Windows 10: My Windows 10 CPU Utilization% stuck on 15% while laptop is running on battery instead of...

Dear Microsoft support,


My Windows 10 run smoothly on AC adapter, thanks to your OS algorithm & management..


However when I run my windows when laptop is on battery, then Windows CPU utilization% stuck on 15% max as per Windows Task Manager Performance tab.

Also, at that time, I face too much delay in any task open Excel/Word or IE or running any media/image editing softwares, any task consuming 8~10% CPU , while same softwares run smoothly without any delay when laptop is connected on AC adapter.

This CPU utilization 15% threshold issue is causing drastic performance impact for my laptop.


Please let me know why such issue is occurring now and how I can fix this issue of CPU utilization%.

:)
