The use of lithium batteries drag 3G speed
"Why do you have an old cell phone can not get through?" Mr. Zhang, laptop battery a friend expressing his dissatisfaction. "I beg your pardon, because the cell phone power too fast, no electricity in one night." Mr. Zhang, such a helpless response. Despite his hand on the Taiwan 3G phone features numerous, but the cell phone battery power left him very much a headache Fast.
It is understood that, from 2G to 3G, from GSM, CDMA to the WIFI, WAPI, from voice calls to video phones ... ... mobile phones more and more functions, consequential, battery consumption and faster. Experts said that the current cell phone battery technology innovation can not catch up much faster pace of innovation in mobile phones, mobile phone battery capacity has become a major constraint to use 3G important factor.
2G times the battery has been insufficient
Your cell phone battery enough? If your cell phone or a black and white screen, your business needs is just voice and text messages, then your cell phone Presario X6000 battery a few days will be enough. However, if your cell phone is a 24-hour mobile IM-line, with large cell phone screen, you often use it to listen to music, browse the Internet, watching video but also making video calls, then I am afraid you are at least two a day in turn replaced the battery.
In fact, the mobile phone battery in a growing number of applications has begun 2G is not enough to use. According to report, at present to buy mobile phones, basically equipped with a standard battery of 960 milliamperes. But it is clear that if you want to songs, take pictures, the Internet, which a standard mobile phone battery is not enough. According to industry insiders, mobile phones since the development of the lithium battery, besides ensuring the mA can be done at the same time is smaller and slimmer than on no greater technical progress. So people tend to buy more than one mobile phone batteries to carry, to prepare for contingencies. A growing number of mobile phone brands Presario R3000(compaq r3000 battery) have begun with two standard batteries.
Number of domestic mobile phone brands and third-party mobile phone battery factory began to realize that consumer demand for mobile phone battery. According to insiders, a number of domestic brands in order to promote sales, equipped with two 1000 milliamperes even greater capacity of the battery. The third-party vendors for certain best-selling brand of production more than the original "thick power."
However, the problem seems to remain unresolved. To get rid of "recharge every day," and even "a few hours to recharge a battery", the only option seems to be the feature-limited mobile phone. Communications Design Institute of Sichuan, as Senior Consultant Cheng Dejene said: "Now the development of battery technology has been lagging far behind the PP2100 development of electronic technology."
3G mobile phone power consumption is even more astonishing
With the 2009 China has entered 3G era, a small mobile phone battery appears to be growing into a serious major problem. In the 3G era, mobile phone access to the Internet, games, video and audio will be further widely used. However, all these applications require a long time on the phone operation, needed a mobile phone battery can support a longer time. The hardware configuration of the climb, CPU processing speed improvements, a larger higher resolution screen size, also need power protection.
3G portal a recent survey shows that 74% of the 5000 User believes that 3G mobile phone battery capacity is an important factor constraining.
Different businesses, for electricity consumption is not the same. For example, the video is far greater than the reading class of business class on the business of electricity consumption. Although it is already a lot of new battery technologies, such as fuel cell technology and so on, but it must be to the terminal, DP390A there are a considerable distance.
However, some industry analysts say there is no need for battery constrained the development of 3G to be too pessimistic. CCID Consulting analyst Zhang Jing-tao that the 3G battery is indeed a significant factor, but can not say that the biggest bottleneck. Zhang Jing-Tao that, like Japan, South Korea's 3G push very well, the battery does not become a bottleneck, he said, high-performance battery technology itself, and not many bottlenecks. At the same time, Zhang Jing-Tao believe that battery technology is far more difficult than upgrading a wide range of 3G value-added type business itself. He said: "Although 3G phones will not be used, as well as 2G few days without charging, but if it is feature-rich, easy to use, tariff is reasonable, to meet the individual needs of consumers of mobile phones, even if the charge will not let a day and consumption of those who feel very bad. "
There are three ways to solve the battery problem
How to solve the problem for the mobile phone battery, industry sources pointed out that the following three methods:
First, the invention of new batteries. There are Japanese manufacturers have already demonstrated a conceptual fuel cell technology. This drive through the fuel cell HSTNN-UB02 can make the Internet a few weeks of this continuous work. This technology is likely to be applied to mobile phones. The conceptual wide range of solar cells also started to enter the field of study.
Second, inventing new cell phone. Have a mobile phone manufacturers plan to launch the "Power King" of the phone, whose design concept is a lithium battery-powered, the addition of a battery slot, you can use normal on the 7th battery.
Third, and set up mobile phone charging stations. It is understood that earlier in Guangzhou "popular front", sports, West subway station have appeared in places such as mobile phone charging station, only to pay for the amount, you can more than ten minutes, fast charging for cell phones. Guangzhou city, HSTNN-DB02 some operators have also been in the business hall launched a free mobile phone charging service. The other cities have also seen a similar phenomenon.
