Magnetophonon resonances induced by surface optical phonons are studied in both zero and nonzero dc current in n-doped graphene using the balance-equation scheme for nonlinear magnetotransport. At high temperature, obvious magnetophonon resonance in longitudinal resistivity can be observed. The observed single resonant peak at low mobility is composed of several main and minor peaks at high mobility. A novel peak position shift may be obtained for this system with nonequidistant Landau levels. For magnetophonon resonance in the presence of nonzero bias, the positions of resonant peaks shift and the oscillation becomes weak with an increase in drift velocity.
