This happens sometimes when Wi-Fi keeps the phone’s radios active, even without apps running. Try forgetting the Wi-Fi network and reconnecting, disable background network scanning in Settings → Wi-Fi → Advanced, and check for any apps allowed to run in the background. If it persists, a factory reset often resolves hidden firmware issues causing heating.

This could happen due to an app probably working extra in the background, you can see what it could be if you go to Settings > Battery > Battery usage > Battery usage since last full charge.

Please check it and see if there is anything unusual with a higher battery usage.

I had the same issue with my ROG 9 Pro. It used to heat up even when I was not using it, as long as WiFi was on. In my case the problem was related to the room temperature. After I got my air conditioner repaired by AC Maintenance UAE, the device stopped heating. My suggestion is to check your AC cooling. Sometimes high room temperature causes the phone to heat even with no apps running. Getting the AC fixed helped me, so you can try that too.

Many ASUS ROG 9 Pro users have recently reported unusual heating issues even when the device is idle and only connected to Wi-Fi. The problem often appears without any active apps running in the background, and even with the latest firmware update installed. While diagnosing such issues, many users check their network usage or test stability by running lightweight online apps or games. During this process, some even explore options like car parking multiplayer to see whether the device heats up under minimal load or remains stable. This helps them determine whether the heating is caused by the Wi-Fi module, a background service, or a software conflict.
