As we have done the review of Zenfone 5 and Zenfone 6 both are worth of money and expectations may go high for Zenfone 4 too.


The Zenfone 4 looks exactly the younger brother of Zenfone 5 and Zenfone 6. It has the same poly carbonate back which gives you better grip.

In the lock screen it comes with big clock, weather, alarm in display and camera, messages and phone shortcuts to access directly. It can have up to nine home screens. The notification panel comes in Blue and White colour with an organized pattern. It has a crisp and clear display with low resolution screen. We were happy using the Asus keyboard as it is the same with Zenfone 5 and Zenfone 6 but little smaller, if you have thick fingers it is a little mess to operate. The Zenfone 4 comes with a lot of bloated apps like Omlet Chat, Amazon kindle and Mirror. Customization in power saver modes lets you to run battery last longer.

While video recording a Time Lapse mode is also available. It comes with by default camera resolution 2560×1440 (16:9) and which can be increased to 2560×1920 (4:3). We low the camera quality in low light and in sunlight as it takes sharp pictures. As the close up shots are good as there is not Flash in it. The rear camera can shoot video 1920×1200 Full HD which is a delight. We like the camera performance according to price it comes with.


We will compare Zenfone 4 with Motorola Moto E and Sony Xperia E1 dual with AnTuTu. Scores were 15,095 of Zenfone 4, 12,540 for Moto E and 13,198 points for Xperia E1. Graphics scores are 16.3 fps, 10.8 fps and 12.8 fps respectively for Zenfone 4, Moto E and Xperia E1. Last but not the least Quadrant scores of all the phones are 6,400, 5,233 and 5,110 respectively. So Zenfone 4 is a clearly better in terms of performance.
