What affects the life of the charging pin of TWS?
1. Overcharge and over-discharge, the normal range of lithium battery operating voltage is between 3.6 and 4.2V. Use lower than 3.6V or higher than 4.2V (chargers usually need 5V. After passing through the current limiting circuit and the load of the battery itself, the voltage will become lower than 4.2V). Charging will cause the battery to heat up and affect its service life. But now the battery has an overcharge protection circuit, as long as the charger is not too fake, there is usually no problem.
2. High current and short circuit, continuous use for a long time, if you often talk or listen to songs for a long time, the current of the battery will be too hot, and long-term use will affect its normal service life, so it is better not to use it frequently Use for a long time, even if you stop for a few minutes and then use it again. This will also be better for battery performance.
3. Long-term low-power state, if it will not be used for a long time, the battery will be kept at a voltage below 3.6V, or the battery will be damaged if it is used too much. Many batteries are damaged or the use time after charging is getting longer and longer. Shorter is mostly for this reason.
