How to maintain the mobile phone battery?

1.  Fully charged to use each time, reduce the number of times to charge, improve battery life.

2.  Don’t need to discharge the battery completely, usually less than 10% of the power needs to be charged.

3, Use the original charger to charge, the original charger is specially designed for cell phones, can provide stable current and voltage, help to protect the battery life.

Don't use universal charger to charge, if we use non-original charger or copied charger, it may cause unstable current and voltage, thus depleting the battery life.

4, Don't use your mobile phone during the charging process.

5, Don't overcharge, stop continuing to charge after the battery is full. Research shows that the battery power to reach more than 90%, the charging speed will become slower, if the charge to 100% power, the battery will be in a kind of “overcharging” state, which will deplete the battery life. Therefore, we should try to control the charge at about 90%, which can effectively extend the battery life.

According to experimental results, the life of lithium batteries is with the increase in the number of times with the charging and continuous decay, the general lithium battery charging times is 2000-3000 times.

Cycle is to use, we are using the battery, concerned about the time of use, in order to calculate the rechargeable battery in the end can be used for how long such a performance, the definition of the number of cycles. The actual user use is very varied, because the conditions of different tests are not comparable, to have a comparison must standardize the definition of the battery cycle life.

National standard lithium battery cycle life test conditions and requirements: in the ambient temperature of 20 ℃ ± 5 ℃ conditions, with 1C charging, when the battery terminal voltage reaches the charging limit voltage 4.2V, change to constant voltage charging, until the charging current is less than or equal to 1/20C, stop charging, set aside for 0.5h ~ 1h, and then discharge to the termination voltage of 2.75V at a current of 1C, the end of discharge, set aside for 0.5h ~ 1h, then the next charge and discharge cycle, until two consecutive discharge time is less than 36min, then the life is considered to be terminated. 0.5h~1h, and then carry out the next charging and discharging cycle until two consecutive discharging time is less than 36min, then the life is considered to be terminated, and the number of cycles must be more than 300 times.
