Is there any difference between mobile phone battery charging, standby charging and taking a univers

First, the direct charge is specially made according to the mobile phone, and the universal charger is very hurtful to the electric board, the universal charger current and voltage are not standardized, and the charger is always not standardized, which is very harmful to the life of the battery.

Second, the correct way to charge the mobile phone:

1. The charging time is 3-4 hours is the most appropriate, and it can be fully charged, and the battery life will be seriously affected if the time is long.

2. The first charge does not need to be fully charged for 12 hours, this is an old-fashioned battery practice, and the first time it only needs to be charged as usual.

3. Do not use photoelectric completely, and completely use up the power of the mobile phone, which has a serious impact on the battery life.

4. It is best not to use universal charging, the universal charging current is unstable and the quality is uneven. And try to use the original charger when charging, so that the speed will be faster.

Almost, it is known that the standby flushing time is very good, 2-3 hours is good, and the universal needs more than 5 hours to be full.

First of all, the best way to charge the mobile phone battery is to turn it off and charge it with the original charger! The first 3-5 times of battery use strongly require such a charge! And to charge for more than 10 hours, in the process of use, this kind of charging brings us a lot of inconvenience!

So it usually doesn't matter after the first few charges! This effect is to completely activate the battery, so that the life of the battery is greatly increased! In ordinary use, it should be noted that the discharge should be clean, the best charging, the original charger plugged into the mobile phone, the best charge, generally more than five hours!

Why some people's original batteries can last for 2 years, why some people's original batteries can't work in a few months! The mystery is there! Remember: Don't charge the battery while playing ** and surfing the Internet Charging while using it is the fatal weakness of the battery!

It is better to charge it with the original charger It is better for the battery!

In fact, for the mobile phone battery, it is also very important to use what charger to use, and the premise is that the mobile phone battery must be guaranteed to be the best.

Generally speaking, it is better to charge mobile phone batteries directly with the original mobile phone, if there is no rolling mold or replace a brand of Zhichang battery, it is best to use the brand's charger for charging, whether it is direct charging or universal charging, because the batteries produced by the same manufacturer are generally matched with the charger, and the prenatal trial production must also use their own batteries to do experiments, so it is more assured, do not go to the market to buy some miscellaneous direct charging or universal charging for the first mobile phone battery charging, This will not only damage the phone's battery, but also may be dangerous.

With direct charging, the mobile phone you just bought must be charged after all the batteries are used up, otherwise it will hurt the battery.

The universal charger is not good for the battery, which refers to the inferior universal charger. If it were that bad, there wouldn't be a widespread product.

1.Batteries are usually limited in charge current and voltage. Some fast universal chargers can fully charge a battery in two or three hours, and such a large charging current will inevitably cause damage to the battery.

2.A good universal charger provides trickle protection and overvoltage protection, and can provide the same charging current and voltage suitable for the battery as the original wire charger, and the damage to the battery is little or nothing.

For example, I have two batteries in use, one original electric and one scud. It's all a scud's all-purpose charge. The original power has been used for 2 years, and the standby is still about 3 days.

The battery of the Scud lasts 1 year and standby in 4 to 5 days. I think that's telling.

Listen to the professional: universal charger, also known as fast travel charger, is convenient! It can only charge 60%-70% of a battery, although the display is full, but it is not 100%, and the battery can only be charged to 60% if used regularly, all of which have an impact!

But occasionally it doesn't have much of an impact! Hope it helps!

Universal charging battery, I have 2 Nokia batteries, and now it will be out of power in 1 day when it is more than **, if you want to protect the battery, you should buy it straight.

The universal charge is designed to facilitate the charging of all batteries, so the design of the current and voltage is the minimum standard, while the direct charge is specially designed for the corresponding battery, so the direct charge will of course be better than the universal charge.

From the perspective of the quality of the battery, the universal charging power is low, the charging time is large or long, there is a greater risk (such as voltage instability, etc.), and the universal charging battery is repeatedly rubbed against the contact piece, which may lead to a decrease in battery contact performance, and long-term use will lead to a decrease in battery life.

All batteries have a fixed service life, and it is inevitable that they will not be able to continue to be used after a certain number of charges, which is not the fault of the universal charge, but the universal charge may lead to a decrease in this number.

It is best to use the original charger for mobile phones, the universal charger will not only affect the battery life of the mobile phone, but also the battery capacity of more than 18oomah universal charger will also reduce the life If you are a family of time, it is no problem to change the mobile phone frequently, the universal charge is convenient and fast!

Not good, very bad. Inferior universal chargers will shorten the life of the battery and may be dangerous. It is recommended to use the original charger.

Very bad. There is a lot of damage to both the battery and the phone. Recharge the battery with a universal charger. It's been a long time to charge. Yes, the battery is charged. Dumbfounded. That is, the battery is broken.

It's not good, it's easy to break the battery, the universal charge is generally not produced by well-known manufacturers, there are messes, short circuits, or something. . .

In fact, the universal charge has a great loss on the battery, and it is easy to shorten the life of the battery.

Conclusion: Not good.

Reason: 1. Charging effect. Some automated smart fast chargers (universal chargers) actually only indicate that they are full of 90 when the indicator light changes.

The charger will automatically change to fully charge the battery with slow charging. Don't cut off the power of the charger immediately, it's best to give the battery a period of time to recharge, and then use it after the battery is fully charged, otherwise it will shorten the use time.

Second, safety performance. There are protection circuits inside the charger, and the charging protection circuits of different mobile phone batteries are different. And some universal chargers cannot set up protection circuits for all mobile phones. A long time is also very harmful.

It can be charged, but it is not recommended to use a universal charge.

Universal charging has good compatibility, but in order to produce qualified products, special computing chips and testing circuits must be used, and the comprehensive cost of such products is not 100 yuan, don't want to win. What new technology is used in the "universal mobile phone charger" that sells for dozens of yuan (the actual cost is probably less than 10 yuan) can automatically provide the appropriate current and suitable threshold voltage according to different batteries, so as to achieve universal efficacy.

A closer look at the "universal phone charger" reveals that it only has two output wires, while knowing that a well-designed charger has at least three outputs. The two in the middle of the battery are generally data feedback lines and temperature and alarm lines, and most lithium-ion batteries have protection circuits and even intelligent management chips inside. "Only two output lines" means that the charger has given up the protection circuitry that the battery itself has.

Only in this way can the "cheap omnipotence" be realized

Many chargers with low manufacturing accuracy use the method of lowering the cut-off voltage (the normal cut-off voltage is . They set the threshold normal distribution to about 4V. Doing so makes the charging itself safe, but the battery is never fully charged.

This is equivalent to a decrease in battery capacity, which leads to an increase in the number of charges, which also leads to a reduction in battery life.

Lithium-ion batteries are very squeamish and sensitive. The charging and absorption efficiency of lithium-ion batteries is almost 100%, and whether it is overcharging at a high current or overcharging at a small current, it can cause the battery to fail. Therefore, battery threshold control can be said to be the key to charging control, in summary, when the battery capacity of smartphones is generally large and expensive, it is not recommended to use universal charging.

Batteries are all have a certain lifespan, and the universal charger should be designed to take into account the versatility, so the charging voltage set is rated, so it may not be suitable for your mobile phone battery, and the production threshold is too low, resulting in uneven quality, so it is best to charge with a special charger if there is a special charger.

Because it is an assembled battery, it will explode when charged with a universal charge The merchant said this because you buy a mobile phone battery in his store and the battery also has a warranty.

The universal charge has no memory function, there is a certain damage to the battery, for convenience, it is okay to use occasionally, but no matter what battery is charged, it can be charged for 2-3 hours at most, although the display is not full, the actual universal charge, how long it will not be full, the charging time is too long, the battery will be more harmful, and there will be overcharging.

Mobile phones are recommended not to use universal charging as much as possible, licensed mobile phones** Ouku is also introduced in this way, or listen to the dealers and manufacturers.

Magnum has a variety of brands and models, and good or bad cannot be generalized. It is best if you can determine the basic performance of this universal charge, the main point is the accuracy of voltage breaking, including temperature, whether there will be fluctuations when the mains voltage changes, the charging cut-off voltage of lithium battery is generally required not to exceed, and it is generally guaranteed by a special charging management chip, otherwise it is best not to use it.

The reason why it is called universal charging is because it charges the battery with the most basic charging conditions and universal charging curve, ignoring the personalized requirements. For lithium batteries, it is to use the conservative charging current and charging cut-off voltage, while ignoring the judgment of battery temperature, power, personalized cut-off voltage, etc.

The reason why these factors can be ignored is that the current of the universal charge is generally small, such as 500 700mA, and for most of the current batteries with a capacity of more than 800mAh, it will not cause the problem of excessive temperature.

For the special charger, for example, it can be said that the mobile phone itself or the supporting dock charger is a special charge, which can be accurately set according to the performance of the battery, the charging cut-off voltage is appropriately higher than the higher current can be charged to achieve the purpose of fast charging, so it is necessary to accurately detect the battery temperature, power, etc., to ensure that it can be charged more fully without damaging the battery.

For a 2000mAh battery, the general regular universal charge only has a slow charge, and it will not charge the battery, but according to the standard of accurate filling, it is not good.

Whether the universal charger can be matched with this battery in terms of cut-off voltage, it is best to make a measurement, that is, first use a special charge (or mobile phone) to fully charge, then remove the battery, use a multimeter to measure the battery voltage as a standard and remember; Then the next time you charge the lamp with a universal meter, you can also use a multimeter to measure the voltage of the battery, which is not higher than the special charge, and there is no problem.

The charging curve is different, which is easy to cause battery damage, and the gains outweigh the losses. Of course, except for the Zhaiji.

More than 2,000 mobile phones, with more than 10, you can rest assured? The batteries are more than 90.

It is not recommended, because the charging curve is really different, easy to break, batteries of different capacities, the curves are different, universal charging, generally only a simple voltage test function, the knife will be powered off, but the voltage characteristics of polymer lithium batteries are not obvious, or not charged, or not full.

It is best not to use a universal charge, the battery that can be charged by the universal charge is easy to bulge, and the life will become shorter. It is best to plug in the cable directly and charge directly.

Okay, otherwise, what else will the universal charge do, it's been going to be okay for n years.
