When I have serial plotter open in the Arduino IDE with serial communication going on, the fans of my PC go full speed. On checking I found that Java(TM) Platform SE binary(32 bit) is using about 29% of the CPU.
This gives a big blow to the PC's battery back-up. Is there some way to reduce the CPU usage ?
The IDE version I use is Arduino 1.8.4
