Factors affecting the durable of TWS headset charging Pogo pins
Overcharge and over-discharge, the normal operating voltage range of lithium batteries is between 3.6V and 4.2V. Use below 3.6V or above 4.2V (the charger usually needs 5V, after passing through the current-limiting circuit and the battery's own load, the voltage will become lower than 4.2V) charging will cause the battery to heat up and affect its service life. However, current batteries have an overcharge protection circuit, as long as they are not too copycat chargers, there is usually no problem.
High current and short circuit, long-term continuous use, if you often talk or listen to music for a long time, the battery will heat up too much current, and long-term use will affect its normal service life, so it is best not to use it frequently. Use it for a long time, even if you stop using it for a few minutes. This will also be better for battery performance.
3. Low battery for a long time. If the battery is not used for a long time, let the battery stay at a voltage below 3.6V, or use too much to discharge the battery until the battery is damaged. Many batteries are damaged or the use time after charging is increasing. The shorter is mostly because of this reason.
