The latest flagship from OnePlus is here and we’ve already compared the OnePlus 2 to the OnePlus One. Now it is time to pit the new “Flagship Killer” with one of the most powerful smartphones on the market and the first to come with 4GB of RAM – the Asus Zenfone 2 (ZE551ML).
The Zenfone 2 comes in many variants. In this comparison, we will be focusing on the ZE551ML in particular which is the 5.5″ model that itself is available in different storage, processor and RAM options. We have made the comparison as simple and easy to understand as possible. UPDATE – We now have a full in depth comparison between the two devices including a video. You can check it out here.
