High Power Usage since November 2019 Power BI Desktop Update very SLOW!

[THEG72]

Hi Community, The last couple of updates have made Power BI desktop extremely slow.

I have a surface Book2 and its consistently throttling the fan speed and putting a load on power?

Has anyone else seen this strange behaviour or know any fixes or things to try?

Even my small models are extremely sluggish when navigating visuals and the desktop is really not useable in this released version. A was a lot better last month.. ?

Are there any tips for improving this..here is the task manager screenshot

November Power BI desktop sucking my power up 😞

Hi @THEG72 ,

Did this issue appear on all of your pbix files? I'd like to suggest you create a simple pbix file without large amount of records and complex Dax calculation formulas to confirm this scenario.

@v-shex-msft  appreciate your feedback. If there is no load (ie small file) in the model there is no problem.

It was working fine with previous months update. So looks like i will revert back and try next months version and wait for next update.

Thanks again for you help.!

Hi @THEG72 ,

It sounds like power bi team changes the logic of internal formulas calculation and causes the 'high power usage' issues.
In my opinion, I'd like to suggest you can contact to power bi team to report this scenario. (notice: you can attach your device information to help them to confirm if this is a common or specific device optimization issues)

Thanks for your reply @v-shex-msft  

There definitely seems to be an issue with power usage on my surface book 2 only.

All models seem to perform fine on other pc's.

I guess I will log with Microsoft, the fan speed increases on the Surface Book, Task Manager shows power bi desktop is using Very High power and power bi desktop is not responsive doing basic tasks like changing font sizes or removing columns etc.

I am having the same exact issue since about November. Even in very small, simple files, changing formatting options and just selecting visuals results in multiple seconds of pause in most cases.

This is pretty hilarious considering that I'm running about 128GB of RAM and a 12-core processor at about 3 Ghz. My colleagues with similar setups are also complaining. I'll also submit a support ticket and include my system info there.

Load up the Windows Task Manager and check the Power Usage and Power Trend Usage on the Power BI Desktop application. 

I have found it is an issue with the Surface Book 2 and the November 2019 update. Prior versions didn't have a problem.

Has anyone else found a solution for the Surface Book and Power BI desktop power throttling issue?

What does your power usage say? it's not listed in the screenshot you took.

Also, I had both the Windows Store App and desktop versions of Power BI desktop installed on Windows 10 surface book.

I uninstalled all versions of power bi desktop and did a windows 10 update to get some updates.

Will reboot and reinstall and test both the App from the Windows Store and then test the direct download of exe file too.
