Is there any harm in charging the phone overnight?

Yes! There is a degree of saturation when charging a mobile phone, and if you continue to charge it when you reach saturation, it will reduce the tolerance of the battery.

There is no harm, because the mobile phone is now very developed, and he will carry out charging protection when the mobile phone battery is full to prevent the battery from being in a charging state, but considering the electricity bill, we still try not to let the mobile phone be charged overnight.

Due to the power consumption is not much, it will use low current charging, so that the mobile phone battery will not be reduced due to repeated charging, and the mobile phone will not wait until the power is low to recharge, because at that time the PMU will protect the mobile phone battery, in this state the charging speed is not only very slow but also will be heated.

In fact, the mobile phone is charged overnight, and this charging method is not harmful to the use of the battery at all! It is best to charge between 20% and 60% of the battery level, or we can choose to charge in the fastest range of battery charging to improve the service life of the lithium battery.

The truth of the matter is that this way of using is basically not harmful to the battery of the mobile phone, because the battery of the smartphone has been designed with this problem in mind, so it comes with the corresponding PMU (battery management scheme). Through the PMU (battery management scheme), the charging will be automatically cut off when charging, even if it is connected to the charging cable, it will not continue to charge, even if the standby consumes a certain amount of power, PUM will only trickle charge the mobile phone, charge at a very low current, and repeat the cycle, such a charging method is not harmful to the use of the battery at all. And to everyone's surprise, the battery charging method that is the most harmful to the mobile phone battery is:

Recharging after the battery is depleted, according to the charging curve, it can be seen that low-power charging is the slowest, and this is also caused by the PMU's protection scheme for the battery.

There is no harm, because now smartphones have PMU charging management chips, the battery will stop charging after it is fully charged, and the standby phone plugged into the charging cable at night will not consume its own battery power, and there is no standby power consumption and then repeated charging problem.

When the device prompts "low battery", it should be charged; Charging is not until the device is automatically turned off, and the battery has been over-discharged. This can affect battery life. Do not overcharge.

When the charger gives a full charge, it should be unplugged. The current charger generally has a full self-stop design, and it doesn't hurt to remove the battery from the charger for a short time, but if the charger is connected for a long time, the grid voltage rises in the middle of the night, and the charger that has stopped charging will continue to charge after the voltage rises, causing the battery to overcharge. This can affect battery life.

There's really no harm. Because the chargers of today's mobile phones are all intelligently powered off. In other words, after a full charge, it will not continue to charge, and it is unlikely that there will be anything like charging** at all, unless the quality of your charger is not up to par.

It will not hurt to charge the mobile phone overnight under normal circumstances, we only need to pay attention to maintenance: avoid charging when the power is too low, use the original regular charger, try not to charge while playing games, and develop such a habit at least not to let our mobile phone battery life loss too fast.

How convenient and how to charge, just charge as you go. Because most of the current smartphones use lithium batteries, lithium batteries have no memory effect. Therefore, if the charge is not sufficient or not used, it will not affect the life and capacity.

Plus, the advantage of charging at night is that the battery is full when you go out in the morning. Everyone is most worried about whether there is any harm in charging overnight, and whether it will be charged? Or is it leakage or damage to the phone?

Actually, it won't.

Almost all smartphones on the market use lithium batteries, so when the mobile phone battery is fully charged, the power will be automatically cut off, so don't worry.

Now the mobile phone has long been lithium battery, the life of the lithium battery is mainly based on the charging cycle, if only 10% of the electricity is off and then full, this is only one-tenth of the charging cycle, so the best way to maintain is to charge with use, do not deep discharge and charging, and at night we have been charging the mobile phone after sleeping will naturally keep the mobile phone fully charged, which is not harmful to the mobile phone lithium battery itself.

In our use scenarios in reality, we generally play with the mobile phone before going to bed, and then plug it in for a night, so that charging for a long time will theoretically have irreversible damage to the lithium battery of the mobile phone, but the actual situation is just the opposite. If the mobile phone lithium battery is continuously charged without any protective measures, the chemical components inside the battery will be passivated, resulting in insufficient discharge, which will permanently affect the battery life. But the reality is that almost all smartphones today are equipped with charging protection ICs (chips) in both the mobile phone and the adapter, which will monitor the battery level in real time.

When the chip detects that the battery is saturated, it will greatly reduce the charging power or even automatically cut off the power supply and enter trickle charging mode. In this way, there is no such thing as continuous and uninterrupted charging. Therefore, with the check of charging protection IC, the damage to the battery caused by charging the mobile phone overnight is much lower than the loss of the battery in normal use, and there is no need to worry about harming the battery.

There is no impact. Charging your phone overnight will not affect the life of your battery.

Each lithium battery has a fixed charge cycle, which refers to the number of full charges a smartphone battery can take before it degrades significantly.

Therefore, the life of a smartphone can only be determined by the number of times you charge it, not the charging time. The average smartphone battery has about 400 charging cycles, and such charging cycles can guarantee the user's normal use for at least a year and a half.

Charging the mobile phone overnight will affect the life of the mobile phone battery, we can clearly see in the instruction manual of the mobile phone that the charging time of the mobile phone can not be more than 5 or 6 hours, if the long-term charging will damage the battery, and even reduce the service life of the battery.

On the other hand, if you charge it overnight, the mobile phone is easy to heat up, which may cause other safety hazards such as disasters, so you should not charge it overnight.

When the mobile phone is fully charged, remember to unplug the charging handle of the mobile phone in time, which can eliminate some potential safety hazards, so as not to cause fire and other accidents.

1. Charging overnight will make your mobile phone battery reach a supersaturated state, causing the chemical reaction material inside the battery to passivate, reducing the degree of chemical reaction when the power is output, and then damaging the battery. 2. However, for some brands of mobile phones, there are certain protection measures in the battery chip, after the mobile phone is charged to saturation, the power will be automatically cut off after a period of time, preventing further charging, which is also to prevent users from charging mobile phones all night to make technological innovations. 3. When the battery is not fully used up, it will be charged, and the battery will be charged when the battery is about 20, which will prolong the life of the battery.

Of course, if you use up all the power every time and then charge the phone after it automatically shuts down, it will have the greatest impact on the battery life, which will seriously shorten its life. 4. There is a charge and discharge control circuit in the circuit of the mobile phone, and the genuine battery also has a charge and discharge control circuit As long as the mobile phone is normal, use the genuine battery, when the charging starts, it is a high-current charge, and when it is charged to 80, the circuit automatically turns into a small current charge, that is, when the charge reaches 100, the circuit automatically cuts off the charge. 5. Note:

When the phone shows that the charging is full or the charging is over, the battery is not fully charged, only 80, at this time it enters trickle charging, about two hours or so, it can be fully charged, reaching 100.

If you are using a vivo mobile phone, occasional long-term charging will not affect the battery; If it is often charged for a long time, it will add a quick battery cycle count, thereby shortening the battery use time, and the device should be powered off in time when it is fully charged.

1. Don't wait for the power to run out before charging, over-discharge will have a certain impact on the battery, in serious cases, it may cause the device to fail to turn on normally, try to charge in time when the power is too low;

2. It is recommended to use the original charger and data cable for charging, and the non-original charger may have various problems, which may damage the battery and reduce the service life of the battery;

3. When charging, try not to play while charging, at this time, it is easy to increase heating, easy to lose the battery, and shorten the service life of the battery;

4. After the charging is completed, please disconnect the power supply in time to avoid charging for a long time;

5. Avoid using the equipment in a high-temperature environment.

Many people are accustomed to charging their phones before going to bed at night and unplugging them the next day. Therefore, there are many people who are worried that charging their mobile phones overnight will affect the life of their mobile phones. Here I tell you that it will not affect the life of the phone.

Because there will be a power management chip inside the smartphone, those who can understand it will know that it is the power management LC. In daily applications, the power management chip is responsible for monitoring not only the power consumption of the battery, but also the entire process of battery charging. For some mobile phones that support the fast charging function, the power management chip also shoulders the responsibility of shaking hands with the charger and dynamically coordinating the charging current and charging voltage.

It is not difficult to see that the power management chip is an all-round housekeeper, and in the process of charging, the power management chip will monitor the charging status in real time. Once the battery is fully charged, the power management chip will automatically cut off the power supply, and the charger will directly power the phone. Therefore, under the protection of the power management chip, the mobile phone can be charged overnight, which will not damage the battery and will not damage the life of the mobile phone.

1. There is no effect on charging the mobile phone overnight, because the current mobile phone batteries are lithium-ion batteries, it has no memory function, it can be charged at any time, and it can be charged without power.

2. Charging is a Chinese word that refers to the process of replenishing power to batteries and other equipment. The principle is to let the direct current pass in the opposite direction of the discharge, so that the active substances in the battery can resume their effects. It has extended meanings such as study, work, etc.

The working process of the battery receiving electrical energy from the external circuit and converting it into the chemical energy of the battery. After the energy of the battery is consumed by discharge, it can be restored by charging and can be re-discharged, constituting a charge-discharge cycle. Generally, it is charged with DC current (also with asymmetric AC current or pulse current).

In different cases, different charging methods are used, such as constant current charging, constant voltage charging, floating charging, trickle charging, emergency charging or a combination of these methods.

3. High-voltage charging: high-voltage and low-current mode, increasing voltage, it is necessary to design multiple step-down circuits in the charging circuit. When charging, the charger will heat up, and the phone will also heat up, and the safety of the battery will be affected.

Low-voltage charging: low-voltage high-current mode, increasing current, introducing MCU monolithic microcomputers in both charger circuits and battery circuits to replace step-down circuits. Under the premise of low voltage and high current, the output of the current with segmented cross-flow is realized through the open voltage loop.

VOOC flash charging uses the solution of low voltage and high current to ensure safety and solve the problem of mobile phone charging and heating.

If you are using a vivo mobile phone, the normal charging time of the device is 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, thereby shortening the battery life, and the device should be powered off in time when it is fully charged.

1. Don't wait for the power to run out before charging, over-discharge will have a certain impact on the battery, in serious cases, it may cause the device to fail to turn on normally, try to charge in time when the power is too low;
