Battery Drain of 5%/hour due to Audio Service classified as Activator being the offender

[TT93-_]

I just purchased a new HP Pavillion  14 EC0036AU that comes pre-installed with Windows 11 last week. Been on Mac OS for the past 8 years so please bear with me. I usually use my laptop in spurts with long gaps (8-15 hours) in between. I noticed two main issues with my laptop. My laptop was draining too much battery while in sleep mode, 14-15% to be precise in four hours until it automatically entered Hibernation mode after which the battery drain subsided or reduced. I searched online for possible causes and diagnosis and performed a sleepstudy  through the command prompt which indicated that my laptop was operating moderately even while on sleep due to some 'Audio Service' of 'Activator Type' for the entirety of the while it was in sleep till it reached hibernation. This Audio Service was the top offender. From my limited knowledge being of the 'Activator' type means it's a system software, can i modify it? My audio drivers are all up-to-date. Here are some photos :

As you can see the first 4 hour sleep cycle just consumed 2% batteryThe subsequent 2 sleep cycles consumed 14 and 15% respectivelyNo major offenders for the first sleep cycleNo major activator or other type causing significant drainDRIPS of the draining cycleList and type of offenders 

As you can see from the above photos, there were 3 major sleep cycles for the sleep study i performed. All ran for 4 hours till auto hibernation. In the first one only 2% battery was consumed while for the remaining two 14% and 15% were consumed. I do not know why this is happening. I have both alexa and cortana disabled as well. I would also like to ask if there is a way to reduce the time when my laptop enters hibernation from sleep when on battery.

Any help would be much appreciated.

Thanks in advance.
