It's the Bluetooth Radio which is a part of Intel AX201 card.and I just wonder why it consumes so much battery power when the notebook get into modern standby sleep(10% in around 2.5 hours and even drain the battery to death).As i understand the bluetooth devices should be in sleep mode also when the notebook into sleep however it drains the battery power all the time.And if i disable the Bluetooth Radio and get the notebook into sleep mode then only 10%-12% each 24 hours will be consumed which is much reasonable.

Thanks for your assistance my friend.I didn't see the "power management" tab in AX201 properties.And i have tried below steps but none of them works.
1. Check Power Settings:
Ensure that power settings are optimized for energy efficiency. Go to Windows power settings and adjust the options for sleep mode.
2. Update Drivers:
Check the manufacturer's website for updates to the bluetooth drivers.
3. Disable USB Selective Suspend:
In some situations, USB Selective Suspend can interfere with Bluetooth operation during sleep mode. You can disable it in advanced power settings.

Unfortunately after upgrading the bluetooth driver to latest version 18.104.22.168 nothing changes :(

No matter check or uncheck this option it still drain the power when modern standby sleep.The only solution I can find is to shut down the Bluetooth adapter before sleep @Godisgracious1031

Intel said the battery power consumption is related to the Laptop's design and/or at an OS level. @Godisgracious1031
