There is a lot of news running on smartphones blasted due to overheating. The recent incident was with Samsung Galaxy S10. So, in this article, we will see why smartphone overheat, can overheating damage our smartphone, and how to prevent our phone from overheating
There can be a lot of reasons that your smartphone gets overheated. Now, most of the CPUs are designed to absorb the excess amount of heat. The CPU slows operating speeds to cool down your phone and prevent it from damage. Some reasons for your smartphone heating up are:
1. Due to the outside temperature. when you are using your phone on the direct sunlight.
2. Running intense graphics games or video rendering.
3. Many apps are running in the background.
4. Constantly using your phone for a long time.
5. Running high CPU demanding apps.
6. Charging your phone up to 100%.
When a smartphone overheats, it can be very dangerous for a smartphone. It can affect many components of a smartphone. The two major parts that highly get affected by overheating are:
Especially when you are running heavy graphics intensive game or have many apps in the background can heat your CPU to a large extent. Continuously overheating your phone can make give permanent damage to your phone. You can experience poor performance because modern chipsets are build in a manner that when CPU is getting overheated, CPU slows down processing speed to cool down.
The second issue with lithium-ion batteries is that they are heat sensitive. If you are using your phone directly on the sunlight, you might unknowingly harm your phone. It speeds up the aging process whenever your battery is subjected to overheating. This is obvious when you start to realize that your battery charge does not last as long as it was before.
Why Smartphones Overheat?

2. Running intense graphics games or video rendering.
3. Many apps are running in the background.
4. Constantly using your phone for a long time.
5. Running high CPU demanding apps.
6. Charging your phone up to 100%.
How can overheating damage our smartphone
Performance
Overheating can shorten the lifespan of a CPU. The temperature of a CPU is not as same as the body of a phone. Also, the CPU has different temperature handling capability. Overheating CPU can damage other components of phone as well.Especially when you are running heavy graphics intensive game or have many apps in the background can heat your CPU to a large extent. Continuously overheating your phone can make give permanent damage to your phone. You can experience poor performance because modern chipsets are build in a manner that when CPU is getting overheated, CPU slows down processing speed to cool down.
Battery
The best rechargeable batteries on the market are lithium-ion batteries. Powerful tech often comes with disadvantages, though. These batteries have two primary problems when it comes to overheating. The first is the era of lithium-ion batteries. In reality, even if not in use, they will degrade. Your battery will work well for a few years, but your smartphone will experience greater temperatures as it degrades.The second issue with lithium-ion batteries is that they are heat sensitive. If you are using your phone directly on the sunlight, you might unknowingly harm your phone. It speeds up the aging process whenever your battery is subjected to overheating. This is obvious when you start to realize that your battery charge does not last as long as it was before.
How to prevent your phone from Overheating
- Take some gaps while doing heavy or graphics-intensive tasks.
- Avoid using your phone directly on the sunlight.
- Uninstall unused apps.
- Close the apps that you are not using.
- Do not turn your screen brightness up
- Take your smartphone case off when the phone is getting heated up.
