Tips on cell phone battery and cell phone power saving &; Charging skill

With the rapid development of information in the 2 1 century, mobile phones, as the leader of information consultation, have occupied people's increasingly urgent lives with their unique communication functions. With the rapid development of science and technology, there are countless types of mobile phones and their functions are becoming more and more abundant. They can not only make phone calls, send text messages and send pictures, but also have various functions such as surfing the Internet, sending emails, chatting and watching online movies, which makes people feel a little at a loss.

However, even the best things will have shortcomings. The most troublesome thing is the mobile phone, because it takes as little as an hour or two to charge frequently, and as much as half a day and a night. If you don't replace the battery in time, the mobile phone may give you a "bad face" at any time, and many things will be ruined. Although with the further improvement of mobile phone battery technology, from nickel-cadmium battery to nickel-hydrogen battery, to lithium-ion battery and lithium polymer battery, the efficiency and capacity of the battery have been greatly improved. But it is difficult to determine how long a fully charged battery will last. In order to ensure the excellent performance of mobile phones during call and standby, and really get rid of the pain of power failure, we need to start with saving "traffic".

The short bell reminder function should be selected in quiet occasions. Generally, mobile phones have long and short ringtones. When using a mobile phone in a quiet place or in an environment with little interference, choosing a shorter ringtone setting can save electricity and reduce the interference of ringtones on the environment when incoming calls.

Play less mobile music and games. Listening to music and playing games on mobile phones consumes a lot of power. In particular, some enthusiasts always like to change a musical ringtone every once in a while, and it takes a long time to decide which one to use. Playing games when you have nothing to do is not worth the candle! In fact, isn't it better to entertain with walkman and handheld game machine?

It is best to use the vibration function when carrying a mobile phone in winter and spring. When the temperature is low in winter and spring, people often wear thick clothes. For example, they are carrying mobile phones outdoors at this time, and when a call comes in, the bell is often not easy to hear. As a result, the ringing time of the mobile phone is too long, and the connection rate of the mobile phone is also low, resulting in the waste of battery power. It's best to bring a mobile phone with the vibration function in cold weather. Less used outdoors or in cold places.

The lighting of LCD screen and buttons is not the best. When using a mobile phone, try to turn off the lighting function of the LCD screen and buttons to save electricity. In the season of long nights and short days, you should try to use your mobile phone in bright or well-lit places. In general, you can choose to turn off the lighting function of the display screen or mobile phone buttons to reduce power consumption.

It's best to turn off the phone in areas that are not covered by communication networks. In places with weak communication signals, such as indoors, especially in buildings made of concrete, such as shopping malls and cinemas, mobile phones desperately "capture" network signals, and batteries "flow" very fast, which will soon run out of battery power. Generally speaking, it is a waste to open a mobile phone in places where the communication network can't cover, the signal is weak or even can't be received. If you really need to use it, you can turn it on again in an area with strong signal, which saves electricity and can connect quickly.

Try not to use your mobile phone on the move. When you travel from one place to another by car or train, if you use a mobile phone, the battery consumption will be amazing. This is because the mobile phone moves from one network node to another, and when the mobile phone keeps searching for a connection to the communication network in a new area, the battery power is also slipping away quietly. At this time, if the performance of the mobile phone antenna is not good, it will be even worse.

Pay attention to protect the battery of mobile phone. Generally speaking, the adaptive temperature of mobile phone battery is 10℃-40℃, and it is best to use it in this temperature range. It is not conducive to the maximum efficiency of the mobile phone battery and the longest talk or standby time.

Make sure the signal transmission is unimpeded.

Some mobile phone users will easily hold the antenna in their hands when talking, so they should consciously leave a distance of 2-3 cm around the antenna as much as possible when talking to ensure smooth signal transmission and reduce the power consumption of the mobile phone.

Power saving mode is the preferred mode for digital mobile phone calls. Most models of digital mobile phones have advanced functions of DTX discontinuous transmission power saving mode. In order to save electricity, the power of transmitting radio waves can be reduced when the mobile phone is temporarily not talking. The actual measurement proves that DTX power saving mode can prolong the call time by 30%-50% at most.

Pay attention to maintaining the battery to prolong its life. Nickel-cadmium batteries in mobile phones are prone to "memory effect". The preventive method is to wait until the battery is completely discharged when the mobile phone is low-voltage alarm or automatically turned off, and ensure sufficient charging time according to the requirements of different models to prevent the battery from producing "memory effect". In addition, the "memory effect" can be eliminated by turning on the power of the mobile phone until the battery is completely discharged and then fully charged for more than three times.

Users who use mobile communication a lot should prepare several spare batteries. Some mobile users like to prepare a few extra panels, which can solve the urgent need, but beware of being fooled when buying additional panels. Fake mobile phone panels are very harmful to mobile phones, so how can we identify the authenticity of mobile phone panels? Here are some ways to introduce yourself:

① Look at logo: The logo printed on the real battery board is very clear, while the counterfeit products are copied and printed, and the handwriting is blurred. The "positive and negative" polarity symbols of the real battery panel are directly made on the metal contacts, and the fake ones are made on the plastic case, and some of them have no "positive and negative" symbols at all.

② Look at the process: the real battery panel is welded by ultrasonic wave, and the front and rear covers are inseparable without obvious cracks. Fake panels are mostly hand-made, glued together, and will split in half with a little force.

③ Look at the safety performance: In order to protect the battery and the mobile phone, the regular mobile phone battery panel is equipped with a temperature control switch. If the charging time is too long, the voltage is too high, the temperature rises sharply, and the battery panel heats up, the power supply will be cut off in time to prevent the battery from leaking or exploding. Fake and shoddy battery panels do not have this device, but are welded with an electric soldering iron, and even a small battery dedicated to non-rechargeable cameras is connected in series, while fake lithium batteries, if forcibly charged, may cause an explosion.

At present, mobile communication is growing at the same speed, and the amazing performance of information production needs to be further demonstrated. How to keep pace with the times and refuse to advance, there is only one answer: master first-hand information (information)!

Fourteen mobile phone battery charging skills that must be known

If users want to prolong the effective service life of batteries, besides ensuring the quality of chargers, correct charging skills are also essential, because inferior chargers or wrong charging methods will affect the service life and cycle life of batteries. The following are the charging skills compiled by the author:

1. Before the battery leaves the factory, the manufacturer is activated and precharged, so all batteries have residual power. Some friends say that the battery is charged according to the adjustment cycle, and the standby time is still seriously insufficient. Assuming that the battery is indeed a genuine battery, in this case, the adjustment period should be extended, and then the battery should be discharged by Wally for 3~5 times.

2. If the newly bought mobile phone battery is lithium ion, the first 3~5 times of charging is generally called the adjustment period, and it should be charged for more than 14 hours to ensure the full activation of lithium ion. Lithium-ion batteries have no memory effect, but they have strong inertia. It should be fully activated to ensure the best performance in future use.

3. Some automatic intelligent fast charging displays 90% full only when the signal light changes. The charger will automatically change to a slow speed to charge the battery. It is best to use the battery after it is fully charged, otherwise the service time will be shortened.

4. The lithium battery does not need special discharge before charging, and improper discharge will damage the battery. When charging, try to charge slowly and reduce the fast charging mode; The time should not exceed 24 hours. After three to five complete charge and discharge cycles, the chemicals in the battery will be fully "activated" to achieve the best use effect.

5. Please use the charger of the original factory or reputable brand, and use the special charger for lithium battery, and use it according to the instructions, otherwise the battery will be damaged or even dangerous.

6. Many users often leave their mobile phones on when charging. In fact, it is easy to hurt the life of their mobile phones, because the circuit board of the mobile phone will heat up during charging. At this time, if there is an external phone, it may produce instantaneous reflux current and damage the internal parts of the mobile phone.

7. The life of the battery depends on the number of repeated charge and discharge, so try to avoid charging the battery when the power is left, which will shorten the life of the battery. When the mobile phone is turned off for more than 7 days, the battery of the mobile phone should be completely discharged before use.

8. The mobile phone battery will automatically discharge. When not in use, the daily discharge of the Ni-MH battery is about 1% of the remaining capacity, and the daily discharge of the lithium battery is 0.2% ~ 0.3%. When charging the battery, try to use a special socket, and don't use the socket for household appliances such as chargers and televisions.

9. Although the mobile phone is in the network coverage area, it is no longer possible to answer and make calls when the mobile phone is turned off and charged. At this time, you can use the non-call transfer function of the mobile phone to transfer the mobile phone to the fixed phone around you to prevent the call from being lost. This method is also applicable when the mobile phone is not in the network coverage area or the signal is weak and temporarily unable to connect.

10. Don't expose the battery to high temperature or cold places, such as dog days, and don't expose the mobile phone to the sun in the car; Or take it to an air-conditioned room and put it in a place where the cold wind blows directly. When charging, it is normal for the battery to be a little hot, but it cannot withstand the "suffering" of high temperature. In order to avoid this situation, it is best to charge at room temperature and don't cover anything on the mobile phone.

1 1. Nickel-cadmium (N iCd) battery must be completely discharged before charging and fully charged after charging.

12. If the mobile phone battery is idle for too long, it is best to apply to the mobile phone maintenance department for charging the battery, or you can use the DC constant voltage device yourself, adjust the voltage to 5~6V and the current to 500~600mA, and connect the battery in reverse. Note: hair-trigger, repeat up to three times. After this treatment, the original charger is used for "adjustment period" charging.

13. When charging, the longer the better. If the battery without protection circuit is fully charged, it should be stopped, otherwise the performance of the battery will be affected by heat or overheating.

14. Special charger must be selected for lithium-ion battery, otherwise it may not reach saturation state and affect performance. Avoid putting it on the charger for more than 12 hours after charging, and separate the battery from the mobile phone when it is not used for a long time.

Distinguish the authenticity of mobile phone battery

1. The most common way to tell whether a battery is genuine or not is to look at its appearance. Usually, the surface color and texture of the original battery are clear, uniform and clean, without obvious scratches and damage; The battery label shall be printed with the battery model, type, rated capacity, standard voltage, sign and manufacturer's name. When using the mobile phone, the hand feel should be smooth and smooth, the tightness should be appropriate, the hands should be well matched and the lock should be reliable; Metal parts have no obvious scratches, blackening and turning green. If the mobile phone battery we bought does not conform to the above phenomenon, we can preliminarily conclude that it is a fake.

2. Identify the authenticity of the battery by checking whether the color of the battery is consistent with the appearance of the mobile phone. At present, many mobile phone manufacturers also strive to improve their technical level from their own perspective, so as to strengthen the counterfeiting difficulty of mobile phones and their accessories, thus further curbing the phenomenon of counterfeit parallel imports. General regular mobile phone products and their accessories must be consistent in appearance. Therefore, if we install the bought mobile phone battery, we should carefully compare the colors of the fuselage and the bottom case of the battery. If the color is flickering, it is the original battery. Otherwise, the battery itself is dim and may be a fake battery.

3. Use a dedicated detector to identify the battery. The quality of mobile phone batteries is difficult to distinguish between good and bad only from appearance. Therefore, a mobile phone battery detector has been introduced in the market, which can detect and judge the capacity and quality of lithium, nickel and other batteries with voltage of 2.4V ~ 6.0V and capacity 1999mAh, and has the functions of activation, charging and discharging. The whole process is controlled by the microprocessor according to the characteristics of the battery, and the digital display of the measured technical parameters such as voltage, current and capacity can be realized.

4. Judging by observing the abnormal charging situation. Generally, there should be an over-current protector inside the genuine mobile phone battery, which will automatically cut off the circuit in case of excessive current caused by external short circuit to avoid burning or damaging the mobile phone; Lithium-ion batteries also have overcharge protection circuits. When using non-standard electrical appliances, the power supply will be automatically cut off if the alternating current is too large, resulting in charging failure. Under normal circumstances, the battery can automatically return to the on state. If, in the process of charging, we find that the battery is seriously heated, or smokes or even explodes, it means that the battery must be fake.

5. Identify the battery by measuring the weight. Due to the light weight of lithium-ion battery block, it is generally around 100g; The weight of mobile phone battery blocks using Ni-Cd and Ni-MH batteries is above130g ... but the weight cannot be faked. Weight is an important method to identify counterfeit lithium-ion mobile phone battery blocks. Because weighing does not damage the battery block, the operation is simple and convenient, and it is an important method to identify counterfeit lithium-ion batteries and battery blocks.

6. Identify the battery according to the hardness of the joint. For Nokia 32 10, the appearance of this mobile phone is very different from other models, which brings great convenience to counterfeiters and of course brings trouble to our user identification. For this kind of battery, we should first identify the battery according to the hardness of the connector. We can press the joint of the battery arch, then press the battery hard and feel the hardness of the battery with our hands. Usually, the real battery feels soft and elastic. When installing the battery, we can easily connect the battery to the fuselage. On the contrary, because the fake battery itself is hard, when we install the battery, it will be difficult to install or asymmetric because of its lack of elasticity.

How to charge the mobile phone battery correctly

In addition to ensuring the quality of the charger, the correct charging method is also the premise to ensure the effective standby time and talk time of the battery. Inferior charger or wrong charging method will affect the service life and cycle life of the battery.

In addition, it is worth noting that the service life of mobile phone battery is not calculated by how long it has been used, but by the number of times it has been charged. Minimizing the charging times can prolong the battery life.

If the battery is newly bought or not used for a long time, fully charge the battery before use. When the Ni-MH battery is used for the first time, it must last for 12- 16 hours.

Before charging, the lithium battery does not need special discharge, and improper discharge will damage the battery.

When charging, try to charge slowly and reduce the fast charging mode; The time should not exceed 24 hours.

Please use the charger of the original factory or reputable brand, and use the special charger for lithium battery, and follow the instructions, otherwise the battery will be damaged or even dangerous.

After three to five complete charge and discharge cycles, the chemicals in the battery will be fully "activated" to achieve the best use effect.

Mobile phone batteries have self-discharge. When not in use, the daily discharge of the Ni-MH battery is about 1% of the remaining capacity, and the daily discharge of the lithium battery is 0.2 ~ 0.3%.

Determine your usage habits and choose the thick, medium and thin batteries that suit you. Generally speaking, the thinner the battery, the smaller the capacity, and the thicker the battery, the greater the capacity.

Clever calculation of mobile phone charging time

Nowadays, the number of mobile phone users is increasing rapidly year by year, but there is a question that everyone is generally concerned about, that is, how long should the mobile phone battery be fully charged? Many friends worry that insufficient time and battery power may shorten the service life of the battery; If the time is too long, it may damage the phone and battery. So how long should it be charged? Here is a simple calculation method:

Generally, the battery capacity is indicated on the battery, and the unit is mA. The larger the value, the greater the capacity. For example, 1200mAh means that the battery capacity is 1200mah. At the same time, the charger is generally marked with charging current, which is also mA. In this way, the battery charging time can be simply calculated as follows: the battery capacity is divided by the charging current, and then multiplied by the coefficient 1.2, and the time unit is hours. For example, if the battery capacity is 1200mA, the charging current of the charger is 600mA, and the charging time is (1200ma/600ma) *1.2 = 2.4 hours, then the charging time of this battery using this charger is 2.4 hours.

The above calculation method is not applicable to new batteries. Generally speaking, the first three charges of new batteries, especially nickel-cadmium batteries and nickel-hydrogen batteries, must be charged by machine, and the batteries must be fully charged for about 15 hours to maximize the service life of the batteries. The battery charging time can be calculated with reference to the above method in the future.
