Hi Debosmita Das,
You might want to check powersetings & battery report
open an elevated commandline & run
powercfg /energy
(best to not do anything alse during the 60 seconds, it would impact the report)
The resulting report will give you a detailed html showing what's impacting your powerusage.
you can also run
powercfg /sleepstudy
This will generate a very detailed report of the last couple of days
Hope this helps,
