Is the phone charging 20% recharged, or is it charged as long as it is available? How is it better? Let me talk about myself, I am a patient with obsessive-compulsive disorder. If the mobile phone's power is less than 50%, I will lose my sense of security. I will charge the charger. So how is it better to charge?
Everyone only knows that the mobile phone is a lithium battery, but it is accurate to say that the battery commonly used in mobile phones is a lithium polymer battery which is a polymer lithium battery.
It is also a kind of lithium ion battery. In shape, the lithium polymer battery has ultra-thin characteristics, and can be made into a battery of any shape and capacity in accordance with the needs of various products. The battery can reach a minimum thickness of 0.5mm. The most important feature is that there is no memory effect! and so:
The calculation method of lithium battery is calculated in cycles! That is to say, when the charging is 50%, it is not a charging cycle. A battery charge and discharge cycle must be formed after the entire battery has completed one cycle. This means that the lithium battery can be unplugged at any time without worrying about this problem.
Although the number of charge and discharge cycles of the battery is fixed, it is another complete charge and discharge to calculate a cycle, that is, if you charge from 20% to 70%, you actually charge only 50% of a cycle. That is, it was only half a time. Based on this theory, lithium batteries can be recharged at any time without worrying about life. Taking the iPhone's battery as an example, after completing the discharge cycle of 500 charging boxes, the power will drop to 80% of the original battery capacity.
A few points to pay attention to the charging of the phone, remember
1. Make sure that your equipment is not over-tightened, which will cause the equipment to overheat and affect battery life.
2. Try not to play mobile games while charging. Playing mobile games will generate a lot of heat, and continuous consumption will affect battery life.
3. Overcharge, do not use the unofficial inferior charging head or charging cable, the charge exceeds the rated capacity of the battery, the mobile phone generally has a protection mechanism, after the battery is fully charged, the internal circuit of the mobile phone automatically disconnects the charging circuit, or the charging head has Protection device, poor quality can not be said.
4. The battery is over-discharged, and there is no electricity to charge quickly. Usually, when the battery is too low, it will automatically shut down. But if you restart, you will find that the phone still has power to use. Automatic shutdown is a kind of protection mechanism for manufacturers of mobile phone batteries. Over-discharge of the battery will cause serious damage to the battery life. Therefore, please charge when the battery is too low.
5. Use a charger with a high power to charge the battery, which will cause damage to the battery. For example, the original mobile phone is 3.5V, but with a 5V charging head, it will cause damage to the battery.
