High CPU Usage
Skype for Business (Mac) is eating an enourmous amount of CPU at idle (17.8-50%+) and even more when in a call. I cannot deploy this to laptop users in my department as their fans stay on at all times. Please optimize. On a side note, thanks for the file transfer ability!

MacOS: 11.2.2 (20D80)
I can't see an option for logging, just a button "Collect all logs" under General.
I don't have any "personal" tab (Swedish version, and nothing translates to personal).
Second tab is Contacts, and under that there is only a "Use compact contact list".
Tried these 2 from the commenters below, and it dropped ... thanks Mike and Anonymous.
1. In Options | General | Logging in Skype for Business - choose Light.
2. I just got it to drop from 25-30% down to 0% by turning off "Show pictures of contacts"under settings / personal.
Pretty scary that this issue was created over 3 years ago and nothing has been done to resolve it. I've got a brand new macbook pro, and never had a computer battery drain as fast as with skype for business open. And that's without even using the app! I don't see how this is not just bad programming. How is microsoft left in the gutters by everyone else?

would the team review and comment on this is going to get better? i could use the laptop as a toaster .......and it makes good half-boiled eggs.

Literally unacceptable behaviour of a paid business app. I really believe that the issue should have been solved ages ago. But here we are. Please Microsoft solve it because people rely on this particular app for their work.
Has this issue been fixed already? If so what version, patch etc as I still have an issue and the fan on my Macbook Pro is running and the battery drain is enormous.
Yes. Me too. I notice that it is particularly a problem when I move around the building. It seems lavish (5-6%) when I first start it and haven't moved and I'm doing nothing. But when I move elsewhere in the building (close lid, walk to new room with probably different network access point, open lid) then it sometimes spins way up to 50-100 or more. I use SystemPal to track the CPU temperature. That helps alert me. Ridiculous this isn't fixed after so many votes and comments.

25-30% cpu usage? Hah. We've seen spikes like the above across our org for YEARS, especially during presentations. You'll just hear your fans take off like helicopters out of the blue. You've got to force quit when it gets this way. Additionally, we've noticed some of its buggy behaviour seems to correlate when you jump around on different nets/proxies/vpn. We do a lot of that in IT - especially when on outage calls.
We'd move away from it if weren't so integrated with outlook. Zoom seems to have the better/faster/cheaper trifecta - but we can't always use it due to security concerns. *sigh*
Come on guys, fix this already. SfB is singlehandedly draining all battery on my machine...
Just has a 1.5 hour video conference and my battery went from 100% to 40%. My MacBook Pro is 3 weeks old......
Sort it out Microsoft. This is shocking for business software people actually pay for....
In Options | General | Logging in Skype for Business - choose Light. Then the process dropped till 0,5%
Workaround; when you're not using it make sure you select 'Contacts' from the left menu pane. You'll see your CPU drop in a few seconds. When you switch back to e.g. 'Chats' it shoots up again. Totally unacceptable for such software but works for me to keep things calm.
This is a disgrace. Skype for Business has a process running in a background with constant 20-30% CPU usage, all the time, SINCE YEARS. If I kill the process, Skype keeps working fine. If I exit Skype normally, this process still stays and eats up the CPU power. I am about to write a service which kills this process automatically, because Microsoft seems to forget about this.
Version 16.27.37 on MacOS Mojave will regularly use 120–140% of the CPU on my Macbook Pro, kicking on the fan and draining the battery. This is with no windows open, and no active chats. The "Show emoticons in messages" option is unchecked.
For comparison, Slack uses 0.0 CPU when not in use.

People pay for this software. It should be much better.
just found this when experiencing this myself.
Tried unchecking the show emoji symbols in messages under Skype Settings and so far the CPU is down. I also unchecked the sync between calendar and so on now to see if that helps even further.

I'm having the same issue. Whenever the fan starts to spin loudly I go check the activity monitor and Skype is always 120-130 with everything else being single digits. Once I quit Skype the fans slow back down and of course the energy impact goes away.
This is a critical flaw. I can't do Skype calls with my office unless I'm plugged in, and even then the charge will still drain faster than the battery can charge.
I'm on a new 15" MacBook Pro purchase August 2019 with 32GB memory and 1TB SSD. There's no reason this shouldn't perform flawlessly.
I used Skype for business on a call today on MacOS. The battery went from 100% to 42% after 30 minutes of call, the laptop became uncomfortably hot.
Hi! Reporting from August 2019 here, Skype for Business still using all the CPU. What an absolute stain this software has been for so many years.
