Asus ZenFone 5 vs Samsung Galaxy S4 vs LG G2: specs comparison

Asus hasn't had a serious smartphone offering for quite a while now (that's if we don't count the Padfone, and we don't), but it seems like the time has finally come for the manufacturer to unleash a brand new handset line. Enter the ZenFone! Asus' latest family of smartphones includes three models - the ZenFone 4, ZenFone 5 and ZenFone 6, none of which being particularly high-end, but the 5" and 6" models shaping up as quite decent upper mid-range packages with their 720p displays and Intel CPUs.

Anyways, let's take a look at how Asus' new ZenFone 5 — which can be considered the most mainstream product of the trio — fares against some formidable opponents such as the Galaxy S4 and the G2. Naturally, since we're comparing it to two flagship devices, the ZenFone 5 will understandably lag behind its opponents in the specs race, but if you think about it, that's still going to be quite an interesting comparison, as it's going to give us a hint of just how close to last year's premium experience one can get with this new crop of affordable Android smartphones. After all, the ZenFone 5 is expected to be priced at $149 off contract, making it quite an alluring proposition.

Unfair!! Two of the above phones cost more than thrice as much as the third one!! Compare it to Moto G or Galaxy S Duo 2 or Optimus L5 II!!

These phones are not in the same level. The Zen 5 obviously sucks comparing to the other two. It's a nice phone pricewise though. Comparing it to some cheapo phones would make more sense.

PA, please fix the picture above. It's padfone mini instead of zenfone 5.

Asus should have made it a highend phone with 1080, 2800-3k battery, and 2-3 gb of ram.

No, I see the point. It's to get it into as many hands as possible. But I would actually like to see a higher spec'd version of the phone. It actually seems kinda nice.

Unfair! Galaxy S4 looks cheap & ugly. But ZenFone 5 looks premium & well designed

Ummmm, I thought that ZenFone won't be here. You know Asus has a bad reputation is smartphone race. It's Android race, not PC motherboard. Lol.
