How To Fix Samsung Smartphones Won’t Charge? – 10 Fixes

My first Android smartphone was Samsung Galaxy S Duos, which I purchased in 2012. Since then, I have used many Samsung smartphones. I’m currently using Samsung Galaxy Z Flip 4 as my secondary phone (because I love that flipping experience).

A common issue I have noticed with Samsung smartphones is the battery charging problem. Many times my Galaxy Z Flip 4 refuses to charge when I insert the charging cable.

If your Samsung smartphone is not charging, this guide is for you. Here I’ll share some common reasons why a Samsung phone won’t charge and how to fix that.

Why is my Samsung Galaxy Phone Won’t Charge?

The most common reasons any smartphone doesn’t charge are – a faulty charging cable, a dirty or clogged charging port, a defective power adapter or wall outlet, or any third-party apps interrupting the charging module.

However, these issues can be easily rectified and fixed. Read this guide to fix the charging issue.

How To Fix Samsung Phone Not Charging?

If your Samsung Galaxy smartphone is not charging when plugged in, you should follow these steps to fix the issue-

Use The Original Charger

Samsung Adapter

The first thing you should try is – to use Samsung’s original charger to charge your smartphone. Many smartphone brands provide different wattage power adapters.

If your Samsung Galaxy doesn’t charge, then use Samsung’s original charging cable and the power adapter to charge your smartphone.

Inspect Your Cable

Damaged USB Cable

The charging cable is the most vulnerable part because we use it daily but don’t store it safely, due to which the charging cable gets damaged and frayed. You can use a different USB type C cable to charge your phone.

I would advise you to check your charging cable thoroughly and replace the cable if you notice any sign of damage.

Change The Power Source

If you’re using your laptop USB hub to charge your smartphone, you might face a charging problem.

The power output from a laptop USB hub is generally lower than the rated power input of your smartphone. Hence it won’t charge your phone when plugged into the laptop.

Clean Your Charging Port

A clogged charging port with dirt and debris is a common reason seen in many cases why smartphones won’t charge when plugged in.

If you haven’t cleaned your charging port for a long, you should inspect and remove any debris clogging the port.

You can use a toothpick or non-metallic object to remove debris and clean the charging port with isopropyl alcohol.

Don’t forget to power off your smartphone and be gentle while cleaning the charging port, and don’t use any metal to remove the dirt and debris.

Inspect Moisture in USB Port

Samsung smartphone uses a sensor to detect moisture inside the USB port and stop charging to prevent serious hardware damage.

If your Samsung phone was accidentally dropped into water, you should dry it before plugging it in for charging.

Leave your smartphone in a dry place for three to four hours to dry off any moisture content inside.

Do not put it inside the rice bag or in direct sunlight or a blower to dry off the moisture. It may lead to serious hardware damage on the motherboard.

Clear USB Settings Cache

If your Samsung phone is not charging and notifies “moisture detected won’t go away,” but you’ve dried it, then clear the cache of USB Settings.

  1. Go to Settings.
  2. Open Apps from the settings options.
  3. Allow system apps from the filter option.
  4. Scroll down and tap on USBSettings.
  5. Tap on Storage.
  6. Hit on Clear Data and Clear Cache.

Cool Down Your Device

If you’re living in hot weather, your phone will sometimes heat up when you multitask.

If your phone is hot, then the temperature sensors will cut off the current supply, and your phone will not charge.

It’s better to shut down your phone and leave it in front of an Air Conditioner or cooler/fan to cool it down. Once your phone temperature drops to normal, plug in the charger, and it’ll charge.

Update Your Software
