Wireless charging is harmless to the battery, because the current working frequency of wireless charging is below 1M, so it will not affect the signal of the mobile phone. On the contrary, the wireless charger not only reduces the use of data lines, but also makes the charging method more free and safer. It is basically the same as wired charging, but the rate is lower, but the power conversion rate of the wireless charger is still very high, which saves energy consumption even more.
Some people feel that the reason why wireless fast charging hurts the phone
This is mainly due to concerns about frequent charging. The biggest advantage of wireless charging is that there is no need for wires. Every time you charge, you can put it on and take it with you, which reduces the trouble of plugging in the mobile phone charging cable. So some people suspect that frequent charging and turning off the power will reduce the service life of the mobile phone battery.
Types and principles of wireless charging
There are four main types of wireless charging: electromagnetic induction, magnetic resonance, radio waves, and electric field coupling. At present, the wireless charging of most mobile phones uses electromagnetic induction. This method is to charge the mobile phone by letting the power supply current flow through the transmitting coil to generate a magnetic field, and then bringing the receiving coil of the mobile phone close to the magnetic field to generate current. The efficiency of electromagnetic induction is higher than that of magnetic resonance, so it is widely used in the field of mobile phone wireless charging.
The impact of wireless charging on mobile phone batteries
Wireless charging is better for batteries and can actually extend battery life, but it depends on how you use it and how often you charge it. Unlike wired charging, wireless charging can be used throughout the day. Wired charging users generally run to charge when the battery power is “red” or below 20%. Low battery conditions not only have an impact on battery life, but also cause many people to experience “low battery anxiety”. Wireless charging generally places chargers at home, in cars, in offices, and in coffee shops. This way, the phone can be charged while the user is driving or going to a coffee shop (which is not necessarily a low battery state). Also, charging the battery to around 50% is more beneficial to the health of the battery than fully charging it.
