How to prevent damage to the battery?

There is a saying that when a new battery or a new mobile phone is charged for the first time, the battery must be used up and then fully charged. This cycle is three times, and the mobile phone must be fully charged before being unplugged. In fact, neither of these two statements Yes, the current smart phones use lithium batteries, and lithium batteries have no memory effect. Dissatisfied or not used up will not affect the life and capacity. There is also no saying that the battery should be discharged during the first charge. The following are several states to prevent damage to the battery: 1. To prevent excessive discharge, try not to use the mobile phone below 20% of the power, especially do not use the mobile phone below 5% of the power, which will cause irreversible damage to the battery. 2. Prevent over-charging. Over-discharge and over-charge will cause great damage to the lithium battery of the mobile phone. However, the current smart phone generally has circuit protection, and the battery will not continue to be charged after it is fully charged. 3. Prevent use at high or very low temperatures. Charging at high and low temperatures will cause great damage to the lithium battery of the mobile phone. High temperature may cause the battery to explode, and low temperature will also have a great impact on battery life. 4. Prevent your mobile phone battery from being in a non-powered state for a long time. If the battery is in a non-powered state for a long time, it is very likely that your mobile phone will no longer be able to turn on. 5. The ideal state of the lithium battery is when the battery is 40% left. At this time, the voltage of the battery will not be too high or too low. The higher the battery, the faster the decline. 100% of the battery will be stored for one month, and 50% % Of the battery is left for a month, and the former has a greater capacity decline. Do not maintain the battery power at 100% for a long time, as this will affect the battery life to a certain extent.
