As a novice, you should read the instructions carefully before using the mobile phone, especially pay attention to the precautions in the instructions. There is a lot of knowledge about mobile phone maintenance. The maintenance of mobile phones generally has the following parts:
First, the maintenance of mobile phone batteries
The maintenance of mobile phone battery should start from the first charge. The first charge has a great influence on the service life of the battery in the future. Generally, the first charging time is required to be 16 hours (if the battery is fully charged, it should be used up first), but remember not to exceed 24 hours, otherwise the battery may be fully charged. After charging, it is required to recharge after each use for about 5-6 hours each time. For a new battery, it needs to be charged and discharged many times to achieve the best use effect.
It should be noted: Do not charge the battery when it is half used or the used battery suddenly stops using for several months. The standard service life of a battery is one year. After one year of use, the battery can be discharged every two months, which has a good effect on prolonging the service life of the battery, but it is not necessary to recharge the new battery after each discharge. Finally, please note that the leaking battery should not be used again, otherwise the loss will outweigh the gain.
When charging the battery, use the original charger, and try not to use a charger that can charge multiple machines. Generally, mobile phones are equipped with travel chargers. If possible, you should use a seat charger. From the point of view that mobile phone manufacturers keep the function of charging directly through mobile phones, there should be certain technical guarantee. However, from the analysis of damaged components, the charging current is generally too large, which exceeds the load of the charging circuit in the mobile phone. The main reasons for this kind of failure are as follows: First, the power grid voltage in many cities in China is unstable, especially at night; Second, the battery quality is not good, or the battery power is used too hard. For mobile phone users, it is best to use fast charging as a temporary or emergency charging method at present, with seat charging as the main charging method. Because even if the latter method fails, it will not cause damage to the mobile phone itself.
If conductors such as jewelry, keys or beads come into contact with the exposed electrodes of the battery, these substances may make the current form a loop and become very hot, causing harm to people. In order to prevent accidental leakage, you should properly place the charged batteries and pay special attention to the batteries in your pockets and bags. After the battery of the mobile phone is removed, it should be put in a protective case. When the battery is not used for a long time, it should be placed in a protective sleeve and stored in a dry and dark place. Never put the cell phone battery at a high temperature (above 60℃), such as under a window with high temperature and direct sunlight. In addition, using lithium battery in low temperature environment may not guarantee the ideal standby and talk time of mobile phone.
Second, don't use the password lock card rashly.
When using GSM mobile phone, it should be noted that GSM mobile phone can not only lock the mobile phone, but also lock the card. If you forget your password after locking your mobile phone, you can solve it through various types of decryptors. However, if the PIN code is locked, the card will be locked. Because of the self-protection function of GSM-SIM card, after entering the wrong PIN code for three times, the mobile phone requires to enter the PUK code, and then enter the wrong PUK code for ten times. I'm so sorry. Your card is used up. At this time, Ericsson's mobile phone will generally display the black screen of SIM card, while Panasonic G500 will display SIM ERORR, indicating that SIM has been "burned out". Therefore, use the password lock card carefully.
Third, the correct way to deal with the water in the mobile phone
Once the mobile phone is flooded, take out the battery immediately, and never turn it on immediately to understand the situation of the mobile phone. After removing the battery, don't use a hair dryer to treat it. Send it to a professional for disassembly and water treatment immediately. If it falls into sewage or corrosive liquid, it should be cleaned by ultrasonic wave first, and then dried before the next maintenance treatment. If the mobile phone can still be used after being flooded, it should be sent to a professional to prevent the circuit board from being corroded and irreparable.
Fourth, keep the mobile phone dry and clean.
Note that rain, moisture and liquid contain minerals, which will corrode electronic circuit boards. Do not use or store the mobile phone in dusty or unclean places, which may damage its detachable parts. You can buy a leather case and put a protective coat on your mobile phone. Do not use chemicals, detergents or strong detergents to clean the mobile phone.
5. Don't store your mobile phone in a place that is too hot or too cold.
High temperature will shorten the life of electronic equipment, damage batteries, and deform or melt plastic parts. The mobile phone is stored in a cool place. When the temperature of the mobile phone rises, moisture will form in the mobile phone and damage the circuit board.
6. Don't use your mobile phone next to the program-controlled phone you are using.
Don't use GSM mobile phone next to the program-controlled telephone in use, because the interference between GSM mobile phone and program-controlled telephone is too great for both parties to hear clearly.
Seven, pay attention to save the phone and its components.
Don't drop, knock or shake your mobile phone. Rough handling will damage the internal circuit board. Pay attention to keep the mobile phone and its parts and accessories out of the reach of children to prevent accidental damage to the mobile phone.
Eight, don't turn on your mobile phone without permission.
Don't disassemble the mobile phone without permission. If the mobile phone or any of its components can't work normally, turn off the power immediately, and then take the mobile phone to a qualified maintenance agency nearby for repair. It is very easy for non-professionals to disassemble the mobile phone without permission.
