The new phone charging mistake

Many friends believe that the new phone just bought the first three times to charge more than 12 hours, so as to maximize the battery life of the long. In fact, this concept is out of date. The so-called 12-hour charging activation battery is aimed at nickel-metal hydride battery, while the majority of smart phones on the market currently use lithium battery. Lithium battery does not need to be activated. There is no memory function, so it can be charged with, with the use of nickel metal hydride battery so much attention.

If you want your smartphone to maintain the battery life it could have achieved, you might as well charge it in the following ways:

1. The first three times of the new phone can be used with low electric alarm, and the phone can be fully charged with the original direct charging device when it is turned on, and then it can be charged for an extra hour, which is recommended considering the error of charging control, and it does not need to be charged for 12 hours.

2, many people like to go to bed to charge the phone, in fact, this will lead to the phone charging time is too long, so that the phone battery will cause some damage. In addition, in many areas, the night voltage is high and fluctuates greatly, which has no positive effect on the maintenance of battery life.

3. General smart phones on the market can be charged, used and stopped at any time. Don't wait until the phone is completely dead and automatically shut down before charging, which is also very damaging to the battery. The battery can be recharged for 15-30 minutes after recharging.

In fact, the smart mobile phone use is lithium battery, it is not you imagine so fragile, when cell phone batteries, charging power supply is cut off automatically, to avoid overloading the overcharge, so don't worry about the battery damage, also need not up and pulled out the power supply in the middle of the night, the user can set his mind at to sleep a good sleep!

Of course, it should be noted here that the use of mobile phone charger must be a regular charger, preferably the original charger. Some fake or mismatched chargers are better not to be used at night to charge mobile phones, to prevent poor quality chargers, chargers burn out and damage mobile phones.

Lu Jianguo, director of the comprehensive inspection department of the national household appliance quality supervision and inspection center of the Chinese academy of home appliances, told the life times that different battery products need different methods to charge and must be used according to the product description. Early nickel-cadmium and nickel-hydride batteries required similar "activation." These batteries will produce a "memory effect", charging in the state of incomplete discharge, easy to overcharge the battery, for a long time will let the user feel that the power will be used up soon. But today's phones and laptops are powered mostly by lithium-ion batteries. Its initialization process is completed at manufacturing time, so activation is not required when it is first used.

Lithium ion battery life can reach hundreds of charging and discharging cycles, the charging and discharging cycle refers to the process of charging and discharging the battery after it is used up, rather than plugging in the charger and unplugging it once. Lithium battery has no memory effect and can be charged at any time. In order to reduce the number of charges, deliberately recharging the battery after it is used up does not extend the battery life, but has a negative impact on the battery life. In addition, if the mobile phone is automatically turned off, the lithium battery will be too low internal voltage due to excessive discharge, and may not be able to start up and charge. Accordingly, lithium battery is charged pay attention to "eat less much meal", frequent shallow charge discharge is helpful for prolonging its life more.

Lithium battery generally has a safety protection circuit and a variety of safety devices, to ensure that in the excessive charge and discharge and short circuit automatically cut off the circuit of the battery; Excessive pressure inside the battery will also trigger the exhaust device to reduce pressure; If the battery temperature is too high, the hot melt protection device will be triggered, thus stopping the electrochemical reaction of the battery. Therefore, unless there is a quality problem, the battery will not explode because it is plugged in for a long time. However, if you do not unplug the power supply after it is fully charged, the battery will remain fully charged all the time. Although it will not explode, it will accelerate the loss of battery capacity.

In addition, there are rumors that answering a phone while charging can cause an explosion. 'this argument doesn't hold water,' Mr. Lu said. 'if there is such a danger, the product will be programmed not to connect to the phone while charging.' However, from a health point of view, the power line will limit the user's range of movement, while charging to make and receive phone calls, may let the user stay in one place for a long time, resulting in excessive muscle tension, so it is recommended that it is better to unplug the power before talking. Do not cover anything on the battery when charging, and do not put it on the bed to avoid fire.

It depends on what battery you have. Like there are lithium batteries

First of all, repeated charging will not damage the battery. Repeated charging and discharging will basically do no damage to the battery. Lithium is more active and has no memory effect, so batteries made of lithium can be repeatedly charged and discharged. Most of us (more than 90%) are still thinking in the shadow of Ni-Mh batteries that were popular a few years ago, because nickel itself is inactive and the element has a memory effect on electrons, that is, the depth of the last charge and discharge. Therefore, if the battery is not used up or charged for a long time (full activation of nickel - due to its inactivity), the best charging effect cannot be achieved, so the charging time is generally in one night or more hours!

However, we now have lithium element, the element in nature can exist independently, can only exist in compound, you can refer to the periodic table, lithium half-life is very short, and no memory effect, so the lithium battery in use process cannot be rushed electricity for a long time and completely discharge, because of long time charging will make itself is a very active element in an intense movement occurs under the condition of saturation, at the same time with explosion, namely: Best for 2-4 hours charge time, had better not more than 4 hours (element is more active, charging arouse quickly, charging time and the corresponding shortened, even for the first time charge is just 2 hours to 4 hours, because lithium is no longer need to activate, charging for a long time instead of influence in the activity in the process of charging and discharging lithium), by the way of lithium battery charging process, we will be in the process of charging in an hour and a half or two hours found already full, at this time of half an hour, again because the charging is finished first voltage, then is the electronic charge, for about half an hour late! When using electricity, it is also better not to completely use up the recharging, because the lithium required by the reverse reaction required by the compound is insufficient, cannot be fully charged, resulting in a drop in the battery capacitance!

So,

1. Charging time: 2-4 hours (not too long, long time will seriously affect battery life and risk)

2. The first charge should not last long, just like the regular charge (don't go into the nickel metal hydride battery mistake).

3. It is not possible to completely run out of the electricity (completely used, also has a serious impact on the battery life). The number of times a lithium battery can discharge deeply is only a few times, and more is not good

4 in the process of use, see fast no electricity, feel not enough to rush, can be full of the best, it does not matter to rush dissatisfaction!

Charge while using. This is the slogan of the inventor of lithium battery. If charging is so troublesome as nickel metal hydride battery, who can invent lithium battery that is much less stable than nickel metal hydride battery? The convenience that still valued lithium battery mainly!
