Performance, Benchmarks, Browser & Gaming

This is the segment where Zenfone 2 dominated consistently over all of our tests. We zipped through Multitasking like opening more than 15-20 apps and games at once, and everything was working flawless with only the 1.8GB of the available 4GB RAM was being utilised. The performance is clearly comparable to all of the Snapdragon-toting flagship devices, but at the impressively low price.

The native chrome browser renders out pages superfast on WiFi as well as on the data connection. And the kinetic scrolling is very responsive, even if we have numerous tabs loaded in the browser. Similarly the pinch-to-zoom works superquick and smooth. At the highest zoom, the text rendering is also sharp, making it a great device to read through number of webpages or even some kindle eBooks.

Even though AnTuTu predicted this device being a gaming beast, we wanted to test it out its real-world performance. The frame rates were consistently high for the games like Gun Bros 2, Bomb Squad & Tiny troopers. The same games performed great even on the online and local multiplayers.

For up to 25 minutes, the device did not heat up at all, which is pretty great for casual gamers. And after 30 minutes we noticed a moderate heading for graphic intensive games like Gun Bros 2 or Asphalt HD.
So the Asus Zenfone 2 lived up to its flagship title, with magnificent performance in browsing, gaming and intense multi-tasking.
