ZenFone 4 Pro uses dual camera and the main camera is equipped with Sony’s flagship IMX362 sensor, 2x optical zoom, 10xdigital zoom lens. The same scenery is used as the test environment to take daytime and nighttime photos for comparison. In terms of ISO performance, the zoom mode should have better performance for night shooting, but using zooming to take photos during daytime when there’s sufficient light is even better. Even the captions on the Taipei 101 building can be clearly taken.

The flagship ZenFone 4 Pro dual camera phone released by ASUS runs very smoothly whether for apps or games thanks to the Qualcomm 835 8-core processor. A large 5.5-inch screen is used on the exterior with ultra-narrow frames of only 2.1 millimeter. Another great thing is that the width of ZenFone 4 Pro is reduced this time so that users won’t have to worry about dropping the phone because it is too wide. It also feels a lot better and more convenient for single-hand operations.

The camera function includes 2x optical zoom, and the photos taken with the 16 megapixel camera are almost as good as the ones taken with professional cameras. And for the recording, if you have taken a close look at the ZenFone 4 Pro sunset time lapse video, you will realize that the phone will automatically adjust the exposure and ISO, which caused the subject to be out of focus due to the automatic adjustment during recording; I suggest they enable the selection of manual or auto modes for this. The next thing is that extremely durable sapphire glass is used for the lens of both the cameras. This is very thoughtful because it can prevent the lens from getting scratched and affecting the quality of shooting.

As for the power, it uses a 3600mAh lithium battery so power is really not something you have to worry about. I spent an entire day recording videos, taking photos, answering calls and using apps with it, and by the time I got home at 10pm, it still had about 20% of battery power remaining. Then I used the genuine USB charger of ZenFone 4 Pro that provides18W (9V/2A) quick charge, and the battery quickly charged to 100% again in less than 90 minutes.
