The high and low power states have adverse effects on the life of lithium battery. Most of the number of recharges marked on appliances or batteries sold is based on a baseline of 80 per cent discharge. Experiments have shown that for some laptop lithium batteries, the battery voltage is usually 0.1v higher than the standard voltage, that is, from 4.1v to 4.2v, the battery life will be halved, and then the life will be improved by 0.1v, which will reduce the original life by 1/3. The more fully you charge the battery, the more it will burn. A long period of low or no power increases the resistance to electronic movement within the battery, resulting in a smaller capacity. A lithium battery should be in the middle of the battery, which has the longest battery life.
