A stumbling block to the development of smartphones-battery technology. Competition in the smartphone market is becoming increasingly fierce. As we reported before, more and more smartphone operating systems are working hard to expand their market share, and manufacturers are also working hard to increase their share of the smartphone market. More and more smartphones are coming out, their functions are becoming more and more powerful, and their configurations are getting higher and higher. All this shows that the smartphone market is growing rapidly.

　　However, the development of smartphones has not been smooth sailing. Although technology is developing at a rapid pace, and more and more new technologies are applied to the mobile phone field, which has greatly improved the user experience, there are still some bottlenecks that restrict the development of mobile phone technology. Battery technology is one of the most important aspects.

　　Warning: Battery is low!

　　Compared with ordinary mobile phones, smart phones often have higher hardware configurations than ordinary mobile phones. Moreover, smart phones with more functions are also used more frequently. This means that the power consumption of smartphones is correspondingly greater. As large-size touch screens become mainstream and there are more and more Internet-based applications, the power consumption of smartphones continues to increase.

　　Inconsistent with this development, mobile phone battery technology has not made much breakthrough. Compared with a few years ago, the current battery capacity of smartphones has only improved to a very limited extent, and its battery life is difficult to satisfy users. According to the author's understanding, many smartphone users now need to charge the battery every day.

　　Henry Tirri, head of Nokia Research Center, said in a recent interview that it will take several years and after breakthroughs in related technologies are made before the battery life of smartphones can reach a "good" level. Henry TIrri believes that a "good" level of smartphone battery means that it can be used for about a week on a single charge, but now many high-end large-screen smartphones can be used continuously for less than eight hours.

　　It is difficult to make a breakthrough in mobile phone battery technology in the short term

　　Shortcomings in battery technology have implications for both operators and manufacturers. Users may be hesitant to buy a smartphone with a short standby time, and this also limits users from using their smartphones for more Internet applications.

　　Some smartphones cannot replace the battery

　　Henry TIrri said that since the basic functions of mobile phones are voice and information, previous research on mobile phone power management was mainly optimized for these two aspects. However, in the past two years, with the rapid development of mobile phone technology, faster and more power-consuming processors and larger and brighter screens have appeared. With the emergence of the concept of "cloud", a large number of applications have It needs to be connected to an Internet server, which also consumes a lot of power. However, battery research has not kept up with this trend.

　　Due to limited size and safety considerations, it is difficult to significantly increase the capacity of lithium batteries currently used in mobile phones. Mobile phone manufacturers and battery manufacturers are researching new battery technologies, including the use of light energy, kinetic energy, etc. However, there is currently no substantial breakthrough in these technologies and they cannot yet be widely used. Michael Morgan, an analyst at ABI Research, said that breakthroughs in smartphone batteries involve many technologies, and these technologies are related, and the development of each technology must wait for the development of other related technologies.

　　Therefore, while enjoying the faster speed and richer functions of smartphones, for a period of time, smartphone users still have to endure the pain of batteries that do not last long. And if this situation cannot be improved as soon as possible, it may even have a huge impact on the development of the smartphone industry.
