We study the average fidelity of the standard quantum teleportation when the quantum channel is subjected to different local independent noise environments frequently encountered in real quantum communication protocol. We show that only $$ \left|{\mathrm{Bell}}_1\right\rangle =\frac{1}{\sqrt{2}}\left(\left|00\right\rangle +\left|11\right\rangle \right) $$ is the best quantum channel in different independent noise environments, even in the depolaring noise environment. Our work can shed some light on the application of practical standard quantum teleportation protocol.
