The Zenfone 5 is the middle child of Asus' budget smartphone line. Like its siblings, it has rounded edges and, besides the metal band on the bottom of the phone, is made entirely of plastic. Despite the fairly budget materials, reviewers compliment the build quality and premium feel of the device.
Front and center of the Zenfone 5 is its 5-inch, 720 pixel resolution display. While its 294ppi pixel density might lag behind that of flagship phones, Techspot adds, "…it's a challenge to distinguish individual pixels and generally images and text look great." For an entry level device, critics were fairly impressed with the quality of the display as it offers good viewing angles, decent contrast and good color accuracy and quality.
Specs-wise, the phone comes with a dual-core 1.6GHz processor, 2GB of RAM and up to 16GB of internal storage. When compared to other phones in benchmark tests, the Zenfone 5 performed around the same as the Sony Xperia T3 and worse than the Nexus 5. Still, when tested under normal conditions, experts did not detect any lag during light operations. Under more strenuous circumstances, such as playing 3D games, Trusted Reviews states, "…[it] over-stretches itself on some occasions…There are some frame rate drops…" As with the rest of the phone, the battery life didn't blow its competitors out of the water, but it did last reviewers around 10 hours with light usage. However, when 3G and another SIM are added to the mix, battery life dropped to around 8 hours.
Around the back is the Zenfone 5's main 8MP camera, which comes with Asus' PixelMaster technology. According to Asus, PixelMaster combines software, hardware and optical design for better quality images. When put to the test, most critics agree that the photos were crisp with a good amount of detail. Unfortunately, they also noticed that the shutter speed was fairly slow and many images tended to be overexposed. Still, NDTV notes, "the Zenfone 5 features an excellent camera for the price, but don't expect it to match the quality for more expensive phones…"
Despite a couple qualms reviewers had with the phone, overall they consider it a great value phone. Android Authority states, "For a budget smartphone, it's got a lot of good things going for it…"

- Andrew Williams, TrustedReviewsThere are a couple of little bits to tweak in the Asus Zenfone 5, but the value on offer here is fantastic. Other 5-inch phones at the price don’t get you screens anywhere near as good as this.

- James Norton, TechRadarIf you are not concerned about 4G or being a version behind on the software, the ZenFone 5 is very easy to recommend.
