Asus Zenfone 5 Review

May 29, 2014

You can't expect to win them all, especially at this particular price point.

  • Build Quality
  • Display
  • Useful features
  • Camera
  • Battery life
  • Sluggish performance
The Zenfone 5 has a lot of great qualities from hardware to software but the laggy performance will be hard to overcome.  So unless ASUS addresses it with a software update, I would hold off on making a purchase for now.  

The ASUS Zenfone 5 is the middle child of ASUS’ low cost line of smartphones but for being a budget phone it comes packed with some very respectable hardware and specifications.  The design is very simplistic with rounded corners, flat sides, and a curved  back with a matte finish allowing the phone to sit very comfortably in the hand.  It’s made entirely of plastic with the exception of the metal band along the bottom chin to give the phone a slightly more premium look.  The 5 inch display coming in a 720p resolution pales in comparison to the 1080p panels on high end flagships but it’s still nothing to scoff at.  Colors are accurate, viewing angles are great, and graphics and text still look very sharp making this an overall enjoyable display.Asus Zenfone 5-24

Inside, the Zenfone 5 is being powered by a a dual-core Intel Atom processor clocked at 2 GHz backed by 2 GB of RAM instead of the usual ARM processors that can be found in virtually every android phone.  Performance through general day to day tasks such as swiping through home screens and opening up apps are smooth but the phone suffers from stability issues with certain apps and gaming is very choppy and sluggish making games difficult to enjoy.  These issues could most likely be alleviated with a software update but this is how it stands for now.

Around back is an 8 megapixel camera with ASUS’ PixelMaster technology and an aperture of f/2.0 making it great in low light.  The camera app itself while not the most simplistic comes a lot a manual controls for serious smartphone photography and a slew of different shooting modes like panorama, HDR, depth of field, and a dedicated selfie mode.  All of these features make the camera very fun to play with but the actual picture quality is decent at best.  Colors are very accurate and you can snap some great looking shots provided the lighting conditions are right but the camera suffers from poor dynamic range creating some overexposed lights and underexposed darks.

Battery life also leaves a lot to be desire as the 2,110 mAh battery isn’t enough to make this phone last throughout a full day without carefully monitoring your usage.  Luckily, ASUS has included some power management options to help you get the most out of the battery should you go for an extended period of time without a charger.

On the software side the Zenfone 5 comes with Android 4.3 Jellybean with a promise of being updated to KitKat by ASUS but no word on when that will happen.  On top of Android is ASUS’s Zen UI that is very clean, flat, and colorful.  It comes packed with a lot of extra functionality without being gimmicky and adds to the Android experience without taking away the core features of Android.

ASUS announced the Zenfone 5 with a price tag of $149.99 but if you’re inside the United States you’ll be hard pressed to find it for this price as it’s not officially available in the U.S. as of right now meaning you’ll have to pay a slight premium to import it.  Connectivity wise there is no LTE but it does support 3g on AT&T and T-Mobile in the United States should you decide to pick one up.  For a budget smartphone it’s got a lot of good things going for it like the solid build quality, a decent looking display, and a handful of very useful software features.  It does fall short in some areas like the performance and battery life which could potentially be improved with software updates but you can’t expect to win them all especially at this particular price point.

    I like these shorter reviews, the video says enough. So much competition at the low end these days! I think I’ll stick with my Moto G though. But love seeing competition at the ‘low end’ :)

  • Fauzan Adhi Rachman

    It sold like nut in Indonesia cause the moto g NEVER come officially. F***k yeah.
    it’s very cheap for a middle phone Rp 1,9 Million

      I like Indonesia. Everybody’s a millionaire.

    lots of people have commented on this video stating that the moto G was better but I still don’t get understand why. Anyone care to explain?
    This is how they stack up against each other:

    Zenfone 5 vs Moto G

    -2gb vs 1gb RAM
    -Dual SIM vs one SIM slot (even if you think its useless for you, its better to at least be able to use Dual-sim rather than not be able to do so at all)
    -Both have un-removable batteries
    -Both have 8/16 GB internal memory variants (plus Zenfone 5 offers a variant with 32GB internal memory in Taiwan)
    -MicroSD expansion (up to 64GB i think?) vs no MicroSD expansion at all
    -5″ screen vs 4.5″ screen (im not saying that one is superior to the other)
    -Both with 720p displays
    -Same weight class (about 145 grams)
    -Zenfone 5 listed at 5.5-10.3mm thick vs 11.6mm on moto G
    -Zenfone 5 is about 19mm longer (disadvantage for the zenfone imo. noticbly longer than typical phones with 5″ displays)
    -$130/$165 vs $175/$199 list price (not entirely about moto G but the zenfone prices are based on what Asus is pricing them at on their Taiwanese website)
    -8MP camera vs 5MP camera, plus zenfone has ‘Pixelmaster’ which sounds like a pathetic gimmicky marketing thing but is actually really useful (if youre interested read some articles/watch videos about Pixelmaster on the zenfones)
    -2MP vs 1.3MP front-facing camera (effectively no difference but still)
    -4.3 jelly bean with promised update to kitkat vs 4.4.2 kitkat (although im not sure asus will actually deliver on their promise)
    -Intel Dual core 2Ghz processor and Atom chipset vs quad core 1.2Ghz cortex-A7 and snapdragon 400.
    -From what i’ve read, Moto G battery life is pretty darn good whereas the Zenfone’s battery life is average (but I dont think its as bad as this video makes it out to be? one review i read stated that it lasted 6 hours while looping a 720p video on full brightness, etc. while flagships like the xperia Z2, gs5 etc. scored 9 hours. So its not great but its not abysmal either).

    So I mean I really dont understand why people still find the Moto G superior.

    I mean from what I see, the zenfone outclasses the moto G in almost every department – larger screen (if thats your thing, although a 5″ display usually wont be considered too big), similar weight despite larger size, Dual-SIM functionality, MicroSD expansion (HUGE plus for me), cheaper (if you happen to be able to buy it for their listed 150$ price), superior camera that arguably even is superior to some of the cameras on 2014 flagship devices due to its ability to make decent photos in extremely low light situations. And on top of that, i personally find that the Zenfone 5’s design is superior to the Moto G but obviously that’s not something quantifiable, unlike the specs i listed above.

    On the other hand, you have the Moto G which is already running on Kitkat, perhaps you could say that it has a better brand (although ASUS’ brandname isnt too shabby either), and its pretty clear that the snapdragon 400 and Cortex A-7 is superior to the intel setup. Then again, i’d imagine that the average person not willing to spend over $200 for a phone won’t be doing anything intensive of their phone. On top of that the Moto G’s already out whereas even in Taiwan the Zenfone’s launch date STILL keeps getting pushed back so yea..

    Overall though, I think the advantages that the Zenfone 5 has over the Moto G significantly outweigh the advantages that the Moto G has over the zenfone 5. So that’s why i dont understand why people keep claiming that the Moto G is better. If you have some time to wait for the Zenfone 5 to actually become available (at least in Taiwan, idk about other places), then it seems that the Zenfone 5 is the clear winner.

      Battery life and overall system performance are incredibly important for most people. Moto G seems like a much more reliable device.

    • John

      The user experience, you know. That’s why people said that moto g is a better phone.

    • Arjunsinh Jadeja

      Exactly dude. I wanted to write something like this myself in many websites but was too lazy. You’re correct at every point. And for user experience, believe me ZenUI is far-far better than Stock. I know I am saying something, but I can backup it up if required!

    • Saurabh

      not only moto g, but every almost phone in this range is better….
      reason being BATTERY…..these zfones are the worst thing ever produced, its like take my ferrari having a fuel tank of 10 litres.
      So. even a tata nano is better than that.
      Its not about people , in future, some china crap will release phones better than redmi 1s in features with tons of problems, still fools will buy that, why cuz its cheap…..simple, that’s why companies sell their products in india, tremendously.
      Mentalities of people like u………..hails foreign companies…..nice buying …….lol

  • aditya243

    This review is like a transcript of whatever the guy says in the review on youtube…Come on !!The written review should atleast be more detailed…BTW how come moto g with comparable(arguably better) specs gets a good rating while this one does n’t ?

  • Halfey Halphstein

    One thing I found ‘missing’ from mine is the ability to recognize ANY pen/pencil as stylus (ala Sony Xperia Z Ultra). Months ago Asus claimed that the phone display is capable of recognizing regular pen/pencil as a stylus thus eliminates the need to use the ‘fat’ stylus. However I found mine did not work at all though it managed to work with gloved fingers. I wonder if I received a faulty unit or something.

    This phone is not at all sluggish. Android authority is publishing wrong information. Few games are not optimized for all platforms hence can see those artifact(View all videos in youtube to see gaming Performance). Overall a good phone than crappy motoG. Android Authority Accept ur fault in reviewing.

  • Spencer Walker

    Please update review the lte version has a Qualcomm 400 sane as moto g now there is almost no reason to pick moto g over zenfone except maybe ui

  • rrssd
