Why Your phone charger is Overheating (and HOW to Fix It)
Why does the phone charger get too hot?
Does your charger get too hot? I’ve been through this exact experience. One afternoon, I was taking a break while charging my phone, when I suddenly noticed that the charger was so hot that it almost burned my hand! From then on, I started searching – why does my phone charger get too hot ?
Many of us think that this may be normal. But no, this heating is not a common thing. Most of the time it is due to the quality of the charger. Sometimes, the problem with the phone’s battery or charging cable is also responsible for this. I have also noticed on my mobile phone – when it is left on charge for many hours, or when heavy apps are run with the phone turned on, the charger catches fire.
However, it is important to remember that it is normal for the charger to get a little hot, but if it gets to the point where it cannot be touched, then it should be taken seriously. In Bangladesh, we often have power fluctuations, which can also be a reason for the charger to overheat.
Info: While a slight heat from the charger is normal, excessive heat can cause serious damage to the phone and charger.
I have noticed many times that the phone charger gets too hot when charging for a long time or when the phone is being used at the same time. This is a common problem, but can be fatal if neglected.
Info: A hot charger does not necessarily mean danger, but ignoring it can cause danger.
Counterfeit chargers can overheat and increase the risk of explosion. So always use original and branded chargers.
Common causes of charger overheating
Understanding Phone Charger Heat: Causes and Solutions? There can be many reasons behind the charger getting hot, and I myself have known several of them from my own experience. First of all, many people in our country still use fake or cheap chargers to charge their phones. The components used inside them are usually of very low quality. So naturally they get hotter while charging. Some people keep their phone charger and always use their mobile phones—playing games, watching YouTube, and even editing videos. This not only puts pressure on the phone’s processor, but the charger also gets hot while drawing extra power.
Another major reason is the fluctuation of the power flow. In places like our area, the voltage sometimes drops and then suddenly increases. This causes the charger to heat up quickly. Also, if you use a loose cable or an old USB port, more heat can be generated from there. As a result, the charger not only gets hot, but can also break down at some point. So it is very important for us to know these reasons.
Info: Fake or low-quality chargers overheat during charging, which can even pose a fire hazard.
There can be many reasons why a mobile charger gets hot . I have seen this happen more when using a low-quality charger. Also, if the charger is old or has dust inside, it also gets hotter.
- Using a fake charger
- Wet or dusty charging port
- Using the phone charger all the time and charging it
- Voltage fluctuations
Info: Running heavy apps while charging may cause both the phone charger and the charger to overheat.
Harmful effects of mobile charger overheating
Many of us don’t know that overheating of chargers is not just a common problem, but it can also be a threat to our phones and lives in the long run. Once, a friend of mine’s charger got so hot that the charger plug was smelling like fire. Luckily, he realized it at that time and unplugged the charger.
If the charger gets too hot, it has a major impact on the phone’s battery. The battery deteriorates quickly, does not hold a charge, and even swells. In some cases, the circuit inside the charger burns out and major accidents like short circuits can occur. I have also heard of cases where the charger burned out with a sound like an explosion. So, the charger getting hot does not mean that it should be neglected at all. It is not only a damage to the electronic device, but also a safety risk for the entire house.
Overheating of the charger not only damages the charging process, but also reduces the battery life of the mobile. I have even seen situations where the plastic of the charger has melted.
Battery damage
A hot charger causes the battery to deteriorate quickly or not hold a charge.
Possibility of fire
Overheating can cause short circuits or sparking, which can cause a fire.
Charger heating solution
When I find my charger overheating, I have come up with some effective solutions from my own experience, which I am sharing with you. First of all, I always use original and reliable brand chargers. Because I know that even though fake chargers are much cheaper, they can ultimately cause damage to my mobile or myself.
To prevent the charger from getting hot, I don’t use it at all while charging my phone changer, especially when playing games, watching videos, or using social media. This way, there is no stress on both the processor and charging. And if I see the charger getting too hot, I immediately unplug it and put it in a cool place. And I never plug the charger into a power strip, but rather use a direct socket. Finally, if the charger is old or repeatedly overheats, it is best to replace it.
To avoid this problem, I follow the following rules:
- Use a reputable brand charger.
- Don’t use your phone while charging.
- Not using power strips or multiplugs
- Unplug the charger after use
Info: If you feel hot on the phone, unplug the charger and let it rest for a while.
Tips for using phone chargers safely
At one time, I didn’t even realize that there could be certain rules for using phone chargers! But when one charger after another started breaking, and the mobile battery started losing charge quickly, I realized that these things cannot be avoided. So, I have set some rules for myself, and today I am sharing them with you.
The first thing I check is whether the charger is properly inserted into the socket. I never charge with a shaking or loose connection. This can cause sparks. Secondly, I always keep my hands dry while charging and keep the charger away from moisture. Thirdly, I try to use the official charger for my phone changer. And if I have to buy a new charger, it is not from a well-known brand. And of course, I don’t sleep with my phone charger charging all night.
To ensure safe use of phone chargers, I follow the following rules every day:
- Check if the charger and cable are connected properly.
- Keep the charger away from water or moisture.
- Use only official or branded chargers.
How to identify a good charger
I have often been confused when buying a charger in a store—which one is the original and which one is the fake? However, from experience, I have learned some things that even a normal user can easily notice. First, I look at the charger’s package. I check whether the brand logo is clear or not, whether there is a hologram, etc. Then I take the phone charger cable in my hand—it is better if it is strong and thick. Thin cables often tear easily and contain low-quality wires inside.
Another thing that is very important is the charging speed. Real chargers usually charge quickly and stably, and don’t get too hot. It takes a lot of time to charge the phone charger with a fake charger and the phone gets very hot after charging. I always try to buy official phone chargers, especially from online branded stores or trusted retailers. There is less chance of cheating.
As a general user, I know that to understand a good charger, you need to pay attention to the following things:
- Charging speed
- Body temperature (whether it is hot or not)
- Parent company hologram
- Thick and sturdy cable
Comparison chart: good vs bad chargers
When we buy a charger, we only look at the price, but low price does not mean good. I myself once bought a cheap charger and had a lot of problems—the battery swelled, the phone got hot, and even the charger died one day. So now I keep in mind the differences between good and bad chargers. In the table below, I have put together those comparative aspects that you can keep in mind when you go shopping.
Special features Good charger Bad charger | |
|---|---|
| Temperature | Normal (30–40°C) Excessive (over 50°C) |
| Cable quality | Strong and thick Thin and weak |
| Certification | Parent company logo and hologram Fake or unknown brand |
| Charging time | Fast and stable It takes longer. |
Info: A good charger is not only safe, but also increases battery life.
Examples of charger overheating
I was once using a phone charger that looked brand new, but after a week or so, it started getting so hot that it was hard to hold. One day, I noticed black spots around the plug, which was a clear sign of burning. Since then, I have been careful and have started collecting pictures and incidents so that others can be careful too.
In this section, I am giving some pictures that will help you understand the real condition of a heated phone charger. For example, plastic melting, blackening around the port, swollen charger, etc. Seeing these will also create awareness for you. After having this experience myself, I do not neglect any phone charger anymore.
Review: Best charger on the market
There are thousands of phone chargers available in the market now. However, I always try to buy phone chargers from brands that have already gained popularity. For example, Baseus — I have used several of its phone chargers myself and its charging speed and heat control are really good. Samsung Original chargers are definitely the best for Samsung devices.
Those looking for a budget-friendly option can go for Remax or Joyroom . For those who want something truly premium, UGREEN is a great brand. Not only do they look good, but the chargers last a long time. However, no matter how good the brand, it is wise to buy from an official retailer or a reliable online store, rather than from the local market.
Info: A good brand doesn’t necessarily mean expensive—the balance between price and quality is what matters.
I have personally used some good brands of chargers and trust the following:
- Baseus – Fast charging and temperature control
- Samsung Original – Perfect for official devices
- Remax – Budget Friendly and Reliable
- UGREEN – Premium Build Quality
Info: If possible, it is best to use the phone company’s own charger.
Why does the phone get hot when charging? Detailed analysis
I have often wondered about the phone getting hot while charging—is it normal? Or is my phone going bad? Later I understood the details. When the phone charger is charging, a certain amount of electricity flows through the battery. If you watch videos, play games, or use social media on the phone, the processor generates heat separately. The combination of these two makes the phone quite hot.
Using fast charging technology often causes more heating because the battery is charged faster. I once saw a friend’s phone charger get so hot that it turned off while charging. So you should minimize usage while the phone is charging. And if there are any apps on the phone that run in the background and drain the battery, it’s best to close them.
Why does the phone get hot while charging ? The reason behind this is the combination of power flow and processor. I have seen that if you play games or watch videos on the phone charger while charging, the phone gets very hot.
