Why is the phone charging so slow, and why is the phone charging particularly slow

Do you want to consult about the slow charging of Huawei mobile phones?

It is recommended that you use the standard charger for charging. When charging, the charger, data cable, and mobile phone charging interface are not in good contact, which may lead to slow charging and failure to charge, please plug and unplug the charger several times. Please check that the connectors and jacks are clean, and if you find dust, it is recommended to wipe them with alcohol or clean them with a brush.

If it is an alcohol wipe, wait for the alcohol to dry before recharging for confirmation. It is recommended not to use your phone while charging, especially to close power-hungry apps such as ** and games. Because if the mobile phone is charging, playing games and watching ** when surfing the Internet, part of the input current of the charger needs to offset the power consumed by the mobile phone hardware such as the screen when it is in use, resulting in a decrease in the current used to charge the battery, and the charging speed will be slower.

If the phone prompts slow charging, please use the standard charger and data cable, and make sure that the connection between the charger and the data cable is tight.

If your phone does not prompt slow charging, but you still feel that the charging speed is slow, please check the following:

1) Avoid using your phone while charging.

2) End the enddesk to run the program (the last application button in the bottom left corner - end).

3) 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.

If your Samsung phone is charging slowly, it is recommended:

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.

Samsung Service Center Address Information Customer Service**, you can inquire through the following methods: Please log in to the service center page of Samsung's official website - select the product you want to inquire about and the province or city where you are located to search.

There are two possible reasons why the mobile phone is charging very slowly, the first may be that the quality of your charger is not good, the charging current is very small, and the other may be that the charging interface is not good and the contact is poor. You can try it with a different charging head and a better charging cable.

It is possible that the battery of the mobile phone is aging.

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.

The biggest possibility is that the mobile phone does not support fast charging at all, or that the charging cable of the charging head you use for water is not a fast charging charging cable.

If you are using an OPPO or OnePlus mobile phone, the slow charging of the mobile phone is affected by many factors, such as charger conditions, environmental factors, charging habits, etc., it is recommended that you troubleshoot as follows:

1. Please make sure to use the original charging head and charging cable, and use a non-original charger for charging, the software will identify it as a non-standard charger, and the charging current will be limited to cause slow charging.

2. It is recommended that you try to avoid using the mobile phone while charging, if the mobile phone is seriously heated, it is recommended that you restart the mobile phone and wait for the temperature to decrease before charging.

3. The ambient temperature is too high or too low, which will affect the charging speed of the lithium battery, it is recommended that you charge the mobile phone in a suitable environment (15 -35), one key to clear the cheats and understand the background program.

4. It is recommended that you try to replace the charging head and data cable to check whether it is caused by damage to the adapter or data cable.

5. Restart your phone and try to plug the cable again.

6. It is recommended that you upgrade your mobile phone system to the latest version.

7. Some A series mobile phones are equipped with night charging protection function, this function will slow down the charging speed in the middle of the night, and it is expected to be full when you get up after 6 o'clock in the morning. If you don't need this feature, you can turn it off via the following path: Settings > Battery > More > Night Charging Molds Loose Hood > Off .

If the above methods do not solve your problem, you can go to the nearest OPPO official service center to deal with it, and professional engineers will test and deal with it.

Smartphones have the problem of fast power consumption, after all, today's mobile phones have large screens and many functions, and it is impossible for people to use them frequently and consume little power. When helping to charge the mobile phone, many people will find that the charging effect of their mobile phone is getting worse and worse, and it takes more than an hour to complete the charging of the mobile phone, but now it takes more than two hours to complete the charging. Due to the fact that the phone is charging too slowly, it also causes trouble for me to use the phone.

So, how to solve the problem of slow charging of mobile phones?

Slow phone charging solution.

1.It is recommended to activate the battery by the way while charging it in the future, so that there is no memory when the battery is charged.

2.Charge with an AC socket, charge the spine to 100% and turn it off, then charge it in shutdown mode until the green light is on.

3.Enter the recovery mode, select advancsd advanced mode, select wipe battery, and clear battery traces.

4.Charge to 100% on boot so that your battery has no memory and can be charged much faster later.

A phone with a large battery capacity takes longer to charge.

To discuss the speed that affects the charging of mobile phones, we must first understand how to calculate the charging time, which can be calculated by a simple formula: charging time = coefficient (generally greater than 1) battery capacity (mAh) charging current (mA). That is, when the charging current is constant, the larger the battery capacity, the longer the charging time; When the battery capacity is constant, the larger the charging and bleeding current, the longer the charging time.

It can be seen that in order to meet the needs of people to use mobile phones for a long time, when the charging current remains the same, manufacturers increase the capacity of mobile phones, and people have to charge their devices for a longer time.

In addition, in practice, the current is determined according to the load (i.e. the mobile phone) that is connected later. As long as the phone needs as much current as it can, the charger can provide as much current as it can. If the phone needs more current than the charger can provide, the charger will always output this maximum current.

Therefore, when the battery capacity is the same, the more current the phone itself can carry, the faster its charging time will be.

The charging specifications of the power adapter affect the charging speed.

Nowadays, most brand mobile phones are equipped with standard chargers with standard 5V, but manufacturers generally equip different output currents according to the battery capacity. Someone once compared the difference between a 2A charger and a 2-lane charger if the voltage is the same—every time the current is doubled, the amount of charge doubled in the same amount of time. Therefore, when charging the iPad with the charger of the iPhone with a maximum output current of only 1A and charging the iPad with the original charger of 2A, the charging time of the former is twice that of the latter under theoretical conditions.

Therefore, when charging the mobile phone, in order to ensure that the charging speed of the mobile phone is fast enough, you should try to choose the original charger or other brands of chargers with an output current not lower than the original standard.
