Secrets of lithium battery maintenance methods

Lithium battery maintenance methods are revealed, you should know these devices, including iPhone, ipodtouch is now more and more we use, but I believe that many people have battery problems, and tips on how to maintain the battery are also everywhere. If necessary, keep the battery power naturally and completely shut down. Charging, you can’t use the machine to charge, otherwise it will damage the battery life, and it will be more outspoken after flash charging 100%. The line will be dizzying for about an hour. For example, you can find some maintenance software that uses the battery on the Internet. The trickle charge made me dizzy. Does all this make sense? Does battery maintenance software really work? Today the author is a person who walks into science. The iPhone uses a lithium polymer battery, which is the first answer to the statement that the battery must be fully maintained until it is naturally turned off and recharged. The controversy started from the service life of the Ni-MH battery. During the use of the Ni-MH battery, it is assumed that the charge is not fully put in to start the charge, and the next time it is discharged, the charge cannot be fully released. For example, a nickel-cadmium battery can only release 80% of its power before charging, and it can only release 80% of its power after charging. This phenomenon is called the recall effect. At this time, in order to maintain the life of the battery, it is recommended that the battery is fully discharged before recharging. However, lithium polymer batteries have no recall effect. In addition, the iPhone manual clearly stipulates that the battery should not be left in a state of lack of power for a long time, because over-discharge will result in reduced ion activity, reduced capacity, and shortened life. Therefore, it is unreasonable to say that the iPhone must maintain battery power before the battery is completely disconnected and charged. Apple’s instruction manual tells you that your battery will not run out without the recall effect. Can the battery be charged with any power? The answer is yes, but the author also sees from the online Sanyo cycle life test statement that the battery voltage is too high or Too low for a long time will damage the battery life. Generally speaking, it is not recommended to use less than 20% of the battery. Try to keep the battery at more than 20% when charging. Does it make sense to say 100% charge and then charge for another hour or so? Here is the concept of fast charge and full charge. The charging stage of lithium polymer battery is divided into two stages. In the first stage, the charging capacity is 80% and it will be completed in about two hours. This stage is called the fast charging stage. In the second phase, the falling current continues to compensate for the type of charging until the end of the full charge after about 4 hours. In the following two pictures, we can clearly see the difference between these two processes. Iphone will flash 100% when the fast charging ends. In fact, about 20% of the capacity demand is full, so it is reasonable to say that it will flash 100% and charge it for about an hour. And what is truly fully charged is that 100% of the case strip on the iPhone will become a symbol of the plug. Some so-called secrets are not scientifically based, and iPhone players are also a little worried when charging, because charging and playing with the mobile phone has always done a lot of damage to the behavior of the battery. This statement depends on the situation. When charging, the current is divided into two ways. One way is used as a mobile phone for normal operation, and the other way is used as a battery for charging. There is no problem when using the mobile phone when it is connected to an external power source. However, if you just read web pages, send text messages, such as behaviors, to satisfy the operation of large software, such as large 3D games, when the temperature of the mobile phone is increased, this is a violation of Apple's clarification book that says to charge and keep the battery at room temperature or close to room temperature. Pay attention, so make sure that the battery temperature is too high, and there is no problem with payphones without playing. Of course, this is only a theoretical problem, and it is usually recommended that we do not charge for use. Speaking of this, I also use it to say that many people like to use mobile phones for repairs. The author does not recommend using them. The most important reason is that charging will inhibit the heat dissipation of the machine. In addition, the mobile phone repair cover is not completely sealed, and solid particles enter the cover after repair. A shorter conflict with the mobile phone center scratched the machine.
