IntelliJ also has a "Power Save" mode if you want to disable a lot of the background stuff while on battery. The reality is, with large projects there is a lot of crunching going on in the background. Laptops tend to reduce their processing power when on battery, so a few options are: - use a dev server! I have a desktop at home I can use - a cheap desktop is much better than a cheap laptop. Or rent an on-demand from the cloud. IntelliJ has nice remote development support. - plug into the wall - turn off everything non-essential like plugins - use emacs/vim! I love vim as much as anybody but now that I am older I don't have much time to mess around with configurations. I am learning rust and it is great to open up CLion and just get down to business.
