SivaprasathCM hi siva, the device is under warranty. it can be repaired or replaced at apple service center. do call apple toll free first bro. let them do some diagnosis and register a support case id. once lockdown is over you will be able to take it to service center.
mean while you can try to charge it for entire night. dont keep it right next to your bed. keep it in some table and observe after an hour whether any heat is produced while charging. even if no indication of charging its important to monitor that. also how is earth or neutral connectivity in the building? everything perfect?
