iPlay60 Mini Pro auto shut down when playing videos on Youtube, Red Note, Tiktok etc

I bought an iPlay60 Mini Pro in Nov’24. Recently the tablet starts to auto shut down by itself when I run video apps like Youtube, Red Note, Tiktok etc. Sometimes it shuts down few seconds after I click on a video clip, sometimes it shut downs after couple of minutes, half way watching a video. I tried to turn off battery saver option but the sudden auto shut down still occurs. There are also times where I finish watching a 1.5 hrs video without any problem.

This auto shut down problem seems to happen randomly but quite often. Anyone encounter the same problem has a solution? Thank you in advance.

You still have warranty? I also have a 60 mini pro which is fully patched and runs just fine.
