Sorry to hear it's happening in the latest generation product too. This is really disgraceful by Dell as the issue has been known about for years and they don't seem to care. Same with the crappy thermal pasting job that their factory does.

Do not expect the issue to be fixed. People bought XPS's years ago thinking Dell would release a patch in some reasonable amount of time, but it never came.

If your use case involves a lot of time away from a charger, I would send it back. Maybe splurge a bit more for a Surface Book, assuming Microsoft cares a little more about putting out a well finished product.
