2. Wrap the cell phone battery close to the use limit with plastic wrap, put it in the refrigerator, freeze it for three days, and then take it out for further use. The battery will last longer than before freezing. The process of using mobile phone battery is a process of charging and discharging. When the battery is placed in a low temperature environment, the microstructure of the lithium film and electrolyte on the surface of the lithium battery leads to the internal inactivity of the battery and the reduction of leakage current, so the waiting time of the mobile phone will increase after charging.
3. Wiping the metal contact surface between the mobile phone battery and the mobile phone with an eraser can make the use of the mobile phone battery better.
Extended data:
1. It doesn't take 12 hours to charge the mobile phone for the first time. When the mobile phone screen shows that the battery is fully charged, there is no need to charge it. It's best to fill it while using it. It is best not to use universal charger, because the current of universal charger is unstable and the quality is uneven. Try to use the original charger.
2. Lithium battery has no memory effect, so there is no need to ensure that it is charged and discharged every time. Completely exhausting the power of the mobile phone has a serious impact on battery life.
3. The deep charge and discharge under the control of the protection circuit can be done once in a while to correct the battery's electricity statistics, that is, the mobile phone will be recharged after it is exhausted, but this will not improve the actual capacity of the battery.
4, don't expose the battery to high temperature or cold environment, like dog days, don't put the phone in the sun, exposed to the scorching sun; Or take it to an air-conditioned room and put it in a place where the cold wind blows directly.
5. Don't play with your mobile phone while charging. The mobile phone generates too much heat when charging, which is easy to cause battery damage.
