How to increase lifetime of mobile phone lithium battery ?

How to charge the phone? This is a hot topic in recent years. Regardless of number of teachings and more instructions on the Internet, we can always hear a lot of "wrong" mobile phone charging way. And these way are nothing more than "the phone must be charged for eight hours before use" "the phone must be used completely without power to use" "the phone will be unplugged when it is 90% charged" and so on.

Today, you must know about your mobile phone charging three things. Just follow these three instructions to charge your appliances and you will have a longer battery life than others.

1. Lithium battery has no memory effect, and excessive discharge will only accelerate it.

It can be said "the mobile phone has to run out of electricity and recharge" is the first place in the list of misconceptions. Why is there such a wrong idea? In fact, "the battery has a memory effect. If it is not finished, the battery will break the battery." This is the characteristic of a nickel-metal hydride rechargeable battery. This mainstream rechargeable battery before the lithium battery is widely used must wait for the battery to run out. Charging, otherwise the battery will used less and less. Now, smart phones, tablets, laptops, digital cameras, mobile power supplies and other products commonly used as lithium-ion batteries. This type of battery has a very different characteristic from nickel-metal hydride batteries: it has no memory effect and cannot be over-discharged.

The service life of a lithium polymer battery is calculated based on the "number of charge cycles", that is, the number of times "0~100%" is charged. Simply put, if a lithium battery has 1000 cycles, then theoretically, if it repeated one thousand times from 100% to 0% and then 0% to 0%, the battery is almost the same. End of life is dead! However, in fact, the physical characteristics of the lithium battery cause damage to the battery itself when it is over-discharged. If you often use the battery to 0% to charge, then the battery will not control whether you have used it many times, but directly killed early!

Therefore, the first limitation of lithium battery use is that you should never use the battery until it completely discharged. It is best to fill the battery when you can charge it, so that the battery can make you use it for a long time. ~ If you often go out for a whole day, there is no way to charge, often dragging home, the battery is less than 10% to charge, then I suggest you buy a mobile power with you, don't always let your battery In the state of ultra-low power 喔~

2, charge full, do not rush to pull, you must leave and then unplug

The second concept of charging error is "to charge up to 100% to be unplugged immediately." In fact, whether it is a mobile phone or a computer, the manufacturer will design an anti-overcharge mechanism. When the battery is full, it will automatically switch to the power supply-to-supply power to the computer or mobile phone. For example, the above picture can see when the computer battery is charged. When you charge 100%, your MacBookPro will automatically switch to the power supply until the battery reaches 95%. In addition, if you pay attention to iOS6 (if you still have?), the battery display in the upper right corner will also become the plug pattern after fully charged. This is the prompt for the phone to switch to the external power supply.

Therefore, if you are fully charged, you do not need to rush out of the power supply. When you must leave the place where you can charge, you can unplug it. Maybe someone will question, "Is it really okay to plug in the power?" about this... unless you charge the phone for a week, please believe that the electrical appliance manufacturer's ability to prevent overcharge mechanism design, do not put yourself Made nervous!

3, two weeks to make the battery power less than 20%, to maintain battery health

If you change your charging habits smoothly after reading the above instructions and follow the instructions above to protect the battery, then your battery has taken a big step towards "longevity battery"! However, here you need to do one more thing: keep the battery level below 20% every two weeks to keep the battery healthy. First, we must know that the lithium battery is a very troublesome battery. If you let it charge and discharge, it will hang up early; always let it discharge to 0% will also hang early; even if you have not let it discharge it will be early Hang up!

Due to its physical characteristics, lithium batteries cause the battery to die early if it does not fully discharge and activate the internal storage structure for a long time. However, if you let him discharge every day, it will also cause the battery to die. Therefore, in order to solve this contradiction, the best way is to let the battery be less than 20% every two weeks (do not use 0%) After recharging, you can maintain the health of the battery well and let him stay with you for a long time!

Of course, this is mainly because you often plug in the electrical appliances to have such a demand. If you discharge the battery below 20% every day, then you do not have to do this extra work.

To what extent is the battery "dead"?

In fact, two simple steps can made clear:

The first is that the lithium battery will expand after it dies. Please note that this is not an explosion. This is just a mechanism to remind you that the battery has broken. If your iPhone or other device suddenly becomes "fat", please change the battery quickly!

Second, if the battery does not get fat and your phone obviously has less power stored than before, you should get your battery repaired if not your app is causing power consumption.
