You should be doing cardio regardless.
15% is when I cut down to 8-10%. There is no giant secret. Eat enough protein, eat 20% fat if you are natty, eat the rest carbs. Eat in a surplus so that you are making gains in the gym but not so much that you are putting on lots of fat. This should make you gain between 1/4 lb to 1 lb a week. Bulk as long as you can until you hit 15% bf, then cut.
Keep your protein as higher or slightly higher than before. Drop carbs by about 2/3. Keep fat where it is or drop it slightly near the end of the cut. Do the same workout and cardio you were doing during the bulk. If your diet stalls, do a high day or two where you up the carbs to maintenance or slightly above to give your body some glycogen and time to recover then back to the cut. Once you hit 8-10% then go back to your bulk. I like to ease the calories up over about a week.
Eat the same thing everyday. I give myself one cheat meal a week during my bulk, no cheat days in the cut. If I hit 15% during the winter and I’m making great progress, I might bulk a little longer. I try to make sure I end a cut during June or July so I look good at the lake all summer.
It’s really not hard. Even during a cut, you get used to the deficit in about a week.
