The Chinese Smartphone manufacturer Xiaomi launched the Mi4i in April 2015 at an even in New Delhi.  The smartphone is targeted at mid-range budget-conscious buyers looking something extra from the device without breaking the bank.

The Asus Zenphone 2 made by the Taiwanese conglomerate is the successor to the hugely successful Asus Zenphone 5. There are various models available for the Zenphone 2 we will compare the Rs. 14,999 model(Asus Zenfone 2 ZE551ML) with Full HD display and 2 GB RAM with the Mi4i.

The camera is at the back, on the top right corner along with MI logo above the speaker grill. The smartphone is quite thin measuring only 7.8 mm; considering the large battery size, this is a great feat by Xiaomi.

Asus Zenphone 2 (ZE551ML) – The smartphone looks premium with dark silver grey color.  The design is a bit inspired by the LG G3 with the power button at the back, which is difficult to reach.  The smartphone has a polyplastic body, and the rear has the Intel logo along with Zenphone printed above the speaker grill.

The smartphone is quite thick to my liking, it measures 10.9 mm vs the 7.8 mm thickness of the Xiaomi Mi4i.

It is quite bulky weighing 170 grams, which is also slightly higher than what we expect from a 5.5-inch smartphone. Otherwise, smartphone is robustly built and looks premium with metallic shine and finish.

The Zen UI is good but does come with some bloated APPs.

The Xiaomi Mi4i also runs on Android Lollipop 5.0 with MIUI 6.0 which is much evolved compared to the earlier versions of MIUI. The custom ICONS and themes look good and make it look much different than the stock android.  First-time users may find it difficult to find settings and options in the UI. However, I liked the UI and lots of customization options it provides to the users.
