Is frequent and short charging bad for the battery

The phone battery is charged frequently.

Will frequent charging of mobile phone batteries shorten the life of mobile phone batteries? Now the smartphone battery basically runs out of power after playing games for a few hours, and some people play games or surf the Internet while the phone is charging, in fact, the life of the mobile phone battery lies in our usual charging habits, and developing good charging habits can extend the battery life.

It is undeniable that lithium batteries also have a memory effect, but its memory effect is minimal, and even the manufacturer ignores this memory effect. However, in actual use, you may find that the time for lithium batteries to be used will become shorter and shorter. What's going on?

In fact, the material used to make lithium batteries is an active substance, and the active substances will age.

The materials used to make lithium batteries are sensitive to the degree of frequent charging of mobile phone batteries and the use environment, temperature and other conditions. Generally, the service life of lithium batteries is 300 500 times of charge and discharge, and the natural loss of the battery will significantly shorten the continuous use time of the battery. Excessive charging and excessive discharge will rapidly reduce the battery activity, which will directly lead to the rapid aging of lithium batteries.

Many mobile phone users may have this experience, obviously showing that there is still a grid of power, but after half an hour, it will display "low battery", and sometimes it will automatically turn off. Therefore, we usually use it frequently, and the battery is charged frequently, which will accelerate the aging of the mobile phone battery to maintain the integrity of the charging time, do not often use the mobile phone while charging, and charge it for one to two hours after being fully charged. Recharge when you're done with power.

Try not to use a universal charger!

In addition, do not expose the battery to high temperatures or severe cold, such as dog days, and do not put the mobile phone in the car to withstand the scorching sun; Or take it to an air-conditioned room and put it in a place where the air conditioner blows directly. When charging, it is normal for the battery to be a little hot, but it should not be allowed to withstand the "torment" of high temperatures. To avoid this, it is best to charge it at room temperature and not cover anything on your phone.

Lithium-ion batteries must be equipped with special chargers, otherwise they may not reach saturation and affect their performance. After charging, avoid placing it on the mobile phone charger for more than 12 hours, and separate the battery from the mobile phone when not in use for a long time. The use of well-known brand mobile phone batteries, domestic smart batteries or millennial business batteries and chargers are the same, with a limited lifespan, so try to save the power of the battery, which can prolong the time of mobile phone battery use.

I am a professional battery maker, and this problem can tell you with certainty that there is no problem. Lithium batteries do not have the so-called memory effect, so there is no need to charge when the electricity is used up, but charge it when there is time, so that it can be kept in a relatively normal state of charge, which is beneficial to its life.

Of course, there will be a certain impact, which will shorten the service life of the mobile phone battery; Mobile phone charging, charge for a while and pull for a while, occasionally this has little impact on the mobile phone, but the mobile phone battery generally has a limit on the number of charging times;

In fact, you are reducing the number of times the battery is charged, in other words, the service life of the mobile phone battery will be greatly shortened, so when charging, it is necessary to unplug it when it is full every time, which is the most scientific way to charge.

Extended Information: The Right Way to Charge Your Phone:

1. Whenever the mobile phone has a power prompt, most of the mobile phone power is 20% at this time, indicating that the hand phone is already short of power, and the mobile phone should be charged at this time. And if the power is less than 20%, it is also harmful to the mobile phone battery.

2. Non-flammable limbs should be used while charging, and it is best to turn off and charge, which is the best maintenance for the battery.

3. The charging time should not be too long, and it can be fully charged. Although today's mobile phones are protected by circuits, the mobile phone will heat up when connected to the charging terminal for a long time.

Continued high temperatures can affect battery life and even be dangerous.

4. The first charge does not need to be too long, and now Kaimo's batteries are lithium batteries or polymer lithium batteries.

There is no such thing as a memory effect. So the first charge of the phone only needs to be the same as usual.

Now it is different from the previous battery, the current battery likes to charge at a high frequency, and it is the harm to the battery when used to the limit.

To be clear, most of them are lithium-ion batteries now. There is no such problem at all, it is all charged as you go.

I just don't like fast charging, if it's fast, it's really good; There should only be fast left.

After the phone is fully charged, will it hurt the battery if it continues to charge for an hour? You have to tease Qin to know these 4 points!

Charging the phone for another hour after it is fully charged will not harm the battery, provided that you use a charger and charging cable produced by a regular manufacturer that meet the national 3C standard. At present, our smartphones have intelligent detection circuits for battery voltage and current.

According to the current charging technology, mobile phones can be charged with high current when the mobile phone battery is low, and when the battery of the mobile phone reaches a relatively high level, the current will begin to be reduced until it is fully charged.

When the battery is fully charged, the detection circuit will cut off the circuit between the phone and the charger, and the charger will no longer be able to charge the battery, so today's smartphones don't have to worry about overcharging the battery.

However, the above process also requires that the charger and charging cable are produced by regular manufacturers that meet the national 3C standard.

Regular manufacturers of chargers and charging cables can ensure quality, some copycat manufacturers produce products do not dare to say, it is not recommended to save a few dollars to take risks, a mobile phone is much more expensive than chargers and charging cables. There are also those miscellaneous brands of power banks, and it is not recommended to use them to charge mobile phones.

Of course, there are some caveats:

1. Don't charge until the battery is exhausted, you must charge it when you use about 20%. In fact, charging before the battery runs out is not only not damaging to the battery, but better for the battery.

2. Whether the lithium battery is used or not, the "shelf life" is 3 years, and it decays quickly after three years. After 3 years, it is best to replace the battery, or directly replace the phone.

3. In addition to being afraid of low power, lithium batteries are also afraid of overheating, especially when charging in hot days. It will heat up when charging, so it's best to take the phone case off while charging.

4. In addition, mobile phone users should pay special attention to the fact that in the process of charging the mobile phone, do not play games or other large-load use, the reason is not because of large power consumption, but will produce a lot of heat, shouting at this time you will feel that the mobile phone is very hot, which often reduces the battery life.

For most smartphones, long-term charging will not have an impact on the battery state, and smartphones generally have a power management chip inside, and the phone will automatically power off when fully charged.

Tips for using mobile phones: 1. If the mobile phone cannot be charged or the charging speed is slow, the power cord may be damaged and the data cable needs to be replaced; It may be that you did not use the original charger to charge the phone, and it is recommended to use the original charger to charge the phone.

2. Mobile phones generally have a power-saving mode, open the system settings page of OnePlus 7, click on the battery option, and turn on the power-saving mode, or you can turn on the power-saving optimization function.

3. The battery type of the mobile phone is generally a lithium battery, if the battery cannot be used, it is recommended to use the official battery. Sail Notice.

4. Huawei P30Pro supports wireless reverse charging, which can charge AirPods and other devices.

Data expansion: mobile phone battery is an energy storage tool that provides power for mobile phones, which is composed of three parts: battery cell, protective circuit and shell, lithium-ion battery has no memory effect, but it is inert, and there may be passivation phenomenon if it is not used for a long time, and when the device is charged together in some styles of protective shells, it may generate too much heat, thus affecting the battery capacity.

If you find that your stove gets hot while charging, please remove the protective case first.
