Have you used any fast charger on a non-fast charging smartphone? If you are willing to use or have already used it, you may have concerns about your phone.
Using a fast charger on a non-fast-charging smartphone does not damage or affect battery life in the short term. However, fast chargers can heat the battery fast, and using these chargers frequently for a long time can affect the battery life, resulting in low charge capacity.
Let’s look at some details about this topic to clarify your doubts about using a fast charger on a non-fast-charging smartphone.

What happens when you fast charge 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, using a 33 Watt charger to charge a phone typically charges 18 watts. The phone will take the input of a current of 18 watts.
No matter how powerful the charger is, the chip inside the phone has been designed only to take the input current of 18 watts.
But the power supplied to your phone is 33 watts, right? 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.
Does a fast charger heat the smartphone?
Usually, the smartphone’s average temperature is between 35 – 50 °C, and if you use it heavily, it can go beyond 50 °C, affecting the battery and lowering 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 the 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 in phases.
The first phase charges the phone slowly, the second phase charges it rapidly, and the third one charges 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 or three times will not damage your battery, but if you frequently use the other charger for 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 to see the charger’s output current whenever you charge your phone with any other charger. Don’t use it if it does not match your phone input current.
What to do when you are not getting a suitable charger for your smartphone?
It does not mean you can use any charger if you are not getting one for your smartphone. If you have read some previous posts, I told you about using a compatible charger for your smartphone if you are not getting the original one.
Compatible chargers are readily 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. Go with the charger with good reviews, and your smartphone will work fine.
Remember, don’t use a fast charger when you don’t have a charger to charge your phone. 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.
