Battery drain issues post upgrading to Windows 11

Hi, I have got a Dell XPS laptop (16 GB RAM, 1 TB SSD, Intel(R) Core(TM) i7-9750H CPU @ 2.60GHz 2.59 GHz) and to my knowledge this has one of the better battery life (approx. 7-8 hours post charging)...

It's September 2022, and after 9 months of Windows 11 I have gone back to Windows 10. I have tried countless things to reduce the power usage on Windows 11, but nothing works. It simply uses much more power than Windows 10. The battery life on my Intel 8th gen CPU laptop on Windows 11 is 4 hours instead of 7 hours with Windows 10. That's 40% less, which is completely unacceptable.

Additionally, since I have BatteryBar installed, I can follow the power usage in every moment. I have noticed Windows 11 ramps up the power usage much more on every task, but the performance is even lower than on Windows 10. And then it takes 5-10 seconds to lower the power usage, whereas Windows 10 lowers the power usage instantly after the action has been performed.
There is something VERY wrong with how Windows 11 handles the CPU.

Hi splus9 I don't think going back to Windows 10 is an option. I am looking for Microsoft to fix this issue, because if this is not done then any powerful laptop you buy paying a huge amount will have the same problem 🙂

Thanks
