Your Xiaomi 15 Ultra is built for performance, but intense gaming sessions can sometimes push it too hard. When the phone overheats, you may notice frame drops, touch lag, dimmed brightness, or sudden game closures. This usually happens because the processor is under constant load, background activity is piling up, or certain settings are forcing the phone to run at full power for too long.
Why Your Xiaomi 15 Ultra Overheats While Gaming
- Graphics settings in games are set too high for long sessions.
- Background apps are consuming CPU, GPU, or RAM.
- Phone temperature rises due to charging while gaming.
- Poor ventilation or using a thick phone case traps heat.
- System and game optimizations are not properly configured.
1. Close Background Apps Before Gaming
Background apps continue running even while you are gaming. They compete for system resources and generate extra heat, which raises the phone’s overall temperature.
Open Settings, and then tap Apps.
Tap Running apps, and then close any apps you are not using before launching your game.
2. Lower In-Game Graphics Settings
High graphics settings push the GPU constantly, which generates heat fast. Reducing visual quality slightly can significantly lower temperatures without ruining gameplay.
Open the game, and then tap Settings.
Tap Graphics or Display settings, and then lower the resolution or frame rate option.
3. Avoid Gaming While Charging
Charging already creates heat, and gaming on top of that doubles the thermal load. This combination is one of the most common causes of overheating during play.
Unplug the charger, and then let the phone cool down.
Resume gaming only after the battery temperature returns to normal.
4. Remove the Phone Case During Long Sessions
Some cases trap heat and prevent it from escaping properly. Removing the case helps the phone cool faster, especially during extended gaming sessions.
Take off the phone case, and then place the device on a flat surface.
Avoid covering the back of the phone while gaming.
5. Enable Battery and Performance Optimization
Xiaomi includes system optimizations that balance performance and temperature. When disabled, the phone may push maximum power continuously, causing heat buildup.
Open Settings, and then tap Battery.
Tap Performance or Battery optimization, and then enable the recommended balance mode.
6. Restart the Phone Before Extended Gaming
Restarting clears cached processes and resets the CPU and GPU workload. This helps prevent accumulated heat from earlier usage.
Swipe down from the top of the screen, and then tap the Power icon.
Tap Restart, and then wait for the phone to boot before gaming.
Overheating during gaming does not always mean there is a hardware problem. In most cases, adjusting performance settings, reducing background activity, and improving airflow will keep your Xiaomi 15 Ultra running smoothly even during long play sessions.
FAQs
Is overheating while gaming normal on flagship phones?
Yes, to a certain extent. High-performance games push the processor and graphics chip, which naturally generates heat, especially during long sessions.
Can overheating damage my Xiaomi 15 Ultra?
Occasional heat spikes are normal, but repeated overheating can reduce battery lifespan over time. Managing temperature helps protect long-term performance.
Should I use a phone cooler or fan while gaming?
External coolers can help during extended gaming sessions. They are especially useful for demanding games that run at high frame rates.
