No harm
Charging the phone overnight will not damage the phone, and the smartphone will automatically power off when it is fully charged, so it will not continue to charge the battery. The phone can not be charged, may not use the original power adapter, it is recommended to use the original charger.
1. You can view the remaining battery in the status bar of the phone. Take the Xiaomi phone as an example, open the system setting page of the Xiaomi 9Pro, click \"Notification and status bar\
2, the mobile phone generally has a low power mode, you can open in the battery setting page, after opening this function, the performance of the mobile phone will be affected.
3, want to extend the battery life of the phone, you can turn off the wifi, Bluetooth, positioning function, reduce the brightness of the phone screen can also extend the battery life.
\"Lithium battery\" is a class of lithium metal or lithium alloy as a negative electrode material, the use of non-aqueous electrolyte solution of the battery. Lithium ion batteries are divided into liquid lithium ion batteries and polymer lithium ion batteries. The electrolyte of lithium-ion batteries is flowing, so it is more unstable than lithium polymer batteries, and it may cause the battery to explode when it encounters external force, or when it uses a charger that does not meet the standard
There will be damage.
1, during the charging process of the mobile phone, the battery will generate heat, and if it is charged for a long time, the battery temperature will be too high, thus accelerating the aging of the battery.
2, for the battery of modern mobile phones, it is not recommended to continue charging after full charge, overcharging will lead to a decrease in battery capacity, and may cause battery leakage, fire and other dangers.
3, so it is recommended not to let the phone charge overnight, you can choose the charger with stop charging function or use a special charger to protect the battery and extend the battery life.
Often charging overnight will not cause damage to the mobile phone battery, because the life of the mobile phone battery is related to the number of charging cycles, and the charging time and number of times are only one factor affecting the battery life.

Modern smartphone batteries have a certain intelligent charging control circuit that automatically stops charging after the battery is full to extend battery life. Therefore, even if the phone is charged overnight, the battery will not be damaged by overcharging.

However, it is recommended not to charge before bed, as charging before bed may affect the quality of sleep. In addition, do not expose the phone charging to high or low temperatures, as this may cause damage to the battery.
Charging the phone overnight will not cause problems to the battery, because most modern smartphones use lithium-ion batteries, which have a built-in protection circuit to avoid overcharging and overdischarging, which means that when the battery reaches 100%, the charger will be cut off and will not continue to charge the battery, so the battery will not be affected by overcharging.
However, leaving the phone fully charged for a long time will keep the lithium-ion battery in a high voltage state, which will slightly reduce the battery life. Therefore, in order to maximize battery life, it is recommended not to let the phone fully charged, but to start charging when the battery level is below 20%, and unplug the charger when the battery level reaches about 80%. This can help extend the life of lithium-ion batteries.
No harm
Now the mobile phone has its own charging intelligent system, can automatically identify whether you need to continue to charge, if your mobile phone is full of power, it will automatically stop charging, if your mobile phone power is reduced to a certain range, he will continue to charge, so there is no damage to the mobile phone charge overnight.
Charging for a long time will cause some damage to the battery, but modern smartphones are equipped with advanced lithium-ion batteries and charging protection functions, and generally will not cause too much impact on the battery. When the phone battery is already full, the charger will automatically stop charging, and will not cause overcharging.
However, if you often use unqualified chargers or improper use, such as charging with a high-voltage power supply, charging in an environment where the temperature is too high or too low, using an inappropriate charging cable, etc., it will cause damage to the battery. Therefore, it is recommended to use the original charger and charging cable, control the charging time and frequency, and avoid long charging and frequent charging, which can extend the life of the battery.
Keeping your phone charged for long periods of time may also have some indirect effects on battery life. The following points are worth noting:
High temperature: A long charging process may cause the phone to heat up. If the phone is subjected to excessive temperature while charging, this may accelerate the aging of the battery. Therefore, it is recommended to ensure that the phone is in a well-ventilated environment when charging to avoid overheating.
Charging cycle: Smartphone batteries have a certain charging cycle. Each charge will consume a certain life of the battery, and excessive charging times may shorten the life of the battery. Therefore, if you connect the power supply for a long time just to be fully charged, you may increase the number of charges, which has a certain impact on battery life.
Although the mobile phone charging overnight will not damage the battery, but in the long run, the battery life will be greatly reduced, and even easy to cause circuit problems, so try to avoid charging overnight.
Overcharging for a long time will cause certain damage to the mobile phone battery. Although modern smartphone batteries have overcharge protection, overcharging for a long time may cause battery leakage, reduced battery life, and even cause fire and explosion safety risks.
Therefore, the following charging tips are recommended:
1. It is best to start charging when the battery power is less than 20%, and unplug and stop charging when the battery power reaches about 80%.
2. Try to avoid overcharging for a long time, especially charging overnight, which will cause great damage to the battery.
3. Use the original charger for charging, or use a brand certified charger to ensure the quality and safety of charging.
4. Avoid placing your phone in hot and cold environments while charging. High temperatures will cause the battery to decay faster, and low temperatures may cause the battery to fail.
In short, proper use and charging can maximize battery life and reduce safety risks.
It is actually unscientific to say that charging a mobile phone overnight is harmful to the battery, and the charging circuit of electronic products using lithium batteries, including smartphones, will automatically shut down after the battery is fully charged, without damaging the battery. On the contrary, \"dry\" the battery before charging, will shorten the battery life. Iphones generally don't overcharge, and charging a 90% charged iPhone won't damage the battery.
Although charging for a long time does not necessarily damage the battery immediately, bad charging habits will accelerate battery aging. Today's smartphones are basically using lithium-ion batteries, it has only a limited number of cycles, usually about a few hundred to one thousand times, fully charged batteries are easy to age at high temperatures, if it has been maintained charging state, it will also accelerate the aging of the battery, affecting the battery life.

Therefore, in order to extend the life of the battery, it is recommended to pay attention to the following:
< br >
1. Avoid overcharging, and unplug the charging cable when the phone is fully charged.
< br >
2. Avoid excessive battery consumption, such as closing unnecessary background applications.
< br >
3. Choose the original charger and data cable with reliable quality to avoid charging imbalance or other problems during the charging process.
< br >
4. Keep the phone battery temperature normal to avoid exposing the phone to high or low temperature environment for a long time.

In short, developing good charging habits can extend the life of the battery.
