Repost @ Several ways to maintain your mobile phone

Maintenance of mobile phone batteries should start from the first charge. The first charge has a great impact on the subsequent service life of the battery. Generally, the first charge time is about 12 hours (if the battery has power, it should be used up first), but remember not to exceed 24 hours, otherwise the battery may be damaged. In the future, charging requires recharging every time it is used up, about 5-6 hours each time. The most important thing to note is not to recharge the battery when it is half used or to suddenly stop using the used battery for several months. The standard service life of the battery is one year. After one year of use, it can be discharged every two months, which has a good effect on extending the service life of the battery. However, new batteries do not need to be discharged and recharged every time. The correct way to deal with water in your mobile phone: Once your mobile phone is flooded, you should immediately remove the battery, and do not turn it on immediately to understand the condition of the mobile phone. After removing the battery, do not use a hair dryer to deal with it yourself. Send it to repair immediately and let professionals disassemble the battery and deal with water ingress. If it falls into sewage or corrosive liquid, it must be cleaned with ultrasonic waves and dried before proceeding to the next step of maintenance. If the mobile phone can still be used after being soaked in water, it should be sent to a professional to prevent the circuit board from being corroded and irreparable. GSM series (digital mobile phones): The confidentiality of GSM mobile phones is much higher than that of analog mobile phones, and the models are rich and colorful, with global roaming capabilities. They have become the first choice for the majority of users. When using GSM mobile phones, you should pay attention to the following points: In addition to the lock function, GSM mobile phones can also lock the card. If you forget the password after locking the phone, you can use the decryptor of various models to solve the problem. However, if the PIN code is locked, the card will be locked. Due to the self-protection function of the GSM-SIM card, after entering the wrong PIN code three times, the mobile phone requires you to enter the PUK code. If you enter the wrong PUK code ten more times, SORRY, your card is over. At this time, Ericsson 388 will display SIMCARDBLACKED, Panasonic G500 will display SIMERORR, etc. to indicate that the SIM has been "burned out". GSM mobile phones should not be used next to a program-controlled telephone that is in use, because the interference between the GSM mobile phone and the program-controlled telephone is so great that neither party can hear clearly. Care and maintenance: The following tips will help you comply with maintenance terms so that your phone will last for many years. Keep your phone dry. Rain, moisture and liquids contain minerals that can corrode electronic circuit boards. Using or storing your phone in dusty or unclean places may damage its removable parts. Do not store your phone in places that are too hot. High temperatures can shorten the life of electronic devices, destroy batteries, and cause some plastic parts to deform or melt. Do not store your phone in extremely cold places. When the temperature of the mobile phone rises, moisture will form inside the mobile phone and damage the circuit board. Don't try to take the phone apart. Handling the phone by non-professionals may damage the phone. Do not throw, knock or vibrate the phone. Treating your phone roughly can destroy the internal circuit boards. Do not use harsh chemicals, cleaning agents, or strong detergents to clean your phone. If your phone or any of its parts does not work properly, take it to the nearest qualified repair facility for repair. The battery should be removed when the phone is not used for a long time. You can often use a small amount of anhydrous alcohol to wipe the contacts of the mobile phone and battery electrodes to avoid poor contact between the battery and the mobile phone. To remove stains on the phone's appearance, wipe it with cotton dipped in a small amount of absolute alcohol. Use a stand-mounted charger whenever possible to help extend battery life. Once the mobile phone malfunctions, you should find professional maintenance personnel to repair it. Do not disassemble it yourself. Mobile phones are communication electronic products with high technical content and have very strict maintenance requirements. Therefore, repairs must be done at a warranty center or repair center authorized by the manufacturer to ensure the quality of the repaired components and use special testing equipment and tools to ensure the quality of repairs. If you use non-original components and non-special test equipment, tools, etc., your phone may be seriously damaged.
