Quick Review of Asus Zenfone 3

Display is made with more special addition of Super IPS+ technology. The full HD in a 5.2 inches screen is another advantage that enhances the sharpness, brightness and clarity of the screen display. The Gorilla glass 3 protection, at last makes it perfect.

The CPU Snapdragon 625 and GPU Adreno 506 are good hardware companions for mid-level performance. The 3GB RAM is enough for multitasking and games using more memory. We can expect smooth operation and user interface with this level of RAM

The rear camera is very high level with many features to enhance the quality. But after all of this good specs, Asus shocked us with a 2600mAh battery. Even with severe power optimizations by Asus, I don’t know how much this battery is reliable on heavy and long use?
