Asus Zenfone laser is a good choice to purchase.
Battery life is satisfying me as compared to Lenovo 6000+
It has little heavy weight as compared to same range smartphones
If you have to charge it with another charger it is takeing quite long time
One problem I am facing it is that if you have a audio msg on wassp and u start it then total screen become black till the completion of that audio
Hope it will helpfull
