Who is the secret to determine the battery life of the Bluetooth headset?

Many netizens consulted about the purchase of earphone products. Among the netizen consultation questions received, a considerable part is concentrated on wireless headsets and Bluetooth headsets, and the problem is quite clear, that is, they all need a longer battery life. Wireless headset or Bluetooth headset products. However, as far as the current market situation is concerned, it seems that it is not particularly easy to solve this problem, because a considerable number of wireless headsets are lost in battery life, mostly concentrated in 4-6 hours. Life time makes many users for wireless headsets "I don't want to say that it is not easy to love you."

Life time is very important for wireless headphones, which directly affects the user experience is good or bad. Longer battery life can guarantee to reduce the number of times of charging within a certain period of use, the use experience is almost the same as wired headphones; The battery life will be recharged frequently, especially the wireless headset that lasts less than one day, and it feels awkward to use.

How does the wireless headset supply power? At present, it seems that the battery is the only solution, so the battery life of the wireless headset is largely determined by the built-in battery. The current mainstream battery power supply scheme is roughly divided into replaceable dry batteries and There are two kinds of built-in rechargeable lithium batteries. The former can be replaced at any time. It is very convenient to use, but the cost is slightly higher. The latter needs to pay attention to the remaining power. If there is no electricity in the outdoor, there is no way, but almost No cost of use.

"In order to extend the battery life, we try to use a larger battery. The battery capacity is longer. The longer the battery life is." Of course not. The size of the battery is only a part of the battery life, not all. And the built-in lithium battery is affected. The limitations of cost, space, weight and safety are not likely to be very large.

In addition, the larger the built-in lithium battery, the longer the charging time, the higher the manufacturing cost, the higher the risk factor, and the weight of the earphone will increase. According to the above considerations, the current mainstream Bluetooth wireless headset is built-in. The battery has reached the limit, if you want to make a breakthrough, you can only hope that the lithium battery has a revolutionary development.

Since the battery can not increase the capacity without limit, then power saving is a must to extend the battery life. As far as the current Bluetooth wireless headset is concerned, the advanced algorithm is very beneficial to improve the battery life of the wireless headset. How to understand this matter What? Advanced algorithms help the headset to decode quickly and efficiently, without having to perform too many steps to achieve the effect, this is the main purpose of advanced algorithms.

In the era of Bluetooth 4.0, Bluetooth technology is very mature, and it can be compatible with most of the Bluetooth audio sources on the market as the mainstream of wireless connection. As far as the individual Bluetooth 4.0 technology is concerned, it can meet the needs of lossless audio transmission, and also Both data transmission and data encryption functions. From these points of view, Bluetooth 4.0 has occupied an absolute leading position.

How long is the battery life enough? On the one hand, it is to increase the battery capacity, on the other hand, it is to save power, so as to extend the battery life of the wireless Bluetooth headset. Then, the lossless music playback of large data volume will increase the consumption. What about electricity?

The answer is no. From the specification of Bluetooth technology, the transmission rate of the Bluetooth carrier is certain, that is to say, no matter what quality music is played, the power consumption is calculated by the full bandwidth of Bluetooth, which does not depend on The small sampling rate bandwidth is narrow, the high sampling rate bandwidth is wide, and Bluetooth does not have an adaptive algorithm.

Therefore, the power consumption of the Bluetooth wireless headset is certain when playing music, and it does not depend on the type of music being played. Therefore, in the case of big data throughput, the power consumption of the Bluetooth headset does not increase dramatically. Some Bluetooth The headset will add some intelligent functions, such as automatic shutdown when there is no data transmission, in order to save power. However, the means is still a means, can not completely solve the problem of power saving.

How long does it take to be a wireless headset? The personal opinion must be as long as possible, but obviously this is not possible. In terms of general usage habits, mainstream wireless headphones must meet the needs of the day. Demand. After deducting the time of eating and sleeping, according to the longest battery life, 8 hours should be a more reliable data.

Above this data, there is naturally no problem, but below this number, it is generally not very convenient to use. However, it should be noted that users who can use the wireless headset for 8 hours a day are examples and cannot represent the mainstream. User's use requirements, here we only list the use of the scenario, does not represent the actual situation.

In addition, some good usage habits also help the wireless headset to extend the battery life, such as turning off the power when not in use, and better protection for the lithium battery, prolonged life is probably the meaning.

From the above analysis, there are many reasons for affecting the life of wireless headphones, but there are three reasons: battery capacity, power consumption and power saving. If users need to extend the use time, they can try to start from these three aspects. To be honest, this The performance of the secondary wireless headset horizontal evaluation battery life has been quite satisfactory, and the players of more than 20 hours are really staggering. After all, it is only a few hours to see this thing a few years ago. The current wireless headset can fully meet the actual needs. And exist!
