How to maintain the lithium battery of mobile phone
Mobile phone battery maintenance method:
1. Use fully charged each time, reduce the number of charging times and improve the battery life.
2. Do not fully discharge the battery, usually it needs to be charged when the power is less than 10%.
3. Use the original charger to charge, do not use the universal charger to charge.
4. Do not use the phone while the phone is charging.
5. Do not overcharge, stop charging after the battery is fully charged.
Yes, according to the experimental results, the life of the lithium battery is continuously attenuated with the increase of the number of charging times. Generally, the number of charging times of the lithium battery is 2000-3000 times.
Cycle is use. We are using the battery, and we care about the time of use. In order to measure the performance of how long the rechargeable battery can be used, the definition of the number of cycles is specified. Actual user usage is ever-changing, because tests with different conditions are not comparable, and the definition of cycle life must be standardized if there is a comparison.
Lithium battery cycle life test conditions and requirements specified by the national standard: under the condition of ambient temperature of 20℃±5℃, charge at 1C, when the battery terminal voltage reaches the charging limit voltage of 4.2V, change to constant voltage charging until the charging current is less than or equal to 1/20C, stop charging, leave it for 0.5h~1h, then discharge with 1C current to the end voltage of 2.75V, after discharge, leave it for 0.5h~1h, and then proceed to the next charge-discharge cycle until two consecutive discharge times If it is less than 36min, it is considered that the life is terminated, and the number of cycles must be greater than 300 times.
