It is recommended to use the official standard charger to charge the battery to ensure that the charging voltage is stable and meets the standard.
2. In theory, the battery power is maintained in the middle range of the power for a long time (about 50%, such as 30%-70%), which is more helpful to extend the battery life, so: it is recommended to unplug the mobile phone after it is fully charged, and the mobile phone is in a state of high power for a long time, which will cause the loss of the battery to accelerate.
Try to avoid waiting until the battery power is less than 20% before charging the battery, excessive discharge will cause the loss of the battery to accelerate. Can be used with the charge, to extend the battery life. It is recommended not to leave the phone idle for a long time, and the battery should be fully charged from time to time. If the mobile phone is not used or charged for a long time, the battery power will be completely consumed, which will lead to abnormal charging or no charging.
Use as you go is right, the minimum is not less than 20.
