I am using Dawlance Inspire Plus Inveterer 1.5 Ton as well and it never goes above 6.2 amps at the starting. Didn't check after hours..
Bro what about your electric bill?
Here is my AC usage:
Room Size: 204 Sq Feet (No Direct Sun Light).
Timing: 9:00 PM to 8:00 AM (including 2 Hour Load Shedding )
AMP At Starting (6.2 or 6.3)
Waiting for this month electric bill.
