To be clear, wireless fast charging does not reduce battery life. So why do many people think that wireless fast charging will affect battery life?
The biggest advantage of wireless charging is to get rid of the data cable, and the charge is put and taken, so some users suspect that frequent charging and power off will reduce the service life of the mobile phone battery.
This idea is wrong, now the mobile phone is used lithium batteries, lithium batteries are no memory effect (nickel-metal hydride batteries have memory effect), \"with charge\" but more conducive to maintaining the activity of lithium batteries, that is, do not use low power, do not charge too full.

Previously, Apple's official response to the \"reduced frequency gate\" explained that the iPhone battery can retain up to 80% of the original power storage after 500 full charging cycles, and after the battery storage is less than 80%, the power consumption will be accelerated, and the efficiency will be affected. The single-charge cycle of the mobile phone refers to the battery from fully charged to completely consumed, not the number of charges.
Under what circumstances will the battery wear out?
1. Wrong charging habits. Most smartphones use lithium batteries, of which lithium ions are active, if the phone is over-discharge, it will certainly affect the battery life. Therefore, try not to start charging when the phone enters the \"low power mode\
2. The battery temperature is too high. The most afraid of lithium battery is the irreversible damage caused by high temperature, the normal working temperature of the general mobile phone is between 0 and 40 ° C, the temperature is too high or too low, will cause a certain degree of damage to the battery.
3, charging equipment is not qualified. The use of unqualified third-party chargers and data cables without over-voltage and over-current protection will cause unstable charging power and damage the battery cell.
03 Examples Describe models that support the wireless fast charge technology
At present, the biggest drawback of wireless charging technology is that the temperature is too high, and mobile phone manufacturers are also solving this problem, and domestic flash memory technology like OPPO is excellent. April 13, OPPO Ace2 online release, the new machine is equipped with 65W wired 40W wireless fast charge 10W reverse wireless charging combination, its mass production speed of 40W wireless flash charging technology, faster than most of the market wired fast charge speed, the wireless fast charge to a new height.

It uses a series dual cell architecture, only need to charge the base - the receiving coil 1 buck, charging efficiency is higher, heat is lower. In addition, the wireless charging board is equipped with air-cooled heat dissipation, so that the back temperature of the charging is below 40 °C, the charger is compatible with the mainstream Qi charging standard, and can charge other devices that support wireless charging.
Others like Samsung S20 series, One plus 8 Pro, Huawei P40 series and Xiaomi 10 series, etc., all support wireless charging function, although the charging power is different, but it is always a leading role in the industry.

Write at the end
The wireless charging function gets rid of the trouble of the data line, the correct charging method technology innovation does not need to worry about battery loss, the most important thing is to charge with the release, for office workers, the use of fragmented time can quickly replenish the power, convenient and fast. The future must be a wireless world, and wired fast charging, I believe that the next wireless fast charging will slowly spread.
1, wireless flash charging mode needs to match the corresponding specifications of the charger, data line to achieve wireless flash charging, please use the mobile phone standard charger and data line to charge, such as: 120W or 66W original charger and standard data line to achieve 50W wireless flash charging;
2, please put the mobile phone correctly, wireless charging coil deviation is too large, may lead to low charging efficiency or can not charge, please put the mobile phone left and right center on the base;
3, different brands of mobile phones due to the difference in coil position, may lead to low charging efficiency or can not be charged;
4, do not use too thick or magnetic insulation material protective shell, may affect the charging efficiency or can not be charged, or even overheating to cause the phone can not be charged or damaged;
5, when the phone temperature is too high, please wait for the phone to cool down before charging.
