I am using macbook pro 2015 with Monterey version 12.1. Almost every time when I open the screen and login in the usage of cpu surges more then 200%. It's even stranger because mac isn't connected to any device! To fix it I turn off and on the bluetooth, which doesn't seem a good solution to me. Is there any better ways to fix it?
One of the suggestions was to turn off bluetooth and then back on. While doing so, two old devices were listed, one of them said the connection was "rejected." Before turning off bluetooth, I removed both of those devices, effectively clearing the device list. Upon removing both, the CPU usage immediately dropped from 216% to 0% fixing the issue for me. I never turned off bluetooth and after 3 hours and one restart, the issue has not reappeared for me. Hope this helps someone!
I have this issue too since updating to macOS 12.1. My machine is 13" MacBook Pro with Retina Display (Early 2015). Disabling bluetooth is just a temporary fix. I have recently reinstalling the OS, the issue persists.
Of course it's not normal, and normal is what was happening all those years. With the exception of that Bluetooth update back in 2015 that caused system notifications sound as 200% volume white noise outbursts scaring us to death.
Same situation here. MBP 15" Mid-2015, Monterey 12.1. High CPU use from bluetoothd, which disappears if I turn bluetooth off. Seems to be when coming out of sleep from the lid being closed. I've reported it via the link given on page 1.
The "fix" I posted about on 1/22 seemed to work for 5 days then the 200% bluetoothd process cpu usage returned. I installed the 11.2 update and hopefully that will fix this bug. (Mid 2015 MacBook Pro 15" BCM_20703A1 Bluetooth chipset)
I want to add that I was able to use my Magic Trackpad with Bluetooth off on MacBook Pro. Turning BT on/off made it actually disconnect.
A week later - I'm no longer seeing bluetoothd peaking at 200%, but now I'm getting kernel_task go to 500% when connected to external display (https://discussions.apple.com/thread/251715169)
Very messy by Apple :(
Thanks, shott85, this sounded interesting. I disabled the two options in the preferences. But after two days high CPU usage of bluetoothd reappeared just like before. So unfortunately, this approach does not solve the issue, at least not for me.
I experimented by connecting an external monitor and bluetooth mouse I am using throughout the day and got some change in CPU usage. But I need to test more to find out what is affecting the problem with bluetooth. It is difficult to test because it is a rare problem and will take days or weeks to learn more. I will report back in case there are any updates.
I also have the same problem with MacBook Pro 2015 and macOS Monterey V 12.2.1.
A fix should be created for this as soon as possible,
because the only way to reset the CPU load to normal is to turn the MacBook off and on again.

Same here - I just submitted a bug report to Apple with a link to this discussion. MacBook Pro 11.5, one week on a clean SSD with a fresh install of Monterey (12.2.1) (not an upgrade from prior OS - I installed to a blank SSD).
It doesn't help the problem still appears!
I have the same issue
Same problem here! I have a 2015 MacBook Pro 13", Monterey 12.1.
Most of the times I have no bluetooth devices connected, so it has to be something "internal".
In my case it doesn't solve the problem. After logging in cpu usage for bluetooth increases more then 200% just as before.
I'm experiencing the same issue daily on the same MBP type. I just submitted feedback on this per the advice from tree_frog.
exactly the same issue for me as well. Macbook Air - Early 2015 and macOS Monterey 12.1.
had no Bluetooth issues in Big Sur and Catalina .
am trying this... lets see if it works out.
bluetoothd high cpu usage
