Will the battery life of the mobile phone be affected by the fast charging technology of the mobile phone?
Smart phones have now 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 power storage capacity of mobile phone lithium-ion batteries conflicts with users' high demand for smart phones. Since the development of the first generation of 'Big Brother' to the present, mobile phones have been continuously developing towards the 'light and thin' route, so in order to solve this contradiction, fast charging technology was born. First of all, let’s understand what fast charging technology is. The current fast charging technologies on the market are mainly divided into high-voltage fast charging and low-voltage fast charging. Among them, high-voltage fast charging has been gradually due to the excessive heating of the body during charging Eliminated by the market. As for low-voltage fast charging, because it does not have the above drawbacks, it has been widely used in the market. 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. Is the fast charging technology related to mobile phones or chargers? 'Quick charge' is a complete set of technical processes. In fact, this process cannot be done independently by a mobile phone or a charger alone. It requires the coordination and cooperation of the built-in power management chip of the mobile phone with the charging cable and the charger to realize this technology. . Therefore, for mobile phones that do not support fast charging, even if you use a 'charger that supports fast chargingConversely, if you are an iPhone 8 or higher model user, even if your mobile phone supports fast charging, but is not equipped with a corresponding fast charging charger, then fast charging cannot be realized. After understanding this, let's take a look at whether frequent use of the fast charge function will damage the battery of the mobile phone, thereby reducing the service life of the battery. When our smart phone is charged normally, the charging current is not constant. And when our mobile phone is 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 to replenish the power to the mobile phone. When our mobile phone has 60% to 80% 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 the loss of the battery, protecting the battery, and slowing down fever. As for when we use fast charging to charge the mobile phone, the battery will replenish the power of the mobile phone under the state of high current for a long period of time. Therefore, compared with ordinary charging, the fast charging theoretically will damage the battery. Bigger. But this injury will not affect our normal use, nor will it cause the life of the lithium-ion battery to fail to meet the expected use, so if your mobile phone supports fast charging technology, you can use it with confidence.
