The laptop's life

In the past two years, the power consumption and endurance of electronic products have gradually gained the attention of consumers and manufacturers, including chip manufacturers and OEMs. With the rise of the mobile Internet industry and the arrival of the post-PC era, endurance has gradually become one of the most important indicators of how to evaluate a product. It has been upgraded to a processor a few years ago.

The core manufacturers <br> <br> fact, from some of the core companies of the action now, we can see that the power consumption of products and their life is the focus of the current research and development direction. The new generation of Haswell architecture processors introduced by Intel in the second half of this year has not much improved processor performance compared to the previous generation of IVB architecture processors. However, with the same manufacturing process, its endurance capacity is A huge increase. The MacBook Air equipped with Intel Haswell processor has been able to reach a life time of about 13 hours. The AMD side, which is also the next-generation APU product launched in the second half of this year, has achieved the lowest power consumption at the single-digit level. It can be seen that the endurance capacity is in the eyes of the upstream core manufacturers.

<br> <br> and OEM manufacturers in the OEM side, as there is every new release, the product of life, are also the focus of its propaganda. However, we are now gradually seeing a lot of traditional notebook computers, starting to carry low-voltage processors from Intel, and of these, the OEM is also for the product's battery life. Now the author's feeling is that the importance of product life, has gone beyond the importance of the performance of its products, OEM at the expense of some product performance, but also to increase their life. Is the product's battery life really important for the average consumer? Is this really meaningful, or is it just a publicity gimmick?

Below, the author tells about some of his personal experiences. As an IT editor, I often miss friends and recommend products. When I ask them what they want from the product, the most frequently answered questions are the price range. You can use Office, PS, or any game without a card. There is weight in the shape. However, people who ask how this notebook lasts are relatively less, and those who are concerned about the life time are often those of us. Do not know when the majority of users in the purchase of notebook products, how many people are really their endurance, as a measure of whether to buy a product? I think the proportion should not be too much.

Market demand <br> <br> Of course, in this respect the needs of the case, surely someone will focus on endurance. What kind of person needs a product that has a longer life? According to the author's observations, there are so many people who have higher requirements for the product's endurance. First, friends who often meet and have a longer meeting time. This is still more often seen in the author's usual work. Sometimes one-on-one meetings are held one after another. Then one can see that somebody ran back to the station to get an adapter. Second, friends who travel frequently and have a long journey. The longest class time in China is five hours, but in most cases, basically within three hours, and the high-speed rail time is longer, but the high-speed rail is equipped with a power plug, slightly better.

Maybe the author's life experience is less, perhaps it is the lack of understanding of other industries, but in my friends, basically only these two kinds of people, the demand for laptop's life ability is higher. And the higher here is only within 6 hours. So what I would like to say is that the laptops that have a life time of more than ten hours now really make sense? The only point that I can think of is that in order to ensure that after a certain period of use, the battery can still have good endurance after being worn out. The author's original notebook computer lasted for a maximum of 7 hours, but after one year, it was about 5 hours. However, such endurance capacity has been fully able to meet the needs of my daily meetings and business trips.

How to choose the <br> <br> In fact, I want to express, life is not completely useless, I just want to tell consumers, at the time of product selection, or should be purchased according to their needs, do not blindly listen to some publicity of OEM Don't follow suit. First of all, for the student user, it is basically impossible to consider the product's life factor unless there are special needs. College students to buy more laptops to consider is easy to carry, their products for a long time in the bedroom, as long as the dormitory does not power, I can not think of what will continue to use the battery more than 5 hours. Secondly, home users, now that the price of editing products is decreasing, many families will use laptops as home PCs to save space. This kind of basic usage is not as effective as battery life.

In addition, the product's endurance and product performance are inversely proportional to the ideal situation. Under the same battery capacity and technology, the low-power product performance is relatively weaker than the standard power consumption. Low-power products often use low-voltage processors and core graphics cards. Although there are no problems in daily entertainment and office work, the performance of the products will be lower than that of standard voltage products. Similarly, the life of standard voltage products will be slightly inferior to low-voltage products.

The author's point of view:

The reason why I want to write these contents is simply to let everyone know the needs of their products and buy products that are truly suitable for them. The battery life as an important parameter of the laptop product certainly has its own meaning. In some unexpected situations, long-term battery life may help you to save your life. However, compared to flat-panel and mobile phones, which are extremely sensitive to life, the laptop's requirements for battery life are really not that high. It is still the best and the right one.
