3v Button battery

Will mobile phone fast charging technology affect the life of 3v Button battery?

Smartphones have become an important tool for people to maintain their daily lives. At the same time, as users become more dependent on mobile phones, the limited storage capacity of mobile phone lithium batteries conflicts with users' high demand for smart phones. Since the development of the first generation of "big brothers", mobile phones have been developing towards the "light and thin" route. Therefore, in order to solve this contradiction, fast charging technology was born.

First of all, let's understand what fast charging technology is. At present, the fast charging technology on the market is mainly divided into high-voltage fast charging and low-voltage fast charging. Among them, high-voltage fast charging has been gradually eliminated by the market because of the excessive heating of the body during charging. As for low-voltage fast charging, it has been widely used in the market because it does not have the above-mentioned disadvantages. For example, Huawei mobile phones and OPPO mobile phones all use low-voltage fast charging technology.

I believe that many users have had this question, that is, is fast charging technology related to mobile phones or chargers? "Fast charging" as a complete set of technical processes cannot be completed independently by mobile phones or chargers alone. It requires the built-in power management chip of the mobile phone, the charging cable and the charger to coordinate and cooperate to realize this technology. Therefore, for mobile phones that do not support the fast charging function, even if a "charger that supports fast charging" is used, fast charging cannot be completed. On the contrary, if you are a user of iPhone 8 or above, even if your mobile phone supports the fast charging function, but is not equipped with a corresponding fast charging charger, fast charging cannot be achieved.

After understanding this, let's take a look at whether frequent use of the fast charging function will damage the mobile phone battery and reduce the battery life. When our smartphones are charged normally, the charging current is not constant. When our mobile phones are in a low power state, the built-in power management chip of the mobile phone will send a signal to our charger, and then the charger will speed up the charging of the mobile phone. When our mobile phone has 60% to 80% of the power (the setting range of different brands of mobile phones is different), this built-in chip will send a signal to the charger to slow down the charging speed, thereby reducing battery loss, protecting the battery, and slowing down heating. As for when we use fast charging to charge the mobile phone, the battery will be in a state of high current for a long period of time to replenish the power of the mobile phone, so compared with ordinary charging, fast charging will theoretically cause more damage to the battery. But this damage will not affect our normal use, nor will it make the life of the lithium battery not meet the expected use, so if your mobile phone supports fast charging technology, you can use it with confidence.

Finally, some friends may not know whether the charger they have supports fast charging technology, so here are some ways to identify it. First of all, the standard chargers of Apple mobile phones do not support fast charging. Android phones can be identified by checking whether there is a "circle fast charging" logo in the charging head, because this logo means that it supports Qualcomm QuickCharge technology. At the same time, you can also observe whether the charging head is marked with "fast charger" and other words to identify it. If you have any questions about fast charging technology, you can leave a comment to tell the editor.
