I still haven't measured yet, but if it noticeable, it should be at least 10 to 20% (I can't remember but IIRC there's an empirical law about that)

My battery is now @60% of its maximum capacity so every milliWatt counts. I tuned my TLP to the lowest settings possible so to still have acceptable performance.
