The phone battery is overdrained, can the charger be charged

It's best not to play with the phone when charging, otherwise it will be **, if you don't play, your eyes will rest, and you can also extend the service life of the phone!

Charging the phone all the time will damage the battery.

In the case of the iPhone 13 phone, the protection mechanism is activated after the battery is fully charged, so that the battery will not be damaged due to the long charging time. Most of the mobile phones now use lithium batteries. Electronic devices that use lithium batteries, including smartphones, have a charging loop that automatically de-energizes when the battery is fully charged, without damaging the battery.

On the contrary, charging the battery after "drying" it will shorten the battery life.

iPhones are generally not overcharged, and even charging a 90% charged iPhone will not damage the battery. Although the "charging cycle" of lithium batteries is limited, a partial charge will only affect the "charging cycle" proportionally. If you charge at 90% battery, only 10% of the charge cycle will be used.

Lithium battery charging precautions:

1. Keep the battery of the mobile phone between 30% and 90%, which can ensure the activity of the battery.

2. In the process of charging the mobile phone battery, it will be recommended that you do not charge it when it is often lower than 20%, so as to ensure the health of the mobile phone lithium battery.

3. In the process of charging the mobile phone, do not often rush to 100%, because often rushing to 100% will actually affect the safety of the mobile phone, because some friends may not pull out the battery at night and let the mobile phone be charged all the time, so that the mobile phone may have certain safety risks. Although the mobile phone has an overcharge protection function, it will still have a great impact on the mobile phone if it is charged in this way.

4. In the process of lithium battery charging, try to do it as much as possible, and charge it with you, so as to ensure the activity of the lithium battery of the mobile phone, and also need to know the health of the lithium battery, when it is less than 80%, you can basically consider replacing the power supply.

If you are using a vivo mobile phone, set the limb ruler to have a normal charging time of less than 3 hours. Occasional long charging will not affect the battery; If it is charged frequently for a long time, it will speed up the battery cycle counting and rolling rubber, thereby shortening the battery life, and the device should be powered off in time when it is fully charged.

Fast charging doesn't hurt the battery, but frequent fast charging does hurt the battery compared to slow charging.

1. Accelerate the polarization of battery cells

Generally, during the charging process of lithium-ion batteries, the Li+ migration rate of the internal diffusion of the electrode is smaller than that of the electrolyte, and the internal diffusion of the electrode is the control step of the Li+ diffusion rate.

Since the migration rate of Li+ inside the electrode particles is much smaller than the electrochemical reaction rate on its surface, it causes the concentration polarization of the electrode, which will further aggravate the potential difference between the positive and negative electrodes and deviate from the equilibrium potential.

When the continuous charging current is large, the ion concentration at the electrode increases, the polarization intensifies, and the battery terminal voltage cannot directly and linearly proportional to the charged energy.

At the same time, the increase of internal resistance will lead to the Joule heating effect, which will aggravate the side reactions. For example, a series of problems such as reaction decomposition and gas production of electrolyte will increase the risk factor suddenly, which will affect the safety of the battery, and the life of non-power batteries will inevitably be greatly shortened.

2. It may lead to cell crystallization

During charging, our control over the lithium ions is actually very weak. We can only guarantee that lithium ions will migrate to the surface of the anode, but we cannot guarantee that the lithium ions will be evenly distributed on the surface of the anode.

Fast charging of lithium batteries means that lithium ions quickly come out and "swim" to the anode, which requires the anode material to have a fast ability to intercalate lithium.

The anode materials used for fast charging of lithium batteries include carbon materials, lithium titanate and some other new materials. For carbon materials, because the potential of lithium intercalation is similar to that of lithium precipitation, lithium ions are generally preferentially embedded in graphite under conventional charging, but under fast charging or low temperature conditions, lithium ions may precipitate on the surface to form dendrites (also known as crystallization).

Dendrite lithium can puncture the separator (SEI), causing Li+ secondary loss and reducing battery capacity. When the lithium crystal reaches a certain amount, it will grow from the negative electrode to the separator, causing the danger of a short circuit in the battery.

In the case that the battery charge is constant.

Power marks the charging speed, and fast charging is compared with ordinary charging, which is to shorten the charging time through the following three ways to achieve fast charging.

01. The voltage remains unchanged and the current is increased.

02. The current remains unchanged and the voltage is increased.

03. The voltage and current are increased.

Of course, if mobile phones want to achieve fast charging, they not only need to improve technology. It is also necessary that the mobile phone itself supports fast charging and cooperates with the corresponding fast charging charger (including the charging head and charging cable).

If the mobile phone has a fast charging function, you can use fast charging, which will not hurt the battery.

Generally, the life of the battery is 2 to 3 years, and the frequent charging with fast charging is the big deal is to reduce the life of the battery a little bit, and it will not affect much.

If you keep using this, it will indeed hurt the battery of the phone.

The battery has a service life, the battery is not durable, you can replace it directly, you can charge it normally with normal use, don't think about it so much.

Mobile phones that do not support fast charging are better not to use fast charging chargers.

As long as it is within the allowable range of fast charging of mobile phones, fast charging will not damage the battery.

If the mobile phone has been charged, it has been charged when it is full, it will be on the battery, it is best to unplug it after it is full, do not keep charging the battery, many friends use the mobile phone, frequently charge the mobile phone, but they are afraid that this behavior will affect the mobile phone battery, this article combines the material of the mobile phone battery, and talks about the knowledge related to it.

Will frequent charging of my phone affect my battery?

The answer is yes, any electronic components have a service life, and the same is true for mobile phones and internal parts, and the battery is an energy storage component, based on its particularity, the service life even needs to be measured by the "number of uses", the general mobile phone uses lithium polymer batteries or lithium batteries, this kind of battery can be used about 300 600 times (estimated) in the "fully charged and discharged state", so frequently charging the mobile phone will accelerate the consumption of the service life of the battery.

What is a "full charge-discharge state"?

"Full charge and discharge state" refers to the two states of the mobile phone: the first is the charging state, assuming that the battery level of the user's mobile phone is displayed as 0%, then the charging starts from 0% and charges to 100%, even if it is a full charging state; The second is the state of discharge, assuming that the battery of the mobile phone shows 100%, then the user uses the mobile phone to consume the power from 100% to 0%, which is considered a complete discharge state, but in the actual use of the mobile phone, it is generally not recommended that the user consume the mobile phone battery to 0%, and it is recommended that the user charge the mobile phone when the battery level is between 5% and 15%.

What does battery life have to do with it?

There are many factors that affect the service life of the battery, such as battery material, production process, design structure, application technology, etc., but these are not controllable by mobile phone users, and related to mobile phone users are the use time, frequency of use, and use environment, the longer the use time, the mobile phone will be in a state of discharge for a long time, which will accelerate the consumption of the service life of the battery; With the increase of the frequency of use, including the number of charging and discharging, the service life will gradually decrease with the increase of the number of times; As for the use environment, it is related to the optimal working temperature of the battery, too high or too low, will cause the battery to not work properly, accelerating the consumption of service life.

Conclusion: In addition to the damage caused by its own reasons and accidents, its service life can not be measured by specific values, although the theoretical "complete charge and discharge times" can reach about 300 600 times, but in the actual use process far exceeds the value, and the battery life decline is cyclic and gradual, will not be consumed all at once, the main embodiment of the decline is that the charging is slower, the power consumption becomes faster, and the battery life of the mobile phone becomes shorter.

In addition, one thing to be clear, frequently charging the mobile phone will affect the service life of the mobile phone battery, but don't cherish the mobile phone for this reason, as long as the mobile phone is used normally, even if it is charged and discharged frequently, it doesn't matter, the mobile phone battery itself is a consumable, wearing goods, if you find that the battery life has become shorter, you can spend money to replace it, there is no need to care too much.

Does charging too fast affect the battery? Kiss! Hello, happy to answer your <>.

Yes, if you want to accelerate the charging of the charger and increase the charging current and voltage, it is equivalent to increasing the charging current, which will cause damage to the battery, and even reduce the capacity and activity of the battery, so it is concluded that the use of fast charging will definitely cause harm to the mobile phone battery. However, the average smartphone battery can reach at least 500 charging cycles, and if we develop good habits in the process of charging, there will be no serious problems in two years. Fast charging is partially harmful to mobile phones, but whether it is fast charging or slow charging, as long as it is charged, it will definitely cause permanent irreversible damage to the battery of the mobile phone, because when charging, the rapid flow of current will increase the temperature of the battery, resulting in permanent damage to the battery cells.

Fast charging will be a little more harmful than slow charging, even if fast charging has some protection mechanisms, but the impact of fast charging on the mobile phone still exists, although fast charging can greatly improve the speed of mobile phone charging, but also has a certain impact on the life of the battery, but the general mobile phone can go to the after-sales service to replace the new battery. Hope mine can help you <>

Do you have any other questions?

<> believe that most people are like me, after the phone or other electronic device is charged, they will just choose to unplug the device, and the charger will still remain on the socket. So what are the implications of this approach? The charger is always plugged in the strip.

First of all, we need to know how the charger works, in fact, it is very simple, because almost all chargers are 220V AC that we use daily.

Convert to mobile phone power. And for the current mobile phone charger, most of them belong to the power supply with conversion voltage, through the conversion voltage, so as to unidirectional integration of low-voltage mobile phone voltage, and then through a series of resistive components, the external device can be powered.

Thus we can conclude that as long as the charger is plugged into the power supply, the internal circuits and hardware will be in working condition, so it will lose power, but if it is not supplied to the device, this loss can be said to be negligible, which is what we often call no-load power consumption, and it will not lose a few kilowatt-hours of electricity in a year.

So let's go back to the second question, that is, whether the mobile phone charger should be unplugged after charging the phone. You know, as long as it is an electronic component, it has a certain number of years, and if it is used for a long time, in fact, all kinds of hardware inside it will still be in working condition. Although it is not as heavy as the load when supplying power to the equipment, it will also incur a certain amount of loss.

Therefore, it is recommended to unplug the charger after charging the device.

The second is to take into account the safety issue, the general original charger will hardly have this kind of problem, because the manufacturer will add power-off protection to its interior when designing the charger. However, if you use a charger from another small workshop, it is likely to cause a safety hazard.

Because this type of charger is likely not to have been certified for safety, once it is short-circuited, it is likely to cause safety problems such as fire.

In view of the above safety issues, I want to say more here, although the development of mobile phone battery technology is not so fast, but, in the field of fast charging, the research and development of various manufacturers is still very good, as long as you don't buy that kind of three-no product.

Basically, there will be no burning of the mobile phone charger.

Back to the initial question, whether to unplug the charger after the phone is fully charged, here it is recommended that it is best to unplug the charger after the phone is fully charged, after all, the charger has been in a preparatory state, and the internal components are also working, which is very consuming of its life. And if you don't pull it out, it will form a big safety hazard.

In short, even if it is not to save power, for your own safety, it is best to develop the habit of unplugging the charger after charging your phone. Although many people may not accept this conclusion, but not afraid of just in case, are you afraid of 10,000, do you dare to guarantee that the charger will not be a problem if it is plugged in to the socket all the time?

It doesn't consume a lot of power, because when the phone is fully charged, the power will be automatically cut off, so it won't generate too much power.
