Finally, after reviewing 5G, taking pictures, folding screens and chips, let’s turn our attention to the key to driving all these experiences in the mobile phone-the battery.
Yes, 5G requires more than a dozen or twenty antennas, which consumes a lot of power; the large and super-large camera module has good image quality, but it also consumes a lot of power; although the folding screen form is new technology, a larger screen is also inevitable Bring more power consumption; not to mention new chips with greatly improved performance … In short, no matter what technical progress is made, basically at the expense of power consumption

As a result, the problem of small improvements in mobile phone battery technology throughout 2019 has also emerged. Although strictly speaking, there are still some improvements. For example, today, large-capacity batteries of 4500mAh or even 5000mAh have been used, and these batteries are also generally designed with ultra-low internal resistance, so as to be compatible with high-power fast charging. At 40W, With the support of 45W or even 65W super fast charging, half an hour or forty minutes of full charge is nothing new. But in terms of improving the user experience, super fast charging is, to some extent, obviously far less important than 5G, camera and higher performance.
However, although mobile phone manufacturers know how to make batteries larger and are also working hard to develop ultra-fast charging technology, the energy density of the battery itself has made little progress in the past year. And the result is that under the joint efforts of improving performance, faster network speed, enhanced camera, and larger battery, many of today’s products have become large, thick and heavy “half-pound machine, brick machine”.

I have to say that this is indeed a frustrating situation, but because of the prevalence of bad conditions, this may have inspired some manufacturers to pay attention to this problem and try to solve it. For example, just recently, it was reported that Samsung has equipped a special 5000mAh battery from LG on the Galaxy S11 +. The reason why it is special is because LG does not know what black technology is used (is it from an electric car battery Group technology?), The density of the new battery has been increased by more than 50%, making the 5000mAh battery even smaller than many 3000mAh batteries.
Obviously, if LG’s technology can prove its reliability, then it will hopefully become the biggest technological breakthrough in the smartphone industry in 2020, without one. Of course, if this brand-new battery is a kind of high-cost black technology product, it also means that at least for a period of time, it will only be a flagship product like the Galaxy S11 +, Apple iPhone 12 Pro MAX, etc. If the equipment you enjoy is expected to be popularized, you may have to wait a few more years.
