AMS-02 provided the unprecedented statistics in the measurement of thepositron fraction from cosmic rays. That may offer a unique opportunity todistinguish the positron spectrum coming from various dark matter (DM)annihilation channels, if DM is the source of this positron excess. Therefore,we consider the scenario that the DM can annihilate into leptonic, quark, andmassive gauge boson channels simultaneously with floating branching ratios totest this hypothesis. We also study the impacts from MAX, MED, MIN, and DCdiffusion models as well as from isothermal, NFW, and Einasto DM densityprofiles on our results. We found two parameter regions that can satisfy bothAMS-02 $\frac{e^+}{e^++e^-}$ and $\bar{p}/p$ datasets at 95\% CL. i) Under theNFW-MIN combination with $M_{\chi}\subset[10,30]$ TeV. ii) Under the Einasto-DCcombination with $M_{\chi}\subset[500,1500]$ GeV.
