Wow super phone zuk z2 work good battery life good camera good multitasking good volte 4g speed good u-touch technology function very good super phone 5inch display wallpapers and screensaver awesome yes it can even last for 7hours, as a zuk z2 owner im really satisfied with the experience but if u prefer gaming on a larger device go for the mi max but if ur comfortable on a 5inch device you wont regret it because the performance is just amazing either in gaming or day to day usage.
