Samsung Adaptive Fast Charger Not Working? [7 Quick-Fixes]

When it comes to current cell phone trends. Many people will say that Samsung has the best fingerprint and fast charging features. Fast Charging is one of the features that is considered important when everyone has fast-paced mobility. 

But like some existing cell phone features, fast charging can also be problematic. So when your Samsung adaptive fast charger doesn’t work, you can use these tips in this article to solve your problem.

What is fast charging and how it works?

It is a type of technology that manages to charge a battery at a higher speed than usual. This is an advantage when you need to charge your phone quickly. Usually, this happens because the “power” is increased so that the battery recharges faster by increasing the amperage, the voltage, or both. This is based on a series of circuits that are present both in the charger and in the phone itself, batteries are generally made up of two chemicals. 

The battery after getting charged carries a reverse process. In which electrons are put in and, for this reason, the chemical compounds start reacting and return to their originality. This is when they are capable of beginning the initial process. They make generate electrons by merging together that are used to power the circuit that makes the electrical components work. This is how all normal chargers and phones work, with those that have fast charged, the big difference is that power administered than a normal charger is more.

This does not mean that as a solution you can put a fast charger on your mobile. It does not work like that. Although there are fast charging cables, electronic devices have a regulator that limits the amount of power they can receive from their charger. Also, if you give it a lot more power than it can handle it is very likely that you will end up breaking the phone.

Some chargers allow you to charge 50% of the mobile battery in 10 minutes or even 100% in 20 minutes. With any normal charger, we would need more than 1 and 2 hours to achieve these results. Therefore, they are an advantage when we need to charge the phone quickly and especially for batteries with little capacity. Although there are various factors that can affect the fast charging of your charger:

  • A Broken USB Cable
  • Any glitch in the software
  • Fast Charging disabled
  • Fault in the Adapter

And many more factors. So, if your Samsung adaptive fast charger is not working then you can follow these methods to get a solution for your problem.

Things to check Before Proceeding

  1. To get started, you need to make sure that the phone is running the latest Android version before moving on to the troubleshooting steps that we are going to recommend. So, first, download any update if present, and secondly check whether your charger is physically damaged. 
  2. There are two parts in a charger which are the USB cable and the AC adapter (the head). The cord is usually quite fragile and easily damaged, so it is better to try to use another cable. You can try using another adapter to charge your phone.
  3. It is important to know that if the problem is with the battery and the battery is worn out or damaged, our workarounds will not do much for you. In this case, it will be necessary to think about replacing the Lithium battery of the phone altogether to find a normal charge and an initial autonomy on the Samsung device.

If you are sure of the physical integrity of your battery, you can go directly to troubleshooting solutions.

  • Check the condition of the charger

It may not be your phone that is damaged, but the changer, be it the USB cable or the charger head. 

A damaged charger can seriously affect the speed of charging. 

So, check your Samsung adaptive fast charger properly and try to identify any damage. If you found any then it’s time to get it replaced.

  • Charge from another outlet

There are times when the problem is caused by an outlet which doesn’t work properly.

To rule out this possibility, you need to try plugging the charger into a different outlet and see if there is a difference. 

Note that it is best not to plug the AC adapter into an extension cord, but rather to plug it directly into the outlet to avoid the hassle.

  • Check the phone charging connector


The presence of dirt or residue stuck in the charging port (charging connector) of the phone can usually cause problems with the charging socket. 

Make sure that this component is clean and free of any dust, grime, or other residue by using compressed air can or a cotton swab.

If the port in question gets wet, you should first dry it by leaving the device in a cool place for a few hours. 

The liquid on the charging dock will evaporate naturally. Then check if the problem persists.

You can try to connect the device to the USB port of a computer. If it takes charging normally even though it’s slower, there must be some problem with the fast charging pin of the charging connector. 

If this is the case then you need to buy a new charger. Here we have sorted the task for you by reviewing the best magnetic charging cable. It will help you make the right choice.

  • Boot into Safe Mode

There are cases where an app you downloaded and installed can cause this issue with battery charging. To eliminate this possibility, start the mobile in safe mode where only the preinstalled (basic) applications are executed. To do this, follow the following procedure.

  • Shut Down the Mobile 
  • Keep down the Power button for a few seconds.
  • When the word “SAMSUNG” appears on the screen, leave the power button and hold down the volume down key until the device restarts.
  • The safe mode appears in the phone’s bottom left corner.
  • Release the Volume down key when you see “Safe Mode” at the bottom left of the screen.

If the problem does not occur in this mode, it may be caused by a third-party application that should be removed as soon as possible.

  • Clear Cache 

Many times cache data gets corrupted which leads to slow functioning of the whole device including charging. 

So, it’s better to try clearing cache once and your phone will become slightly fast for sure. 

It will also affect the speed of fast charging and will make it much smoother.

  • Check If Fast Charging Is Enabled

Many times the fast charging feature is not enabled in the Samsung phone which leads to slow charging. 

So, go to settings and search for the fast charging option in the search bar and enable it if it is disabled.

  • Turn off data and Wi-Fi

If there is something that drains the battery, it is that the smartphone does not stop connecting to one side and the other. 

It might be for social media, updates, or whatever. In this case, the next step that will save us more waiting time is to directly leave it without data.

In this way, it will not connect to 3g / 4g networks, etc., or to Wifi networks.

Factory Reset

If you have checked everything and it turns out that the fast charging feature is still not working. So the only best way is to do a Factory Reset. Restore all settings of your phone to factory settings. 

The reason is, the damage to fast charging is a sign that something is wrong with the Android software system. We have all ever needed to charge our Android phone’s battery faster because we had to go somewhere. In fact, you despair when you put it to load with the rush to leave and you do not stop looking at it. 

Final Words

After trying all these methods if your charger is still not working properly then probably there is something wrong with your charger or your device. It will be better to go and get it checked in the showroom. Many times Samsung adaptive fast charger doesn’t work because of hardware failure in the device.
