Hi Krzysztof,

According to Meizu, they do have this hardware design to turn off
the device when battery temperature over 60 Celsius for the
protection.

And about the bug #1469369. It was updated with comments about the
fixes which was landed. Please feel free to comment in the bug for
the issue you have. We may need separate bugs to track different use
cases such as using youtube.

BR.
