My oneplus 6 gets switched off automatically after power on. Once power on it runs for approximately 1-2 minutes then switches off. Battery is fully charged. Strange thing is when it is connected to laptop with usb cable, it does not get switch off.
I have tried resting it. Even complete factory reset. Tried by downgrading to android 9 also, still same issue. Not sure if it’s hardware of software issue.
One more thing is that it gets switched of even if connected to charger. Only if connected to laptop it works.
If anyone can help, please let know
