Is this common for a brushless motor controller?

Of course power is important. But given a specific power, battery capacity and efficiency determine run time. And run time is everything in powerful cordless tools that suck current.

Go to DeWalt's website and look at their new brushless motor powered drills. The first three listed qualities tout efficiency and run time.

Product Features

DEWALT-built high power, high efficiency brushless motor--650 unit watts out (UWO) max power for superior drilling & fastening applications performance--delivers up to 57% more run time over brushed

XR Li-Ion batteries with fuel gauge provide 33% more capacity over standard packs

YouTube videos that test cordless drills usually compare the amount of work they can do on a single battery charge. Again, it's about efficiency.

Wrong. Weight is far more important than run time, particularly at the upper end (though DeWalt is certainly not even near "upper end"). Again, it's a balance based on the target market. Run time isn't even in there, though.

Why? DeWalt is crap. Has been for years.

It's a metric that no one cares about. There is a reason DeWalt has been a bottom feeder for years. I bought several of their tools a few years ago. The only one I still use is the circular saw but not often.
