Is cell phone battery activation necessary?

Is it necessary to activate the battery of a mobile phone. A newly purchased mobile phone must first use up the electricity in the mobile phone, and then charge it, and it must be repeated 3-4 times. This is called activation. It used to be possible to do this, but now mobile phones are all lithium-ion batteries, do not activate at all. The battery of a newly purchased mobile phone does not need to be charged for 12 hours for the first use, but it is best to perform a full charge and discharge process of 3 to 5 hours. Full charge means the normal charge to 100%, and full charge means when the mobile phone is used for low battery reminder. Because the battery has to go through the process of filling electrolyte, forming, charging and discharging, and dividing the capacity before leaving the factory, so that the battery is in the activated state, but after leaving the factory, it takes as little as a month to more than a year to reach the user's hands. Due to the influence of discharge, the battery material becomes passivated. At this time, the battery can be activated through full charge and discharge. This statement that the first three charges should be charged for more than 12 hours is for the rechargeable batteries in the 1990s. The nickel-cadmium batteries at that time have a memory effect and must 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 enough. 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 of a problem, causing serious damage to the battery materials and affecting the capacity and life of the battery. Generally, the charging method described in the manual of the mobile phone is the standard charging method suitable for the mobile phone.
