Phone Battery Going Down While Charging

iPhone battery draining while charging is now a common problem many people face. There are several reasons why it happens. This can be very frustrating, and it will take longer to fully charge your smartphone.

If you are looking for a working solution to fix the phone battery going down while charging, you have to come to the right place. Below are some proven things to do when your phone drains while charging.

The problem can be with your smartphone, the power brick, or even the charging cable.

First, let’s see why

Why My iPhone Battery Is Going Down While Charging

Your phone battery percentage is going down while charging because the power brick is faulty, the cable is damaged, battery health is low, problems with the wall socket, or high battery usage apps are running in the background.

Let’s take a detailed look at some common reasons why your iPhone battery is going down while charging.

Fix Phone Battery Draining While Charging

Faulty Power Adaptor

A faulty power adapter might be the culprit that is causing your phone battery to drain even when it is charging. A defective power adapter will fail to charge your device correctly.

And the good news is that it is straightforward to find out if the problem is with the power adapter.

So all you have to do is disconnect your smartphone from the power adapter, connect it to another device, and see if it charges without any problem.

Also, observe how long it takes to charge the device. Now see if it is taking longer than usual. If yes, you can know that something is wrong with the power brick.

Or if the power adapter was able to charge your other device without any problem, then the issue must be with your device or the power cable.

If your smartphone charger is still under warranty, you may get it replaced free of cost.

Most power adapters that come inside the smartphone box have six-month warranty. If it’s been less than six months since you bought the power brick, you may get in touch with the nearest authorized service center or store and get it repaired or replaced.

In most cases, there is nothing repairable inside a power brick, so they will give you a new one instead.

Damaged Cable

Even if the power adapter is working, your iPhone won’t charge as expected if the cable fails to work correctly. Your smartphone will lose charge even when it is connected to the charger.

It is through the power cable that the charging brick sends power to your smartphone. You should always use a high-quality and original data cable to charge your smartphone.

Faulty Cable

Firstly, start by inspecting the cable for any visible damage. This may include natural wear and tear or cracks that make it not to charge the phone properly.

You should use original or manufacturer-certified cables for charging your device. Similar to the charging adapter, the charging speed also depends on the cable you use.

Try using the same charging cable, charge a different device, and see if it charges without any problem. You may connect it to the same power adapter or use a different one to isolate the problem.

If the charging cable fails, you must buy a new one. No charging cable comes with a warranty of any sort. So you’re forced to get a new one or use a different cable lying in your house.

Ensure The Charging Port Is Clean

Once you are sure that both your power adapter and the power cable are working without any problem, next is to inspect the charging port on your smartphone to see if it has dirt or dust, making it not to charge.

Over time, a lot of dust particles will accumulate inside your smartphone’s charging port. It will block the power from the charging cable from reaching the battery or the circuit.

Take a flashlight and direct it to the charging port of your smartphone. Closely examine to see if there are dust and dirt inside.

Clean The Charging Port

You may use a small toothpick or needle to remove the dirt particles from the port gently. Once the port is free of dust or dirt particles, try connecting the charger and see if you can charge your phone without any problem.

You should be extra cautious when cleaning the charging port. The internals inside could damage very easily if not cleaned properly.

Cleaning the charging port once in a while is recommended.

Wireless Charger Problems

If you use a wireless charger to charge your smartphone, below are some common reasons and fixes to get rid of iPhone battery percentage going down when charging.

Thick Case

If your smartphone case/back cover is too thick, then it will not let your smartphone wirelessly charge.

The coil on the wireless charger and your smartphone should come in contact to wirelessly charge it. If your smartphone case is too thick, the charger won’t be able to charge your device wirelessly.

To see if the problem is with your smart iPhone case, remove it and then place your smartphone on the wireless charging pad. Now see if it charges without any problem.

If it charges, the issue is with your smartphone case, and you need to get a different one that supports wireless charging.

If you are an iPhone user, getting a MagSafe-compatible charger will be a better option since it supports high-speed wireless charging.

Damaged Wireless Charging Pad

If your wireless charging pad isn’t working correctly, it will fail to charge your iPhone. Try placing other devices like a smartwatch or smartphone on the wireless charging pad and see if they charge without any problem.

If they don’t charge, there is something wrong with the wireless charging pad. If your wireless charger is still under warranty, get in touch with your device manufacturer to get it replaced or repaired.

Faulty Wireless Charger Adapter or Cable

Like traditional wired chargers, wireless chargers come with a power adapter and power cable. The power cable connects the power brick and the wireless charging pad.

So ensure both the adapter and the cable is working without any problem.

Wall Outlet Problems

The problem might not always be with the charger or smartphone. It can be with your wall power socket as well.

If the power socket fails to send electricity to the power adapter, it won’t be able to charge your device. Faulty wiring or damaged wall socket are some of the common reasons why the wall outlet fails.

Try connecting a different charger or device to the wall outlet and see if it powers up without any problem.

If your wall socket is faulty, contact an electrician to get it repaired.

Extension Cord Problems

If you use an extension cord to connect your charger, the problem can also be with your extension cord.

Remove the charger and connect it directly to the wall socket to see if the problem is with the extension cord. Connect your smartphone to the charger and see if it charges the device.

Use The Original or Apple Certified Charger

You might have seen all device manufacturers recommending you to use original or manufacture-certified chargers. Using low-quality chargers will do more harm than good. You may get it cheaper, but you are damaging your device in the long run.

If you are using a cheap, low-quality power adapter to charge your device, it’s time to get a new one.

For example, if you are an Apple iPhone user, get the original Apple iPhone charger or some other Apple-certified third-party chargers from brands like Logitech, Anker, or Belkin.

You should also keep an eye on the charger’s watt. If you use a significantly low watt charger to charge your device, it will fail to power it up.

Get a charger that meets your smartphone’s minimum charging requirements. If you are unsure about it, refer to the owner’s manual or the official website to find more info.

Apps Draining Charge

Numerous resource-hungry apps are running in the background, draining your iPhone’s charge. If you have a ton of them opened in the background, then it’s evident that your phone will lose charge even if it is charging.

Before you connect your smartphone to charge, open the recent apps section and clear all apps running in the background.

On your iPhone, swipe from the bottom and hold at the middle to reveal all recent apps. Swipe each app to the top to completely force close it.

Similarly, open the screen time settings of your iPhone and see which app drains most battery.

Now you might wonder how I can know if my battery capacity has significantly lowered. Well, you have that option on your iPhone. It’s called Battery Health.

Hold the power button and slide it to power off your device. Now turn it back on again and see if you can charge your device again without any problem.

We all connect chargers multiple times a day. For the same reason charging port is a part that tends to run into a problem quite a lot. If your charging port is faulty, you will have to take your smartphone to an Apple-authorized service center and repair it.
