Mobile phone battery is not durable? 14 tips to extend battery life
If the user wants to extend the effective service life of the battery, besides the quality of the charger, the correct charging method is also essential, because the poor quality charger or the wrong charging method will affect the service life and cycle life of the battery. Here are the skills that the author has compiled to extend the service life of the rechargeable battery of the mobile phone:
14 tips
1. Please use the charger of the original factory or a reputable brand, and use the special charger for lithium batteries, and follow the instructions, otherwise the battery will be damaged or even dangerous.
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 battery has no memory effect, but it has strong inertia. It should be fully activated to ensure the best performance in future use.
3. Before the battery leaves the factory, the manufacturers have activated it and pre-charged it, so all the batteries have surplus electricity. Some friends say that the battery is charged according to the adjustment period, 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 fully charged and discharged for 3~5 times.
4. Before charging, the lithium battery does not need special discharge, and improper discharge will damage the battery. Try to charge slowly when charging, and reduce the fast charging mode; 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.
Some automatic intelligent fast chargers only indicate that they are 90% full when the signal light changes. The charger will automatically change to charge the battery at a slow speed. It is best to use the battery after it is fully charged, otherwise it will shorten the use time.
6. Many users often leave their mobile phones on when charging. In fact, this will easily hurt the life of their mobile phones, because during the charging process, the circuit board of the mobile phones will heat up. At this time, if there is an external phone, it may produce instantaneous backflow current, which will damage the internal parts of the mobile phones.
7. The life of the battery depends on the number of repeated charge and discharge, so we should try to avoid charging the battery when there is surplus electricity, which will shorten the life of the battery. When the phone is turned off for more than 7 days, the battery of the phone should be fully discharged before use.
8. Mobile phone batteries all have self-discharge. When not in use, the Ni-MH battery will discharge about 1% of the remaining capacity every day, and the lithium battery will discharge 0.2%~0.3% every day. When charging the battery, try to use a special socket, and don’t share the socket with household appliances such as TV sets.
9. Although the mobile phone is within the network coverage area, it can no longer accept and make calls when the mobile phone is turned off and charged. At this time, you can use the mobile phone’s no-call transfer function to transfer the mobile phone to the fixed phone around you to prevent the loss of incoming calls. 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, like in dog days, don’t put the mobile phone in the car and expose it to the scorching sun; Or take it to an air-conditioned room and put it in a place where cold air blows directly. When charging, it is normal for the battery to be a little hot, but it cannot be subjected to the "suffering" of high temperature. In order to avoid this, it is best to charge at room temperature and don’t cover anything on the phone.
11. nickel cadmium (N iCd) battery must be fully charged before charging and fully charged after recharging.
12. If the mobile phone battery is left unused for too long, it is best to apply to the mobile phone maintenance department for a live treatment of the battery, or you can use a DC constant voltage device yourself to adjust the voltage to 5~6V and the current to 500~600mA to connect the battery in reverse. Note: release it at the touch, and repeat it for up to three times. After this treatment, use the original charger 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. Lithium-ion battery must use special charger, otherwise it may not reach saturation state, which will affect its performance. After charging, avoid placing it on the charger for more than 12 hours, and separate the battery from the mobile phone when it is not used for a long time.
The above 14-point mobile phone charging method has been proved by practice to effectively extend the life of mobile phone batteries, and friends who need it can try it, saving money and resources.
