[HELP] Nexus 6p with latest android version random shutdown, cannot turn on or charing...

My 6p has been through random shut down twice since the latest OS update. And today is my nightmare. :'(

I unlocked the phone with fingerprint and go to app menu, the screen just frizzed, after few seconds I decide to reboot the phone long pressing the power button, I got a peek at the battery level, it shows 86%, so clearly it is not a power issue. However, I haven't even unlocked the phone, it restart automatically, and stuck on android logo animation.

After this, it goes dark totally, I'm now plug the phone with power outlet it doesnt even show its charging...

Anyone has same issue?
