Note8 Random Restarts when Idle

[aahd81]

I have searched all over the place for anything that works with no luck, so asking sharper minds.

My Note8 phone started restarting randomly if left idle. The deets:

Have tried settings, updates, safe mode, cache wipes, factory resets etc multiple times. Not better even without loading backed up data and apps.

A reboot is usually every 3-10 minutes

Reboots in full; functions properly when not restarting

Can stay on as long as there is battery unless lock screen is dismissed

Stays on connected to the laptop/charger.

I concluded this may be a faulty battery as I let it run dry a few times since upgrading to a newer Note.

BUT

If I let Audible (ebook reader) or YouTube run in the background. It is a continuous operation and the phone does not restart until the app is closed. (Phone restarts with or without Audible installed so the app does not seem to be the problem).

Does it seem like the battery to anyone else, with the apps functioning?

Or should I reflash Samsung stock ROM. Those seem like the only options to me. Anything?

Thanks for taking the time.

Tried flashing the official Samsung ROM again to see if it helped.
Odin: 3.14.1
ROM: Official N950FXXSCDTF1 (Australian)

As long as the phone was downloading updates after the flash, there were no resets. As soon as it went idle it rebooted within a couple of minutes.

Hi, have you solved the problem? Have you tried to change the battery?
