How to maintain the lithium battery of mobile phone?

The ultimate purpose of mobile phone lithium battery maintenance is to extend the service life of the mobile phone battery, so that the mobile phone lithium battery can serve us for a longer time after a single charge. How to maintain the lithium battery of mobile phone?

Mobile phone lithium battery maintenance coup 1: Pay attention to the charging of the newly purchased mobile phone.

The newly bought mobile phone batteries are all lithium batteries, which are activated by the manufacturer, and each new mobile phone battery will have remaining power. Therefore, the first three to five charges of a newly purchased phone is an adjustment period. Note that each charge must be maintained for more than 14 hours in order to fully activate the activity of lithium ions and achieve the best use effect.

Mobile phone maintenance coup 2: The lithium battery does not need to be discharged, and it should be charged as slowly as possible.

Many netizens think that mobile phone batteries should be discharged and then charged, which is wrong. Lithium batteries do not need to be discharged. Lithium batteries do not have a discharge function now.

In addition, it is recommended to charge as slowly as possible when charging to reduce the consumption of the mobile phone battery. Note: No matter slow charging or fast charging, it can not exceed 24 hours, otherwise the battery will be burned out due to the huge electron flow generated by the long-term power supply.

Mobile phone repair coup 3: Don't turn off the power immediately after it is fully charged.

When the mobile phone battery is charging, if the mobile phone or charger shows that it is full, please do not turn off the power immediately, because the mobile phone battery is actually only 90% full at this time. The battery should be charged for a period of time and used after full charge, otherwise the use time will be shortened.

Mobile phone maintenance coup 4: Try not to turn it on while charging.

If the mobile phone is still turned on during the charging process, the mobile phone battery will discharge outward due to the use of the mobile phone, and supply power inward due to the battery charging, which may cause the circuit board of the mobile phone to heat up due to voltage imbalance. If there is an incoming call, an instantaneous backflow current will be generated, which will damage the internal parts of the mobile phone.

Mobile phone maintenance coup five: charge the battery when it is out of power.

Battery life depends on how many times your phone is charged. Generally, lithium batteries can be continuously charged and discharged about 500 times, after which the battery performance will be greatly weakened. Therefore, it is recommended that you try to charge your phone after it runs out of power or automatically shuts down.

Battery maintenance coup six: pay attention to protect the mobile phone battery.

To keep your phone battery in place, you must also take care to protect your phone battery. So, don't expose the battery to high temperature or severe cold, such as dog days, and don't put the phone in the sun. Or take it to an air-conditioned room and place it where the air conditioner is blowing directly. During the charging process, when the current product is reflowed, the battery is slightly hot, which is a normal phenomenon.

Battery maintenance coup 7: It needs to be activated if it is not used for a long time.

If the mobile phone battery is not used for a long time, you should go to a special mobile phone repair point to activate the battery. You can also use a DC constant voltage regulator to adjust the voltage to 5~6V, the current to 500~600mA, and reverse the battery. Note that it can be released with one key and z can be repeated up to 3 times. After this treatment, a "conditioning period" charge will be performed using the original charger. Battery maintenance coup 8: The longer the charging time, the better.

Pay attention to mobile phone charging, not to say that the longer the charging time, the better. If there is no protection circuit or non-original battery, it should be turned off immediately after fully charged, otherwise it will affect performance due to heat or overheating.

Attachment: Calculation method of battery theoretical charging time:

Divide the battery capacity by the output current of the charger. Take a battery with a capacity of 800MAH as an example. If the output current of the charger is 500MA, the charging time is equal to 800MAH/500MA=1.6 hours. Of course, this is only a theoretical calculation of the time to fully charge. When the charger shows that charging is complete, it is best to charge the battery for about half an hour. Lithium-ion batteries must be equipped with a dedicated charger, otherwise they may not reach saturation and affect performance.

Battery maintenance tip 9: Small details can also extend battery life.

After the mobile phone is used for a long time, the contacts will be oxidized, resulting in the automatic shutdown of the mobile phone or the automatic disconnection of the mobile phone during the call. At this time, you can wipe with a small cotton swab or a paper towel wrapped in a little alcohol. Do not scratch with hard objects, it will aggravate poor contact. No alcohol can be substituted with high alcohol alcohol. Dry immediately after wiping to avoid battery short circuit due to alcohol spillage. After 3-5 full charge-discharge cycles, the chemistry in the new battery will be fully "activated" for optimal use.

Battery maintenance coup 10: Use the original battery of the mobile phone manufacturer.

Remind netizens, please try to use the original mobile phone batteries and chargers of mobile phone manufacturers, or use regular products, and do not buy mobile phone batteries and chargers from roadside stalls or unreliable places.

Attachment: Appearance characteristics of genuine mobile phone batteries, which are convenient for everyone to identify when purchasing:

Genuine mobile phone batteries generally have the following appearance features: The battery label adopts secondary printing technology. Under a certain light, the color of the barcode part is obviously darker than other parts, and the hand feels slightly convex than other parts. Many original batteries have this feature. The white part of the surface of the genuine battery label is lightly scratched by metal objects, and there are traces of pencil scratches. The battery case is made of special material, which is very strong and not easily damaged. The battery compartment is generally not easy to open. The appearance of the battery is neat, there is no unnecessary burr, the outer surface has a certain roughness, and the hand feels comfortable.
