5 misunderstandings of mobile phone battery charging

Misunderstanding 1: Always plugged in the charger will damage the battery. Many people think that charging overnight will damage the phone battery, but this is not the case. Current mainstream mobile phones are equipped with smart ICs, which can automatically stop charging when fully charged. Misunderstanding 2: The theory that the mobile phone is charged only when it is out of power is applicable to the early nickel-metal hydride batteries, but the lithium-ion batteries that are standard on mobile phones are completely unnecessary. Ni-MH batteries need to be charged after being fully discharged because they have a memory effect, while lithium-ion batteries do not have this problem, so they can be charged at any time. Misunderstanding 3: The battery will be damaged as the number of recharges increases. Previously, it was generally believed that the lithium ion of the lithium-ion battery would lose its vitality as the number of recharges increased, causing the battery life to run out. However, Apple explained that the life of the lithium-ion battery It depends on the charging cycle rather than the number of times. To put it simply, for example, if you charge your mobile phone to 50%, and then charge it again after using it up to 50%, this is a complete charge and discharge cycle. Misunderstanding 4: Don't use the mobile phone while charging. Although there have been cases where the user was electrocuted when using the mobile phone while charging, it is actually not a problem with the mobile phone or battery technology. What happens is nothing more than using a charging mobile phone in a pool or bathtub, or using a cheap, non-guaranteed counterfeit charger. Genuine mobile phones and chargers have current protection measures, and the maximum voltage is far lower than the maximum voltage that the human body can withstand. Myth 5: Third-party batteries and chargers are not safe. In fact, this view has some truth, but it is not absolute. Mobile phone manufacturers recommend that users purchase original accessories to ensure that no accidents occur. And third-party batteries and chargers certified by manufacturers are basically big brands, and safety issues rarely occur.
