Apple watch unable to turn on after overnight charge.

I usually put my watch to charge every night before i go to sleep. But I am experiencing unexpected behaviors where the watch will get unusually hot the following morning and I can’t turn it on despite hard reset ( the screen stays black ).

The only solution is to leave the watch for few days to drain all it’s battery then recharge it back ( snake charging screen will appear ).

This issue is quite rare, it happens for about 1-2 times per month (sometime none). The thing I concern the most is the high temperature when it happened, which may damage the battery and the internal components.

Note that my charger is original and it works fine with my series 2.

About my watch : Series 5 Apple Watch Edition 44mm Titanium casing, bought in Japan. Never dropped or submerged into liquid before.
