The newly bought mobile phone needs to be used up first, and then recharged, and it needs to be repeated 3-4 times before it can be done, which is called the so-called activation. This used to be possible, but now phones are all lithium-ion batteries that don't require activation 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 charging and discharging process for 3 to 5 hours. Full charging means that it is normally charged to 100%, and full discharging means that the mobile phone is used to remind when the battery is low.

Because the lithium-ion battery needs to go through the process of electrolyte filling, formation, charging and discharging, and capacity distribution before leaving the factory, the lithium-ion battery is in an activated state, but it takes as little as a month or more than a year to reach the user after leaving the factory. , Due to the influence of the self-discharge of the lithium-ion battery, the battery material is passivated. At this time, the lithium-ion battery can be activated by full charge and discharge.

The statement that "the first three charges should be charged for more than 12 hours" refers to rechargeable batteries in the 1990s. The nickel-cadmium batteries at that time had a memory effect and needed to be fully discharged to ensure the battery capacity. The lithium-ion battery used in the mobile phone has no memory effect and can be fully charged in 2-3 hours, which is sufficient.

If the new battery can be charged and discharged for 12 hours or more in the first three times, it will cause great damage to the lithium-ion battery, which 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 it is plugged into the charger. However, it is better to unplug the charger at this time to prevent the lithium-ion battery from being overcharged in case of a problem with the charger protection circuit, causing serious damage to the battery material and affecting the capacity and life of the lithium-ion battery. Usually, the charging method described in the mobile phone manual is the standard charging method suitable for the mobile phone.

The correct use of mobile phone lithium-ion battery:

1. Avoid excessive discharge, try not to use the mobile phone below 20% of the power, especially do not use the mobile phone below 5% of the power, it will cause irreversible damage to the battery.

2. Avoid overcharging. Over discharging and overcharging will cause great damage to the lithium battery of the mobile phone. However, at present, smartphones generally have circuit protection, and they will not continue to charge the battery after fully charged.

The ideal state of a lithium-ion battery is when the power is still 40%. At this time, the voltage of the battery is neither too high nor too low. The higher the power, the faster the decay. 100% battery for one month, and 50% battery for one month. The capacity of the former will decline more if the battery is put for a month. Don't keep the battery power at 100% for a long time, this will also affect the battery life to a certain extent.

3. Avoid using at high temperature or extremely low temperature. Charging at high temperature and low temperature will cause great damage to the lithium battery of the mobile phone. A high temperature may cause the battery to explode, and a low temperature will also have a great impact on battery life.

4. Avoid the long-term battery of your mobile phone is in a dead state. If the battery is in a dead state for a long time, it is very likely that your mobile phone will no longer be able to turn on.

5. Use the original mobile phone charger, check the service life and shelf life of the battery, and replace the battery in time.

The best way to maintain the lithium-ion battery is to use it lightly, discharge quickly and charge quickly, avoid over-discharging and overcharging, maintain the power of the mobile phone at a low power state of 30%-50%, and reduce the "resting time in a high power state". There is nothing to plug the charging cable into the phone to charge. In this case, the phone will draw power from the outside, which is equivalent to reducing the number of discharge cycles.

The above is about the correct use of lithium-ion batteries for mobile phones. I hope it will be helpful to everyone. Chung Pak specializes in providing various lithium-ion batteries and looks forward to your visit and consultation.
