Therefore, it is best to slow down the decline of battery health as much as possible. Because of the characteristics of lithium battery, we can't keep the health of the battery from declining at all, but we can slow down the decline of battery health as much as possible through good charging habits. To stop loss in time, we only need to do the following four steps.
1. Don't wait until there is no power, but charge it while using it.
According to Apple's official statement, the core factor affecting the life of iPhone battery is "the increase of battery chemical age". It should be noted that although Apple is talking about the "chemical age", it is actually not calculated in years, but in cycles. A cycle refers to a cycle from 0 to 100%, that is, the number of charge and discharge cycles.
Apple's standard for this is that when the charging cycle reaches 500 times, the battery can maintain at most 80% of its initial capacity. If your iPhone battery is less than 80% healthy during the warranty period, you can apply for a free battery replacement at Apple's official after-sales service office.
2. Turn on the function of optimizing battery charging.
In Apple's official document, there is a saying: fast charging is convenient, and slow charging guarantees life.
Some foreign institutions have done experiments, charging the same new iphone with 5w, 18w and 20w chargers for two months respectively. Finally, it is found that only 5w iPhone battery is kept at 100%, and frequent use of fast charge is easier to shorten battery life. The existence of trickle charging is quite necessary, which is also the significance of optimizing the battery charging function.
3. Don't charge in an overheated or supercooled environment, and try to avoid charging while playing.
The working temperature of lithium battery performance of mobile phones and other electronic equipment is 0~40℃. The performance of lithium batteries below 0℃ will decrease, and the capacity of batteries above 35℃ will be lost.
In this regard, Apple officially mentioned that the best working environment of Apple equipment is the ideal temperature range between 16℃ and 22℃. In addition, Apple also stressed: "When using a mobile phone in a very cold environment, the use time of the mobile phone will be reduced, and the battery power will soon be exhausted, but this situation is only temporary. When the battery temperature returns to the normal working range, its performance will also return to normal. "
4. Try to use the original Apple charger when charging.
In the news, we can always see accidents in which mobile phones catch fire while charging, and most of these accidents are due to the use of inferior third-party chargers and the lack of corresponding safety mechanisms, which are very prone to the risk of overshoot, overheating or short circuit.
