How to extend the life of mobile phone batteries

We know that the battery is the source of mobile phone power, which is the power of the mobile phone. There is no battery power supply. The mobile phone is a piece of scrap iron. A high-capacity and high-performance battery can not only give the mobile phone a long-term battery life, but also protect the mobile phone. The circuit allows the mobile phone to work efficiently for a long time. Otherwise, it may cause unexpected damage to the mobile phone. For our players, the performance of the battery is already determined when it is shipped from the factory. The size of the battery and the performance of the battery are determined by the battery itself. In this respect, we cannot artificially change it. This does not mean that we can't do anything about it after we get the battery. Lithium-ion rechargeable batteries are used in mobile phones. The use of the internal storage battery will require recharging before recharging. You should not underestimate this link. A good charger and proper charging method can maintain the standby time of the battery for a long time and extend the service life of the battery. Further, it can also protect the mobile phone. With regard to how to charge, there are often players who ask in the forum. After a period of actual use and reference, I summarize the following points:

1. General Lithium battery before leaving factory, the manufacturer carries on the activation treatment, and carries on the precharge, therefore the battery all has surplus electricity, the newly-purchased mobile phone battery is the lithium ion, then the first 3 to 5 charges are called the adjustment period, should charge over 14 hours, guaranteed The activity of lithium ion is fully activated. Lithium-ion batteries have no memory effect, but they have a strong tendency to be fully activated before they can be used to achieve optimal performance. Regarding the first charge, I also consulted with Samsung's technical staff. The answer given to me was that Samsung’s original battery had already been fully activated before leaving the factory, eliminating the need for long-term charging. Activation of lithium ion activity, the first charge as long as the residual power in the battery is used up. I think Samsung's technical staff should be convinced.

2. Some automated smart chargers actually only indicate 90% full when the indicator lights change. The charger will automatically change to charge the battery with slow charging. Do not immediately cut off the charger's power, it is best to give the battery a charge time, the battery is full before use, otherwise it will shorten the use of time.

3. Before charging, the lithium battery does not need to be discharged or discharged. The current production of lithium battery chargers does not have a discharge function. If it is possible to adjust the charging speed, it is recommended that you charge as slowly as possible when charging, reducing fast charging. Way; no matter whether slow charge or fast charge time should not exceed 24 hours. Otherwise, the battery is likely to cause a huge flow of electrons and burn out the battery cells due to prolonged power supply.

4. Many users also leave the mobile phone on charge. During the charging process, the battery discharges outward due to the use of the mobile phone, and inward power supply due to the charging of the battery. This may cause the voltage of the mobile phone circuit board to be disordered. Fever, if there is an incoming call, it will produce instant return current, causing damage to the internal parts of the phone.

5. The battery life depends on the number of repeated charge and discharge, lithium battery can be about 500 times continuous charge and discharge, after the performance of the battery will be greatly weakened, should try to avoid the battery after the release of all the remaining charge, otherwise with the increase in the number of charging The battery performance will gradually weaken and the standby time of the battery will not be reduced.

6. Do not expose the battery to high temperatures or severe cold. Like the dog days, you should not put your phone under the sun and withstand the sun exposure; or get it in an air-conditioned room and place it in a cool place. When charging, the current product returns, and it is normal for the battery to have a little heat.

7. If the mobile phone battery is left unused for a long time, it is best to apply for activation of the battery to the mobile phone repair department. You can also use a DC voltage regulator to adjust the voltage to 5~6V and the current 500~600mA to connect the battery reversely. . Note that one touch is released and it can be repeated up to three times. After such processing, the original charger is used for “adjustment period” charging.

8. The longer the charging is, the better the time is. The charging should be stopped after the battery without the protection circuit is full. Otherwise, the performance may be affected by heat or overheating. The method of calculating the theoretical charging time of the battery is as follows: The battery power divided by the output current of the charger can be, for example: a battery with 800MAH battery as an example, the output current of the charger is 500MA, then the charging time is equal to 800MAH/500MA. = 1.6 hours, of course, this is only a theoretically full-charged time calculation. When the charger shows that the charging is complete, it is best to give the battery about half an hour of recharge time. Lithium-ion batteries must use special chargers, otherwise they may not reach saturation and affect their performance.
