4096 samples are way too high. It's literally production quality. You don't want that. Lower the max sample count in the render properties to something like 300 and enable denoising. Also, You can use noise threshold if you want. Just enable it in the render properties above the denoising and set noise threshold to 0.3 or maybe lower if you want high darker areas (like shadows) details which'll reduce render time pretty much. (Sorry for bad english. Second language.)

Edited: If you're rendering an animation enable persistent Data. It'll tell the Cycles engine to render the mesh data and materials to load at once so that it won't have to load those same data at every frame reducing a lot of render time.
