Hello everyone, Lin Fei to answer the above questions, the mobile phone battery can not be charged, many people do not know, now let's take a look!

What are the reasons why the mobile phone battery cannot be recharged? Mobile phones have brought great convenience to our modern life. Today, the number of mobile phone users is growing exponentially. I believe that many mobile phones will encounter some failures when they are in normal use. For example, what if the mobile phone battery cannot be charged?

Why can't the cell phone battery be recharged?

1. If the use time is too long and the charge and discharge cycle is reached, the new battery should be replaced.

two。 If you buy a battery made of a low-quality battery, the internal short circuit is easy to show that it is fully charged, but there is no charge, or the damage cannot be admitted or charged.

3. The question of the mode of charging. Do you think the directly charged contact piece is in correct contact with the battery? Changing the position (there are several contacts on the battery, try to match them) or pressing (some of them mobile) the changeover switch on the charger may be sufficient.

What if the cell phone battery doesn't charge?

1. Mobile phone batteries are now lithium-ion batteries. Lithium-ion batteries are completely different from nickel batteries. You can charge lithium-ion batteries at any time as long as it is convenient for you, unlike Ni-MH batteries. In order to maximize its performance, it must be fully discharged before it can be charged and fully charged.

two。 The life of lithium battery is related to the number of charging cycles, but not directly related to the number of charging times. A charging cycle refers to all the charges of the battery from full to depleted, and then from depleted to full. This is not the same as recharging. After each charging cycle, the power will be reduced a little. However, the reduction is very small. After many cycles of charging, the high-quality battery will still retain 80% of its original charge. This is why many lithium power products are still in use two or three years later. Of course, lithium batteries need to be replaced at the end of their life.

The life of lithium is usually 300-500 charging cycles. It can also be understood that the life of the lithium battery is related to the total charging capacity of the battery and has nothing to do with the number of charges. The effects of deep charging and shallow charging on the life of lithium battery are similar. In fact, shallow discharge and shallow charging are more beneficial to lithium batteries. Deep discharge and charging are required only if the power supply module of the product is calibrated for lithium batteries.

3. Lithium battery-powered products do not have to stick to the process. Everything is convenient first, can be recharged at any time, do not have to worry about affecting life.

4. What is really bad about lithium batteries is to use lithium batteries above the required operating temperature, that is, more than 35%. If you have to charge the device at this temperature, the damage to the battery will be even greater. If the lithium battery is used in a low temperature environment, that is, below 4, it will also be found that the service life of the battery is reduced, and the original lithium battery of some mobile phones cannot even be recharged at low temperature. But don't worry too much, this is only a temporary situation, which is different from the use in high temperature environment. Once the temperature rises and the molecules in the battery are heated, they immediately return to their previous charge.

5. If you want to maximize the efficiency of a lithium-ion battery, you need to use it frequently to keep the electrons in the lithium-ion battery flowing all the time. If you do not use lithium batteries often, please remember to complete the charging cycle of lithium batteries once a month and do a charge calibration, that is, a deep discharge and deep charge.

6. If your mobile phone is equipped with Kingsoft battery, the doctor will save you a lot of time and energy to maintain your mobile phone battery. Dr. Kingsoft battery has achieved the effect of prolonging battery life by optimizing the charging process.

At the end of this article, I hope it will be helpful to you.
