Three-point charging tips to improve your battery life

These erroneous charging teachings have not only appeared in mobile phone stores, electrical stores, Apple stores, and even television news has seen similar error charging teaching. So how do you charge your phone and how to maintain it? Today, I'm going to sort out three things you must know about charging your phone. Just follow these three instructions to charge your appliances, and you can make your phone battery have a longer life than others!

Note: Sources include Apple's official website, battery manufacturer instructions, and have been verified by me for many years.

1. The lithium battery has no memory effect, and excessive discharge will accelerate it.

According to my personal experience, "mobile phones need to run out of electricity and recharge" can be said to be the first place in the list of misconceptions. Why is there such a wrong idea? In fact, "the battery has a memory effect. If you don't use it, the battery will break the battery." This is a characteristic of a nickel-metal hydride rechargeable battery. This mainstream rechargeable battery before the lithium battery is widely used does have to wait for the battery to run out. You can charge, otherwise the battery will be used less and less.

But now, smart phones, tablets, notebooks, digital cameras, mobile power and other products are used in lithium polymer batteries commonly known as "lithium batteries." This battery has a very different characteristic from nickel-metal hydride batteries: there is no memory effect and it 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 to 100%" is charged.

Simply put, if a lithium battery has 1000 cycles of life, then theoretically as long as "100% used to 0% and then 0% back to 100%" repeated 1000 times, then this battery is almost End of life is dead! But in fact, the physical characteristics of the lithium battery cause it to 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 to completely charge it. 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. Hey! If you often go out for a whole day, you can't charge it, often drag it home, and the battery is less than 10% to charge. Then I suggest you buy a mobile power supply, don't always let your battery be in Ultra low battery status!

Second, the charge is 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". The origin of this statement is not personal to me, but we do not need to delve into the source of misconceptions. 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 be seen when the computer battery is charged. When you charge 100%, your MacBook Pro will automatically switch to the power supply until the battery reaches 95%. And if you pay attention to iOS (if you still have), the battery display in the upper right corner will become the plug pattern after charging, which is the prompt for the phone to switch to the external power supply.

Therefore, if you are fully charged, you don't need to rush out of the power supply. When you have to leave the place where you can charge, you can unplug it. Some people may ask, "Is it really okay to plug in the power?", I think that unless you will charge your phone for a week, please believe that the ability of electrical manufacturers to prevent overcharge mechanism design, do not I am nervous!

Three, two weeks to make the battery power less than 40% once, 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"! But here you need to do one more thing: keep the battery level below 40% every two weeks to keep the battery healthy. First of all, we must know that the lithium battery is a very awkward battery. If you let him charge and discharge, he will hung up early, keep discharging it to 0%, and will hung up early. Even you will not let the discharge go 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. But if you let him discharge every day, it will also make the battery go to death, so in order to solve this contradiction, the best way is to make the battery less than 40% every two weeks (30% also, do not use 0 % can be recharged after the battery, you can maintain the health of the battery, let him stay with you for a long time!

Of course, this is mainly because you often plug in the electrical equipment to have such a demand. If you discharge the battery below 40% every day, then you don't have to do this extra thing!

As for the extent to which the battery is "dead"? In fact, two simple steps can be made clear. The first is that the lithium battery will swell 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 hurry to change the battery!" Second, if the battery doesn't get fat, but your phone obviously has less power stored than before, then if you are still excluding electricity because your app is causing a sharp power consumption, it is recommended that you hurry. Send it for repair!
