got a new laptop, installed 18a. If I'm debugging, one of my cpu cores is constantly railing (i.e. task manager says matlab is using ~25% cpu) and it decreases battery life.
Also, sometimes matlab freezes, when I'm not looking at it, and I have to restart

It appears you have encountered this issue: Bug report 1736753 I suggest contacting support for possible workarounds and solutions. You may find that closing extra figure or MATLAB desktop windows makes the problem go away the next time you debug. Using breakpoints instead of dbstep may also help.

closing all figures and using breakpoints does not solve the problem. Will contact support, likely stick to 2017B

I've the same problem on Linux (MATLAB 2018a). The load of one core is about 80-90% at using breakpoint.
