What happens when you fast charger on a non-fast charging smartphone?

When you use a fast charger to charge a non-fast charging smartphone, you will experience a gradual increase in the temperature of your smartphone, and the battery heats up.

For example, if you use 33 Watt charger to charge a phone that typically charges 18 watts. The phone will take the input of a current of 18 Watt.

No matter how powerful the charger is, the chip inside the phone has been designed to that it will only take the input current of 18 Watt only.

But the power supplied to your phone is 33 Watt isn’t it the rest of the 15 watts do not go anywhere but convert in the form of heat, which can affect your smartphone battery life. The more power charger you use, the smartphone will heat up more.

Does a fast charger heat up the smartphone?

Usually, the smartphone’s average smartphone temperature is between 35 – 50 °C, and if you use it heavily, it can go beyond 50 °C, which can affect the battery and lower the smartphone’s performance.

The same happens when you use the charger of other brands, which has a different output level of power, and when you use it with your smartphone, which has some other input level of control, you can expect to rise in temperature of your phone while charging.

That’s why most smartphone brands recommend using their own manufactured charger rather than any other brand.

But when you use a fast charger on a fast-charging phone, it does not heat it. When the charger is first connected to the phone, it charges into phases.

The first phase is charging the phone slowly, the second phase is charging it rapidly, and the third one is charging the device again slowly to avoid overheating.

Is using a fast charger on regular phone damage your phone battery?

Undoubtedly, using a charger on a regular phone will decrease the battery. As you all know, the temperature reduces battery life.

Using two three times will not damage your battery, but if you frequently use the other charger for long about more than a month, you will experience that your battery will degrade a lot faster than it used to have before you used it a month ago.

Now make sure whenever you charge your phone with any other charger, see the charger’s output current. Don’t use it if it does not match your phone input current.

Fast chargers are specially made for smartphones that use fast charging technology. Inside the smartphones, fast charging tech is used, such as Qualcomm quick charge, VOOC, Dash Charging, etc.

What to do when you are not getting a suitable charger for your smartphone?

It does not mean that you can use any charger if you are not getting a charger for your smartphone. If you have read some previous posts, I had told you about using a compatible charger for your smartphone if you are not getting the original one.

Compatible chargers are easily available in the market. They are far better than using a fast charger on your phone.

If your smartphone is old, there is a very low possibility of finding an originally manufactured charger. You can use another third-party brand charger. They might charge your phone slow but not damage the battery life.

You can also visit Amazon to buy a compatible charger for your smartphone. Just go with the charger with good reviews, and your smartphone will work fine.

Final words

Remember next time when you don’t have a charger to charge your phone don’t use any fast charger use a charger that supplies low power. It’s okay your phone will charge slowly but at least it will not heat and damage the battery.
