Why is My Phone Charging Slow? Here is Solution

When your Android is charging slowly, it can put you in concern. Fast charging Android phones make your work easy. Therefore, whenever your phone is charging slowly, you must identify the reason behind it.

There can be lots of reasons. Some of the reasons are the following:


Damaged USB Cable

A proper USB cable plays a vital role in charging your Android phone. Also, they are very delicate accessories in your charging kit.

After a long time of use, they get fragile. They are used very roughly. We carry them in our bags. They get Tangled with pointy or sharp stuff there. Even while taking off the phone from charging, we carelessly pull out the USB cable.

All these incidents can cause tears in the outer cover and the thin wires inside. This will disrupt the electricity flow. Also, this kind of wearing can cause short circuits. To avoid any accident, always check for any tear or scratch on the USB cable.


Adapter With Insufficient Amperage

Amperage is the parameter that determines how much electricity is flowing from your adapter to your device. An adapter with low I amperage means it will take much time to charge your device. Low amperage means low electricity flow.

Your phone is designed to accept a fixed amount of energy. An adapter with higher amperage doesn’t mean your phone will take more electricity. Rather, adapters with higher amperage help transfer electricity faster into your battery. Therefore if you are not using the default adaptor that came with your phone, check the amperage on the third-party charger before plugging it into your phone.

For example, if your phone accepts amperages of 2 amps, the adaptor must be 2 amps or higher. Adaptors for Android devices are not that expensive. Therefore, it is easier to change your adaptor than to change your phone.

Dusty Charging Port

We take our Android phones to all kinds of places. Therefore, there is a chance of dust build-ups in small crevices of Android phones.

Even though we clean the phone screen regularly, we avoid cleaning the small input zones. That includes the charging port. For this reason, dust builds up inside it and creates a barrier between the energy transmitters. Also, the charging port might get damaged due to friction from the dust particles.

If you find your USB port sits loosely in the charging port, then your charging port might have some tearing inside it. These issues are fixable with some easy care.

Unstable Power Source

If you’re using a wall outlet to charge your phone and it’s charging slowly, you should check the power supply. A continuous flow of electricity during the phone charging is essential for battery life. Also, the interaction during the charging due to power cuts slows down the charging.

When someone charges their phone without a wall outlet, like Power Banks, laptops, or other stable power sources, it slows down the charging process. These are secondary sources of power, making them weak for charging your Android device faster. Charging your phone from a wall outlet takes half the time of charging it from a secondary source of power.

Phones Incapability

Every Android device has a specific limit for power intake at a time. If your phone is charging slowly from thy beginning, it might not be configured as fast charging.

This doesn’t mean that your phone has issues. Rather the configuration of the phone doesn’t allow it to charge fast. In this case, to get the best charging performance, try to use a better adaptor. Also, maintain synchronization of power between all the charging kits.


Background Apps

We usually don’t clean the background apps when we put our phone in charge. Therefore even when the phone is in charge, it tends to use the energy. In the end, the charging process gets slower. If your cellular data connection is active during the charging process, it can affect the total charge time.

Many apps work even when the Android device is in sleeping mode. While charging the phone, this kind of app slows down the charging process. This kind of dynamic app is also the reason why your phone can’t hold a charge for a long time.


Heavy Usage

Using your phone throughout the day can cause issues with your phone’s energy consumption. In the long run, your phone will tend to consume more electricity than usual while charging. Ultimately this will slow down the charging.
