zenfone 3 ultra review

Completing the ZenFone 3 series is the ZenFone 3 Ultra, a phablet with a 6.8-inch screen. Bearing the same 23 MP camera and an all-metal unibody similar to flagship smartphone ZenFone 3 Deluxe, the Ultra sports a Qualcomm Snapdragon 652 SoC, a dedicated, physical 4K video processor, and a 4600 mAh battery that can reverse-charge your other devices.

As a multimedia device best for watching videos, it is also the only smartphone in the ZenFone 3 series to have dual-channel, left and right loudspeakers.

We were able to go hands-on with an early engineering at Computex 2016 in Taipei, Taiwan.

  1. Brightness is comparable. Note that the Galaxy A9 has a Super AMOLED display which produces better contrast than the ZenFone 3 Ultra. On the other hand, the ZenFone 3 Ultra sports a dedicated 4k video processor which produces smoother frame rates.
