Samsung Fast Charging Not Working? Try These Fixes

Fast charging is the perfect feature for people who hate to wait for their phones to get powered up before leaving for an evening out with friends and family. After just a short charge time, you can use your phone for hours. Samsung includes fast charging in many of its most popular phones.

Although it is a big selling point for Samsung, it can also be problematic at times. Here are a few fixes you can try if fast charging isn’t working on your Galaxy phone.

1. Your Charger Doesn’t Support Fast Charging

For fast charging to work, your phone charger must support it. The charger that comes with your phone likely does, but you may have to buy one separately, as with Samsung S21.

A charger that doesn’t have a label that says Quick Charging, Adaptive Fast Charging, or something similar signifies that it isn’t compatible with fast charging. This will charge your phone a lot more slowly.

The USB cable with these chargers is also quite fragile, and this can also impact its performance. So, do take care of these two points before implementing other fixes.

2. Clean the Charger Port

Another possible reason fast charging does not work is the accumulation of dirt or residue in the charging port. Your charger can’t operate at its full capacity or even at all if it has dirt or lint in it.

Using a toothpick or needle, remove any dirt, grime, or other residues. You can also use a cotton swab and rubbing alcohol inside the charging port in circular motions. Afterward, put it in a cool, dry place for at least an hour. Don’t worry about the liquid in the dock; it will naturally evaporate.

3. Change the Charging Outlet

There is also the possibility that a faulty outlet does not supply enough current to support fast charging. Your charger won’t be drawing the power at the required rate to fast-charge your phone in the absence of sufficient power.

Try a different charging outlet to see if that makes a difference.

If you are using any other power source, like an external power bank, make sure it has enough wattage to support fast charging on your Samsung device.

4. Charge Your Phone in Power Saving Mode

Nowadays, every Galaxy phone supports a power-saving mode. It can dramatically cut down on background apps and processes that eat up your system resources and helps your phone’s battery last longer.

With the minimal battery draining, it may also quicken the charging process. Therefore, consider charging your smartphone in power-saving mode. You can find it at Settings > Battery and device care > Battery > Power saving mode.

If fast charging worked fine a few days earlier, see which new apps you installed recently on your phone. When you find the ones that might be consuming a significant amount of power, try stopping or uninstalling them temporarily to verify that they are the culprits.

Lastly, if you keep the anti-virus apps running in the background, you can also turn them off to see if that solves the problem.

5. Turn Off Mobile Data or Wi-Fi

If you don’t want to keep switching into power-saving mode every time you plug in your phone, turning off Wi-Fi and mobile data can be a good compromise. Even when you aren’t using your phone, these connections might still be drawing the power. Turning them off may speed up the charge time of your phone.

To make things easier, always put your phone in Airplane mode before connecting your charger to speed up the process.

6. Clear the Caches

Cached data can corrupt over time, resulting in sluggish system performance. In such a case, charging time might increase with a drop in your battery performance. Clearing your caches will not only help you fast charge your phone since it will not drain your battery, but it will also improve the overall performance of your device.

New Android smartphones don’t let you clear the cache at once for all apps. So, you’ll have to do it separately for each app. Here is how you can do that:

1. Go to your phone’s Settings.
2. Tap on Additional Settings and navigate to Storage. (The Storage folder location might be different in your phone.)
3. Go to Apps.
4. Tap on the app you wish to clear cache for. (Snapchat in this example.)
5. Lastly, hit Clear cache and you are good to go.

7. Do a Factory Reset as the Last Option

In case none of the fixes work, you can try factory resetting the phone. As the name suggests, a factory reset returns your phone its to default settings.

This gives your phone a fresh start and may solve the problem of fast charging not working. Since the process deletes all of your data, create a full backup before you perform the reset.

Samsung Wireless Fast Charging

Some Samsung phones support fast wireless charging, but not all models. You can buy a wireless charging stand separately to fast charge your cell phone only if it supports wireless fast charging.

Start Fast Charging Your Phone Again

One of the above fixes will help you fast charge your phone again. However, if none of the above fixes have worked, there may be a hardware issue preventing your smartphone from fast charging.

If your Android phone lacks a fast charging feature, there are still ways to speed up your phone’s charging process.
