With the continuous improvement of mobile phone performance and the fact that the mobile phone battery has not substantially increased, more and more people have begun to slow down the anxiety of mobile phone battery life by purchasing a mobile power supply or high-power fast charging, and more and more Android mobile phone manufacturers will take wired fast charging or wireless fast charging as the focus of the force.
In the past two years, when the industry power competition was hot, OPPO, which first promoted mobile phone fast charging technology, did not follow the trend, and chose to maintain a 65W super flash charge for two years. Many people seem that OPPO has been surpassed, but in fact, it is just the opposite, as the most concerned about fast charging performance of OPPO, the focus point is not only on the "power number", but against the pressure of being overtaken by friends, in the face of the pressure of being overtaken by friends, from the power, safety, life, temperature, efficiency, experience and other aspects to create a new generation of fast charging system. Two years later, this big trick finally came out.
OPPO officially released the longevity version of 150W super flash charge and 240W super flash charge at MWC 2022 Mobile World Congress in Barcelona, once again refreshing the record of commercial fast charging speed of mobile phones. Longevity Edition 150W Super Flash Charge can charge 50% of mobile phones with equivalent 4500mAh battery capacity in 5 minutes and 100% in 15 minutes; 240W Super Flash Charge can charge 4500mAh batteries to 100% in 9 minutes. In addition to bringing an extremely fast charging experience, OPPO Longevity Edition 150W Super Flash Charging Technology also has a longer battery life, and laboratory test data shows that after 1600 charge and discharge cycles, the battery equipped with this technology can still maintain 80% of the effective capacity.
At the 2022 Mobile World Congress (MWC2022), smartphone manufacturers have targeted smart fast charging and successively released new fast charging products.
It is understood that previously, the highest charging power mobile phone products on the market were the 135W products of the Red Devil 7 Pro, as well as 120W products such as iQOO7, Black Shark 4Pro, and Xiaomi 12 Pro. Nowadays, 100W fast charging is no longer rare, and manufacturers have repeatedly refreshed the charging speed of smart phones.
The new product goes further in the fast charging technology, of which the Honor Magic4 Pro is equipped with a 4600mAh capacity battery, supports 100W wired super fast charge and 50W wireless super fast charge, wired 30 minutes can be charged to 100% of the power, and the overseas version supports 100W wireless super fast charge.
Realme's 150W light speed second charge released this time can achieve 50% charging in 5 minutes, and will be launched on the True Self GT Neo3. It is understood that realme released the true self X50 Pro equipped with 65W fast charging technology in 2020; in July of the same year, realme announced 125W fast charging technology.
In the past three years, the power of the fast charging industry has risen to 120W, 150W, and will soon increase to 240W, and it is foreseeable that the fast charging industry will continue to develop at a high speed. The charging power and power density of fast charging products continue to increase, and relatively speaking, the volume of fast charging products is getting smaller and smaller. With the increasing complexity of product use scenarios, the safety problems of fast charging are becoming more and more prominent.
Charge faster and more steadily
In fact, in simple terms, charging is a physical problem, and the principle of fast charging is to shorten the time required for charging by increasing the charging power. There are three ways to increase the power, namely to increase the voltage, increase the current and increase the voltage and current at the same time; the above technology is derived from these principles.
Nowadays, high power is no longer the only power point of fast charging. The battery cell has also become the object of attention of mobile phone manufacturers, just last year Xiaomi first self-developed charging chip surging P1, the product to achieve a single battery cell 120W wired second charge. According to the official introduction, the surging P1 takes over the complex structure of the traditional 5-charge pump, converts the high-voltage power input into the mobile phone more efficiently into a large current that can be directly charged to the battery; has a 4:1 ultra-high efficiency architecture with adaptive switching frequency, and the resonant topology efficiency is as high as 97.5%, so that the endurance and charging performance reach the best balance.
It should be noted that mobile phone manufacturers can not blindly pursue fast charging, charging safely and not hurting the battery is equally important. In the fast charging scenario, the user's mobile phone security and battery life can be guaranteed to the greatest extent.
At last
At present, mobile phone fast charging technology is in a stage of rapid development, in the future, we may be able to see that the mobile phone full charge will be a matter of minutes, before going out can also be quickly charged. But as an Android mobile phone user, at present for me, the battery capacity is really related to one of the important factors related to the endurance of the mobile phone, I personally do not want to cause the mobile phone battery capacity to become lower because of high-power fast charging, 240W high-power fast charging although it can shorten the charging time, but can not effectively solve the phone endurance anxiety.
