1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsIf your Android phone slows down or gets uncomfortably hot during games, start with reversible fixes: restart it, install available updates, check free storage, and reduce the game’s graphics or frame-rate settings if those controls are available. Heat can trigger protective behavior—including reduced performance—so give the phone a chance to cool rather than trying to override its safeguards. Android settings and temperature features vary by manufacturer and model.
First, work out whether heat or another issue is causing the slowdown
Notice when the problem begins. Lag that appears immediately may have a different cause from slowdown that develops during a longer session. Also note whether the phone displays a temperature warning or changes its charging, connectivity, or power behavior. Those can be protective responses; touch alone is not a reliable way to diagnose a component or measure the phone’s internal temperature.

Google says a hot Pixel may reduce CPU performance, slow charging, limit connectivity, enter low-power mode, or shut down to protect itself. Other Android makers may use different safeguards. If you have a Pixel 6 or later, the Device Health and Support app can provide phone-temperature information; available features can vary by model and software release. Google’s Pixel support page explains how to get help and use the app.

Try these low-risk performance checks
- Restart the phone. This is a simple first check for temporary software trouble.
- Install available updates. Check for Android system updates and updates for the game. The exact update menus differ by manufacturer.
- Check available storage. Google says an Android phone can start having issues when less than 10% of its storage is free. This is general slow-device guidance, not a gaming benchmark or a guaranteed cutoff for every model. Google’s slow-device troubleshooting guide covers storage and other basic checks.
- Investigate recent apps if the problem started after installing one. Google recommends using Safe mode and removing recent apps one at a time to help isolate a slow-device problem. Follow the instructions for your phone, since the steps vary.
Lower the workload while you play
Adjust the game’s graphics or frame rate
If the game has graphics-quality or frame-rate controls, try a less demanding setting. Compare how the same game feels on the same phone under similar conditions. This is a practical troubleshooting step, not a guaranteed fix: Google’s support pages do not promise a specific frame-rate increase or temperature reduction from changing game settings.

Reduce screen and background activity
Lower screen brightness and stop apps or features that are using substantial phone resources. Google recommends reducing brightness and resource-heavy use to help manage heat. You can also avoid combining a demanding game with video recording, streaming, hotspot use, or charging where possible; Google lists these activities among potential causes of a Pixel becoming warm.
Battery Saver may reduce background activity and some visual effects or features, but it can also delay apps or connections. It is not a guaranteed gaming-performance mode. For general battery guidance and feature caveats, see Google’s Android battery advice.

What to do if the phone gets too hot
Keep it out of direct sunlight, hot vehicles, and enclosed or poorly ventilated places. If the phone becomes too hot, disconnect it from power if it is plugged in, move it somewhere cooler, and leave it unused until it has cooled. Google gives that guidance specifically for Pixel phones; check your manufacturer’s instructions for your model. Do not continue playing through a heat warning or try to defeat thermal safeguards.

When to contact the phone maker
If basic checks do not resolve recurring slowdown or heat warnings, consult the phone manufacturer’s current support instructions or your carrier. Menus, diagnostics, and thermal behavior differ by model, Android version, region, and software update. Google also directs Android users to the device maker for model-specific help when general troubleshooting does not fix a slow phone. If the phone repeatedly restarts or crashes, use the manufacturer’s troubleshooting guidance for that symptom rather than treating it only as a gaming issue.
The cited official guidance explains troubleshooting and safety steps, but does not establish a measured FPS gain or temperature drop for any of these changes. Treat them as safe ways to narrow down the cause and reduce avoidable workload, not as guaranteed performance improvements.
