benefited This means that there is more wattage, which will reduce the charging time. The Xiaomi 11i Hypercharge uses a two-cell battery, which is used to increase the available input power compared to the standard single-cell battery. This feature also helps to reduce the charging time.
The said company has also used the Multilingual Winding (MTW) technology, which provides the possibility of establishing a better current in the battery. By using multiple anode and cathode tabs instead of the traditional one or two current paths that have higher current resistance, the energy flow paths will be shortened. By constructing multiple tabs, MTW reduces resistance and helps increase flow speed.
However, there is an important obstacle in between. If you have ever used fast chargers, you must know that the charging speed decreases significantly after the battery capacity reaches 85%. To avoid this problem, Xiaomi has used Mi-FC technology. This technology allows the current to be transferred from the charger to the battery for a longer period of time. To control all these components, Xiaomi has used the current and cell voltage monitoring system in real time. Since more current continues even after charging 85% of the battery capacity, Xiaomi’s control system will reduce the charging time from 85% to 100%. This company has finally used graphene-based battery technology. These batteries have higher conductivity than traditional batteries, which makes them charge faster.
A combination of modified charging structure, dual-cell battery, Mi-FC, MTW and graphene-based battery technology allows Xiaomi to charge the battery of devices charge itself faster.
Is Xiaomi’s 120W hypercharger technology safe?
Xiaomi has said that it has not only spent its time improving the charging time; It has also paid attention to ensuring the safety and efficiency of this technology. 120W super fast charging technology in Xiaomi phones comes with 34 protection features. Among these protective features, we can mention safety measures from charger, circuit to battery for long-term operation. These features are:
- Charge and discharge protection at high battery temperature
- Protection against circuit overheating
- Protection of excess current of USB input in Circuit
- Short circuit protection for charger and circuit
- Overcurrent protection and overvoltage protection for Xiaomi charger
Xiaomi has used 9 instant thermal monitoring sensors to compensate for the high current and not to heat up the phone abnormally. . In addition, the company’s technology has received TÜV Rheinland’s Safe Fast Charging System certification. This certificate is usually given to smartphones, power banks, laptops and other devices to confirm the safety of their fast charging system after passing some tests.
According to Xiaomi, the 11i Hypercharge maintains up to 80% battery health after 800 charge and discharge cycles. . This figure is less than the 1,000 charge cycles that a device in Psafe’s study could withstand before losing 20% capacity. However, ResearchGate’s study shows that battery health drops to less than 80 percent between 500 and 1,000 charge cycles; Therefore, Xiaomi’s claim is within this range. For this reason, you should not worry about the battery capacity and its rapid exhaustion.
Does Xiaomi 11i Hypercharge really in 15 minutes from zero to 100% Does it charge?
The short answer to the above question is no. With the tests done on the Xiaomi 11i Hypercharge phone, the device did not charge from zero to hundred in 15 minutes, and besides, no one uses their phone under ideal conditions. Xiaomi’s 120W fast charging technology is not enabled by default, and to use it, you need to enable the Boost power output option in the battery settings section so that the device can be charged with a maximum power of 120W. Next, you can see the statistics obtained when the Boost option is active:
- 10% charge in one minute
- 31% charge in four minutes
- 59 Charging percentage in 7 minutes and 10 seconds
- 100% charging in 16 minutes and 42 seconds, which will take about 27 seconds to reach the last 1%
