Why does the Xiaomi Pad Mini get hot when watching videos?

When you just get the pad/update the version/replace the device, the Xiaomi Pad Mini will compile the newly updated code. This process will consume system resources, accompanied by short-term power consumption and heating problems. This process will last for 1-2 days and is normal. After replacing the device, please update the software version. The software on the old pad is not compatible with the current Android underlying system. Please update the software or uninstall and reinstall it.
