The good news? You can fix and prevent phone overheating with the right strategies. Below, we’ll explore 14 highly effective ways to keep your phone cool while gaming. So you can enjoy longer, smoother gameplay without worrying about your device turning into a mini heater.

Why Does Your Phone Overheat While Gaming?
Understanding why your phone overheats is the first step in solving the problem. Your phone isn’t just randomly getting hot—there are specific reasons behind it.
1. High CPU and GPU Usage
Modern mobile games have stunning graphics, realistic physics, and complex mechanics, which all require a lot of processing power. When you launch a game, your phone’s CPU (processor) and GPU (graphics card) kick into high gear, working harder than usual to keep everything running smoothly.
The more demanding the game, the more power your phone needs. If the processor is constantly running at full capacity, it generates heat. Unlike gaming computers that have fans or liquid cooling systems, phones rely on passive cooling, which isn’t always enough for long gaming sessions.
2. Poor Heat Dissipation
Most phones are designed to dissipate heat naturally, but their small size makes it difficult. The heat generated by the processor and battery has nowhere to go, so it builds up inside the phone.
Some phone models handle heat better than others. Gaming phones, like the ASUS ROG Phone or RedMagic series, come with built-in cooling systems, while regular smartphones often struggle with extended gaming sessions. If your phone doesn’t have proper heat dissipation, it will start to overheat quickly.
3. Playing in a Warm Environment
Your surroundings play a huge role in how quickly your phone heats up. If you’re gaming in a hot room, in direct sunlight, or in a car without air conditioning, your phone will absorb that external heat, making overheating even worse.
Phones operate best at room temperature. If the air around your phone is already warm, it becomes harder for the device to cool down, leading to performance issues and potential long-term damage.
4. Too Many Background Apps Running
Even when you’re focused on your game, other apps might still be running in the background, consuming CPU power and draining your battery. Apps like social media, messaging services, GPS, and streaming platforms increase the workload on your phone, forcing it to work harder and generate more heat.
Some apps, like Facebook or YouTube, continue running even after you close them. The more apps your phone is managing while gaming, the faster it overheats.
5. Gaming While Charging
If you often play games while your phone is plugged in, this might be one of the biggest reasons for overheating. When your phone charges, it already generates heat. Add the strain of an intense gaming session, and your phone has to work twice as hard, leading to extreme heat buildup.
Fast chargers are especially problematic. While they power up your phone quickly, they also generate more heat than regular chargers. This combination of gaming and charging puts excessive strain on the processor and battery, leading to reduced battery lifespan and overheating.
6. Outdated Software or Game Bugs
Software bugs, glitches, and inefficient coding can also contribute to overheating. If your phone’s operating system (Android/iOS) or your favorite game hasn’t been updated in a while, it may be causing unnecessary stress on the CPU.
Developers regularly release updates to fix performance issues and optimize resource usage. If your phone or game isn’t running on the latest version, it might be wasting energy on inefficient processing, leading to increased heat.

How to Fix Phone Overheating While Gaming?
1. Lower Graphics Settings in the Game
Many mobile games have high-resolution textures, dynamic lighting, and complex physics. All of which require significant processing power. If your phone is struggling to keep up, the CPU and GPU will work overtime, generating excessive heat.
How to fix it:
- Open the game’s Settings menu.
- Locate the Graphics or Display options.
- Adjust these settings:
- Lower Graphics Quality to Medium or Low.
- Reduce Frame Rate from 60 FPS to 30 FPS.
- Disable unnecessary effects like motion blur, reflections, shadows, and anti-aliasing.
Reducing these settings lessens the workload on your phone’s processor, leading to less heat generation and better battery efficiency.
2. Close Background Apps Before Gaming
Many apps continue running in the background even when you’re not using them. Social media, email, GPS services, and messaging apps constantly sync data, using CPU power that could be reserved for gaming.
How to fix it:
- On Android: Open “Recent Apps” and swipe away everything except your game.
- On iPhone: Swipe up from the bottom (or double-tap the home button) and close unused apps.
- Use “Do Not Disturb” mode to block notifications that might force background processes to wake up.
Fewer background apps mean less strain on your CPU and RAM, reducing heat buildup.
3. Avoid Playing While Charging
Gaming while charging is one of the fastest ways to overheat your phone. Charging already generates heat, and adding the heavy workload of gaming doubles the heat output.
How to fix it:

- If playing on a desk, place your phone on a laptop cooling pad.
- Use a small desk fan aimed at your phone.
Active cooling accessories pull heat away from your phone, keeping it from reaching dangerous temperatures.

5. Remove Your Phone Case While Gaming
Thick phone cases trap heat, preventing your phone from cooling down naturally. Rubber, leather, or silicone cases are particularly bad at heat dissipation.
How to fix it:
- Remove the case before gaming.
- Use a ventilated gaming case that allows for heat dissipation.
- If you prefer to keep a case on, choose a thin, heat-resistant case designed for gaming.
Allowing airflow around your phone helps it release heat more efficiently.
6. Play in a Cool Environment
Your surroundings play a big role in how fast your phone heats up. Gaming in a hot room, under direct sunlight, or in a poorly ventilated space will cause your phone to overheat much faster.
How to fix it:
