What are the correct charging and using methods for mobile phone batteries?

1. Whether used or not, lithium-ion batteries have a shelf life of 3 years, and they will decay quickly after three years. The other is fullchargecycle. I won’t explain it any more. It decays quickly after about 400-500 times. It depends on whether you use it for 3 years or the number of times you charge it first. 2. In addition to being afraid of low power, lithium-ion batteries are also afraid of overheating, especially when charging. If your sleeve has poor heat dissipation and heats up during charging, it is best to remove the sleeve during charging. The long-term storage method for lithium-ion batteries is to charge them to 40% and put them in the refrigerator, but remember not to freeze them. 3. Don't always wait until the power is exhausted before charging, which will speed up its loss. Lithium-ion battery has a relatively large loss when it is in low power. Long-term use of 40%-60% power can make it the longest life, but for frequently used equipment, this is impossible, but you can always keep it at 100%, which is Charge it frequently and don't pull it out after the charge. It will not overcharge, and at this time, the power is used, the battery will not waste chargecycle, so it is beneficial to extend the life. You only need to fully charge it once a month, this is to calibrate the battery ruler. 4. It can be used while charging. Some people say that using it while charging will cause slow charging. Is the battery charging while discharging? In fact, it is not. There are two circuits in the mobile phone, one to charge the battery, and the other to directly supply power to the machine through AC. Charging is slow because part of the current is used by the machine, so the charging current is small, especially when USB charging, because the current itself is very small. However, it is worth noting that low-current slow charging is the preferred charging method for lithium-ion batteries, and the small amount of heat generated in this way is more conducive to its life. In addition, do not play games or use other heavy loads while charging! The reason is not that the power consumption is large, but the same as 2, there will be a large amount of heat, thereby reducing the battery life. Generally speaking, it’s okay to send messages on the Internet, and it’s not good to hold it in your hand for a long time to make a phone call. It is recommended to use headphones. 5. Connecting to the power supply after charging will not cause any harm to the battery, because it is directly powered by the power supply, which reduces the number of charging but also helps to extend the battery life. Many people will argue that my laptop has been plugged in, and the battery will die after a year. Notebooks are different from mobile phones. This situation is often caused by heat. Notebooks with poor heat dissipation have a rapid battery life, even if you don’t use them. If you always play games with the power supply, it may cause the phone to overheat due to the high heat of the power supply. This is not good. In short, as long as it is not too hot, there will be no problem. You can always plug in the power before going out. [Personally think that safety is the first priority, and someone is the best to take care of it]. 6. (To be discussed) It is not always good to charge when the battery is higher than 90% but lower than 100%, that is, it is always toppingoff. Thinkpad notebooks have a mechanism that keeps the battery from charging at 90% or more. If the mobile phone also has a charging switch, we can safely use external electricity for a long time. There is no problem if the battery continues to be fully charged at 20%-80%. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
