In this paper, we investigate the dynamics of the neutral and charged test particles together with the radiation properties of an accretion disk around the charged hairy black hole. Firstly, we briefly overview the spacetime of the charged hairy BH and explore the horizon structure. Then we study the effect of the spacetime parameters on the motion of massive neutral and charged particles. Finally, we explore the radiation properties of the charged hairy BH using the Novikov–Thorne model. The important quantities are analyzed: the flux of electromagnetic radiation, the temperature of the accretion disk, and the differential luminosity. The parameters 
and l are found to decrease the flux of electromagnetic radiation, while the BH charge Q increases it. Similarly, the disk temperature and differential luminosity decrease owing to the impact of the and l parameters, and increase due to the BH charge Q.
