What is the Android 15 Overheating Warning?
The Android 15 overheating warning is a built-in safety mechanism that triggers when the internal hardware temperature exceeds safe operating limits. Unlike previous versions, Android 15 features more aggressive thermal management to protect the battery and processor from long-term damage.
When the device gets too warm, the OS may automatically dim the screen, throttle CPU performance, or disable certain features like the camera flash and 5G connectivity. If you see this warning, it means the system is taking active steps to cool down the hardware.
Step-by-Step Solutions
1. Identify and Restrict Power-Hungry Apps
Android 15 introduces enhanced “Battery Usage” stats. Navigate to **Settings > Battery > Battery Usage** to see which apps are consuming the most energy. If an app is using a disproportionate amount of battery in the background, it is likely causing the heat.
Tap on the app and select “Restricted” to prevent it from running high-intensity tasks when not in use.
2. Reset System Cache via ADB
Sometimes, legacy data from Android 14 can cause “ghost processes” that heat up the CPU. You can clear temporary battery stats and reset background processes using the following ADB command:
adb shell cmd package bg-dexopt-jobThis command forces the system to run background optimization, which can resolve temperature spikes caused by unoptimized app code post-update.
3. Disable “Adaptive Connectivity”
Android 15 frequently switches between 5G and Wi-Fi to maintain the best signal. This constant radio switching generates significant heat, especially in areas with poor reception.
Go to **Settings > Network & internet > Adaptive connectivity** and toggle it off. This forces the modem to remain stable, reducing thermal output.
4. Check for Google Play System Updates
Often, the main OS update is finished, but the underlying system components are outdated. These components manage the hardware-software interface.
Go to **Settings > Security & privacy > System & updates > Google Play system update**. Download and install any pending patches, as these often contain thermal driver fixes.
5. Use Safe Mode to Isolate Third-Party Issues
If your phone continues to get warm, boot into Safe Mode by holding the Power button and long-pressing “Restart.” If the phone stays cool in Safe Mode, a third-party app is the culprit.
Uninstall recently downloaded apps one by one until the temperature stabilizes.
