Samsung Galaxy Tab S 10.5 Randomly Restarts

I have a Samsung Galaxy Tab S 10.5, running Android 6.0.1. It will randomly restart itself, and it seems that the problem is getting more frequent. It does not matter what application(s) I am using. Sometimes I am using my e-reader and haven't touched the screen in a minute or two; other times it happens at the basketball arena where I only check the basketball stats via Chrome during time outs. There doesn't seem to be a single application causing this. It seems to happen most often when I am riding the train to work (and no wi-fi in use), it also happens at the basketball arena (when connected to the wi-fi at the arena), but it only rarely happens during more intense usage at home (using wi-fi).

Please advise on how to diagnose this problem. Thank you.

Try replacing your battery. After three years, it's most likely shot.

I had this same problem, too, with a 2 year old tableT and tried everything on the internet I could find.
Thinking it was a battery problem, I took it to a local we-fix-it place and that was not it.

Eventually went through Samsung to get it fixed (out of warranty, $218 max on fixing it.)
Shipped it to them (price included). They returned it "fixed" saying it was a loose battery cable. It was not as the "reboot" happened right out of the box.

Now that it was "fixed", it was under a warranty. Promptly called them, sent back, included a detailed note not to "trust their quality control team as the reboot problem could go along time and not happen and need, sometimes, to run a few programs to see it happen."

Finally returned fixed. Notes state they had replace the motherboard. (what it actually said was "SVC PBA-PBA MAIN (XAR); SM-T800,-,SVC,M32").

So this is a motherboard problem according to my repair and issue. Guess it was cheaper than buying a new tablet. And I do like the Tab S 10.5. So glad I did it.
