How to maintain the mobile phone battery to make it better?

Introduction to the correct use of mobile phone lithium battery: First, the charging time should not exceed 12 hours. For the "activation" of lithium batteries, there are many sayings: the charging time must exceed 12 hours, and it must be repeated three times before the battery can be activated. This statement that "the first three charges need to be charged 12 hours or more" is obviously a continuation from the statement of nickel batteries (such as nickel cadmium and nickel hydrogen), so this statement can be said to be misinformed from the beginning. It is best to charge according to the standard time and method, especially not more than 12 hours. Usually, the charging method introduced in the mobile phone manual is the standard charging method suitable for this mobile phone. Second, put the lithium battery in a cool place. High state of charge and rising temperature will accelerate the decrease of battery capacity. If possible, try to charge the battery to 40% and place it in a cool place, so that the battery's own protection circuit can work in a long storage period. If the battery is fully charged and left at high temperature, it will cause great damage to the battery. (So when we use a fixed power supply, the battery is in Wally state at this time, and the temperature is generally between 25-30℃, which will damage the battery and lead to its capacity decline). Don't expose the battery to high temperature or cold places, such as dog days, and don't expose the mobile phone to the sun; Or take it to an air-conditioned room and put it in a place where the cold wind blows directly. Third, avoid charging the battery after all the batteries are used up. The life of a battery depends on the number of times of repeated charging and discharging. The lithium battery can be continuously charged and discharged for about 500 times, after which the performance of the battery will be greatly weakened. We should try to avoid discharging all the remaining power in the battery before charging, otherwise, with the increase of charging times, the performance of the battery will gradually weaken and the standby time of the battery will be difficult to decrease. Fourth, use a special charger. Special charger must be selected for lithium-ion batteries, otherwise it may not reach saturation state and affect performance. Do not leave it on the charger for more than 12 hours after charging. When not used for a long time, the battery should be separated from the mobile phone. It is best to use the original factory or reputable brand charger.
