User anh0l demonstrated running Windows 11 on Arm from a Xiaomi Poco X3 smartphone, which retains a split partition for Android and has a functioning UEFI. Users reported touchscreen control issues, particularly with inverted functionality on the right side, and temperature spikes reaching approximately 48 degrees Celsius (118 degrees Fahrenheit) during testing. Other Android smartphones have also experienced similar temperature levels. The Xiaomi Poco X3 can run Valve's retired Source engine at 30 FPS but struggles with Source 2-based Counter-Strike 2. Compatibility is better with Snapdragon 800 Series or newer CPUs, while older models are less effective. The shared architecture between Snapdragon CPUs in Windows Arm laptops and Android devices allows for this crossover, though driver support is incomplete. Despite high temperatures, anh0l claims the experience "runs flawlessly," with web browsing and basic Blender animations functioning smoothly at 120 Hz, impacting battery life and device temperature.
