Processor and RAM

All the three smartphones pack different SoC (System on Chip) to keep themselves distinct in the competition. Mi 4i packs a SnapDragon 615 2nd generation SoC and ZenFone 2 packs an Intel Atom Z3560 SoC while Sony Xperia C4 Dual is powered by a MediaTek MT6752 SoC (visible in Lenovo A7000 and Meizu M1 Note).

All the three back the processor with a 2GB DDR3 RAM stick.


All the three smartphones run on Android 5.0 Lollipop overlaid with their home-made user interface. Xiaomi Mi 4i runs on MIUI, ZenFone on ZenUI and Xperia packs Sony's TouchWiz UI.


All the three pack identical 13mp rear camera with LED flash and a 5mp front camera. We tested both camera modules of ZenFone 2 and Mi 4i and was left quite impressive by their performances.

Battery and Storage

Xiaomi Mi 4i packs a 3,120mAh battery while ZenFone 2 comes powered by a 3,000mAh battery, which is non-removable. In comparison, Xperia C4 Dual packs a comparatively weaker 2,600mAh battery.

On the storage segment, Mi 4i, ZenFone 2 and Xperia C4 Dual feature 16GB in-built storage. But Sony is a step ahead by featuring memory expandability up to 128GB compared to ASUS's 32GB memory expandability support. Xiaomi Mi 4i sacrifices the expandable support.

Pricing and Availability

Xiaomi and ASUS ties in the price point, too, by offering Mi 4i and ZenFone 2 ZE550ML for ₹12,999. Both the smartphones are currently available exclusively on Flipkart.

Sony will release the price details of Xperia C4 Dual by June, but going by the configuration of the device, we guess it should be available under ₹15,000.

Our Say

Both Xiaomi Mi 4i and ASUS ZenFone 2 ZE550ML offer decent all-round performances. The hardware combination of Xperia C4 Dual also vouches that the smartphone will provide a great performance.

Though both ASUS and Sony offer 5.5 display, the Xperia device is much slimmer than the ZenFone 2 model. However, the weaker battery of Xperia is a letdown.
