Sometimes the charging is suddenly slow, and even after two hours, it takes 40 to charge, and I char

Your phone is charging slowly, which can be due to the following reasons:

1.Failure to use the standard charger and data cable: Products that support super fast charging must use the standard super fast charger and the standard data cable to perform super fast charging, and the use of other models of chargers and data cables is normal charging or cannot be charged.

If you are using a non-standard charger cable, please replace it and try again.

2.The charger or data cable is not plugged in properly or the interface is not clean: please plug and unplug the charger several times, check whether the connector and jack are clean, if you find dust, it is recommended to wipe it with alcohol or clean it with a brush.

If it is an alcohol wipe, wait for the alcohol to dry before recharging for confirmation.

3.Caused by high ambient temperature and heating of the mobile phone: It is recommended to wait for the temperature of the mobile phone to decrease before charging, and it is recommended to close the applications running in the background when charging, so as to avoid the temperature rise when the mobile phone consumes high power.

4.Charging while using will cause the temperature to rise significantly. Huawei phones are designed with overheat protection, and when the device temperature is high, the charging current will gradually decrease, and the charging speed will slow down until it is fully charged, so please feel free to use it.

If it is not caused by the above reasons, it is recommended to back up the data in the mobile phone in advance and bring the warranty certificate to the nearby customer service center for repair. The following describes how to query the address information of the Huawei Customer Service Center:

2) At the bottom of the Huawei page, click "After-sales outlets" to query the address.

If your Samsung phone also has slow charging when it is on standby, it is recommended to try it:

1.Use the original charger to turn off the charging and check whether the phone is slow to charge when it is turned off.

2.If your phone is only charging slowly when it is turned on, please do you:

1) End the end-run program (Recent Applications button in the bottom left corner - End) 2) Uninstall the third-party battery management software from your phone.

1) Check if there is a version update on your phone and upgrade to the latest version.

2) Please back up the data in your phone and restore your phone to factory settings.

3) If the above methods are invalid, please bring the purchase invoice, warranty card and machine to the Samsung service center, and a professional after-sales engineer will help you deal with it.

Replace the battery with a universal charger to see if the battery is broken or if there is a problem with the charger.

The chip that should have been the phone's charging port is broken. Try a new cable. That's how I am, now a month or so to change the cable.

Can you try to format your phone, my phone has been like this for a while, just format it.

The current intensity does not match the charger requirements! Do you have any new high-power appliances at home?

Isn't there how much A is on the charger You see how much you have Mine is The charger current is small.

The phone charger is broken, or the plug core inside the phone is broken.

The power adapter is broken, the data cable is broken,,, the battery is broken.

The battery contacts are not good, and there is a problem with the data cable.

Isn't it that when you look at it, they were all 80, and it was very slow at that time.

The charger is broken, the battery is broken, or the phone is broken, or... There is a problem with the current.

Turn off the machine and flush for a while.

Just change the charger plug.

The inside of the charger is broken or in poor contact.

Hello, charging with the original fast charger suddenly becomes very slow may be a problem with the poor contact between the phone and the charger and the temperature during charging. Mobile phone system problems and other reasons:

1. Check the charging interface, it may be dusty.

Since we are usually used to putting our mobile phones in our trouser pockets, the charging port located at the bottom of the mobile phone is easy to enter the dust, and the interface is easy to contact the power cord plug poorly. Therefore, when the mobile phone cannot be charged, it is necessary to check whether the interface at the bottom of the mobile phone is blocked by foreign objects as soon as possible.

2. Check the data cable and try another one.

If there is no problem with the power interface of the mobile phone, it is likely that the charging data cable is a problem! You can borrow someone else's mobile phone data cable to charge it. If the charging speed is normal after changing the cable, it means that there is a problem with the cable, and the speed should buy a new data cable.

3. If there is a system problem, try restarting.

The phone is charging slowly and does not respond, sometimes it may be due to the system, resulting in the phone not charging. Rebooting can solve 70% of mobile phone problems, you can remember this "truth", you may wish to restart the phone if there is a problem.

4. Pay attention to the temperature, it is difficult to charge if it is too high or too low.

Due to the physical characteristics of the battery, it is particularly sensitive to temperature, too high will cause problems, too low will cause it to not charge. If the temperature is too low in the area you are in, please put your phone in the quilt or air-conditioned room to let the phone be at a normal temperature before charging it.

5. If the above methods do not work, then it may be that the hardware of the mobile phone is broken, so it cannot be charged. At this time, the mobile phone may have a hardware failure, please send the mobile phone to the mobile phone authorized service for testing, and let the after-sales staff of the mobile phone help you solve it.

Virtual power is usually a lack of battery life caused by incorrect operation, users often operate the mobile phone in the charging state, use non-original data cables for charging, charge when the power is empty for a long time, and often use the power bank to charge.

According to the above reasons, the user should eliminate them one by one and solve them one by one, so as not to cause fatal damage to the battery again.

Don't wait for the charge to run out to charge, the charging goes through first:

Constant current stage, at this time, the actual voltage of the battery is lower than the charging voltage (mostly, the battery voltage is increased during the constant current charging process, when it is increased to about 85% of the battery power is full), enter, constant voltage mode, the charging current is gradually reduced, the charging is about to be completed, and then enter, trickle charging mode, charging with pulse current, prolonging the battery life When the charger is charging, it is normal for the charger to heat up, but it is not normal to be hot.

3.Clean up the background running while charging.

Hello and welcome to the Samsung Digital Services platform.

I've also encountered this kind of problem It's the charging data cable is broken, and it's okay to replace it with a new one, and a reminder, don't go to the street to sell cheap ones, the kind that is most likely to break, buy a better one, and finally the original one, I hope to adopt it, thank you.

If your phone is charging slowly, it is recommended that you:

1.Check that you are using the original charger.

2.It is recommended not to use the phone while charging, as it may prolong the time for the battery to be fully charged.

3.Check whether there is also a slow charging situation when the power is turned off and charging. If it only appears on boot charging, it is recommended to end the end-end application before charging.

4.If your phone does not have a built-in battery, it is recommended to remove the battery and put it back in or replace it with another original battery.

If the problem persists, it is recommended that you bring the purchase invoice, warranty card, mobile phone, and charger to the local Samsung service center, and a professional engineer will help you test it.

Operating the device for a long time while the phone is charging may cause the phone to heat up and the charging time to prolong. Therefore, it is recommended that you should keep the device charging normally.

Let's see if it's the original charger first! Then turn it off from the start.

It is recommended to replace the data cable and restart the phone, if there is still this phenomenon, it is estimated that the battery is aging, which can be detected.
