Do you ever notice that your phone gets hot while charging? This is a common issue, and there are several reasons why this happens. In this comprehensive guide, we will discuss the six most common reasons why phones get hot when charging and explain the potential risks associated with your phone overheating, ways to cool it down and reduce the risk of damage, plus answers to frequently asked questions about charging devices.

Why Does My Phone Get Hot When Charging?

A hot phone while charging is a relatively common occurrence and can be due to several factors. Here are some of the most typical causes for this issue.

1. Overcharging: When your phone is plugged in for charging and the battery reaches 100%, many phones are programmed to continue to feed power into their batteries even when they’re full. This excess energy has nowhere to go and will cause your device to heat up.

2. Fast Charging: Fast charging can also cause your phone to heat up when plugged in as the device is quickly drawing power from the charger. This process generates a lot of heat, so if you’re using fast charging, it’s best to use an adapter with a high amperage and voltage rating to reduce overheating.

3. Poor Ventilation: If your device doesn’t have enough space or ventilation around it when charging, the heat generated by the phone's internal components can't escape and will cause your phone to overheat. Make sure there is plenty of room for air circulation around your device while it charges.

4. Poor Quality Chargers or Cable: Low-quality or counterfeit chargers or cables can also be responsible for overheating. If you’re using a charger that wasn’t specifically designed for a phone, it could lead to excessive heat production when charging.

5. Overuse While Charging: Using your device while it’s charging can generate extra heat as well as stress on the battery. Excessive usage while charging can cause your device to overheat and should be avoided if possible.

6. Aging Batteries: Just like all other batteries, smartphone batteries degrade over time and loseFast charging generates more heat due to the higher voltage and current being supplied to the device.

What Could Happen If It Always Overheats?

The four main damages of a phone that always overheats are:

1. Permanent Damage to the Battery: Continuous overheating can reduce your battery’s lifespan as well as its capacity and cause permanent damage.

2. More Rapid Degradation of Components: Excessive heat can harm delicate components within your phone, making them wear out more quickly than they should.

3. Reduced Charging Efficiency: A hot device will take longer to charge, reducing the efficiency of your battery’s charging cycle.

4. Poor Performance While in Use: An overheated phone could have problems with lagging or freezing while in use due to the strain on its internal components from excessive heat production.

How to Keep Your Phones Cool When Charging?

Here are six surefire methods to keep your device cool while it charges.

1. Avoid Overcharging: As mentioned earlier, overcharging your device will cause it to overheat and damage its battery, so make sure you only charge your phone for as long as necessary. More importantly, Once your phone is full, unplug it to avoid overheating.

2. Use a High-Quality Charger & Cable: Only use chargers and cables that are specifically designed for phones in order to ensure safe, efficient charging without excessive heat production. For example, Anker charging cables come with MFi certification for flawless compatibility with Lightning devices, ensuring safe charging at the highest possible speed.

3. Put the Phone in Airplane Mode: Putting your phone in airplane mode will reduce the amount of power it needs to charge, which can help keep temperatures low. Turning off features like Wi-Fi, Bluetooth, and Location Services will reduce the strain on your device’s battery and keep it from overheating when plugged in for charging.

4. Remove Your Phone's Case: Taking off your phone’s case before plugging it in for charging can help keep your device cool by providing better ventilation around the body of the phone.

5. Place Your Device in a Cool Place: Try to avoid placing your phone in direct sunlight or near any other source of heat while charging. Putting it in a cool spot can help keep its temperature down even when plugged in for extended periods of time.

6. Switching to a Wall Outlet: Charging your device in a wall outlet rather than relying on USB charging will help reduce overheating as it can provide more stable power without the risk of sudden power surges or drops.

Conclusion

Heat is a major issue for smartphones and can lead to serious damage if not addressed properly. It’s important to understand how heat is generated in order to prevent any unnecessary damage from occurring. While there are some unavoidable causes of overheating, such as fast charging or high usage while plugged in, following the above tips can help you reduce the chances of your device overheating and protect it against any potential damage. By taking simple steps like using the right charger, avoiding overcharging, and putting your phone in airplane mode when charging, you can keep your smartphone cool and running smoothly for longer.

FAQ about Why Does My Phone Get Hot When Charging

Is it Bad if My Phone Gets Hot?

It is generally considered normal for devices to become warm during usage and especially when they are being charged due to increased demand for power from their battery. However, if it becomes too hot then this may indicate an underlying issue that needs addressing immediately before further damage occurs.

Can an Overheated Phone Cause a Fire?

Yes. Prolonged exposure to extremely high temperatures can cause serious harm both internally (in terms of damaged components) as well as externally (as in cases where batteries catch free). To avoid these risks make sure you follow safety procedures such as keeping external sources of heat away from devices while they are being charged and avoiding overcharging them at all times to greatly reduce any chances of these scenarios happening unintentionally.

Why Don't Charge My Phone in Bed?

While smartphones come equipped with special safeguards that prevent them from reaching dangerously high temperatures during operation, most advise against placing them directly onto soft surfaces such as beds. Due to potential complications arising from having no open-air circulation around them, which may lead faster increase in temperature and more of other risks.
