How to prevent cell phone lithium battery heat up

Recently, Haikou continued high temperature, and mobile phone  also heats up. Many residents said that mobile phones are particularly hot in the summer and even hotter after being generally used for more than 10 minutes. And many people reported that the high temperature of mobile phones will not only slow down the mobile phone system, power consumption, and at the same time, if your face is closed to the mobile phones for a long time, it will cause dizziness and so on. Why and how do we solve this problem?

What makes the phone so hot?

First, a touch phone, the mobile phone to determine which position is the hottest. See the battery phone is hot, circuit board. If the battery is hot, so it may have problems. Batteries often appear to lack power consumption, power consumption speed, battery preparation is the best. It is important to note that as soon as the battery expands, the battery is updated.

Secondly, check the mobile software. Cell phone power screen, coupled with excessive power consumption of mobile software, caused the phone to heat up. You can also download a test software for mobile system power consumption.

Third, to determine whether the phone has a percussion sound, or into the water, causing the phone short circuit, making the phone hot.

Fourth, the use of high material density can also lead to poor heat dissipation, leading to abnormal heat. After excluding the above questions, the problem of mobile phone fever should have played this role.

8 to treat mobile phone "hot"

1. Avoid long-term use above 30 °C. Used for high temperatures that can not even run simple working heat dispersion, causing trouble. So be careful not to use your phone in hot places like the sun or heat. In particular, do not play games and social software, and do not play video. Because these use download traffic, more and more use data processing is large, it is easy to increase CPU load data processing. At this point, even a completely fine operation in a cool place can cause abnormal heat.

2. Do not put more than 45 ℃. The temperature limit of the mobile repository is 45 ℃. For example, closed cars may reach temperatures above 45 °C. But out in Hainan, at 40 degrees, remember to keep your phone in your car. Because of long exposure, room temperature can cause heat, which can lead to shorter typesetting or explosion.

3. Don't use your mobile phone in the sun. If the phone is exposed to sunlight, the temperature suddenly rises, causing abnormal heating. In addition, long-term exposure to the sun can cause damage, liquid crystal displays will partially appear light color, and even lead to the display being burned.

4. Remove dust earphones and external microphone holes, possibly because of dust clogging the earphones and external microphone holes, causing the heat inside the phone to accumulate. So pay attention to dust cleaning.

5. Be careful not to put it near your body. The cell phone keeps spare things in its pants pocket, such as storage, where it sweats and swallows the same state. Because sweat contains salt, it is more likely to damage the floor than pure water. Water and joints are also easily short-circuited when charging, making them hot.

6. Stop using the phone if you have a fever. When the handheld phone feels a fever, do not use it, turn it off and let it shut down automatically. Because when the mobile phone fever continues to use, inflation is likely to cause the main board to fail.

7. Don't cool down quickly in front of the refrigerator or air conditioner. There will be a sudden drop in the temperature of the hot phone, and the difference in the external air and temperature inside the phone will produce a condensation reaction, which will be soaked in water and short-circuit heat on the motherboard.

8. Mobile phones produce heat every day at work. They should have computers, televisions, and other household appliances at home. Occasionally, they cut off the power to give it a good rest.

Risk of cell phone battery heating

The power consumption of a mobile phone calling or using MP3 is very large, that is, the equivalent load resistance of its battery is very small, when the work is a large current discharge. The current required for mobile phone work can not be reduced. Therefore, a considerable part of the energy consumed by the battery's internal resistance causes the battery to heat and discharge faster, shortening the battery's service time. They are very fast. The dangers of cell phone battery heating are as follows:

1. Mobile phones battery long time heating can lead to internal parts fever, enabling to reboot or hang up the phone call

2. The battery long time heating will increase the heat of the battery itself, if it is sealed (such as NOKIA is not sealed, is directly to the battery into battery will make its internal air dramatic expansion, lead to the battery as vegetative, serious can make battery explosion.

3. The battery long time heating aging process will accelerate the phone itself, shorten its life.

Mobile phone battery fever prevention and solution

A, prevention methods:

1. The phone in normal room temperature, heat less than 60 ℃ is a normal phenomenon, will not damage the battery.

2. The use of large current charger time should not be too long, too long charging can make the battery is damaged, it will also generate heat.

3. The charger it is best to use the original or better reputation for quality products.

4. If you don't hurry to use, suggest or charging seat charger (slow filling way) as well, not make the battery heating.

5. The use of mobile phones while listening to MP3 or battery such as feeling a bit hot, such as more than 60 ℃ immediately return to standby mode or in piece of battery, such as in charge immediately unplug chargers.

Second, the solution:

1. If the battery has been filled out, also can work it out. The gap is to use your fingers to find battery (cell phone battery back close to the mobile phone charge electrodes, press down a bit soft), use for to poke a hole and let the air out.

2. Throw it and buy another battery.
