The battery is recharged or not recharged

It is better to use up the original battery and recharge it to the mobile phone battery.

The first few times you buy a mobile phone, charging is very important.

It is related to the life and durability of your mobile phone battery in the future.

The money must be charged for more than 12 hours several times.

Lithium batteries can be charged casually, no matter how many points are left, you can charge them again!

However, you must pay attention to safety when using your mobile phone, and do not call while charging**! Don't put your pillow at night!

Well, lithium batteries have no memory effect and can be charged at any time, in order to reduce the number of charging times and deliberately use up the battery and then fill it, it can not extend the battery life, but has a negative impact on the life of the battery. In fact, lithium battery charging pays attention to "eating less and eating more", and frequent shallow charging and discharging will help to prolong its life.

Try to use up the battery of the phone, preferably to the automatic shutdown, this practice is only suitable for nickel batteries, in order to avoid the memory effect. At present, most mobile phones on the market use lithium batteries, and its rechargeable times are closely related to the depth of discharge of the battery. Lithium batteries lose a lot when they are at a low charge, so waiting until the power runs out before recharging will speed up its loss.

Staying at 40% to 60% for a long time can make the battery last longer.

Precautions for mobile phone charging:

Do not recharge after a full charge. If your phone is fully charged but still connected to a power source, it will affect your battery life. This is because, once the phone reaches 100% charge, it goes into "trickle charging."

Mode - Maintains a fully charged state. If you continue to charge, the mobile phone battery will be affected by the current, and some chemical components will be destroyed, affecting the use efficiency.

Do not charge to 100%. In fact, lithium batteries do not need to be fully charged and then de-energized. This is because, when the phone is fully charged, the voltage inside the battery will rise, increasing the burden on the battery. Therefore, the mobile phone can be plugged and unplugged at any time, as long as it can maintain normal use.

You can connect your phone to your phone at any time. Many people are used to charging their phones after the battery is depleted, but in reality, the phone can be charged at any time as long as there is a power source. This is because lithium batteries are commonly used in mobile phone batteries, and multiple plugging and unplugging of the power supply will not affect the battery.

Studies have found that charging is best when the phone is 10% drained.

The phone is the best to charge when it doesn't run out of power.

In fact, for the power of the mobile phone, the battery power is between 30% and 80% for a long time, which is the best protection range for the battery. If you use your phone in this power range for a long time, the battery life will be the longest.

The idea that we should run out of battery and recharge our phones is actually wrong.

For mobile phone batteries, there is a fixed life, a complete charging and discharging process is counted as a life, the battery life of a mobile phone is about 500 times, then after each completion of the life cycle, the original capacity of the battery will decrease, so there will be a situation where our mobile phone battery life is getting worse and worse. For lithium batteries, it is chemically active, like many digital products now, if we do not use it for a long time, we will have to charge it for a long time when we use it again, and we may need to replace the battery directly. That is to say, if the battery level of the mobile phone is too low, the chemical activity inside the lithium battery will be harmed, of course, the lower the battery, the greater the damage.

The best way to take care of your phone's battery:

It is not completely discharged and recharged, but the phone should be charged and used without heating and maintain 40%-80% of the power, it is best to turn off the program as much as possible during the charging process, if the phone is not in use, it is best to switch the phone to airplane mode, so that our battery can be more durable. <>

No. Our common batteries are not capable of charging, that is, the batteries we commonly use are disposable batteries.

When we use up the power, we can't recharge it for reuse, because our common acid battery can't carry out the reduction reaction when the energy in it is completely discharged.

If the battery cannot be charged, then it must not be charged, otherwise the battery may endanger personal safety.

A rechargeable battery is a rechargeable battery that can be charged a limited number of times and is used in conjunction with a charger. No. 5 and No. 7 are generally sold in the market, but there are also No. 1s. The benefits of rechargeable batteries are economical, environmentally friendly, sufficient power, suitable for high-power, long-term use of electrical appliances (such as walkmans, electric toys, etc.).

The voltage of the rechargeable battery is lower than that of the disposable battery of the same model, the AA battery (5 gauge charge) is volt, and the 9V rechargeable battery is actually volt. Now the general charging times can be about 1000 times. As of February 2012, there are only five:

Nickel-cadmium, nickel-metal hydride, lithium-ion, lead-storage, lithium iron.

If it is a mobile phone, it is not recommended to charge the battery after all the batteries are cleaned, because this still has a certain impact on the life of the battery, and it is normal for us to use the battery to about 20% when it is best not to charge the mobile phone.

The battery is well charged to 80.

The phone should be unplugged as soon as possible when it is fully charged. Some people think that charging is as long as possible, but they don't think so. If you don't pull out the power after being fully charged, the battery will always be fully charged, although it will not **, but this will accelerate the loss of the battery.

No need to keep 100% charged. In fact, the battery is the same as people, they don't want to be stressed, so don't always fully charge the battery, in fact, Zheng Hao's general brother can withstand about 80% of the power, and the power at this time is more durable in terms of battery life.

Principle. The battery receives electrical energy from the external circuit and converts 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.

According to the formula of electricity = voltage * current * time, in the case of fixed power, the charging time can only be shortened by increasing the voltage or increasing the current.

As long as the battery of the mobile phone is fully charged, there is no need to recharge it in the field, we can unplug the charger, and we can continue to make the Yufeng shout when the power is used to about 20% of the time base to wait, start charging it, full of this, it is still helpful for the life of the mobile phone battery.

When the mobile phone battery is full, unplug it in time, instead of charging it in a row.

In the case of overcharging, it will hurt the battery very much and shorten the battery life.

Therefore, when the battery is full, don't continue to charge it.

It's better not to charge it properly.

Most friends should believe that it is better to wait for the smartphone to run out of power and then charge, because most of the previous mobile phones used nickel-metal hydride (NIH) electric sun car lack pool, nickel-metal hydride battery charging has the so-called charge-discharge memory effect, if not used and recharged, it will lead to a shorter battery life, so their opinion is right, that can only be applied to the previous mobile phone. And now there is no need to wait for the power to run out and then charge, because the current smart phones are basically lithium batteries, lithium batteries have no memory effect, but if you wait until the power is used up and then charged, it will affect the chemicals in the lithium battery can not react normally and shorten the battery life. Many people have heard of the Samsung mobile phone battery ** problem, do not like to charge at night, afraid in case there is something, in fact, this worry is redundant, now the smart phone lithium battery will automatically cut off the power supply after being fully charged, to avoid overload charging, so now the mobile phone is generally full, will automatically cut off the power, and there is no big problem at night.

Precautions for mobile phone charging:

1. Please unplug the mobile phone in time after it is fully charged, the mobile phone will be in a high power state for a long time, which will cause the loss of the battery to accelerate.

2. It is recommended that you try to avoid waiting until the battery level is lower than 20% before charging the battery, as over-discharge will cause the loss of the battery to accelerate. It can be charged as you go to prolong the life of the battery.

3. Please do not leave the mobile phone idle for a long time, and fully charge the battery from time to time. If the phone is not used or charged for a long time, the battery will be completely consumed, which will lead to abnormal charging or failure to charge. <>
