Secondly, It's not that Rinnegan draws less or more chakra, it's that Sasuke uses EMS a lot more apparently. He only really uses Rinnegan for Amenotejikara. The other six paths we barely see him use.

Thirdly, the tomoe indicate that his Mangekyou powers are present. It's not really a "full power" kind of thing, it's more that unlike overuse of Rinnegan powers which forces him to close his eye, overuse of Mangekyou power forcibly deactivates Mangekyou.
