What should we do if the cell phone battery won't charge?

What are the reasons cell phone batteries don't charge? Cell phones have brought great convenience to our modern life. Nowadays, the number of mobile phone users is increasing exponentially. I believe that many mobile phones will encounter some problems when they are used normally. For example, what if the cell phone battery doesn't charge?

Why can't a cell phone battery charge

1. If the battery is used for too long and reaches the charging and discharging cycle, the battery should be replaced.

2. After purchasing the battery made of inferior batteries, the internal short circuit is easy to show that the battery is full when charging, but there is no electricity; Or the damage cannot be determined and prosecuted.

3. If there is a problem with the charging method, if you see whether the contact piece directly charged contacts the battery correctly, change the position (there are several contacts on the battery, try to match), or press (or move) the transfer switch on the charger.

What should I do when my cell phone battery dies?

1. Lithium-ion batteries are now used in mobile phone batteries. Lithium-ion batteries are completely different from nickel batteries. Lithium-ion batteries can be recharged whenever you like, which is completely different from nickel-metal hydride batteries. In order to maximize its performance, it must be completely discharged before charging, and it must be fully charged.

2. Lithium-ion battery life is related to the completion of the charging cycle, and has no direct relationship with the number of charging. The charging cycle is when all of the battery's charges are used from full to empty, and then charged from empty to full. It's not the same as a charge. After each charging cycle, the charge decreases a little. However, the reduction was small. Good batteries retain 80 per cent of their original power after multiple cycles of recharging. That's why a lot of lithium-powered products are still working after two or three years. Of course, lithium-ion batteries need to be replaced at the end of their lives.

Lithium-ion batteries generally have a life span of 300-500 charging cycles. It can also be understood that the life of lithium battery is related to the total charging capacity of the battery, and has nothing to do with the number of charging. The effect of deep discharge and shallow discharge on lithium-ion battery life is not significant. In fact, shallow discharge and shallow charge are better for lithium batteries. The power module of the product requires deep discharge charging only when it is calibrated for the lithium battery.

3. Lithium-ion battery powered products do not need to adhere to this process. Everything is convenient first, charging at any time, do not worry about affecting the service life.

4. The real disadvantage to lithium batteries is that they are used in an environment higher than the specified operating temperature, that is, above 35C. If the device is charged at such a temperature, the damage to the battery will be greater. If the lithium-ion battery is used in a low temperature environment, that is, below 4C, it will also be found that the service time of the battery is shortened. The original lithium-ion battery of some mobile phones can not even be charged in a low temperature environment. But don't worry too much, this is only a temporary situation, and the use of high temperature environment is not the same. Once the temperature rises, the molecules in the cell are heated, and the charge is immediately restored to its previous level.

5. To get the most out of a lithium-ion battery, it needs to be used frequently to keep the electrons in the battery flowing. If you do not use the lithium battery often, please remember to complete a charge cycle for the lithium battery every month, and do a charge calibration, namely deep discharge and deep charge.

6. If you install Kingsoft battery on your mobile phone, the doctor will save you a lot of time and energy on the maintenance of mobile phone battery. Kingsoft Battery Doctor optimizes the charging process to extend the battery life.
