Dell India — Heating of laptop newly bought

Address: Pradhikaran Pune

Have recently purchased Inspiron 5406 2n1on March 10th 2021.
Service Tag : HXNV863, Express Service Code:[protected]

The laptop heats up and is very very hot to touch - is this normal?
I have referred this unit twice within a fortnight of buying for other startup issues. And had reported the heating too. The agency kept it for a 3 days for monitoring and returned it saying Dell has checked and corrected the problem.
I am concerned with the temperature of the laptop and the battery life which barely goes beyond 3.5 hours although the unit is new.
