JetBrains Rider is a cross-platform .NET IDE based on the IntelliJ platform and ReSharper.

It's been years since I've used Resharper and maybe things have changed, but if you are looking to improve battery life, it's one of the last things I would start using.

I use Rider daily on an M1 and easily get through the day. I'm not compiling every second, but using it pretty consistently along with slack/chrome/etc.
