Coolpad has an unusual sound that can t be charged

1. The mobile phone can't be charged, of course we have to find out what is the problem, and only when we find the problem can we prescribe the right medicine. Below I will go step by step to check what the problem is from simple to difficult. 2. First of all, connect the mobile phone with the charger and plug it into the plug board to see if it can be charged.

If it can't be charged, then the current possible problems are: the charger is broken, the connection line is broken, the mobile phone interface is broken, the battery is broken, and the system problem is then eliminated 3, change a connection cable or change the charging plug, and then charge to see if it can be charged in. Pay attention to the current and voltage of the original charging plug of your mobile phone when changing the charging plug to prevent harm to the mobile phone.

If you can't rush, then the possible problem is: mobile phone interface problems, battery problems, system problems 4, remove the battery, use the universal charge to flush, if the rush is the problem of the mobile phone charging interface, if not, then continue to troubleshoot There may be problems: battery, system 5, change the battery to see if you can rush in, if you change the battery can be charged, it is likely that the battery is scrapped.

Just change the battery. If it still can't be charged, then it can only be a problem with the system. Note that the battery is best the original or buy the best business battery, everyone must pay attention!

That's the case with my phone right now, coolpad.

Cause: Plugging and unplugging data cables and poor contact with power adapters.

Caused by abnormal charging data cable and power adapter accessories.

It is not ruled out that it is caused by battery failure.

The phone system is damaged.

Solution: It is recommended to replug the data cable and power adapter to rule out the cause of poor contact.

It is recommended to try to replace the charging data cable and power adapter if possible, if it can be improved after replacement, it can be inferred that the accessories are abnormal.

If there are other batteries (if the mobile phone supports self-battery replacement), it is recommended to try to replace them, and the battery failure cannot be ruled out.

If the problem still cannot be effectively solved, it is recommended to take the time to go to a nearby authorized maintenance station for specific testing and treatment for your normal use in the future.

Reasons why the battery won't charge:

1. The mobile phone battery cannot be charged, and it may be that the battery has entered a dormant state.

This is mostly caused by the user running out of power and the phone automatically shuts down.

The solution to this situation is to remove the battery, wait 5 minutes, and then reinstall the battery. Use a data cable to connect your phone to your computer, and after 30 minutes, turn it back on.

2. In the case of sudden mobile phone battery not charging, you also need to check whether you use a regular original charger.

If you are using a different charger, you need to check if there is a problem with the charger or if the charger port is damaged. Switching to a new charger can solve this situation.

3. If the mobile phone can be connected to the charger for charging, but it is not always fully charged, you need to check whether there is a problem with the mobile phone system.

Sometimes, you install battery management software that protects the battery on your phone, and when there is a problem with these software, the battery will not be fully charged. You can use a universal charger to charge the battery of your mobile phone and check whether the battery is damaged. If the battery can be fully charged with universal charging, then you should repair the phone system or flash it.

4. In addition to the above situations, the loose charging interface of the mobile phone and the short circuit of the internal charging circuit of the mobile phone will also cause the mobile phone battery to not be charged.

In this case, you need to send the mobile phone to a professional after-sales repair network for maintenance.

Tips for caring for your battery:

1. The battery does not need to be charged after all the power is used up.

Today's smartphone batteries are all lithium batteries, and for lithium batteries, it has no effect at all if the battery is fully charged for a long time, and it is even harmful. Because there is no so-called "caching effect" in lithium batteries, only early nickel batteries have this feature.

The lifespan of a smartphone battery is generally only related to man-made damage or natural life. Basically, the life of the battery is fixed, 600-1000 times of charge and discharge!

2. When the power supply is connected, the battery can be unplugged or not.

Unplugging or not unplugging depends on the actual use case: not unplugging the battery while connecting to the DC power supply does not harm the battery, because the battery will no longer receive any power injection after it is fully charged, and all the power will be directly directed to the smartphone's power supply** system. But when the smartphone is running at high speed and the inside is overheating, it is better to remove the battery, otherwise it is harmful.

It is not recommended to use it while charging, especially in the summer when the weather is hot!

3. How to properly charge your smartphone.

Try to avoid waiting for the battery to run out before charging, as this can put a lot of stress on the battery and cause damage. It is more feasible to charge when there is about 20-30% of the battery remaining.

In fact, there is a limit to the number of times a smartphone's lithium battery can be "recharged", and recharging it all will only greatly shorten the battery life. At the same time, the battery should be charged in a relatively dry place, and it is also necessary to pay attention to the heat problem, which is the enemy of the battery.

If you can be full, the mobile charger you are talking about is a direct charger (that is, a wire charge, directly plugged into the tail charger) can not be filled, that is the machine has a problem, and the warranty will be made if it is not warranted. Secondly, there is the battery problem
