How can we make Microsoft Teams better?

Teams using a lot of CPU

For some reason the latest update has Teams using between 8% and 25% CPU idling, doing nothing. There is an issue with this update.

    I’m impressed, I must say. Genuinely rarely can i encounter a blog that’s both educative and entertaining, and without a doubt, you have hit the nail on the head. Your concept is outstanding; the issue is something that too little individuals are speaking intelligently about.

    Surface Laptop 3, battery lasts maybe 2 hours in Teams video conference. Zoom video consumes much less.

    This is still applicable, adding some comments below to share our insights

    Initially when starting the Teams client it consumes approx 1.4 GB of memory (of 16GB in total) and 20-25% percent of the processor (Intel Core i5-8365U @ 1.60GHz).
    After it has loaded all components it free's up some memory and ends up around 1 GB consumed and when idling 1-10% percent of CPU consumed.

    General feeling is that the client is very slow and not performance optimized, this needs to be improved when comparing with other similar type of clients or the older Skype client even though it's not a fair comparison.

    Also keep in mind that the Teams client most likely would be great to utilize in a shared VDI or Citrix/TS environment but when consuming this amount of capacity it's not meant to be there

    If you have low battery try Microsoft Surface pro 6. New for this year are Intel’s latest eighth-generation Core i5 and i7 chips, both of which are faster and more efficient than their predecessors. Battery life has improved significantly. The Core i7 variant of the Surface Pro 5 only lasted six hours 40 minutes between charges. The Core i5 version as tested lasted nine hours, which is long enough to go out for day’s work without having to pack the charger.

    When I turn on video it is worse. When I turn off video it gets better.

    I am having similar issue on multiple devices Surface Pro 7 and Surface laptop 3 battery life seems to have drastically reduced.

    Using windows 10 1909

    I have provided energy reports and battery reports to Microsoft but they have said they cant see any issue with the them but the power consumption is still very high.

    Hi, I have noticed that my MS Teams uses a lot of CPU during conf calls - both the CPU and GPU are used during calls on quite high level for such "low resource" tasks. This makes my laptop generate heat as well as use a lot of battery.
    Usage goes much much higher if camera is used, but both camera and voice only with screen sharing is quite high usage compared to other similar software used.
    I tested this on both Intel and AMD Ryzen laptop and it is exactly the same

    Online meetings through the application drains the battery by about 20% per half hour on my 2018 Macbook Pro, regardless of whether the webcam is on or if I'm sharing the screen.

    Streaming videos would take significantly longer to drain the battery by the same amount.

    Keeping the application open for chats or document editing does not have as much of an impact on battery drain.

    MS Teams often uses 150% cpu on the leptop. (intel core i7 8th gen) The fan is leading to bad voice qulity. This happens with no other communication application (hangouts, slack...).

    If my boss would not require me to use it, I would not have it.

    I'm on Ubuntu 18.04. With teams running I had 80% battery and < 3 hr estimate. After disabling GPU acceleration in the main Teams settings page and restarting, I'm now up over 6 hr.

    A colleague saw the same behavior on Mac. Worth a shot if you're seeing this issue.

    I agree, CPU usage is an issue - especially on laptops and notebooks which have to run on battery.

  • Jakub Blažej commented  ·   ·  Flag as inappropriate

    the teams desktop client starts using 24% cpu (of quad core) a few minutes after startup if I dont open the app's window. I.e. when it launches automatically on startup in the background.
    After opening teams from notification area, the cpu usage stops.

    technical:
    I have created a stack trace using process explorer
    the issue seems to be a loop somewhere in stackframe on line 8, as everithing below it was the same on multiple smapshots.
    the last common frame after opening the window is on line 31.
