How to prolong the cycle life of mobile phone lithium batteries?

How do you charge the battery? This question can be said to be the best topic in recent years. Whether there is more explanation on the teaching network, we sometimes find a lot of wrong mobile phone charging method. The content of the teaching is "The mobile phone needs to be charged for eight hours", "The mobile phone needs to fully charge before use", "90 % of the mobile phone charger will be removed from the charger" and so on.

Today, friends schedule three things about charging your phone. As long as you charge in three directions, you can make your phone battery life longer than others.

1. Lithium batteries have no memory effect. Excessive discharge will only speed it up.

It can be said that the idea of "mobile phone power outage" is wrong again. Why would you think that? "The battery memory effect, which can damage the battery if it is not charged," is one of the characteristics of nickel-metal hydride charging batteries. Before lithium batteries are widely used, mainstream rechargeable batteries are really waiting until the battery can be charged. The capacity of the completed or battery will be less. However, the products used today are generally referred to as "lithium batteries" lithium polymer batteries, such as smartphones, tablets, laptops, digital cameras, and mobile power supplies. The battery has a distinct feature from nickel-metal hydride batteries: no memory effect and no excessive discharge.

The "charging cycle" of the lithium polymer battery is calculated based on the service life of "0 to 100 %" charging time. Simply put, if a lithium-ion battery has a life cycle of 1,000 cycles, theoretically, as long as "charging from 0 % to 100 %" is repeated a thousand times, the battery will soon die! But in fact, the physical properties of lithium-ion batteries can cause excessive discharge damage to the battery itself. If the battery is often recharged by 0 %, the battery will not care that you do not have so many cycles and will kill it early!

First use limits, so lithium batteries will never be completely without power to charge batteries, which is best if you can charge when the battery is full. Try to keep the battery running for a long time. If you often go out and can't charge all day, you often have to go home and the battery charges less than 10 %, so you might as well buy a live power source. Don't always keep you in a low-power battery state.

2, charging do not need to quit in a hurry, then quit can

When the charge for wrong ideas comes in second place, it will soon drop the charge to 100 %. In fact, whether it is a mobile phone or a computer, the manufacturer will design a high-charging mechanism. When the battery automatically switches to the computer or the mobile phone power supply, the above picture can be seen. For example, when the computer battery is charged to 100 % MacBook, it will automatically switch to the power supply., This will not be maintained until the battery reaches 95 %. If you're interested in iOS 6(if you have more? ) After charging in the upper right corner, the power display becomes the plug design, which is the power supply for the mobile phone to switch to the external power supply.

Therefore, charging does not need to rush to unplug the power supply. It can wait until you leave the place where the charging can be pulled out again. One might wonder, "Is electricity really important? ", about this ... unless you can charge your mobile phone within a week, trust the electronics manufacturer to prevent the mechanism design of charging, do not be nervous!

Three or two weeks is less than 20 % of the battery, maintaining cell health

If you have successfully changed the charging habits in the above teaching and protected the battery according to the above instructions, your battery is an important step toward the "long-life battery"! But here, you need to do one thing: get the battery less than 20 % every two weeks to keep the battery healthy. First of all, we want to know that lithium batteries are a very troublesome battery, you keep it charging and discharging it will hang up early; Even if you don't let it discharge, it will hang up early!

Because of its own physical properties, lithium batteries can cause batteries to die prematurely if they are not fully discharged for a long period of time and activate the internal storage structure. But if you let him discharge electricity every day, it will also kill the battery, so to solve the problem, the best way to solve the problem is to let the battery less than 20 %(0 %) of the battery every two weeks without rechargeable batteries, which is very good for battery health. let him long time to accompany you!

Of course, if the Lord do you often get with electrical appliances are not only have such demand, if you will discharge the battery to less than 20% the following everyday, so don't have to do the unnecessary things.

Battery to what extent is the "death"?

Actually simple two step can understand:

The first is the lithium battery will swell after die, please note that this is not the explosion, it is just remind you battery has broken mechanism, if your iPhone or other device suddenly "fat", please go to change batteries!

Secondly, if the battery is not bigger, your phone obviously has less electricity than before. If it is not your APP consumes the electricity, I suggest you to send it to repair as soon as possible.
