Details are as follows:

1. Don't charge the mobile phone after it is exhausted: in fact, if the lithium battery is in a low voltage state for a long time, it will lead to the phenomenon that it cannot be charged. So when the battery of the mobile phone drops below 20%, it's time to charge it.

2. Don't continue charging for a long time after the mobile phone is fully charged: theoretically, the mobile phone will automatically stop charging after it is fully charged, but the battery will overheat or even burn out during the charging process. We should try to avoid charging the mobile phone unattended for a long time.

3. Don't play with your mobile phone while charging: We should try to avoid overheating when using smart phones. If you play mobile games again at this time, the heat emitted by the battery and the processor will be superimposed. In the long run, it will cause irreversible damage to the battery and even the components inside the mobile phone, so there is no need to try not to use the mobile phone while charging.

4. Don't use a non-original charger or charging cable: Whether it's an Apple phone or an Android phone, the original charger is a standard USB interface with a built-in protection chip.

5. Don't charge your mobile phone with a charging treasure for a long time: Although many charging treasures can provide high current of 1A or even more than 2. 1A, charging treasures are not a power source after all, and cannot guarantee the continuous and stable output of voltage/current.

Precautions for using mobile phone battery:

1, don't use the broken battery: the broken battery is easy to explode, even if it doesn't explode, it will damage the mobile phone, causing short circuit of the internal devices of the mobile phone, so don't use the broken battery.

2. Don't modify the mobile phone at will: Improper modification of the mobile phone can easily lead to the explosion of the mobile phone. Mobile phone is a kind of sophisticated communication equipment. Manufacturers will conduct strict research on its safety when designing, and the battery performance is also the best. But when it is modified, all this will change, which will easily lead to the explosion of the mobile phone.

3. Don't put the battery in a high temperature environment: High temperature will lead to the increase of battery heat and explosion, so when charging the battery or placing the mobile phone, you must choose a place far away from high temperature and avoid direct sunlight in summer.

4. Don't talk on your mobile phone for a long time: Talking for a long time will not only cause the battery of the mobile phone to heat up, but also cause the internal circuit and receiver of the mobile phone to heat up. If a fake battery happens to be used at this time, it is easy to cause an explosion.

2. Common sense: How to maintain your mobile phone battery

Maintenance of mobile phone battery

The maintenance of mobile phone battery should start from the first charge. The first charge has a great influence on the service life of the battery in the future. Generally, the first charging time is required to be 16 hours (if the battery is fully charged, it should be used up first), but remember not to exceed 24 hours, otherwise the battery may be fully charged. After charging, it is required to recharge after each use for about 5-6 hours each time. For a new battery, it needs to be charged and discharged many times to achieve the best use effect.

It should be noted: Do not charge the battery when it is half used or the used battery suddenly stops using for several months. The standard service life of a battery is one year. After one year of use, the battery can be discharged every two months, which has a good effect on prolonging the service life of the battery, but it is not necessary to recharge the new battery after each discharge. Finally, please note that the leaking battery should not be used again, otherwise the loss will outweigh the gain.

When charging the battery, use the original charger, and try not to use a charger that can charge multiple machines. Generally, mobile phones are equipped with travel chargers. If possible, you should use a seat charger. From the point of view that mobile phone manufacturers keep the function of charging directly through mobile phones, there should be certain technical guarantee. However, from the analysis of damaged components, the charging current is generally too large, which exceeds the load of the charging circuit in the mobile phone. The main reasons for this kind of failure are as follows: First, the power grid voltage in many cities in China is unstable, especially at night; Second, the battery quality is not good, or the battery power is used too hard. For mobile phone users, it is best to use fast charging as a temporary or emergency charging method at present, with seat charging as the main charging method. Because even if the latter method fails, it will not cause damage to the mobile phone itself.

If conductors such as jewelry, keys or beads come into contact with the exposed electrodes of the battery, these substances may make the current form a loop and become very hot, causing harm to people. In order to prevent accidental leakage, you should properly place the charged batteries and pay special attention to the batteries in your pockets and bags. After the battery of the mobile phone is removed, it should be put in a protective case. When the battery is not used for a long time, it should be placed in a protective sleeve and stored in a dry and dark place. Never put the cell phone battery at a high temperature (above 60℃), such as under a window with high temperature and direct sunlight. In addition, using lithium battery in low temperature environment may not guarantee the ideal standby and talk time of mobile phone.

3. How to maintain the mobile phone battery

Common sense of mobile phone battery maintenance

1. When you don't use your phone for a long time, please take out the battery.

2. You can always wipe the contact between the mobile phone and the battery electrode with a small amount of anhydrous alcohol to avoid poor contact between the battery and the mobile phone.

3. To remove the stains on the appearance of the mobile phone, you can scrub it with cotton dipped in a small amount of anhydrous alcohol.

4. Try to use the seat charger to charge, which will help to extend the battery life.

5. Please use the charger of the original factory or reputable brand, and use the special charger for lithium battery, and use it according to the instructions, otherwise the battery will be damaged or even dangerous.

6. The time should not exceed 24 hours.

7. When charging, try to charge slowly and reduce the fast charging method.

8. If the battery is newly bought or not used for a long time, please rinse the battery before use.

9. After three or five complete charge and discharge cycles, the chemicals in the battery will be fully activated to achieve the best use effect.

10. Before charging, the Ni-MH battery and lithium battery do not need special discharge. Improper discharge will damage the battery.

1 1, all mobile phone batteries have self-discharge. When not in use, the Ni-MH battery will discharge with the remaining 1% every day. Lithium batteries will discharge at 0.2%~0.3# every day.

12. Never place the phone and battery under high temperature (above 60℃) or direct sunlight windows.

13, the mobile phone should not be flooded, and it should be waterproof when used or carried in rainy days. Don't turn it on if you accidentally get water. Take out the battery immediately and hand it over to a professional.

14, don't use non-original batteries and chargers, which will easily damage the mobile phone or battery.

15, the charged battery should be properly placed, and special attention should be paid to metal objects such as pockets, wallets, keys in bags and Thai baht treasures. , so as to avoid contact with the exposed electrode of the battery, so as to avoid loss of articles or battery damage.

16, turn off the power of the mobile phone when taking the battery, otherwise it will damage the memory of the mobile phone.

17. Please turn off the power of the mobile phone before inserting or removing the SIM card, otherwise the memory of the SIM card will be damaged.

18, please do not change or set the password unless necessary, otherwise the machine may be locked or stuck due to misoperation. If the password of the SIM card is entered incorrectly for three consecutive times, the SIM card will be locked; if the password of the SIM card is entered incorrectly for ten consecutive times, the SIM card will be scrapped.

4. Mobile phone battery maintenance method

Tips for cell phone battery maintenance 1: Pay attention to the charging of new mobile phones.

The batteries of the newly bought mobile phones are all lithium batteries, and the manufacturers have activated them, so each new mobile phone battery will have residual power. Therefore, the first three to five charges of the newly purchased mobile phone are the adjustment period, and should be kept for more than 14 hours each time to ensure the full activation of lithium ions and achieve the best use effect.

Mobile phone battery maintenance coup 2: lithium battery does not need to discharge, charging as slowly as possible.

Many netizens think that mobile phone batteries should be discharged first and then recharged, which is wrong. Lithium batteries are unnecessary, can't discharge, and now they have no discharge function.

In addition, it is recommended to charge slowly as much as possible to reduce the loss of mobile phone batteries. Note: No matter slow charging or fast charging, it should not exceed 24 hours, otherwise the battery will be burnt out due to the huge electron flow generated by long-term power supply.

Mobile phone battery maintenance coup 3: Don't cut off the power immediately after it is full.

When the mobile phone battery is charging, if the mobile phone or charger shows full, please don't turn off the power immediately, because the mobile phone battery is actually only 90% charged at this time. You should charge the battery for a period of time before using it, otherwise it will shorten the use time.

Mobile phone battery maintenance coup 4: Try not to turn on the phone when charging.

If the mobile phone is still on when charging, the battery of the mobile phone will discharge outward due to the use of the mobile phone, and power will be supplied inward due to the charging of the battery, which will easily cause the circuit board of the mobile phone to heat up due to voltage disorder. If there is an incoming call, it will generate instantaneous backflow current and damage the internal parts of the mobile phone.

Mobile phone battery maintenance coup 5: Recharge the battery when it is used up.

The charging times of the mobile phone battery determine the life of the battery. Generally, a lithium battery can be continuously charged and discharged for about 500 times, and then the battery performance will be greatly weakened. Therefore, it is recommended that you try to recharge your mobile phone battery after it is exhausted or automatically turned off.

Mobile phone battery maintenance coup six: pay attention to protect the mobile phone battery

If you want to maintain your mobile phone battery in place, you should also pay attention to protecting it. Therefore, don't put the battery in a hot or cold place, like dog days, and don't expose the mobile phone to the sun; Or take it to an air-conditioned room and put it in a place where the cold wind blows directly. When charging, the current product refluxes, and it is normal for the battery to get a little hot.

Mobile phone battery maintenance coup seven: need to activate after a long time of non-use.

If the cell phone battery is not used for a long time, you should first go to a special cell phone repair point to activate the battery, or you can use a DC constant voltage device to adjust the voltage to 5~6V and the current to 500~600mA to reverse the battery. Note: hair-trigger, repeat up to three times. After this treatment, the original charger is used for "adjustment period" charging.

Mobile phone battery maintenance coup 8: charging time is not as long as possible.

When charging a mobile phone, it should be noted that the longer the charging time, the better. If there is no protection circuit or a non-genuine battery, it should be powered off immediately after it is fully charged, otherwise the performance will be affected by heat or overheating.

Attachment: calculation method of theoretical charging time of battery;

The battery capacity can be divided by the output current of the charger. For example, if the output current of a battery with a capacity of 800MAH is 500MA, the charging time is equal to 800MAH/500MA= 1.6 hours. Of course, this is only a theoretical calculation of fully charged time. When the charger shows that the charging is complete, it is best to charge the battery for about half an hour. Special charger must be selected for lithium-ion batteries, otherwise it may not reach saturation state and affect performance.

Mobile phone battery maintenance coup 9: Small details can also extend battery life.

After long-term use, the contacts of the mobile phone battery will be oxidized, resulting in the automatic shutdown of the mobile phone or automatic disconnection during the call. At this time, you can wrap a paper towel with a small cotton swab or toothpick and wipe it with a little alcohol. Never scratch with hard objects, which will aggravate poor contact. No alcohol can be replaced by highly alcoholic liquor. Immediately after wiping, dry it with a paper towel to avoid the short circuit between the two poles of the battery caused by alcohol overflow. The chemicals in the new battery will be fully "activated" after 3-5 complete charge and discharge cycles to achieve the best use effect.

Handset battery maintenance coup 10: use the original battery of the handset manufacturer.

Remind netizens, please try to use the original mobile phone batteries and chargers provided by mobile phone manufacturers, or use regular products, and don't buy mobile phone batteries and chargers in street stalls or unreliable places.

Attachment: Appearance characteristics of genuine mobile phone battery, which is convenient for you to identify when you buy it in the future:

Authentic mobile phone batteries generally have the following appearance characteristics: the battery label adopts secondary printing technology. In a certain light, the color of the bar code part is obviously darker than other parts when viewed from the inclined plane, and it feels slightly convex when touched by hand. Many original batteries have this feature. The white part of the surface of the genuine battery label is lightly scratched with a metal object, and there are traces similar to pencils. The battery case is made of special material, which is very strong and not easy to be damaged. In general, it is not easy to open the battery case. The appearance of the battery is neat, there is no redundant burr, the outer surface has a certain roughness, and it feels comfortable.

5. Who has common knowledge about the use and maintenance of mobile phone batteries?

A common misunderstanding about battery charging.

Whether buying a mobile phone or buying a battery alone, merchants usually tell users that the first three charges must be fully charged 12 hours. In fact, this is the experience left over from the era of Ni-Cd/Ni-MH mobile phone batteries.

Because of the obvious memory effect of Ni-Cd/Ni-MH, it needs deep charging and discharging to "activate" the battery and give full play to its best state, but this experience is not suitable for all kinds of mobile phones that generally use lithium-ion batteries in the market at present. Lithium batteries have no memory effect, and new batteries can be fully "activated" after normal charging and discharging for three to five times, while deep charging and discharging is harmful to lithium batteries, and many batteries have been "activated" before leaving the factory.

Therefore, it is troublesome and unscientific to charge the first three times with 12 hour, and in some cases it will have a certain impact on the service life of the battery. Users should pay attention to changing this misunderstanding. What good batteries are worth buying? The mold of the battery is well-made, the size should be the same as that of the original battery, and it looks like the back of the mobile phone, with moderate tightness and no blockage. Models with battery covers will not feel too tight or too loose.

@ There are no scratches and stains on the surface of the battery case. The positive and negative metal contact pieces of the battery should be clean and bright, and there should be no corrosion or coating shedding.

@ Shake the phone gently after turning it on, and the phone won't turn off because of poor contact. It behaves normally during use and charging and discharging, and the surface will not be overheated and deformed.

@ Battery clearly shows the charge and voltage of the battery. The capacity should be close to or higher than the original battery.

If the capacity is lower than the original battery, there should be little difference with it. At the same time, the standby time in use can replenish the capacity (indicating that the battery capacity is not empty). Knowledge of battery use and maintenance Although many batteries and chargers have overcharge protection, it is necessary to avoid charging for a long time during use.

Especially the overcharge of lithium batteries will have a great impact on the service life. @ Lithium battery has no memory effect, so it can be charged at any time during use, without waiting until it is completely exhausted every time.

Of course, if conditions permit, you can still use it as much as possible before recharging. @ Try to use direct current (use the original charger of the mobile phone to charge through the mobile phone). Although the universal charger is easy to use, it should be avoided as much as possible.

Because the quality of universal chargers on the market at present is uneven, and the universal chargers themselves have a wide range of applications, they can not adapt to a certain type and capacity of batteries, thus affecting the service life of batteries. Attention should be paid to moisture protection during use and charging and discharging. Humidity can easily lead to battery short circuit accidents.

@ If the battery is not used for a long time, it should be charged and maintained once every six months.

6. How to maintain the mobile phone battery?

1, the first charge is not as long as possible, nor does it say how many hours it must be charged. It is about charging 1 or 2 hours after the battery light shows full charge.

2. The larger the capacity of the mobile phone battery, the better, because the battery with small capacity has more charging times-the life of the rechargeable battery is calculated according to the charging times. On the contrary, the battery with large capacity will charge less times, and the battery with large capacity just saves the trouble of frequent charging. However, whether it is a large capacity or a small capacity, you need to buy a battery produced by a regular manufacturer that matches the mobile phone, otherwise it may have a great impact on the mobile phone. Three batteries are more likely to explode, and large-capacity batteries are more dangerous.

Some people think that it is better to charge the battery directly with the seat charger than with the mobile phone, because they think that charging the battery directly with the mobile phone may damage the mobile phone due to heat. Actually, it's just the opposite. Because the voltage required by a low-power battery is different in the early and late stages of charging, it is impossible for a low-cost charger to adjust the voltage so finely; The mobile phone itself is a high-priced circuit board, which can adjust the voltage more intelligently when charging, which is conducive to extending the battery life.

Nowadays, almost all mobile phones use lithium batteries, and there is no "power memory" phenomenon, so there is no need to worry about whether the battery will be charged or dead, and it will not damage the battery.

5. The battery will be cut off as soon as it is fully charged, because overcharge is more harmful to the battery than undercharge. So try not to charge the battery before going to bed, thinking that the battery is full after waking up, which is actually very harmful to the battery. Because the battery life is measured by the number of times it can be charged, although the fourth article says that it can be charged at any time, it is of great benefit to extend the battery life by using the battery in a small space (point) and charging it at one time, and not overcharging or undercharging it.

6. Battery storage: If the battery is not used for a long time, it must be fully charged and sealed to avoid moisture, every month (or three months? Sorry, I really can't remember) take it out and recharge it, because the self-discharge phenomenon of the battery is very weak, but it can't be completely ignored. If self-discharge is too much, the battery will be in a low state for a long time, and may even enter a "sleep" state and then "wake up".

7. How to maintain the mobile phone battery?

Second, the battery quality is not good, or the battery power is used too hard. The first charge has a great influence on the service life of the battery in the future. Generally, the charging current is too large, which exceeds the load of the charging circuit in the mobile phone. The charged battery should be properly placed to cause harm to people. Finally, please note that the leaking battery should not be used again, which will not cause damage to the mobile phone itself.

If conductors such as jewelry, keys or beads are in contact with the exposed electrode of the battery, it is generally required that the first charging time is 16 hours (if the battery has been charged, it should be used up first), but remember that it should not exceed 24 hours, otherwise the battery may be charged, and special attention should be paid to the batteries in pockets and bags. After taking out the battery from the mobile phone, put the battery in a protective case and store it in a dry and dark place. Don't put the cell phone battery at high temperature (above 60℃). If placed in a window with high temperature and direct sunlight, use the original charger. Try not to use a charger that can charge multiple machines at once. Generally, mobile phones are equipped with travel chargers. After charging, it is required to recharge after each use for about 5-6 hours each time. For a new battery, it needs to be charged and discharged many times to achieve the best use effect.

It should be noted that. In addition: don't charge the battery when it is half used or the used battery suddenly stops using for several months. The standard service life of a battery is one year. If possible, charging with a seat is the main charging method. After one year of use, you can discharge electricity every two months. At present, it is best to use fast as a temporary or emergency charging method. Because even if the latter method fails, it has a good effect on prolonging the service life of the battery. The battery should be kept in a protective sleeve, but it is not necessary to charge the new battery every time after discharge, otherwise it will not be worth the candle.

When charging the battery, try to use the seat charger. From the point of view that mobile phone manufacturers keep the function of charging directly through mobile phones, there should be certain technical guarantee. However, the maintenance of mobile phone battery is analyzed from this fault component.

The maintenance of mobile phone battery should start from the first charging, and there have been such failures. First, the grid voltage in many cities in China is unstable, especially at night. When the battery is not used for a long time, use the lithium battery in a low temperature environment. For mobile phone users. In order to prevent accidental leakage, these substances may make the current loop very hot.
