Macbook air m2 battery draining while on sleep

so it all started once I received my laptop from the service center after a display and motherboard replacement . I noticed that the battery was going from 100% to 0 % in 36 hours while on sleep mode they way generally people do close the lid , I had a talk with the apple support even after about 2 months of taking screen shouts , removing and reinstalling os , not able to use my device, capturing logs at least for 7-10 times still haven't received any solution . coincidently all the issues in this Macbook started occurring just after the warranty got over I feel everybody know how apple has priced there spare parts and repairs I mean one can get a new laptop for the price of a screen and a keyboard .
