The factory reset is a separate procedure from draining the battery and fully charging.
Just doing a factory reset alone very well may fix the issue.
The factory reset is correcting whatever got messed up in the inital config of the phone that is using rediculous amounts of battery.
Draining the battery and charging to 100% may help calibrate the software/electronics to ensure maximum battery capacity is utilized...it may also do absolutely nothing but it cant hurt.
I dont think there is a right or wrong way to do this but when I was messing with it this is just what I happened to do:
Drained battery to 0.
Plugged phone back in.
Let phone charge all night.
Next day battery life was tenfold better.
