■ If the mobile phone is idle for a long time, it needs special moisture-proof treatment. In southern areas such as South China, the weather is rainy and humid, and the moisture inside the mobile phone will cause damage to the parts.
■ Proper use of the mobile phone will generate a certain temperature inside the mobile phone, which will evaporate the water vapor accumulated at ordinary times.
■ Please avoid touching the antenna.
■ To avoid damaging the mobile phone and affecting the call quality, please do not install unqualified antennas or modified parts.
■ Handling your mobile phone according to the following suggestions will prolong its service life * Please keep the mobile phone and its components out of the reach of children.
* Keep the phone dry. Rain, moisture and liquid contain minerals, which will corrode electronic circuit boards.
* Using or storing the mobile phone in dusty or unclean places may damage its detachable parts.
* Don't store your mobile phone in an overheated place. High temperature will shorten the life of electronic equipment, damage batteries, and deform or melt some plastic parts.
* Don't store your mobile phone in a cold place. When the temperature of the mobile phone rises, moisture will form in the mobile phone and damage the circuit board.
* Don't try to disassemble the phone. Handling mobile phones by non-professionals will damage them.
* Don't throw, knock or shake your mobile phone. Rough handling of the mobile phone will damage the internal circuit board.
* Do not use chemicals, detergents or strong detergents to clean the mobile phone.
* If the mobile phone or any part of it doesn't work properly, please take it to the nearest qualified maintenance agency for repair.
Mobile phones focus on maintenance. As the saying goes, "prevention is better than cure". If something happens to your mobile phone every time, it may be too late. Therefore, if you know some daily maintenance methods of mobile phones, it will be very beneficial to your mobile phones.
Maintenance items
First of all, I suggest you use a mobile phone holster. The holster is equivalent to adding an extra coat to the mobile phone. On the one hand, it can reduce the wear of the mobile phone shell, on the other hand, it can reduce the damage of the mobile phone when it falls or meets water. Of course, this does not mean that the mobile phone will be fireproof after it is put on the leather case. When using and placing it, you still have to be careful to avoid damaging the phone.
Secondly, we should be careful about the use environment of mobile phones. The mobile phone has cracks or holes, which are easy to penetrate when it encounters moisture, leading to the erosion of the circuit board, so don't use the mobile phone in the rain or bathroom. At the same time, don't put the mobile phone in the air outlet of the air conditioner, because the water vapor condensed on the mobile phone will corrode the machine board invisibly. With the passage of time, the corrosion of circuit board by water vapor becomes more and more serious. At first, it may feel useless, but when the fault phenomenon appears, I'm afraid it's too late.
Third, pay attention to the way you carry it. Everyone carries a mobile phone in different ways, but some ways are easy to increase the chance of mobile phone damage. For example, it is customary to put the mobile phone in the pocket next to (behind) pants. If you are accidentally crushed while sitting, or if your mobile phone is squeezed off the ground while walking, it will cause damage to your mobile phone. In addition, like a light and small mobile phone, some people are used to putting it in their chest pockets, but they don't know that if they bend down carelessly, the mobile phone will fall to the ground.
Fourth, keep the mobile phone away from the magnet environment. The mobile phone speaker itself is magnetic, so don't let the mobile phone often touch places with a lot of iron powder, so as not to inhale too much iron powder from the sound hole of the mobile phone speaker and attach it to the speaker film, which will lead to the sound of the mobile phone receiver becoming smaller or even inaudible.

Mobile phones should be carried around every day and used frequently. In the process of use, it is inevitable to encounter unexpected situations such as water entry, falling and loss. If you know some basic first-aid knowledge of mobile phones, you can rescue them before sending them for repair, so as to minimize losses and keep your mobile phones.
1. If the mobile phone is flooded, it is common for the mobile phone to be flooded, such as getting wet by rain, spilling tea, falling into the water and so on. If something really happens unfortunately, please turn off the power immediately and take out the battery to avoid water droplets from corroding the machine board.
Water is the enemy of mobile phones, so it should be sent for repair as soon as possible. If it can't be repaired soon, you can use a hair dryer to dry the water inside the mobile phone to slow down the corrosion of the machine board. However, when using the air duct to blow dry, remember to adjust the temperature to a minimum to avoid the deformation of the rubber material of the fuselage due to overheating.
2. Rescue of automatic shutdown Many users have experienced the situation that the mobile phone will suddenly turn off automatically when it is in standby state with sufficient power. The reason may be: the protection circuit in lithium battery is too sensitive, and the power will be cut off when the current is large; The battery itself has aged; There is dirt on the metal plate at the contact position of the battery, which leads to poor contact of the power supply; The connection between the battery and the mobile phone is easy to loosen.
If you find the first two problems after inspection, you must go to a professional repair shop for repair. But if it is the latter two items, the problem is only caused by the dirty oxidation of the "battery metal sheet". As long as you clean it with a glue stick, the situation will get better. Putting paper or film between the battery and the mobile phone can also solve the problem of poor contact caused by loose battery.
If the mobile phone is lost, with the rapid growth of the number of mobile phones, the accidental loss of mobile phones is also increasing. If you don't handle it properly, you will not only lose your mobile phone, but also lose a lot of phone bills because of being stolen. After the mobile phone is lost, you should first call the police in time, and then go to the mobile phone business hall to apply for a replacement card as soon as possible. Individual users need to carry their ID cards, and unit users need to issue official letters of introduction from the unit, pay the card replacement fee of 150 yuan, and settle the phone bill of last month. If the card is replenished in time, there is no need to go through the procedures of stopping the card, starting it, etc., which saves the 80 yuan handling fee and minimizes the loss of mobile phone charges.
Shutdown procedures can be handled in the nearest telecom business hall. If you get lost, or lose your mobile phone at night or on holidays, you can apply for emergency stop service through 1860. When calling 1860 to stop the machine, you need to tell the waiter your ID number, mobile phone number and owner's name, and it can only be accepted after the service desk waiter verifies the relevant customer information. 24
In a few hours, your mobile phone will be shut down. In this way, an emergency stop is reported. When you go to the business hall to start or change cards, you need to go through the shutdown procedures again.
In order to prolong the service life of the battery, its charging time should not exceed the necessary charging period (5 to 7 hours); Only the original charger of the manufacturer can be used when purchasing the machine; Contacts of the battery should not contact with metal or greasy accessories; Do not immerse the battery in water, pay attention to moisture, and do not put it next to a low-temperature refrigerator or a high-temperature stove; Please use special facilities when handling batteries; If you need to replace the battery, please only use the battery type approved by the mobile phone; For the battery with memory effect, it should be charged every time after running out of electricity, otherwise the battery will have memory effect, which will greatly reduce the battery life; The normal life of the battery is calculated according to the charge and discharge cycle. Therefore, the battery life can be extended to the maximum extent when fully charged and discharged.
