On mine (when it was working!
) the speed/power drops quite quickly from full, in the standard programme. Maybe from as high as 75%.I would like to reprogramme the speed drop. It is annoying because it will drop the 'speed 2' at the same time the high power in 'speed 3' is decreased.
I understand the power drops to protect the battery, but speed 2 power does not need to drop in proportion. It can be delayed.
