Classification of battery life decay mechanism

The decay mechanism of battery life is mainly divided into two categories: excellent species of cyclic decay. Think of the battery as a tube, pumping up when charging, and pumping down when discharging. Up and down without a stroke is a complete cycle, half of the stroke is half a cycle, and the battery with a long stroke is broken. This is the so-called cycle decay. The cyclic decay is the first type of charge decay, which is the upward stroke in the attack. The second is static attenuation. In other words, if you leave the battery quietly without taking it out, you will also be damaged. The rate of deterioration depends on the position of the hand, the higher the position of the hand (the higher the charge), the faster the rate of deterioration. The two decay rates are of different orders of magnitude. As far as mobile phone batteries are concerned, they consume electricity basically every day, and the damage to life caused by cyclic decay is at least an order of magnitude greater than static decay. What is our strategy? According to the philosophical common sense of the first enemy to be grasped by Marxist philosophy, the first thing to do is to minimize the decline in circulation and reduce the depth and quantity of retouching; the next step is to reduce static attenuation, that is, to reduce the height of. After describing the above principles, let us return to the unused situation, such as 50% charging and 10% charging. What we want to express is that a static decay rate of 10% is slower than 50%. Regarding the situation of most people using mobile phones, when they are faced with the choice whether I want my phone’s battery power to be 50% or 10%, they usually encounter the following situation: Case1: My phone has 50% battery power, but I Still decided to use 10% before charging, even if the charging cable is nearby. This is equivalent to adding cyclic attenuation, while reducing static attenuation is due to small losses. Although the discharge from 50% to 10% is not attenuated, it must be recharged after the discharge is discharged, and it will not run away. Case 2: My phone is charged 10%, but I don't plan to charge it. I plan to charge it to 50% or 100% two hours before leaving home. This strategy does reduce static decay without adding cyclic decay and optimize battery life. This is the situation I mentioned in my initial response to the best strategy. The realization of this optimal strategy depends on the smart charger. In order to protect the mobile phone battery whose cost is only a few tens of yuan, adding a smart charger is unreasonable, and customers do not like it in the market. So this strategy is usually not feasible. Case3: My phone has 100% battery power, and I plan to use 10% today. I plan to use 10% all at once instead of 55% and then 55%. Of course, using 10% in one breath is better than using 55% and then using 55%. But the value of this advantage is that it gives up the opportunity to charge halfway and adds the risk of running out of power. The premise of this strategy is that I am 100% sure that I only used 90% of the electricity today, and nothing more. In fact, this problem is similar to the mileage anxiety of electric vehicles, which is one of the important obstacles to expanding the scope of electric vehicles. For the average mobile phone user, this strategy is usually not feasible. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
