Why Does My Phone Get Hot When Charging? Top Causes and Solutions

Smartphones have become an essential tool for everything from communication and entertainment

Smartphones look very futuristic, but they have some quirks. One common issue is that my phone gets hot when charging. not to work and navigate in modern lives. However, just as smartphones look super futuristic, they do have their peculiarities; why my phone gets hot when charging is one of the most common issues smartphone users face.

This phenomenon can be confusing, concerning, and even frustrating. You, like most others, certainly have asked yourself at one time or another why your smartphone heats up sometimes while charging, or perhaps it is due to a device malfunctioning. This article will lead you through some of the most common causes of overheating phones and what you can do for your device to remain cool and in the best working state.

 Why Does My Phone Get Hot When Charging?

• Before we talk about the causes and solutions, let’s go through the cause of why the phone gets hot while charging. Charging the smartphone converts electrical energy into chemical energy stored in the battery. It is not feasible perfectly since conversion generates heat as a byproduct; however, it is fairly manageable for most cases, and it does not generate long-term problems. In case your device starts heating really and too often, then this can be an alarming symptom.

Let’s dive into some of the most common causes behind why your phone gets hot when charging

 1. Fast Charging Technology

• One of the main reasons why your phone heats up when charging is through fast charging technology. Most modern smartphones can now support fast charging. Thus, it can charge your smartphone quickly, and sometimes this technology even can charge up to 50% from zero battery status in just 15-30 minutes. This feature might be very convenient; nevertheless, it heats up very intensely.
• That is, rapid charging works by giving more power to the battery within a short span, heating the internal components of the phone, too. For example, Qualcomm Quick Charge and USB Power Delivery (PD) can force more voltage or amperage into the battery in a phone, which produces heat.
• Typically, phones feel a little warm if they use fast charging. However, the heat can be uncomfortable, and the phone may even get too hot to let you show some problems with the charger or perhaps the battery.

 Solution

• If you want to minimize the heat generated by fast charging of your phone, then you might want to adopt slower rates of charging. In addition, you can unactivate fast charging in your phone’s settings (if it has this functionality), or you can resort to using a slower charger. Moreover, by putting your phone on airplane mode, or closing all applications running in the background, you can also let the battery regenerate without as much burden, thus hindering overheating.

2. Charging Your Phone While Using It

• Another common reason why your phone gets hot while charging is that you use the phone extensively while plugged in. Be it playing games or video play or running apps that are big in graphics like video editors or games that load a lot, your processor, GPU, and the battery work much harder, thereby creating more heat.
• Charging while on a call with your cell phone attempts to charge the battery while trying to power the cell phone’s operations, thus leading to overloads, which could generate excess heat. Some applications could also be running in the background, using some of the resources, further dragging the processor and the battery.

Solution:

Overheat your phone as little as possible. Avoid being so zealous with your phone when charging it. Even if you just can’t wait to use it, limit applications that consume much of the phone’s resources, such as playing games or opening multiple apps. Close the applications if you will not utilize them to prevent overloading the processor.

 3. Faulty or Low-Quality Charging Accessories

• If you are using third-party chargers, cables, or adapters that are not certified by your phone manufacturer, it is the reason why your phone gets hot when charging. The highest risk it can cause is inefficient power transfer that creates too much heat.
• Incorrect charging cables or adapters result in inconsistent voltage or power supply to the phone. Internal components of the phone can start overheating, which can compromise both the charger and cell phone life as well.

 Solution:

Always use the charger and cable provided with your phone or otherwise certified third-party accessories that are compatible with your device. Avoid off-brand chargers that do not comply with the safety and power standards set by the official organization. For charging accessories classified to be old or damaged, replace those with new, quality ones.

 4. Age and Health of the Battery

• As your phone ages, the battery begins to lose efficiency. A battery no longer in prime condition cannot always charge as efficiently as it used to, generating heat in the process. The lithium-ion batteries commonly found in smartphones degrade over time; their ability to store and transfer energy decreases.
• Further, overcharging causes a battery to heat up more easily because it cannot manage its power load. Some of the main reasons why your phone gets hot when charging include a significant loss in battery health
• .

Solution:

Check the condition of your phone’s battery; most modern smartphones are equipped with an inbuilt monitoring system. If your smartphone’s battery life has notably degraded (below 80%), you might want to consider replacing it. The majority of manufacturers will replace the battery on your phone to assist with your smartphone’s responsiveness and cut down on overheating while charging.

 5. Background Apps and Processes

The other reason why your phone heats up while charging is due to running applications in the background. Most applications keep running and using system resources after you close them, either syncing some data, updating, or even sending notifications. Such applications put a massive load on the CPU and GPU, meaning even more heat production when charging.

Other apps, especially those that always run location services or access the internet, will also contribute to heating up because they need constant processing time.

Solution:

Moreover, you should frequently close the background apps running on your phone to prevent it from becoming too hot due to excessive work. Also, see the battery settings for any app that may consume a lot of power or run processes in the background of your phone. Disable auto-updates, turn off unnecessary notifications and prevent location services to avoid overheating.

 6. Environmental Factors

• Another part is that the environment you charge your phone in may also make it hot. Charging your phone in a hot area, which may be exposed to direct sunlight, in the car, or an under-thick phone case can cause the heat from that environment not to be dispersed but to be trapped by the phone, making the phone overheat.
• Besides, putting the phone in a case when charging traps the heat surrounding the device, which exacerbates the problem of overheating.
• Solution:
• You can also try charging your phone in a cool, well-ventilated area, away from direct sunlight or heat sources. If you charged it in a case, remove the case so it can breathe. Try using a fan or putting the phone on a cooler surface, like a desk or table, to let it cool down.
• Sometimes, your phone heats up while charging simply because of some software glitch or bugs. Maybe a recent update or something inside the phone’s operating system causes power to be mismanaged, which later becomes overheating. You are also using apps that do not support the latest version of the software.

 Solution:

Ensure that you have the latest version of software installed on your phone; manufacturers usually release updates containing bug fixes and performance optimizations. If your phone has recently updated its software and has been overheating, then you could try and check again for other patches or even do a factory reset after back-up to resolve this issue.

 8. Charging While the Phone is Full

• It’s tempting to keep the phone plugged overnight, especially if a person is heading to bed with a low battery; however, charging a cell phone when the battery is already fully charged leads to unnecessary heating. Most of today’s smartphones have features that stop charging once the battery is full. However, if the phone starts pulling energy from the charger once it’s reached its capacity which might be a problem with the software or the battery, it may lead to a heating-up issue.

Solution:

Unplug your phone once it reaches 100% to prevent heat accumulation. There are also gadgets with features that could make it chargingly intelligent, for example: charge only when needed or lower the charging rate to prevent deterioration of the battery.

Conclusion: Keep Your Phone Cool and Functioning Well

• Why does my phone get hot when charging? It is quite normal for a little warmth while charging, but excessive heat could be a deeper problem. Once you understand some of the usual causes of overheating and apply the solutions that we have outlined, your phone should stay cool, its battery lifespan will increase, and it will function well.
