Why Does My Phone Keep Overheating When Charging

Are you worried about why sometimes your phone gets hot when charging, like it explodes at any time?

So can overheating phones cause an explosion? The answer is yes,We 've also seen quite a few examples in the past, such as the infamous Samsung Galaxy Note 7 facing problems due to design flaws. The main cause of the explosion is the excessive heat inside the phone. In this case, the battery will be affected by negative ions and even expand. This is usually when the explosion occurs.

This article will explore the common causes of phone overheating and provide practical tips to protect your device, improve its performance, and ensure safe charging. We will also provide advice on how to cool safely when the temperature is too high.

Causes of hot when charging mobile phones:

In fact, there is more than one reason for the hot charging of mobile phones,The following are some of the reasons we found in our research, hoping to solve your doubts.

1.Excessive use of mobile phone while charging

Many people do this kind of behavior, but this is a bad habit. When you use your phone while charging, it causes the device to generate additional heat and puts pressure on the battery.

2.Fast charging

The essence of fast charging is to use higher voltage to support faster power output, which also leads to the generation of additional heat

3. Overcharging

Although modern mobile phones have overcharge protection, maintaining a 100 percent charge for a long time will accelerate the precipitation of lithium metal (Plating), resulting in an increase in battery internal resistance.Experiments show that the cycle life of batteries stored for 6 months at full charge decreases by 19%.

4. Poor ventilation

There are many people who are used to charging their phone under a pillow or blanket, which can lead to a faster rise in temperature and more other risks. Thermal imaging shows that in a 25 ℃ environment, the surface temperature of the mobile phone in a confined space is 7-9 ℃ higher than that in a ventilated environment.

5. Low quality and incompatible charging equipment

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. You may could find the solutions from ROMOSS Power Bank Collections, which offers the convenience of wired and wireless charging methods. 

6. Aging batteries

As the number of charging increases, the internal resistance of the battery will gradually increase, and the heat will increase.

The possible danger of long-term overheating when charging:

Although it is normal to generate heat during charging,However, if the temperature during long-term charging is greater than 40°C, it will cause irreversible damage to your mobile phone hardware and pose a deep safety hazard. Here are the four main damages of a phone that always overheats:

Permanent Battery Damage :

If you do not take effective measures,Then continuous heating will shorten the capacity and service life of the battery.

Reduced Charge Efficiency :

When hot, the phone will limit the current and extend the charging time.

Rapid Degradation of Blocks:

Too high temperature will produce certain chemicals in the phone,Accelerate the loss of precision electronic components.

Poor performance Display :

An overheated mobile phone may lag or crash during use, because the heat of overheating will generate pressure on its internal components.

Now that we understand the causes, let’s evaluate the risks at different temperature levels.

Level 4 Risk Warning for Overheated Mobile Phone

Temperature Range	Risk Level	Potential Consequences
0 ° C - 35 ° C	Safe Zone	No risk,Best Performance
35 ° C - 45 ° C	Warning area	Accelerated battery capacity decay (1%-2% per month)
45 ° C - 50 ° C	Danger Zone	Motherboard Capacitance Aging, Screen Debonding
\>50 ° C	High-risk zone	Thermal runaway risk (expansion/combustion)

If your phone is hot at this time,Here are the most simple and easy to implement tips:

Stop charging immediately

From a hardware point of view, when the phone is hot, please stop charging to avoid continuous accumulation of heat

Close all running applications and stop using it

In terms of software,Closing applications running in the background helps reduce the load on the phone's processor and battery, minimizing heat generation

Remove the phone case

Do you still remember the above mentioned that poor ventilation leads to fever? Removing the phone case is the simplest way to directly allow the phone to provide ventilation.

Put your equipment in the shade

Keep away from direct sunlight and near air conditioning or vents.

Warning: Do not put your phone in the refrigerator! Quenching may cause condensation to damage the components.

Use cooling tools

The recommend efficient cooling tools here are thermal pads or fans,These two tools can keep the phone at a lower temperature while charging by creating more airflow.

Put phone in airplane mode

Airplane mode will significantly reduce the amount of power required to charge the phone, and turn off functions such as Wifi, Bluetooth and location services, which can reduce the pressure on the phone's battery.
