2. Avoid overcharging. Overcharging will cause great damage to the lithium battery of mobile phone. However, at present, smart phones generally have circuit protection, and will not continue to charge the battery after being fully charged.
3. The ideal state of lithium battery is that the battery power is 40%. At this time, the battery voltage will not be too high or too low. The higher the battery charge, the faster it drops. If 100% battery is left for one month, the capacity of the former will decrease even more. Don't keep the battery charge at 100% for a long time, which will also affect the battery life to some extent.
4. Avoid using at high temperature or extremely low temperature. Both high-temperature and low-temperature charging will cause great damage to mobile phone lithium batteries. High temperature may lead to battery explosion, while low temperature will also have a great impact on battery life.
5. Avoid the long-term dead state of the mobile phone battery. How to keep the battery dead for a long time, it is very likely that your mobile phone will never be turned on again.
6. Use the original mobile phone charger, check the service life and shelf life of the battery and replace the battery in time.
7. The best maintenance method of lithium-ion battery is to use it lightly, discharge it quickly and charge it quickly to avoid overcharging, keep the battery capacity of mobile phone at a low state of 30%-50%, and reduce the "standing time in high state". If nothing happens, plug the charging cable into the mobile phone to charge it. In this case, the mobile phone will take power from the outside, which is equivalent to reducing the number of discharge cycles.
