I have reviewed lenovo vibe p1 it has amazing batteey life for sure but lenovo mobile manufacture have a great issue in combination of hardware with software, I mean to say that if they give better software they lack in hardware and vice versa, we have two huge examples of this as lenovo k3 note and now vibe p1 both these phones have very good specs but these both lack in performance, camera and gaming.So at end I would like to make a conclusion that if you are not a camera person and heavy gamer and use your smartphone for normal use like web browsing chatting and huge phone calls then its a very good phone for you.And also there are sone minor lags in the ui, surely needs to make some huge changes in its software department
