Need help building custom kernel

I want to compile a custom kernel for my laptop running Manjaro so the battery lasts longer and there is no unneeded things in the kernel. The laptop has a Core 2 Duo and Intel graphics. If anyone knows of any guides that can help me with this that would be great!


I also have another question, if Manjaro pushes a new kernel through, will I have to recompile again using the new kernel?
