  • How to charge mobile phone battery

    Mobile phone batteries are energy storage tools that provide power to mobile phones. Mobile phone batteries generally use lithium batteries and nickel-metal hydride batteries. Mobile phone batteries generally consist of three parts: a battery cell, a protection circuit, and a shell. "MAh" is the unit of battery capacity

    Regarding the "activation" problem of lithium batteries, many claims are: the charging time must exceed 12 hours, and full charge and discharge are repeated three times to activate the battery. This statement of "the first three charges must be charged for more than 12 hours" is for rechargeable batteries in the 1990s. The nickel-cadmium batteries at that time had a memory effect and needed to be fully charged to ensure battery capacity. The mobile phone uses a lithium ion battery, which has no memory effect. Generally, it can be fully charged in 2-3 hours, which is sufficient. If the first three charging and discharging of the new battery can really reach 12 hours or more, it will cause great damage to the battery, and may cause the battery to swell or even burn. Fortunately, both the mobile phone and the charger have protection circuits. When it is charged to 100%, it will automatically power off, and it will not continue to charge when plugged into the charger. However, it is better to unplug the charger at this time to prevent the charger's protection circuit from overcharging in case a problem occurs, causing serious damage to the battery materials and affecting the capacity and life of the battery. Generally, the charging method described in the mobile phone manual is the standard charging method suitable for the mobile phone.
