| High Temperature in 5G | Network Modem Stress | Switch to LTE/4G temporarily |
What is the Android 15 Overheating Issue?
The Android 15 overheating issue typically refers to a sudden rise in device temperature following the installation of Google’s latest OS update. This phenomenon is often accompanied by the “Device temperature is high” system warning, which limits performance to protect hardware.
While some heat is normal during the initial setup phase, persistent thermal issues on Android 15 are usually linked to post-update background optimization. The system re-indexes files, optimizes apps for the new API 35 environment, and performs intensive media scanning.
If your phone stays hot for more than two days, it indicates a conflict between the system and specific apps or a bug in the thermal management driver. Android 15 introduces more aggressive thermal throttling, making users more aware of heat spikes than in previous versions.
Step-by-Step Solutions
1. Update All Apps to API 35
Many apps are not yet fully optimized for Android 15. These legacy apps can cause “zombie processes” that loop in the background, consuming CPU cycles and generating heat.
Open the **Google Play Store**, tap your profile icon, and select **Manage apps & device**. Ensure all pending updates are installed to resolve compatibility conflicts.
2. Clear Media Provider Cache
Android 15 performs a deep scan of your storage to update its library. If you have thousands of photos or videos, the Media Provider service can get stuck, causing the phone to run hot.
Go to **Settings > Apps > See all apps**. Tap the three dots in the corner and select **Show system**. Find **Media Provider**, tap **Storage & cache**, and select **Clear Cache**.
3. Manage Background Processes via ADB
If your phone remains hot, you can identify which process is hung using a computer and ADB. This helps pinpoint the exact service causing the thermal spike.
# Check top CPU consuming processes
adb shell top -m 10 -s cpu
# Force stop a specific rogue process (replace package.name)
adb shell am force-stop com.example.appname4. Reset Network Settings
Android 15 may struggle with specific 5G bands in certain regions during the early rollout phase. Constant signal searching generates significant heat in the modem area.
Navigate to **Settings > System > Reset options > Reset Wi-Fi, mobile & Bluetooth**. This flushes corrupted network configurations that might be forcing the modem to work at maximum power.
5. Disable “Smooth Display” Temporarily
Higher refresh rates (120Hz) require more GPU power. If your device is struggling with thermal management on Android 15, lowering the refresh rate can provide immediate relief.
Go to **Settings > Display** and toggle off **Smooth Display**. This limits the screen to 60Hz, significantly reducing the thermal load on the processor.
