Anyone having any throttling issues in Windows 10 on their new XPS 9370?

After some digging, this solved my problem.  I will chalk it up to a bad update or driver.  Not experiencing any throttling issues even on battery power--

Download the tool ... you will need your XPS Service Tag and follow the on-screen instructions to do a complete factory reset and install of Windows 10.  You will LOSE ALL DATA doing this.

Good luck!

Hi captb3n,

Thanks for posting.  Apologies that your system is not performing as expected.

According to my research, there was a BIOS update that addresses the issue.  Have you installed 1.2.1 or later?

I am running BIOS 1.2.1

I forgot to mention that this only occurs when running on battery power.  I understand Windows 10 does its best to maximize battery life, but there are occasions where I prefer performance over battery life especially with such a capable laptop.  I also tried a complete wipe and fresh reinstall of Windows 10 using their tool.

Here is some additional information, which may be helpful.  The link suggests that Dell Power Manager may be a solution.

The battery manager shows a lot of great info as to the batteries status.  It also confirms the power mode is "balanced" despite having the battery slider in Windows 10 set to "best performance".  I vaguely recall there being a second Dell power mode before, is it possible that is gone with a recent Windows update?

I'm also seeing throttling when I unplug the AC adapter if that makes you feel any better. When I run NovaBench with and without AC adapter there is a ~30%-40% drop in the performance score.

Thanks for the reply.

Here's my thing:  All the reviews I have read and watched on the new XPS have given it nothing but praise, particularly on the performance.  How can be that my experience is nothing like what I have seen in the reviews?  Really frustrating.

I had a similar problem where the CPU on my i7-8550 was stuck at 390 MHz. It was really sluggish. I found this: https://www.reddit.com/r/Dell/comments/5uh6wo/fixing_your_dell_xps_cpu_stuck_at_minimum/?utm_content... where someone else had a similar problem. It seems that if the CPU overheats or the power supply is not recognized correctly the clocks are locked down at a lower speed. Disconnecting the battery will reset the system. It worked wonders for my system. 

The Killer Wireless is a seperate annoyance that still is an issue.
