How to Stop Your Phone From Overheating While Gaming
Phone getting hot during games? Learn why it happens, which settings reduce heat, and safe habits to prevent throttling and protect your battery.
It’s normal for phones to get warm while gaming. But if your phone becomes hot to the touch, dims the screen, or starts stuttering, it’s overheating. Heat hurts performance in the moment and wears out your battery over time. Here’s how to keep your phone cool.
Why phones overheat during games
- Demanding graphics push the processor and graphics chip hard.
- High frame rates mean the phone does more work every second.
- Charging while playing adds battery heat on top of processor heat.
- Thick cases trap heat.
- Warm environments — sunlight, cars, and beds — make everything worse.
When your phone gets too hot, it throttles, lowering performance to cool down. That’s why games often start smooth and get choppy.
Quick fixes you can do right now
1. Take off your case
Thick or rugged cases act like a jacket. Removing the case during long sessions can make a noticeable difference.
2. Lower graphics and frame rate
Drop from Ultra to Balanced graphics, and choose a lower frame rate. A steady 60 FPS that stays cool is better than 120 FPS that throttles to 40.
3. Don’t fast-charge while playing
Charging generates heat. If you need to charge, use a slower charger or let the phone charge before you play. Some phones offer a setting to power the phone directly from the charger during games, reducing battery heat.
4. Lower screen brightness
The display uses a lot of power and adds heat. Turn brightness down a few steps.
5. Play in a cool spot
Avoid direct sunlight, hot cars, and soft surfaces like beds and couches that block heat from escaping. Hard, cool surfaces are better.
Safety note: Never put your phone in a freezer or refrigerator to cool it down. Sudden temperature changes can cause condensation inside the phone and damage it. Let it cool naturally in the shade.
Settings that help
- Game mode or battery-saving game profile: Many phones let you choose a performance profile per game. Balanced or battery-saving profiles run cooler. See our game mode guide.
- Turn off Bluetooth, GPS, and mobile data if you’re not using them.
- Use Wi-Fi instead of 5G when possible; mobile data in weak signal areas can make the phone work harder and run warmer.
- Close background apps that use the camera, navigation, or video.
Accessories that help
- Phone coolers: Thermoelectric coolers can reduce temperature during long sessions. Read do phone coolers actually work?
- Thin, ventilated cases: If you need a case, choose a slimmer one.
- Controllers that hold the phone loosely: Some controllers leave the back of the phone open to air.
Warning signs to take seriously
Most heat during gaming is normal, but stop using the phone and let it cool if you notice:
- A warning message about temperature
- The phone shutting down by itself
- The battery or back panel bulging
- A burning smell
If your phone overheats even when you’re not gaming, or the battery swells, contact the manufacturer or a trusted repair shop.
How heat affects your battery
Lithium-ion batteries age faster when they’re hot, especially when they’re also full. Keeping your phone cool during long gaming sessions helps your battery keep its capacity for longer. Our guide to battery health for gamers explains more.
Cool gaming checklist
- ☐ Case off for long sessions
- ☐ Balanced graphics and a steady frame rate
- ☐ No fast charging while playing
- ☐ Lower brightness
- ☐ Play in a cool, shaded spot
- ☐ Use a cooler for marathon sessions
A cooler phone is a faster phone. Make these habits part of every long session, and you’ll get smoother games and a battery that lasts years longer.
