How to use the mobile phone lithium battery correctly

The newly purchased mobile phone needs to use the electricity in the mobile phone first. Then charge it, and it needs to be operated 3-4 times repeatedly, which is called so-called activation. It used to be possible in the past, but now the phones are all lithium batteries and do not need to be activated at all.

The newly purchased mobile phone battery does not need to be charged for 12 hours for the first time, but it is best to carry out the full charge and discharge process for 3~5 hours. The full charge is normal charging to 100%. The full release is when the mobile phone uses the low battery reminder.

Because the battery is subjected to electrolyte filling, chemical formation, charge and discharge, and volumetric process before leaving the factory, the battery is activated, but it takes less than one month after delivery to reach the user's hands. The effect of the discharge, the battery material is passivated, and then the battery can be activated by full charge and discharge.

The saying that "the first three charges should be charged for more than 12 hours" is for the rechargeable battery of the 1990s. At that time, the nickel-cadmium battery had a memory effect and needed to be fully charged to ensure battery capacity. The lithium-ion battery is used on the mobile phone. It has no memory effect. It can be filled in 2-3 hours, and full is enough.

If the charge and discharge of the new battery can reach 12 hours or more before, it will cause great damage to the battery, which may cause the battery to bulge or even burn. Fortunately, both the mobile phone and the charger have protection circuits. When the battery is charged to 100%, it will automatically power off, and it will not continue to be charged when plugged into the charger.

However, it is better to unplug the charger at this time, in case the charger protection circuit has a problem, the battery is overcharged, causing serious damage to the battery material, affecting the capacity and life of the battery. Usually, the charging method described in the mobile phone manual is a standard charging method suitable for the mobile phone.

The correct use of mobile phone lithium battery:

1. Avoid transitional discharge. Try not to use the mobile phone below 20% of the power. In particular, do not use the mobile phone below 5% of the power, which will cause irreversible damage to the battery.

2, to avoid transitional charging, over-discharge will cause great damage to the lithium battery of the phone, but currently smart phones generally have circuit protection, will not continue to charge the battery after full charge.

The ideal state of the lithium battery is when the power is 40% left. At this time, the voltage of the battery will not be too high or too low. The higher the power, the faster the decline, 100% of the battery is discharged for one month, and 50%. The battery is released for a month, and the capacity of the former is declining more. Do not keep the battery's power at 100% for a long time, which will affect the battery life to a certain extent.

3, to avoid use at high temperature or very low temperature, charging at high temperature and low temperature will cause great damage to the lithium battery of the mobile phone, high temperature may cause the battery to explode, and low temperature will also have a great impact on battery life.

4, to avoid your mobile phone battery is in a state of no power for a long time, how long battery is in a state of no power, it is likely that your mobile phone can no longer boot.

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

The best maintenance method for lithium-ion batteries is light use, fast release and fast charge, avoid over-discharge and over-charge, maintain the mobile phone's power level at 30%-50% low battery state, and reduce the "station time under high battery state". Often plug the charging cable into the phone to charge. In this case, the phone will take power from the outside, which is equivalent to reducing the number of discharge cycles.
