Advanced analysis of pp collisions at $\sqrt{s}=7$ TeV collected by the photon spectrometer PHOS of the ALICE experiment
is presented. The 2010 dataset with integrated luminosity $L_{\rm int} = 7,7~\mbox{nb}^{-1}$ has been analysed. Improved energy and timing calibration allow to reconstruct the spectrum of inclusive neutral pions production at midrapidity in the transverse momentum range $0.8 < p_{\rm T}<25$ GeV/$c$. PHOS measurements are complemented by other alternative methods of $\pi^0$ reconstruction performed by ALICE. Precision measurement of the $\pi^0$ spectrum allows one to validate perturbative QCD calculations. Comparison of data and different model calculations are discussed.
