Why is the charging of the data cable so slow, it used to be so slow now

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 the charging head supports up to 65W power, and the charging cable supports up to 20W power, then the charging speed will still be slow, and we can only use the matching charger to charge quickly.

Data expansion: Some computer chargers can charge mobile phones, for example, Huawei computer chargers can charge Huawei mobile phones, because Huawei computer chargers support 18W fast charging, and it happens that Huawei mobile phones also support 18W fast charging, so it is adaptable. If your phone has an original charger, it is recommended that you use the original charger.

The mobile phone charger can also charge the computer, for example, the Xiaomi mobile phone charger, the charging power has reached up to 65W, which can meet the computer charging, but the charger is seriously heated, so it is not recommended that users use the mobile phone charger to charge the computer.

However, some mobile phone chargers cannot charge the computer, because the charging bureau is different from the specifications of electrical appliances, the specifications of the mobile phone charger are generally Type-C interface, and the computer charger is AC interface, so it is not suitable.

The Type-C charger has a variety of benefits, such as it supports a minimum of 5W charging power, and the charging speed is still guaranteed. The data cable with this interface specification is also very fast to transfer files, and the transfer is more secure, and there will be no file loss.

The phone doesn't flash charge, what should I do, let's study it together:

1. If possible, it is recommended to replace a set of OPPO (Super) flash charger to see if the adapter or data cable is broken.

2. It is recommended that you stop using high-power software when charging, especially games, cameras, etc., and then check the charging situation, if the phone is seriously heated, it is recommended that you restart the phone and wait for the temperature to drop 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 after cleaning the background program with one click in a suitable environment of 15 35.

4. It is recommended that you restart your phone and then plug in the data cable again to try to charge.

If the above methods are of limited help to you, please bring the purchase invoice, warranty card, mobile phone and charger to the nearest OPPO official service center for testing and processing by professional engineers.

<> the charging of the data cable is slow because different data cables have different power sizes, or it may be that the power of the charger is low, if the charging power supported by the mobile phone is larger, and the data cable and charging head provided are smaller, there will be slow charging, and the original charger should be selected when charging the mobile phone.

The slow charging of the mobile phone data cable may be due to the mismatch between the power of the mobile phone and the data cable, resulting in a small amount of current.

If the charging power of the data cable is lower than the charging power supported by the stove mobile phone, it will cause the charging speed of the mobile phone to slow down.

In addition, the non-original charger will also affect the charging speed of the mobile phone.

Operating environmentMake model: Redmi Note 8 Pro

System Version:

Your problem seems to be on the data line, which has nothing to do with the transmission rate, 15 pieces of a piece is very rare, it is best to go to the store to buy the original.

1. 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.

4. The lithium battery will start the lithium battery protection when the battery is very low, and the mobile phone cannot be turned on at this time, and there is no response at the initial stage of charging, and the charging time will become longer. The charged phone needs to wait a long time for the battery to wake up and turn off the protection. So try not to wait until the battery runs out to remember charging.

5. Many low-cost data cables look very thick, but the core inside them is very thin, or they are replaced by pure copper to aluminum wires. In addition, there may be hidden dangers in the contact material and welding of inferior data cable connectors, the above problems will lead to an increase in resistance, the standard data line resistance should be ohms, and the inferior wire may reach 3 6 ohms, and the charging efficiency will naturally drop by 6 to 12 times.

It's best to buy the original charger, if the original charger is too expensive, it is recommended to buy a vivo charger, and it is cheaper to buy it on Pinduoduo, but I use it no different from the original.

Directly hold the copper wire and link the home to 220 volts.

Buy charging cables and chargers, not casually, just buy the right ones.

Buy a more expensive fast charging cable, or an original charging cable, it's up to you.

Replace it and buy a fast-charging cable.
