Can the newly bought mobile phone be charged with a universal charger?

Not recommended, the new battery must be well maintained. Generally, it needs to be recharged when there is no electricity. The life of mobile phone battery is determined by the number of times of charging. Here are some ways to maintain mobile phone batteries, which I hope will be useful to you: 1. Before the battery leaves the factory, the manufacturer has activated and precharged it, so the battery has 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. Anyone who wants to buy a mobile phone must come in and have a look! .
