high screen refreshing and fast charging can be said to be the standard equipment of current flagship phones, especially high-efficiency fast charging, which has become the gospel of heavy mobile phone users in the 5G era. However, the current fast charging technology shortens the charging time by increasing the charging power. Therefore, many users have questions about whether the fast charging of high-power mobile phones will damage the battery and whether the safety is guaranteed. Should I use high-power fast charging?
In response to this problem, the official WeChat account of "State Grid Jiangsu Electric Power" recently made an online popularization of knowledge about mobile phone charging. The damage to mobile phone batteries mainly comes from two aspects. One is that when the battery is charged and discharged, the cathode and The anode will shrink with the release of the sample, absorb and expand, resulting in a shortened battery life. On the other hand, when the battery is fast-charged, the thermal effect of the current will be aggravated, leading to the rapid accumulation of heat inside the battery, causing deterioration of electrochemical performance and damage to the cell. With the improvement of battery technology and battery thermal management system in recent years, the convenience and safety of fast charging can satisfy daily use, and everyone can use it with confidence.
Speaking of mobile phone fast charging, OPPO as we know it has always been at the forefront of the industry. OPPO has a very early layout for mobile phone fast charging. It has already used 20W VOOC flash in the Find 7 era. And continue to upgrade to the later 30W, 50W, 65W super flash charging, bringing consumers a more efficient charging experience. As for the most important aspect of safety, OPPO also attaches great importance to the 65W super flash charge as an example. OPPO has set up a total of 5 safety protections from the power adapter to the cable to the mobile phone, which can not only monitor the battery status during charging in real time. , It can also monitor whether the battery in the mobile phone is damaged by external force in real time, and multiple protections ensure the safe use of the battery.
On the basis of safety and efficiency, OPPO has gradually popularized 65W super flash charging to consumers, except for the high-end flagship OPPO Find X2 series, such as OPPO Reno4/SE, OPPO Reno5 series and other models They are also equipped with 65W super flash charging, which has truly popularized the 65W super flash charging to the more popular and wider 2K-3K price range.According to official statistics, since its first release in 2014, as of April 2020, global VOOC flash charging users have exceeded 157 million.
However, OPPO has not stopped exploring on the road of fast charging of mobile phones. At last year’s flash charging conference, OPPO also brought a number of fast charging technologies, including 125W super flash charging, which is the highest record of mobile phone fast charging power so far; according to official data, 125W super flash charging is used , It can charge a mobile phone equivalent to 4000mAh battery to 41% in 5 minutes, and it can be fully charged in 20 minutes, and the standby temperature of the screen during the charging process is controlled below 40°C.
In addition, OPPO’s 125 super flash charging technology also continues the safety features of VOOC flash charging. OPPO has set up 10 sensors for monitoring temperature changes, distributed in battery lugs, battery motherboard BTB and USB interface, any Abnormal temperature can be reported to the mobile phone and the adapter as soon as possible. On the basis of the five-fold security protection of the VOOC technology platform, the data line has also imported E-marker encryption, coupled with OPPO's unique 128-bit encryption algorithm, to ensure full charging safety.
At a time when 5G has been widely popularized and mobile phone lithium batteries have not yet been revolutionized, high-power fast charging is undoubtedly the most direct way to solve power anxiety, and OPPO’s VOOC flash charging technology guarantees high Under the premise of power charging, safety is the first priority and continue to bring consumers a more comfortable charging experience. Next, OPPO’s 125W super flash charging will also bring a greater experience improvement. You may wish to look forward to it.
