Being an almost 2-year old smartphone, Asus Zenfone 2 Deluxe still manages to offer good performance, although not that good for a smartphone that costs $586. It comes with Android 5.0 (Lollipop), with planned upgrade to 6.0 (Marshmallow) which isn’t yet out. For a smartphone with this price, at least Android 7.0 (Nougat) is expected. Nevertheless, Android 5.0 is still a good performer. On the other side, the hardware here is solid. We have three variants when it comes to CPU; Quad-core 2.3 GHz, Quad-core 1.8 GHz, and Quad-core 2.5 GHz. These CPUs are head-to-head when it comes to performance.
The PowerVR G6430 GPU isn’t that great, but 4 GB of RAM is a great addition to this almost 2-year-old smartphone. It’s important to mention that Asus Zenfone 2 Deluxe is a big and robust smartphone, with 5.5″ display and full HD resolution. It’s also 10.9mm thick which is very thick for the phone of this size, so if you have small hands, take care.
When i first bought this phone it was because of its design. I didn't know any of the specs or similar, but now i'm glad i bought it. It has an amazing 1080p display which i like, and since i'm not a demanding user it works well for me. 4 GB of RAM would be more than enough even for demanding users.
