Many people have asked this question, and in the final analysis, they are worried about their bad charging habits, affecting the efficiency of the battery, resulting in a series of costs such as replacing the battery.
Today in response to this problem to give you a solution, in fact, this problem is very simple, just like asking people to eat when they are hungry, some people are hungry before eating, some people are to eat, some people are in a good mood to eat, there are many ways to eat, and finally reflected in some people have a good stomach, some people have a bad stomach, but the battery is not the same as people eat. The battery is outside, I personally feel that you don't have to care about how much power the phone uses to charge, just a little bit, when you want to charge it.
If you have to ask what kind of charging habits are the best for battery maintenance, my answer is to use with charge, try to make the power always between 20 and 80 cycles, not less than 20 and not higher than 80, such charging habits are the best. Just like people eat, never be hungry, do not support, not full and not hungry state is the best.
In fact, people pay attention to how much electricity is used before charging, it is better to pay attention to what charger they are using to charge their mobile phones. The use of original chargers or certified genuine chargers is the best, especially car charging, be sure to buy a good, because the use of inferior chargers lead to charging IC damage, the cost of replacing the maintenance of the motherboard is much higher than the cost of replacing the mobile phone battery.
Another special mention, do not charge while playing games, this situation will lead to serious heat of the phone, the battery overheating or too cold will affect the efficiency of the battery, and as for the battery to use how much charging, this problem is really not important.
01 When the phone battery is less than 20%, the phone will prompt a low battery mode, at this time you can charge.
How to charge the mobile phone is the most correct, especially now as a fast way, how to charge correctly is a lot of people are concerned about. After all, the wrong way of charging will not only speed up the loss of the mobile phone, but also be dangerous, today I will teach you how to correctly charge the mobile phone.
1. Fill it when you have time
Many people's misunderstanding of mobile phone charging is that the newly bought mobile phone must be used to be full, in fact, it is wrong, because the battery will run out of power will increase battery loss. It is recommended to charge the phone when there is time, even for a few minutes, and the phone power is maintained between 65% and 75% for a long time, and the battery life will be extended.
2. Overfilling is a mistake
A charging battery is like a balloon that has been pumping, so do not charge to a very full, and now the mobile phone on the market is mostly lithium batteries, do not need to be fully full, it is recommended that more than 95% can unplug the charger. Many people are in the habit of charging their mobile phones before going to bed, so that the battery stays in a fully charged state for a long time. It also speeds up battery depletion.
3, the use of original (regular) manufacturers of chargers
Be sure to use the original charger to charge the phone, and it is best not to often use the charger that does not match the model to charge the phone, which not only has security risks, but also may damage the charging interface of the phone.
4. Precautions
Try not to charge your phone in hot and humid conditions.
How to charge your phone correctly? Is it less than 20% to recharge or use up to recharge? As well as how to charge your phone correctly, I have listed four charging precautions for you. Please know.
30% mobile phone power to 30% recharge because the voltage is insufficient, the need for timely charging, otherwise it will lead to the consequences of voltage instability, so to protect the battery voltage normal charging
The remaining 30% is better.
Because about 30% of the time, the charging battery takes a long time, and the charging time he will self-adjust, he will ensure that you this battery is not damaged, which is now the credit of the mobile phone
I usually charge at 20
Thank you for reading!
Let's sign together and see how many of these usual mobile phone habits do you win?
Often use the phone while charging
Often look at the mobile phone at night, put the mobile phone on the bed overnight charge
Often charge below 20%
Every time you charge to 100%, you always say wait a little longer, ten more minutes
In fact, charging is like this! These behaviors have become our habitual actions. These ways may become the root cause of your battery health can not be improved. What is the best way to charge? Let's talk about it together.
Lithium battery charging time, should not be less than 20% when charging. Because the lithium battery has no memory, in the process of charging, if each time the battery power of the mobile phone is less than 20%, it will affect the health of the lithium battery of the entire mobile phone.
In the charging process, we can actually use the mobile phone, because many mobile phone manufacturers currently support charging while using. However, we do not recommend that you charge your mobile phone when using it, because there will be a certain risk factor after all, and the long-term use of the mobile phone will also cause the mobile phone to heat up, which is more serious.
In the process of charging the phone, we do not recommend charging every night until the morning of the second day. Because of this charging method, although there is the process protection of the phone, it will itself have a certain impact on the battery of the phone, because the overcharge protection it is only within a certain threshold, beyond this threshold, it will continue to charge, in this case, it will naturally have an impact on the battery health of the phone. And charging at night, it has certain security risks.
Our recommended charging interval is between 40% and 90%, and charging in this interval guarantees the battery capacity and health of the phone.
Now the mobile phone battery is the use of lithium batteries, there is no longer the use of nickel-metal hydride battery manufacturers, so there is no need to fill and release as before to maintain the battery, lithium batteries have no memory effect, with charge can be used.
Under normal circumstances, the mobile phone lithium battery is more active, so more charging will help extend the service life of the battery, it is not recommended that the battery is completely out of power and then rushed, the mobile phone power is about 20% when it can be charged, full. The second is the high power, such as 50%, 60% when you want to charge can be charged at any time, will not affect your battery life.
I'm not gonna do that, okay? I have been used to sleeping every night to charge, get up in the morning to go to work is there is electricity, other time mobile phone battery only 50 percent of I will charge... No problem was found, except for the Pingguo phone will replace the battery, other Android phones will be directly replaced with a new phone.
Nowadays, people use mobile phones for a long time every day, and the power of mobile phones is something we pay special attention to. Many people find that the longer the mobile phone is used, the less durable the power is. Although the battery itself is gradually aging, there may also be factors that do not protect the battery of the mobile phone, such as the wrong way of charging. So about the problem of mobile phone charging, how much power is the best time to charge the phone?
First of all, it is always necessary to wait until the battery of the mobile phone is completely exhausted or even forced to shut down before charging, and then plug in the charger before going to bed at night to charge the electricity overnight, which is a very bad habit, which will make the battery life of our mobile phone lower and lower. So how much power is it best to charge the phone when it is left? The answer is more than 15%, and when we charge, do not charge the phone directly to full charge, generally charging to about 90%, which can play a good role in protecting our battery.
There is also a very bad charging habit, that is, playing with the mobile phone while charging, which not only has a very bad impact on the life of the mobile phone and the battery life, but also has a security risk, while charging while playing the mobile phone will make the fuselage heating temperature becomes higher, serious and even explosion, which is not alarmist.
Now people need to use mobile phones more and more, and many times we change mobile phones are not durable mobile phone battery, so from now on, please protect our mobile phone battery, develop the correct way of charging, so that our mobile phone service life will be longer.
Their own experience of use, although sometimes can not be completely done, but at least try to do so, have the same friends please support praise!
Apple mobile phone is recommended to start charging at 20%, and lower will have an impact on the battery.
Other mobile phones generally do not need to less than 5% is OK, because some mobile phone battery activity is very poor, you use the battery is too low, will lead to a serious decline in battery life, then it is better to directly replace the battery.
Thank you for reading.
How much power is the best way to recharge a mobile phone?
The subject really do not have to tangle with this problem, the current lithium battery can be charged at any time, as long as you want to charge, you can charge at any time.
A year's battery must be used up before it can be charged, so this charging habit, as well as the cognition of the battery, is really deeply rooted.
But we should pay attention to is that do not often the battery is completely out of power and recharging, if the number of times is too frequent, it is indeed harmful to the battery.
brief summary
Don't worry about it. Whatever's convenient.
Since it is now a lithium battery, it is not recommended that the battery is running out and then charged, it can be charged at any time, and now there are tests as long as it is full, it will stop charging itself, so please rest assured.
No one please, their own small bench to move over, to charge the mobile phone is a thing that must be experienced every day, in order to the life of the phone longer, for their own safety, the phone left how much electricity is more appropriate?
Turn off the phone and recharge it? 4% prompt speaker recharge? There are many people who jump at 15%...
Did you find anything? In fact, the speed of mobile phone charging is not constant, for example, the speed of your charging in the winter will be very slow, but sometimes the charging speed is very fast, so when is the fastest charging?
First, expand knowledge, when is the fastest charging speed
For example, a battery that is almost exhausted is like a person who is extremely short of water in the desert, and once it comes into contact with water, it will steal the bell with lightning and swallow the water.
For the same reason, a battery can be charged faster when it is almost exhausted than when it is high.
But if you do that, your phone's battery will suffer.
Second, how much is left in the mobile phone charge better
In fact, modern mobile phone batteries are lithium batteries, so that the battery power is almost exhausted, and the damage to the battery is very large.
Slowly will cause slow charging, the battery does not use the problem, in addition to the mobile phone to shut down may also appear, the internal low voltage, resulting in the mobile phone can not turn on the situation.
According to the relevant personnel pointed out that if your mobile phone is always poor to use up and then charge, the battery will soon die, the most reasonable should be the mobile phone at 20% of the time to charge him.
Nowadays, the mobile phone has become an indispensable part of People's Daily life, the mobile phone will be used for a long time because of the loss of electricity and need to be charged, then, the mobile phone left how much electricity when charging better?
We all know that when the battery of the mobile phone is used to 20%, the battery capacity plate on the screen will turn into a warning red, which is the self-protection of the mobile phone inside, and the mobile phone self-defense system tells the user to pay attention to the need to replenish the battery at this time, so charging at more than 20% is an excellent choice. Because once the phone shows the prompt, it needs to be charged.
Charging a mobile phone is like eating to replenish energy when people are hungry, charging when there is too much electricity is the same as eating when people are not too hungry, too much will cause discomfort, and charging too much will also lead to a certain impact on the mobile phone battery.
Some friends also like to charge their mobile phones before they run out of battery. In this way, charging when the mobile phone runs out of battery is also extremely harmful to the performance of the mobile phone, which is equivalent to when people are extremely hungry, they will be hungry for food at this time. Similarly, charging in this case will also make the mobile phone suddenly replenish a large amount of battery, which also has certain damage to the battery of the mobile phone. And you can't always charge your phone when it runs out of battery.
Therefore, we must pay attention to the safety of mobile phone charging, the use of professional brand matching charger can also effectively protect the safety of the mobile phone, the use of inferior charger will also cause damage to the mobile phone due to some inconsistent factors and the internal structure of the mobile phone charging does not match, causing the mobile phone hot or even reduce the life of the mobile phone. Charging at the right time is also conducive to protecting the performance of the mobile phone, so using a professional charger to charge at the right time can extend the life of the charger and the mobile phone to a certain extent.
Moreover, it is best not to use the mobile phone while charging, so that the current will be released through the use of the mobile phone, if there will be electromagnetic waves generated while charging and calling, it may cause harm to the human body if you do not pay attention. There are many multilateral charging while playing mobile phones eventually cause fire and even electric shock events, in order to avoid safety risks, we must pay attention to the safety of charging.
According to scientific testing, it is the most appropriate way to charge the mobile phone before the mobile phone appears red prompt, and more than 10% is OK. Try not to charge the phone after it runs out of power and automatically shuts down. The life of the battery is limited, and the charging of the battery can be effectively supplemented to achieve the best protection for it.
1. The new phone is coming, the new battery is coming, do you need to fully charge and discharge it 3 times to activate it? ?
The answer is that this is an unnecessary step, wasting 3 cycle lives. The real activation step of the mobile phone battery is called \"formation\
2. Will a fast-charging plug reduce battery life? ?
No, you don't have to worry about it. If yes, mobile phone manufacturers will not use this thing to destroy their own products, they themselves use the corresponding battery, can adapt to high current charging, so it will not damage the battery.
3. Is the phone battery not always maintained full state ah, this is not good for the battery? ?
This is not to worry about, because it is designed for people to use, charging to 100% this is a normal function, daily function will not damage the equipment.
4. The advertising says that the battery life is 800 cycles, but recently I often from 20% to 70% to unplug, then I do not waste a lot of cycles? ?
This also belongs to worrying too much, a cycle life refers to the full capacity cycle once, then you only cycle 0.5 times the capacity at a time, which is equivalent to you only spend half a life cycle.
When a product is completed, listed, and you can buy it, the life of the lithium battery inside is difficult to affect, and you can't touch it at all. Many people may not have this knowledge, you can usually share with friends.
Electricity and energy
Next, I want to say a little more in-depth, that is, in the case of no protection chip, what is the capacity and cycle of a battery?
Let's first talk about a parameter that has the most relationship with battery life - energy.
Many students say ah, no, I see mobile phone advertisements are said to be 3000mAh power, 5000mAh large power, how do you not say electricity, and say energy?
The essential reason is that because the battery of different mobile phone brands is the same in voltage, and how long can the mobile phone last, although the determining factor is electric energy, what does the electric energy look like from the microscopic point of view?
It's a single electron moving at a certain speed in one direction, so an electron has an energy. If you add all the electrons together, that's the total amount of energy.
So what does the amount of electricity correspond to in that microscopic process?
It's how many electrons can be added together.
And what does the voltage correspond to?
The voltage corresponds to the speed of each electron in this process, but because now all mobile phone batteries are mostly the same type, so the speed of the electrons running in the battery is highly consistent. Since the difference is only reflected in the number of electrons, so the voltage thing we don't mention, so it forms a habit of discussion, that is, when asking how much energy of the phone, we don't say energy, but directly say electricity.
But the electricity still has most people say the unit is wrong, they say it is 3000mA electricity, 3000mA it is not the unit of electricity, must be multiplied by a time is the electricity. So do not make a low-level mistake, the unit of electricity is mAh. Some students often say that I am a liberal arts, I do not know this, but this is the second year of the school.
cellular li-ion battery
Although all kinds of mobile phones basically use the same kind of lithium battery, but the types of lithium batteries are actually very many, each type corresponds to different voltages, these voltages are mostly distributed between 3V and 4.5V, the classification is based on the chemical materials of the positive battery.
What does the cell phone battery use?
It uses a ternary material lithium battery, of which ternary refers to three elements, generally nickel, cobalt, manganese, these three elements in accordance with a certain ratio of added together. The mobile phone battery is a relatively friendly environment, the pressure is relatively low, there is no long-term extremely high temperature or extremely low temperature, there is no high current, and there will be no long-term power failure, so you can adjust the proportion of cobalt in the three elements to be higher, because you can adjust this, you can increase the energy density.
Energy density refers to the amount of energy that can be stored per unit weight, the general unit used is Wh\/kg, 1000Wh is 1 KWH of electricity.
What is 1 KWH of electricity?
That's about the amount of energy that can run an air conditioner for an hour in the summer.
The specifications of the lithium battery for the mobile phone, in terms of energy density, it is better to 200Wh\/kg, that is to say, a 10-pound lithium battery is full of electricity, you can let your home air conditioning run for 1 hour, which is the battery used on the mobile phone.
However, if in other more harsh environments, the battery is not so dense, such as the battery in electric vehicles, until now only Tesla has used this indicator, which can reach 200Wh\/kg, and other domestic electric vehicles are probably between 110 and 150. And with everyone understand the CPU performance growth law is not the same, the battery energy density increase speed is much slower than the CPU, for example, in the last 10 years, the energy density of lithium batteries in the field of commercial only increased by about 30%, but the CPU performance has been improved by 30 times.
Basic knowledge of battery capacity
What is the battery capacity?
It was determined through a series of experiments that involved a huge amount of work.
For example, if we now find three new materials with potential, called X, Y and Z, we don't know how they will behave in the positive electrode, so we will try them in the laboratory. Mix their powder well, let's mix it together in a ratio of 1:1:1, to see how it performs.
We can charge it from the most likely starting point of charging 3.0V, charging and charging, while charging, the battery voltage is constantly rising, and finally rising to 4.2V, which is the voltage we commonly use, we artificially stop charging it, at this time we already have a battery that can be regarded as charged. But we don't know how full.
Then, we design a more moderate current to discharge it, how big is this current? It can be drained in about two to three hours, and we will use this amount of current to charge.
During this discharge, the voltage is constantly lowered, down to 3.0V, and then we artificially stop and record how much energy is released this time.
This process is then repeated over and over again, from 3.0V to 4.2V each time, recording the energy released after each cycle.
Why record the energy released?
Because in a continuous cycle, something is always lost, so the final rule is that as you continue to cycle, each time you release a little less energy than the last time.
So when do we stop this cycle?
It's when we finally get to the point where we're emitting less than 80% of our energy for the first time, and then we stop. At this time, let's count again, how many charge and discharge cycles were carried out during this period of time? Let's say that the number is only 50 times, then it seems that there is a problem with our 1:1:1 material ratio, then maybe this material will be discarded, or this ratio will be discarded.
So if we count 5000 times, it means that this is still engaged, it seems that in the charge and discharge, when to stop charging, when to stop discharging, we have before the two voltage points to get a little too loose, wasting the potential of the material. So we can widen the voltage gap between these two points, not 3.0 to 4.2 just now, we now expand it to 2.8 to 4.4.
What did this change result in?
It is the same capacity of the battery, this time the recycling, can output more energy. If the adjustment is so wide, it is found that it still needs 4500 charging and discharging cycles to allow the energy released by the battery to decay to the original 80%, which means that the voltage at the starting point of the charge and discharge is still a little loose, and it can continue to expand. Let's say we go from 2.8 to 4.4 to 2.6 to 4.6, and then we loop in the same way. Cycle test run, found that this 200 cycles fell below 80%, indicating that the two voltage points set unreasonable. This is how to find its more healthy discharge starting point and charging starting point.
I just gave a virtual example, in the real world, it is estimated that no battery can achieve the wide voltage range I just said.
For example, the lithium battery we currently use in mobile phones should be charged until when the voltage stops? When should the discharge be put to let the discharge cut off?
These important parameters have been measured through a large number of experiments have been very complete, and these points are extremely critical, once there is a failure to control, such as you charge to 6V, or discharge to 1V below, the battery is scrapped on the spot. So...? The charge and discharge control of lithium batteries cannot rely on human experience to operate, and can only be realized by a special control circuit, so people do not have to worry about it at all. ?
Battery life is not a concern
After knowing the basic knowledge of these batteries, you know that to ensure the life of the battery, you need to keep it under the right pressure at all times.
For example, the iPhone battery, if you each time the power is controlled between 20% and 90% of the cycle, it is equivalent to its charge and discharge of the two voltage points to shorten the distance, battery if long-term cycle in this environment, the life is likely to increase, perhaps life is 1.5 times before it, it is not possible to say. But you always artificially control the cycle at 20% to 90%, which is equivalent to you have been using a small battery that is only 70% of the current battery, and you are not convenient to use it yourself.
In addition, there are people worried, such as my phone is not able to use the power of 0 ah, the phone has shown that only 10% of the power, is it harmful to my phone?
It also doesn't hurt because it doesn't mean the battery is dead, it just tells you that the system shows it is dead, and there is a gap between the two.
For example, the characteristics of the battery, it was originally 2.8V can not continue to discharge, but when designing the mobile phone, engineers will consider setting the protection point higher, such as setting to 3.0V, because it always has to leave some margin. In actual use, for example, this situation will occur, someone used the phone to automatically shut down, and no charge, it has been put for 1 week, at this time because the protection point is set relatively high, so it always has a certain amount of lithium ions in the negative electrode to maintain a balance, the negative electrode is those composed of carbon \"small house\
So you see, whether it is the design of the battery, the design of the system, the design of the product, we are trying to set aside as much as possible to protect the battery. So in principle, after we get the product, any action we do on the product does not touch the important parameters of the battery, all protection and Settings are taken over by the protection chip, even if there are some skills to extend the life of the battery, these skills have a price. As I said, it's very inconvenient for you to use, and it's actually equivalent to using a small battery charge.
Although the lithium battery is fragile, but also because of its fragility, there is no omission of the various functions of the protection circuit, and the things that have formed the product in the battery function, all the actions used by the user can not touch the essence of the battery. Those so-called tips on the Internet can only add inconvenience to themselves. The most practical and effective way is to use it as you like, and change the battery if you can't. Especially now, the iPhone battery replacement, memory expansion service has been very much, very secure.
Mobile phones have become an indispensable part of People's Daily life. After a long time of use, the phone will need to be charged due to power failure. So, how much power is left to charge the phone? As we all know, when the phone's power consumption reaches 20%, the battery capacity board on the screen will turn into a red alert, which is the internal self-protection of the phone. It is the phone's self-defense system that tells the user to pay attention to replenishing the phone's power consumption at this time, so charging more than 20% is a good choice, because once the phone is prompted, it needs to be charged. Charging a phone is like eating to fuel people when they are hungry. Charging when there is too much electricity is the same as eating when people are not hungry. Too much power will cause discomfort, and too much charging will also have a certain impact on the phone battery. We must pay attention to the safety of mobile phone charging. The use of professional brand matching chargers can also effectively protect the safety of mobile phones. The use of low-quality chargers will also cause damage to the phone due to some inconsistent factors and the internal structure of the phone's charging, leading to heat and even shortening the life of the phone. Timely charging is also conducive to protecting the performance of the mobile phone, so the use of professional charger timely charging can extend the service life of the charger and the mobile phone to a certain extent.
Mobile phone battery is lithium battery, theoretically speaking, there is no memory, but the life is full of 500 times (not that only 500 times of charging), so it is best to use with charge;
Users generally regard lithium batteries as nickel-metal hydride batteries, and like to charge 8-12 hours for the first time, which is beneficial
The charging problem of smart phones has always been talked about by everyone, and many people will find that the power of the new mobile phone is used for a long time when it has just been purchased, and it basically takes half a day to lose 2% or 30% of the power. After using the mobile phone for a year or even two years, we will find that the mobile phone power is becoming less and less durable, basically, you have to charge once or twice a day, if you play games, this number will increase. So how much is the best time to charge your phone? In fact, many mobile phones will issue an alarm when the power is below 20%, which reminds us to charge. However, many people are more willful, must use the power to 10%, or even automatically shut down and recharge, in fact, this is very harmful to the mobile phone battery, often so that the battery will become more and more durable. So the so-called charge to charge to 100 percent and then unplug? On this issue, in fact, the mobile phone can be unplugged when it is charged to more than 90%, because the mobile phone has begun to use the cyclic charging mode after it is charged to 80%, so at this time, unplugging has no effect on our battery. In addition, the phone is not the best from 100 percent charge, after 100 percent we had better not let the phone continue to plug in the power supply, which will also cause damage to the battery life of the phone. In fact, in the view of Xiaobian: everyone hopes that their mobile phone can be used for a long time, and the power can be charged faster. Therefore, Xiaobian hopes that everyone can learn a reasonable way to charge a mobile phone, charge it when it is 20 percent of the power, and it is best to unplug the power cord within half an hour after charging to 100 percent, so that the service life of our mobile phone can be extended as much as possible.
As the proportion of time we use mobile phones is getting higher and higher, we all hope that mobile phones are more durable, in order to make mobile phones more durable, some consumers think that the newly bought mobile phones should be fully charged first, otherwise it will cause non-durable problems such as virtual electricity, and some even think that it is better to use up the power before charging!
Not full will not cause false electricity
The current mobile phone battery belongs to lithium battery, no memory properties, with the characteristics of charge! The newly bought mobile phone generally has about 50% of the electricity, and direct use will not cause problems such as battery deficiency, charging dissatisfaction, and non-durability, so it can be used with charging. Here we have to distinguish from the memory battery
The charging cycle of the normal life of a mobile phone battery (full charge until completely dead) is about 500 times, so it is normal for the mobile phone to use about a year and a half to change the battery. So, in the daily use of mobile phones, what problems need to pay attention to?
1, \"full discharge\" more damage to battery life
\"Full discharge\" refers to the process of using up your phone's battery until it is turned off! The phone power is used up, the operation of recharging is very damaging to the battery life, the phone power is less than 20% will remind the owner, is to play a role in protecting the battery life. Frequent \"full discharge\" machine owners, should pay attention!
< br \/ >
2, minimize charging the phone through the computer USB
Friends who have worked should know that occasionally use a computer to charge a mobile phone, but it is worth noting that USB low voltage and low current capacity, not only slow charging speed, but also easy to cause virtual electricity; With the running state of the computer, the internal current and voltage will also change, unstable current and voltage may cause instability of the mobile phone circuit, such as the screen jumping for no reason and so on!
3, do not use the charging bank when the battery is low
Carry a power bank with you when you go out, the most normal! But you know what? When the mobile phone is in a low volume, the use of a charging bank to charge not only brings loss to the charging bank, but also causes certain damage to the mobile phone battery. So friends who often use a charging bank, try to avoid low power charging yo!
< br \/ >
4. Don't overcharge overnight
After the phone is fully charged, the protection mechanism will automatically cut off the power supply, but the overnight charging will keep the phone in a full state of power, which will cause battery capacity loss and reduce battery capacity! The phenomenon of virtual electricity and non-durability is even more serious.
< br \/ >
5. Don't play while pretending
Playing while charging is easy to cause heat, especially when using non-original chargers, higher temperatures will speed up the chemical reaction inside the battery, thereby reducing battery life! If the phone is not hot, playing while charging will not damage the battery life, because the battery does not discharge when charging!
The above behaviors are affecting the battery life, resulting in the battery is not durable! But the battery is not durable may be due to its own capacity size, such as iPhone, iPhone 6 battery capacity of 1810mAh, iPhone 7 battery capacity of 1960mAh, often 3 charge a day, iPhone 8 only 1821 Ma, but Android mobile phone battery capacity is generally 4000 ma. So for Apple users, it is normal to shiver when the battery is below 70%!
Before the remaining 20% of the battery, charge the best!
