How to fix SuperCharge does not work on Huawei P30 | Slow charging problems

The huge 3.650 mAh battery pack of your Huawei P30 is an improvement over the older models, so a quick charge function is required to complete it. The fact is that fast charging can sometimes slow down on Huawei P30. This can occur for a variety of reasons. You will need to perform a series of steps to resolve the problem. This troubleshooting article should help you do it.

How to fix SuperCharge does not work on Huawei P30 | Slow charging problems

If your Huawei P30 is charging slowly or SuperCharge is not working, follow the steps below to resolve the issue.

1) Confirm that the charger works

If you have noticed that your Huawei P30 has been charging slowly lately, the first thing you can do is check the charging accessories. By default, your device should load quickly, so if you don't quickly recharge one of them, the cable or adapter won't work.

They can be too many apps running in the background, hardware problems or a defective charging cable or adapter. In this situation, first, try to determine if it has something to do with the charging cable and the adapter. Ideally, you should use the accessories provided in the package.

If you are using a third-party cable and adapter, try charging your phone with genuine Huawei P30 accessories first. Or ask them to borrow from a family member or friend.

Also keep in mind if you are using a genuine Huawei charging cable and adapter, its specifications may be lower and will not produce the Huawei P30 fast charge requirements.

There are four types of chargers for Huawei devices. Try checking each one and see if you are using what is not compatible with Huawei P30 fast charge. Follow this link for more information.

2) Check for hardware damage

Historically, Huawei devices have good results. In many cases where they are not recharged, the main cause is a hardware malfunction or failure. In order not to waste time-solving the wrong problem, you must first know if there is a possibility that it is the fault of faulty hardware.

If you dropped Huawei P30 Pro or hit it with something hard before noticing it won't charge, it may have malfunctioning hardware. Dropping an electronic device can lead to all kinds of problems, including the possibility that your phone may be dead.

If there are any obvious signs of hardware failure, such as a broken screen, a slanted case or obvious cracks in any part of the body, the phone may require repairs and no software troubleshooting.

If you believe that the reason why your problem with slow charging of your Huawei P30 Pro is hardware in nature, such as when an accidental fall follows or when you hit it with something hard, we suggest you ask Huawei for help and make sure that it can be physically examined.

3) Turn off the device

This is not ideal but sometimes, turning off the phone while charging may work. When there are too many apps running in the background or if a particular app is consuming the battery abnormally, charging may slow down.

To check if this is your case, try turning off the phone, then watch how the recharge works. It usually takes about an hour to load a Huawei P30 from 0 to 100%. In this case, an app or too many apps may drain the battery and recharge while the device is on may appear slow.

4) Restart the device

The next step to troubleshooting you can do is to find out if your Huawei P30 will quickly recharge after restarting. Try to perform a forced restart by holding down the power button for 10-15 seconds. If the recharge works normally, the problem is probably caused by a minor bug.

5) Check the charging port

Other times, Huawei P30's slow charging problems can be caused by the problem of the charging port. It is the part most exposed to the elements and sometimes dirt, foreign objects, fluff, etc. They can block the charging cable during charging.

If your Huawei device seems to be charging slowly, make sure the charging port is clean and there are no visible faults or problems. To check the door, try using a magnifying glass to see more clearly inside. If you notice dirt or debris inside, be sure to remove it using a can of compressed air. Do not attach anything inside to avoid damaging the system.

Another reason why a charging port may not work as expected is water damage. Huawei P30 is water-resistant but may not charge or there may be a slow charging problem if there is water, liquid or moisture in the charging port.

If you received a warning about the liquid or humidity in the door before finding the problem, it is not a bad idea to check the door again, this time for the presence of liquid. To avoid damage to your device, your Huawei P30 will not charge if it detects moisture or water in the door.

Try drying the device for a few hours by cleaning it and leaving it in the sun for a few hours. Water evaporates naturally on its own after several hours.

6) Disable mobile data

In some cases, leaving mobile data enabled during charging can slow down the charging speed. There are no explanations from Huawei on these rare cases, but try to see if this is true in your situation. Instead of using mobile data, switch to wifi and see if there is a difference.

If the fast charge works normally again on the wifi, you should consider a factory reset to fix the problem. The following are the steps for restoring the factory settings.

7) Clear the system cache on Huawei P30

Having a damaged or obsolete system cache can cause performance problems. Sometimes, charging can become erratic due to a bad system cache. To ensure that the device's system cache is in good condition, you can proceed and delete its cache partition. This will not eliminate any of your personal information, so it can be done safely. That's how:

  1. With the phone switched off, press and hold the Volume up and Power buttons simultaneously for at least 10 seconds.
  2. Release the buttons when the Honor logo appears.
  3. Shortly after seeing the logo, the EMUI screen appears with the recovery mode options.
  4. Press the Volume down button to scroll to highlight the Clear cache partition option.
  5. Then press the power button to confirm the selection.
  6. Use the volume buttons to scroll to highlight the next options and the power button to confirm the selection.

8) How to install updates on Huawei P30

Some bugs can develop if the software or apps are not updated. Make sure to install updates if they are available now. Software and app updates generally offer patches to fix existing problems caused by random bugs and malicious software.

If you have not set the device and/or apps for automatic updating, you will have to manually install the pending updates. Here's how to manually check for P30 software updates:

  1. Go to the settings.
  2. Touch System.
  3. Select System Update.
  4. Tap the option to check for updates.

To check for any pending updates to the app you downloaded via the Google Play Store app, launch Play Store then go to the Updates section. You will then see a list of apps with pending updates. Just tap Update to install updates for individual apps or tap Update All to update apps simultaneously.

Don't forget to restart/reset your P30 after installing the updates to ensure that all new software changes are implemented correctly and to prevent any apps from becoming rogue.

9) Verify Huawei P30 overheat

Does your Huawei P30 feel uncomfortably warm to the touch when charging? If so, overheating may occur, which may indicate that there is a problem with the battery or a technical problem with the software. The device overheats if it loads quickly but if the heat becomes unbearable, it is no longer normal.

Be sure to immediately disconnect the device from the charger and allow it to cool. Then try loading it while it is turned off before proceeding to the following troubleshooting steps below.

10) Check the apps that run in the background

As mentioned above, too many apps running simultaneously or in the background can affect the charging speed of the device. Try closing the app and see if it will make a difference during the reload.

To force an app to close:

  1. Open the Settings app.
  2. Switch to Application Manager.
  3. Touch the All tab.
  4. Select your messaging app.
  5. Then tap Force stop.

If you want to close all running apps:

  1. Go to the main screen.
  2. Scroll up from the bottom of the screen until the list of apps appears.
  3. Tap the icon Stop all applications.

11) Restart the Huawei P30 in safe mode

If the device overheats during charging or if the problem occurred after installing an app, there may be a problem with a third-party app. Try starting the device in safe mode to check. In safe mode, no third-party apps should be able to work.

So, if quick top-up works normally in safe mode, you can bet it's a faulty third-party app. Here's how to start it in safe mode:

  1. Turn off the device.
  2. Turn it back on.
  3. When you see the Huawei animation on the screen, hold down the Volume Down button.
  4. You can see the safe mode in the lower-left corner once the device finishes booting.
  5. Now that the device has started in safe mode, load the device and see if there is a difference.

Don't forget: safe mode blocks third-party apps but won't tell you which of them is the real cause. If you believe that an unauthorized third-party app is present in the system, you must identify it. Here's what to do exactly:

  1. Start in safe mode.
  2. Check the problem.
  3. After confirming that it is the fault of a third-party app, you can start uninstalling the apps individually. We advise you to start with the most recent ones you've added.
  4. After uninstalling an app, restart the phone in normal mode and verify the problem.
  5. If your Huawei P30 is still problematic, repeat steps 1-4.

12) Reset of Huawei P30 factory settings

If the charging is still slow on your Huawei P30 after following all the suggestions above, consider deleting your device. There are two methods to perform a factory reset on your Huawei P30. You want to do the first one first if there are no problems going to the Settings menu.

Method 1: Hard reset on Huawei P30 via Settings

If you cancel the phone with the factory settings reset, the information will be automatically deleted from the device's internal memory. The software environment on the device is substantially restored to its original form, just like when it left the factory.

This means that everything you've added to the device such as files, photos, videos, and apps will be deleted. If you don't want to lose irreplaceable data, make sure you create a backup in advance.

There are several reasons why a user may want to restore a device at the factory. If your situation requires a Hard Reset on Huawei P30 and you are able to access the settings menu of your device, then this first method is for you. It's easier to do than the second one below, so this is a reference method for you.
