From what I've heard in the past the Tekin brakes are passive. They don't apply power to the coils. It's simply a short across the coils similar to the brushed days.
A lot of brakes gets the motor hot, and when the motor's hot it runs less efficiently so you end up using more power to go the same speed. I think that's what drains the battery so much.
