With the development of smart phones, one charge a day has almost become the norm for modern people to use mobile phones, because even if the mobile phone is getting bigger and bigger, the battery seems to be unable to keep up with the speed of development. In particular, the performance of the flagship, e-sports mobile phone, the more powerful the power consumption is more considerable, prompting many brands to seek faster charging speed to make up for the battery problem.
Many brands have launched so-called 100W fast charging technology that can complete mobile phone charging in a very short time, such as vivo's iQOO fast charging technology can reach 120W fast charging, Red Rice's 125W UltraDART, Oppo 125W wired charging (wireless charging support 65W).
According to Oppo's official statement, the 125W fast charging technology can fully charge the 4,000mAh battery in 20 minutes, while vivo's iQOO claims that it takes only 15 minutes, and Xiaomi's 100W takes only 17 minutes to charge from 0% to 100%. Almost all said that they can charge a third of the electricity in the first 3 minutes, and can reach 40% in 5 minutes, and then gradually decrease.
Do we really need such a fast charging feature?
Looking at the reaction of netizens, some people believe that fast charging technology will cause harm to the battery. The brand ensures that the phone does not overheat by adding induction modules, or divides the phone battery into two pieces, for example, the 4,000mAh battery is divided into two groups of 2,000mAh, and uses two to three charging loops to achieve double the charging speed. Of course, such a design would also increase the manufacturing cost of the phone.
The quality of the battery is almost difficult to determine, because it is likely to reflect the manufacturing cost of the fast charge on the battery quality, that is, the use of small capacity and ordinary quality batteries. On the contrary, some batteries with a capacity of up to 5,000 and 6,000 mAh do not support super fast charge technology (more than 100W), but the quality may be better.
A large battery with a high capacity is equivalent to a 100% small battery at 80% power, due to the relationship between the battery charging mechanism, the final 10-20% charging is very slow, which also means that the mAh obtained by the large battery in the final charging time will be more stable than the small battery, and it can complete the last 20% charging faster.
? In addition to battery quality, the current specifications of the super fast charge are still not unified, and each has its own special rules. The fast charging dock used on behalf of the user cannot be connected, let alone used to charge non-mobile devices (such as laptops, Nintendo Switch). Therefore, even if the super fast charge has appeared on the market, it still takes some time to improve and unify the specifications.
Mobile phone 20 minutes can probably be charged less than 20% of the electricity, because most of the current chargers are more than an hour to be fully charged, urgent charge and slow charge are not good for the battery, easy to shorten the battery life
Probably can charge a dozen batteries, but also look at what mobile phone
