Is it possible for a mobile phone to spontaneously combust after charging for 8 to 10 hours?

The mobile phone battery is a lithium battery, and it will not spontaneously ignite even if it is charged for eight to ten hours.

Because after the charge is fully charged, the power will be automatically cut off, and the charging will not continue.

No, mobile phones have charging management ICs, after the mobile phone is fully charged, the current will be cut off, and it will not be charged all the time, it has no impact on the battery, and it will not cause burning, of course, except for fake and shoddy products.

No, it is normal for the phone to be charged for 8 to 10 hours, and the phone will not be charged again after it is charged, and the system is intelligently controlled.

Mobile phones are all protected by circuits, they are all protected by security, and they will not **.

This is impossible, because the phone is full of it has overcharge protection, and it will automatically power off, even if you rush for 20 hours, he will not self-combust.

The main reason is that mobile phones with quality assurance or big brand mobile phones are unlikely to spontaneously combust, because the mobile phone is basically fully charged after charging for more than three hours. At this time, the phone battery will activate the self-protection function and stop charging.

Generally, this situation will not occur, and it is better to stay away from it for safer charging.

The mobile phone needs the original adaptation charger, and the general situation will not depend on a state of the mobile phone, for example, if you use it for a long time, the performance of the battery must not be very good, so you need to pay attention to it.

In contemporary society, do people control mobile phones, or do they control human beings by shouting at Wang Ji? People watch ** on their phones when they eat, listen to songs on their phones before going to bed, and even go to the toilet with their phones even if they don't bring toilet paper. Many office workers and student parties are unable to work without mobile phones, and they are not satisfied with their mobile phones and do not go out of their homes.

In order for the phone to be "resurrected" the next day, it is necessary to charge the phone before going to bed at night. As soon as I closed my eyes, I opened my eyes, and the whole night passed, and this mobile phone also slept all night. Some people are going to ask:

Now that technology is becoming more and more developed, the security performance of our mobile phones is getting stronger and stronger, and when the mobile phone is fully charged, the mobile phone will automatically stop charging. Every mobile phone manufacturer has a different way of managing the battery. Learn that Apple's battery management is like this:

When the phone is fully charged, the iPhone will stop charging and then release 5% of the charge before charging. Therefore, the harm of charging the mobile phone overnight is very weak, but the premise is to use the original charger, if you use a non-original charger, I advise you to get an original one.

There are also many Tongqing Yuxue who want to ask, will the mobile phone affect the life of the mobile phone while charging and playing? Or will charging while playing make the phone **? In the process of charging while playing, the mobile phone will be heated, the hot mobile phone must attract our attention, now Zheng Huzai in the battery we use is a lithium battery, its temperature increases by 10 degrees Celsius, the chemical reaction will be increased by two times, but will accelerate the use of electricity, if the temperature exceeds 45 degrees Celsius, the chemical balance in the battery will be broken, producing greater and stronger heat, the damage to the battery is great, and the hardware of the mobile phone will also be harmful, but in general, it will not produce **.

The premise of the general situation mentioned here is that the charger you use must be original. There may be students who are going to give full play to the questioning ability of "naughty 30 million questions" again, and they want to ask:

How to explain the ** incident between Apple and Samsung? This kind of news, don't be scared by the gimmick of "**", go to the truth of the matter! The reason for the occurrence of ** is precisely because the original charger is not used, which leads to the mobile phone**.

In addition, in order to make our phones "last longer", the optimal charging amount is 30% to 40%, and what we think of recharging after use is actually incorrect.

The size of the general battery capacity is expressed in milliamps, the larger the value, the larger the capacity, for example, 1200mAh means that the capacity of the battery is 1200 milliamps, the length of charging time, and the charger is related, the charger is generally marked with the charging current, but also expressed in milliamps, the length of charging time is calculated as: the battery capacity divided by the charging current of the charger, and then multiplied by the coefficient, you can.

The unit of time is hours. For example, if the capacity of the battery is 1200 mAh, and the charging current of the charging fiber or device is 600 mAh, (1200 mAh 600 mAh) * hours, the charging time of this battery is = hours.

Charging time is not always better!

Some mobile phone users have such an idea: when charging the mobile phone, because they are worried that the battery is not sufficient, the charging time is too long, thinking that this is more safe, but is it better to charge the longer the better

Reasons why lithium mobile phones should not be "charged for a long time":

1. In order to make full use of the capacity of the battery, the overcharge and overdischarge circuit of any manufacturer will be set near the limit value, and the margin is not large. Because of this, often using the phone at the limit state of battery charging and discharging, once there is a problem with the protection of the battery and charger, it is very detrimental to the life of the battery. Sometimes it can be fatal.

2. Since there is protection for overcharging, a long charging time is meaningless, unless you want to conduct a life test on the charger. Special attention should be paid to the fact that the lithium battery charger will automatically stop charging after being fully charged, and there is no so-called "trickle" charging that lasts for more than 10 hours in the nickel battery charger. That is to say, if the lithium battery is fully charged, it is also white charged when placed on the charger.

None of us can guarantee that the characteristics of the charging protection circuit will never change, and once the charging time is too long, the battery will be on the verge of danger for a long time.

3. The number of charges of lithium batteries is related to the depth of discharge, for example, an experimental table about the charge and discharge cycle of lithium ionized batteries, and the data on cycle life are listed as follows:

Cycle life (10% DOD): > 1000 times.

Cycle life (100% DOD): > 200 times.

DOD is the abbreviation for Depth of Discharge. As can be seen from the table, the number of charges is related to the depth of discharge. To put it simply, if you're charging halfway, you don't lose one more charge life, that's just a few times, and the x is often small.

4. The memory effect of lithium batteries is almost non-existent, and the need for activation is extremely weak, so natural use is enough to activate.

Special reminder: It is best not to carry out "long charging" for lithium batteries, even if you are in the period of hunger of the first three charges. It's okay to be full! At the same time, it is also opposed to using lithium mobile phones to turn off their own phones. Because none of these are good for the battery.

Definitely not. Anyway, the mobile phone is also a smart thing, and it is a simple matter like charging, and it is still accurate to judge when it is full and blind.

Once fully charged, the phone will cut off the charging loop and crack the sky, and will not continue to rush.

If there is no such charging management and the protection circuit in the lithium battery, do not 24 hours, as long as the mobile phone lithium battery is overcharged in the actual sense of 2 4 hours, 100%**.

It's good that there isn't.

Mobile phones have now become a necessity for everyone's life, that is, children have to play with their parents' mobile phones. In our current life, we will lose a lot of convenience without our mobile phones.

But nowadays, many mobile phone batteries are becoming less and less durable, and they run out of power for half a day after each full charge. But even so, many people will habitually charge their mobile phones before going to bed, and then charge them all night.

Is this kind of charging harmful to the battery? The owner of the mobile phone store said that in the previous time, there was indeed a hidden danger that if the mobile phone was charged for a long time, the battery would be the first to be charged. But the previous mobile phones are not as good as the current ones, and the technology does not know how much it has improved.

Nowadays, many mobile phones have the function of automatically powering off, and they will continue to lose power after the charging is completed, so we don't need to worry too much.

But now there are still mobile phones, and they are suddenly ** when they are used. At present, most of the lithium-ion batteries used in mobile phone batteries will automatically turn off the power when they are fully charged, and then continue to charge after the power is low, and the loss of the intermediate battery is negligible. And usually some people wait until the mobile phone runs out of power before charging, in fact, this way will hurt the battery more.

No, today's mobile phones are developing by leaps and bounds, and security is almost no longer a concern.

No, because the battery is often charged overnight, so it doesn't matter.

But now there are still mobile phones, and they are suddenly ** when they are used. Nowadays, most mobile phone batteries use lithium-ion batteries, which will automatically turn off when fully charged.

Is there any harm to the battery if the mobile phone is charged "overnight"? After reading the increase knowledge.

No, most of the lithium-ion batteries used in mobile phone batteries will automatically turn off when fully charged.

The power goes off when the charging is complete, so we don't need to worry too much.
