With the main feature of a huge 5.7 inch screen, the Zenfone 3 Deluxe lets imagine, at first glance, that it will be among the most massive devices on the market. In hand, the observation is very different. The device is ultra-thin (7.5 mm) and the Asus engineers have even paid for the luxury of designing a smartphone smaller than the iPhone 7 Plus (with an aging design, it is true), for a significantly more screen. tall.
Another feat of Asus, machining a truly unibody metal shell. Understand by this that there is no hollowed out part on the back of the device or plastic band to better convey the waves necessary for the 4G connection. To our knowledge, this is the first smartphone model to offer an all-metal design, without any impact on reception quality having been noticed. Even the iPhone 7 Plus, which has removed the plastic strips from its metal back, keeps two on the top and bottom of its case.
A well-managed Snapdragon 820
On the screen side, the 5.7-inch Full HD Super Amoled panel is also a success. In addition to the perfect contrast allowed by this technology, the screen brightness is very good (536 cd / m²), quite close to what the best Galaxy can offer. What make this screen readable, even in direct sunlight, outdoors.
Nothing to say either about the general power delivered by the Snadragon 820 processor clocked at 2.15 GHz. Supported by an Adreno 530 graphics chip, it offers the Zenfone 3 Deluxe a display of more than 58 images per second on average when evaluated with the Epic Citadel application. Asus also succeeds in maintaining stable performance with this lareview Qualcomm processor, even after several tens of minutes of solicitation and without excessive heating. Mobile players should find their account!
The ZenUI overlay still as overloaded
This mastered power offers impeccable navigation fluidity within the interface of the Zenfone 3 Deluxe. Unfortunately, we still regret as much the overloaded aspect of the ZenUI 2.0 overlay, certainly not the best in the Android world. Even if Asus assures us to work on its simplification, it remains for the moment always as complex. However, it allows it to be complete, as evidenced by the photo menu which includes a manual mode. But the Taiwanese manufacturer also sometimes forgets that the best is the enemy of the good.
Besides, Asus does very well in photography, providing excellent performance in broad daylight (it thus places itself in a very good position in our top 10 photo smartphones) and of good quality in low light. In video, the stabilizer works well and jerks and deformations are very rare.
Finally, we would have liked the 3000 mAh battery to provide better endurance to this Deluxe, which turns off after only 7 h 23 after the launch of our versatile autonomy review. Results unfortunately quite consistent with those obtained with other models equipped with the Snapdragon 820, starting with the LG G5 or the HTC 10. The Deluxe Special Edition, equipped with the Snapdragon 821 (which manages energy saving better as we has seen it on the OnePlus 3T) and whose launch is planned for the very end of the year will undoubtedly solve the problem. But it will cost 100 euros more than the Deluxe.
It is all the more regrettable that the Zenfone 3 Deluxe proves to be efficient in communications with a result of 9:04 p.m.
